Inside Brazil’s Incredible Tarantula Diversity

Brazil is considered the most biodiverse country on Earth, with 15%-20% of the world’s biodiversity. The Amazon rainforest, the Cerrado savannas, the semi-arid Caatinga, the coastal Atlantic Forest, the wetlands of the Pantanal, and the Pampas grasslands are home to over 120,000 animals and over 4,000 plants. Brazil is home to the greatest diversity of tarantulas in the world, with over 200 species.

The following list includes currently recognized tarantula species native to Brazil according to the World Spider Catalog as of December 2025. An asterisk after the tarantula’s name indicates that it is the type species. Many species do not have common names because they are newly discovered or have not been formally described. For lesser-known species, common names are typically unnecessary. Where possible, we have included common names, but scientific names provide the most precise identification. See our complete list of tarantula species for a comprehensive reference of all tarantula species.

Acanthoscurria Ausserer, 1871

Members of the genus Acanthoscurria are primarily distinguished from other genera by the presence of stridulatory setae (noise-making hairs). They can grow to large sizes, with leg spans measuring up to 8 inches. These spiders often have dark bodies with reddish-tinted setae on their abdomen and legs, plus light-colored bands at the leg joints. Tarantulas in this genus frequently build tube-like burrows under rocks or in ravines. Some spiders may also be found in silken retreats inside tree trunks or fallen logs. In Brazil, many Acanthoscurria species inhabit the Amazon in the states of Amazonas, Mato Grosso, Pará, Rondônia, and Roraima.

Amazonius Cifuentes & Bertani, 2022

Amazonius is a genus of arboreal tarantulas found in the Amazon rainforest. They are medium-sized spiders that can reach leg spans of up to around 5 inches. Amazonius are similar to Psalmopeous in the presence of stridulatory setae on their mouthparts, although the hairs are slim and more numerous in Amazonius. Brazilian Amazonius species are generally shades of brown to brownish-orange. The cephalothorax and abdomen are covered in short, dense, dark setae with long, light reddish setae scattered on the abdomen. Their legs are also covered in dense setae.

Arboriticus Borges & Bertani, 2025

Arboriticus is a recently described genus of medium to large arboreal tarantulas. A. giganticus is the largest species discovered to date, with a leg span of around 6.4 inches. Females were also found to have a thicker, stronger leg IV, covered in stiff setae. They are often muted shades of brown, grey, and olive with light leg bands. Specimens have been observed on tree trunks and walking along branches. Arboriticus spiders create their silken retreats in the cavities of trees up to 8 feet off the ground. These spiders are found in the Brazilian Atlantic Forest from northeastern to southeastern Brazil, occasionally in highly deforested regions.

Avicularia Lamarck, 1818

Members of the genus Avicularia are small to medium-sized arboreal tarantulas, often favoring the mid-to-upper canopy of the rainforests for their retreats. In the Brazilian Amazon, Avicularia retreats are frequently found at the base of palm tree leaves. These spiders generally have long setae on their legs and abdomens, as well as urticating setae type II on the top of the abdomen. Type II hairs are primarily transferred through direct contact, as they are too heavy to be carried by air. Avicularia species are some of the most in-demand tarantulas in the pet trade due to their unique, vibrant color patterns and metallic sheen as juveniles.

Bumba Pérez-Miles, Bonaldo & Miglio, 2014

One way to distinguish the genus Bumba is the type IV urticating setae on their abdomens, which are short, very fine hairs with barbs and pointed tips. They are generally medium-sized terrestrial tarantulas that reach leg spans of 4-6 inches. Most species are shades of brown to black overall, but B. horrida has a vivid red cephalothorax with a black abdomen and legs. Some species may also display abdominal patterns. In Brazil, these spiders occur in the states of Pará, Rondônia, Mato Grosso, Amazonas, Roraima, Goiás, Mato Grosso do Sul, Minas Gerais, Bahía, and São Paulo.

Catanduba Yamamoto, Lucas & Brescovit, 2012

Catanduba are small tarantulas that are mainly distinguished from other genera by the morphology of the male genitalia and the triangular-shaped nodule on the base of metatarsus I in males. These nodules are believed to assist in holding the female’s fangs during mating. Catanduba species are generally shades of brown with dark abdomens and long yellowish or orange setae. Some species may also have stripes extending down the sides of the abdomen. These burrowing tarantulas primarily occur in the tropical savannas of the Cerrado in central Brazil, but some species can also be found in the Atlantic Forest and in the semi-arid Caatinga scrub forest.

Catumiri Guadanucci, 2004

Tarantulas in the genus Catumiri are very small terrestrial spiders. With leg spans between 2 and 3 inches, they are considered to be among the smallest tarantula species. These spiders have few or no urticating hairs, which is uncommon in New World tarantulas. C. chicaoi is known from Bahía state in Northeastern Brazil. It is described as having a reddish-brown carapace and a black abdomen. Females are distinguished by 4–5 pairs of small white spots on the top of the abdomen. C. parvum is known from Santa Catarina and Rio Grande do Sul states in the South. It has a brown body with brown to brownish-grey legs and a coppery-brown carapace. C. petropolium is known from Rio de Janeiro state in the Southeast. It has a brown body with darker, square-shaped abdominal markings.

Crypsidromus Ausserer, 1871

In 2023, the genus Crypsidromus was removed from synonymy with Lasiodora. Members of the Crypsidromus genus are distinguished by a line of setae dividing tarsi IV and the lack of tibial spurs on mature males. They are often shades of brown or grey with long, reddish-orange setae scattered on the legs and abdomen. Some Crypsidromus species have abdominal patterns and/or a contrastingly colored cephalothorax. C. isabellinus is known from southeastern Brazil. C. multicuspidatus was collected in the state of Rio de Janeiro, while C nondescriptus was found in São Paulo.

Cyclosternum Ausserer, 1871

Members of the genus Cyclosternum are typically small to medium-sized tarantulas found in forests and grasslands in tropical regions across Central and South America. Researchers consider the genus problematic due to historically insufficient descriptions, contradictory illustrations, inadequate or absent associations between the sexes, erroneous type localities, and intersecting distributions. There is limited public documentation regarding many Cyclosternum tarantulas, including C. garbei, and species-level identification is challenging.

• Cyclosternum garbei (Mello-Leitão, 1923) – Brazil

Cyriocosmus Simon, 1903

Members of the genus Cyriocosmus are found across subtropical South America. They occur in both lowland rainforests of the Amazon and high-elevation forests up to 9,842 feet. The genus includes small to medium-sized spiders from 0.39 inches to 1.25 inches in total body length, not including the chelicerae and spinnerets. Cyriocosmus spiders may have a bicolor reddish-brown and black or a uniform black carapace with a dark colored or laterally-striped abdomen. The legs may have pale stripes. They are covered with short black setae and long, pale guard setae. They also have a glossy, often heart-shaped reddish-brown spot of type III urticating setae on the abdomen. Their retreats are typically found under logs, rocks, leaf litter, or other forest debris.

Cyrtogrammomma Pocock, 1895

The genus Cyrtogrammomma includes three small tarantulas found in Guyana and Brazil. They reach a maximum total body length of around 0.55 inches. These tarantulas are generally shades of light to dark brown with lighter setae. C. frevo is differentiated by 8 central spots and lateral stripes on the abdomen. They dig silk-lined retreats in the ground, covered with a camouflaged trapdoor. C. monticola was first described from Monte Roraima, a flat-topped mountain, or tepuis, that is located where Guyana, Brazil, and Venezuela intersect. This spider has also been recorded in caves in the state of Pará. C. frevo is known from the states of Alagoas, Bahía, and Pernambuco.

Devicarina Peñaherrera-R., Sherwood, Gabriel, Léon-E., Rollard, Leguin, Brescovit & Lucas, 2025

The genus Devicarina was recently created to accommodate two relatively small burrowing species that had been misplaced in Hapalopus. D. akroa is shades of orange and has a beige abdomen with a dark, longitudinal band. Females are distinguished by their dark carapace. D. guidonae is also shades of orange, but they have dark abdomens with five beige stripes. D. akroa was collected in Serra das Confusões National Park, while D. guidonae is known from the Serra da Capivara National Park, both from Piauí state in Northeastern Brazil. These parks are in the Caatinga biome, characterized by semi-arid shrubland and thorn forests.

Dolichothele Mello-Leitão, 1923

Dolichothele tarantulas are small burrowing spiders that typically reach leg spans of 3 to 4 inches. These spiders also lack urticating setae in both sexes. They can be found in a variety of environments across Brazil, including the savanna vegetation of the Cerrado in Central-Western Brazil, the Amazon region, cave habitats in the state of Pará, rocky savanna-like areas of the Espinhaço Mountains, and the Atlantic Forest region, among others. These spiders are known to create intricate, heavily-webbed tunnels under logs and rocks. Dolichothele species have distinct color patterns, sometimes among the same species depending on geographical location.

Ephebopus Simon, 1892

Members of the genus Ephebopus are medium-sized tarantulas that generally reach leg spans of 4.5-6 inches. They typically excavate tube-like burrows under logs, rocks, or tree roots in lowland and upland rainforests, as well as grasslands above flood plains. However, E. murinus has an arboreal stage during development, inhabiting silk tubes in vegetation. Ephebopus tarantulas are commonly referred to as “skeleton tarantulas” due to the light-colored markings on their dark legs, which are said to resemble bones. Ephebopus tarantulas are distinguished from other genera by the presence of type V setae, which are very short, barbed hairs located on the pedipalp femora instead of the abdomen like other New World tarantulas. Type V setae are light, and easily detach by rubbing the palps with the chelicerae.

Eupalaestrus Pocock, 1901

Eupalaestrus tarantulas are medium to large terrestrial spiders, reaching leg spans of 5-6 inches. They often have dark brown bodies, with pale banding on their leg joints or other color patterns on their legs. They have urticating setae of types I and III and an abundance of setae on their legs and abdomen. Some species also have a thickened metatarsus IV. Eupalaestrus species tend to dig deep burrows in open grasslands inside forest habitats. In Brazil, they frequently occur in the transitional areas of the Atlantic Forest and Pampas grasslands in the states of Paraná, Rio Grande do Sul, and Santa Catarina in southern Brazil.

Grammostola Simon, 1892

Grammostola tarantulas are medium to large-sized terrestrial spiders. They have a maximum leg span of 8 or more inches in species such as G. iheringi, often considered to be the largest Grammostola tarantula. These spiders tend to have dark bodies, longitudinal markings on their knees, and dense, reddish-tinted setae. In Brazil, Grammostola species are distributed throughout the southern part of the country, particularly in the state of Rio Grande do Sul, where six currently known species have been documented. These spiders tend to dig deep burrows along forest edges or in open grasslands, but some species create their retreats under leaf litter, rocks, roots, or other vegetation.

Guyruita Guadanucci, Lucas, Indicatti & Yamamoto, 2007

Guyruita tarantulas are usually small, with leg spans that do not exceed 4 inches. They are generally shades of brown or grey, and all species except G. atlantica have abdominal patterns. However, all Guyruita species lack urticating setae. These spiders are found in the Atlantic Forest region in Alagoas, Bahía, Paraíba, Espírito Santo, Rio Grande do Norte, and Sergipe states. They inhabit the Cerrado savannas in the states of Distrito Federal, Goiás, Piauí, Maranhão, and Tocantins. They can also be found in the Amazon Forest and in the iron ore caves (G. metallophila) in Carajás region in the state of Pará. These burrowing spiders are often found living under rocks.

Holothele Karsch, 1879

Members of the genus Holothele are small terrestrial tarantulas that lack urticating setae on their abdomens. They are widespread across northern South America and the Caribbean islands. H. longipes is the only species recorded for Brazil. It has bluish-grey legs with darker femora, and the legs are covered in black setae with patches of orange and blue. Its cephalothorax and chelicerae are are covered in long, dense, peachy-pink setae, while its abdomen is covered with short, dense, black setae and longer orange setae. H. longipes has been found in the humid forests of the Amazon region. They often dig deep, heavily webbed burrows, sometimes using rotting logs or other organic debris.

  • Common name: Trinidad pink tarantula

Homoeomma Ausserer, 1871

Members of the genus Homoeomma are distingusihed by the morphology of their genitalia in combination with the presence of urticating setae types III and IV, which are short, fine hairs with pointed, barbed tips. This type of setae is less irritating to humans than type III hairs, which are longer and more potent. They are small tarantulas with leg spans of 2-4 inches. These dwarf spiders generally make shallow retreats under stones in areas with dense vegetation. Many Homoeomma species have dark bodies with vivid orange or reddish setae on the abdomen. Many Brazilian species inhabit the Atlantic Forest in southeastern states such as Rio de Janeiro, as well as Bahía in the northeast.

Iridopelma Pocock, 1901

Members of the arboreal genus Iridopelma range from small (I. zorodes) to large (I. vanini). Males differ from other Aviculariinae genera by the presence of tibial spurs on both legs I and II. Females differ by having a strongly forward-curving anterior eye row. Type II urticating hair is also present on the abdomen of males and females (except adult females of I. marcoi). Iridopelma are mostly found in Brazilian Atlantic rainforest in Northeastern Brazil, from the Reconcave region in Bahía State northwards. Some species build retreats by connecting leaves with silk, while others make their retreats in bromeliads (a family of flowering, tropical plants). Most species are shades of brown, grey, or black, and some species retain the abdominal patterns found in juveniles.

Lasiodora C. L. Koch, 1850

The genus Lasiodora was revised in 2023 and reduced to just 7 species. It is primarily diagnosed by the presence of stridulating setae on coxae I and II. These spiders can grow very large, with leg spans reaching 8 to 10 inches. They generally have dark bodies, often with banding around the leg joints and/or longitudinal stripes on their legs. Some species, such as L. klugi and L. subcanens have long setae on their legs and abdomens, giving them a fuzzy appearance. They have been recorded in forest habitats, from the semi-arid scrubby forest of the Caatinga to the Atlantic rainforest in the states of Sergipe, Minas Gerais, Bahia, Goiás, and Espírito Santo.

Neischnocolus Petrunkevitch, 1925

There are two Neischnocolus tarantulas found in Brazil: N. caxiuana, found in the state of Pará, and N. valentinae, collected in the state of Amazonas. Neischnocolus species are small burrowing spiders. Both sexes are brown or reddish-brown overall with cream-colored bands at their leg joints. They have either dark brown or reddish-brown setae on their legs and their dark abdomens are covered in long, reddish setae. Some Neischnocolus species may also have indistinct abdominal patterns. Members of Neischnocolus can be distinguished from nearly all other genera by the combination of their specific genitalia morphology and the presence of type I (subtype d) urticating setae.

Nhandu Lucas, 1983 

Tarantulas in the genus Nhandu are primarily distinguished by the morphology of the genitalia and the tibial apophysis (protrusion). They typically have dark bodies with long, woolly, reddish setae on their abdomens and legs. They also have banded legs with dark femora. Species in this genus inhabit tropical and subtropical forests, as well as grasslands. They are medium to large-sized terrestrial spiders that often construct their burrows under rocks.

Notahapalopus Sherwood, Gabriel, Peñaherrera-R., Osorio, Benavides, Hörweg, Brescovit & Lucas, 2024

The genus Notahapalopus was created to house one newly described species and three species that were transferred from Hapalopus. These small spiders were moved from Hapalopus to Notahapalopus based on the morphology of the tibia and the male reproductive organ. Some species also lack the spotted and/or striped abdomen found in Hapalopus. N. aymara has been recorded in the southern part of the Amazonian forest, as well as in caves in the Serra Norte de Carajás iron ore mining complex in the state of Pará. N. parauapebas and N. serrapelada have been recorded in the montane region of the Parnaiba basin. The species N. serrapelada has also been recorded in caves in the Serra Leste mining complex in Pará state, near the famous Serra Pelada gold mine, where it got its name.

Pachistopelma Pocock, 1901

Pachistopelma are small arboreal tarantulas that mainly occur in the coastal region of Northeastern Brazil, from the state of Rio Grande do Norte to the state of Bahia. These tarantulas make their retreats exclusively inside bromeliads. They are distinguished by a straight or slightly forward-curving first eye row, the lack of leg spines, a spiny spur on tibia I in males, and the presence of urticating type II hair on the abdomen (except in mature females, whose abdomens are also flattened). P. bromelicola are blackish with pale setae, while P. rufonigrum are dark brown with pinkish setae. Both species lack the metallic sheen and abdominal patterns found in juveniles.

• Pachistopelma rufonigrum* Pocock, 1901 – Brazil

Pamphobeteus Pocock, 1901

Pamphobeteus species generally have dark bodies with colored stripes on either side of the cephalic region (head). These markings may connect to pink or purple radial stripes on the carapace. These spiders may also have longitudinal stripes on their legs. Members of Pamphobeteus are medium to very large tarantulas with a total body size that can reach up to 3.78 inches and a leg span of up to 9 inches. They can primarily be found in the Brazilian Amazon forest where they typically inhabit burrows and other natural cavities.

Parvicarina Galleti-Lima, Hamilton, Borges & Guadanucci, 2023

Pterinopelma felipeleitei was transferred to the recently established monotypic genus Parvicarina based on differences in morphology and phylogeny. The holotype male has a body length of approximately 1.57 inches, and its longest legs (pair IV) measure 2.23 inches. Its carapace and legs are black with distinctive pale bands on the leg joints and light-colored longitudinal stripes on its legs. The abdomen is black with long brown setae. P. felipeleitei is found in the Espinhaço Mountain Range in the central part of the state of Minas Gerais. It occurs in the highlands above 3,608 feet in open, rocky fields.

• Parvicarina felipeleitei* (Bertani & Leal, 2016) – Brazil

Phormictopus Pocock, 1901

Members of the genus Phormictopus are distinguished from most genera by club-like stridulatory setae on the trochanters and coxae of palps and legs I. They are typically large, with leg spans measuring 7-8 inches, although females of some species may grow larger. Some Phormictopus tarantulas have iridescent or metallic colors. Nearly all of the species in this genus are found in Cuba and Hispaniola, so it is likely that these spiders are restricted to the West Indies, and the Brazilian species are misplaced. These spiders tend to excavate silk-lined burrows in forested areas, often beneath rocks.

Plesiopelma Pocock, 1901

Plesiopelma tarantulas are small to medium-sized spiders found in southern parts of South America, including Brazil. The type locality is unknown for some Brazilian species, but P. insulare is known from the state of São Paulo, while P. physopus is known from the state of Paraíba. Most Plesiopelma species can be characterized by the long setae that converges at a central point on top of the abdomen. The tarantulas in this genus are generally found in mountainous regions. They often create their silk-lined burrows under rocks, sometimes also covering the entrance with heavy silk.

Psalmopoeus Pocock, 1895

Members of Psalmopoeus are arboreal tarantulas that lack urticating setae. They are medium to large spiders, with most species averaging leg spans of 5 to 7 inches. P. irminia is a dark grey to black tarantula with dense, dark setae, bright orange markings on its legs and palps, and a tiger-striped abdomen. It has been documented in the state of Roraima, close to the Venezuelan border. P. irminia was collected at an elevation of around 2,952 feet, along the southern border of the Paracaíma Mountains. It was found close to its tube-like retreat in a forested area near the Miang River.

• Psalmopoeus irminia Saager, 1994 – Venezuela, Guyana, Brazil
  • Common name: Venezuelan Suntiger

Pterinopelma Pocock, 1901

Pterinopelma spiders are burrowers, often found beneath leaf litter. They are distinguished from similar genera by the lack of stridulatory setae on the coxae, the segment that connects the leg to the body. Females are also distinguished by having a sternum that is at least as wide as it is long. Pterinopelma species can be found in the Atlantic forest in the state of Rio Grande do Sul (P. vitiosum), in the subtropical semi-deciduous forest of the states of Paraná and Santa Catarina, west of the Serra do Mar mountains (P. longisternale), and in the subtropical semi-deciduous forest in the northwest and central parts of Rio Grande do Sul state (P. roseum).

Schismatothele Karsch, 1879

The genus Schismatothele includes small burrowing tarantulas with no urticating setae. These spiders are primarily distinguished from other genera by the morphology of their genitalia. Males also have a swollen palpal tibia with thick spines. S. benedetti is the first recorded species from Brazil in the genus. Its carapace, palps, and legs are reddish brown and it has a light brown abdomen. This spider is known from the area around Manaus, located on the banks of the Negro River in the state of Amazonas. S. wayana has a dark brown carapace, chelicerae, and legs with a light brown abdomen. It is known from the eastern region of Pará state.

Sericopelma Ausserer, 1875

Although the original description of S. fallax lists Amazonas, Brazil as the type locality, all confirmed Sericopelma species have a distribution in Central America, specifically Costa Rica and Panama. Researchers note that an examination of the holotype shows this species does not belong to Sericopelma, but the best taxonomic placement of S. fallax outside Sericopelma has yet to be determined.

• Sericopelma fallax Mello-Leitão, 1923 – Brazil

Sickius Soares & Camargo, 1948

The genus Sickius is known from a single species, Sickius longibulbi. They are small spiders, with a total body length of around 0.86 inches in males and 0.98 inches in females. They are primarily brown overall with golden setae on the abdomen. These tarantulas dig shallow burrows covered with silk under rocks and fallen logs. This species is known for its uncommon mating behavior, where males hold the females by their first pair of legs instead of the chelicerae. Females also completely lack spermathecae, which is the internal reproductive organ where sperm is stored after mating. They are one of only two tarantula species in the world to lack this structure. S. longibulbi has a geographic distribution across a continuous range of over 600 miles, spanning both the savannas of the Cerrado and the coastal Atlantic Forest.

• Sickius longibulbi* Soares & Camargo, 1948 – Brazil

Tapinauchenius Ausserer, 1871

Tapinauchenius tarantulas are medium-sized arboreal tarantulas that lack urticating setae. They make their homes in the vegetation of the rainforest. T. gretae is known from Amazonas state. Its carapace, chelicerae, palps, legs, and abdomen are brown and covered in light brown setae. T. brunneus has been recorded in Rondônia and Mato Grosso. It is brown overall with a T-shaped marking on the abdomen. T. plumipes is known from the Cuminá River, in the state of Pará. It is primarily dark brown with a blue-violet sheen on the carapace, legs, and chelicerae. Males have a purple abdomen with a T-shaped marking, while females have a brown abdomen with violet shades and a central longitudinal line.

Tekoapora Galleti-Lima, Hamilton, Borges & Guadanucci, 2023 

Vitalius wacketi was transferred to Tekoapora, which was created due to phylogeny and morphological differences. V. wacketi is a large, terrestrial tarantula with a dark brown carapace and abdomen. It has brown legs with darker femora, pale leg rings, and longitudinal leg stripes. Its abdomen and legs are covered in long pinkish setae. This spider inhabits tropical broadleaf forests in the Serra do Mar mountains and coastal region, including nearby islands. Its distribution ranges from south of Rio de Janeiro state to the states of São Paulo, Paraná, and Santa Catarina.

Theraphosa Walckenaer, 1805

Tarantulas in the genus Theraphosa are among the largest in the world. All of the spiders in the genus can reach nearly the same size, but Theraphosa blondi, the Goliath birdeater, is widely recognized as the largest. It is also the largest spider on the planet by body length and mass. It has a total body length of 4.75 inches, leg spans of up to 12 inches, and can weigh up to 6 ounces. Theraphosa spiders are generally light to dark brown in color with long, reddish-orange setae on the legs and abdomen. They may also have longitudinal stripes on their legs. Theraphosa species dig deep, silk-lined burrows in the rainforests, sometimes under roots or rocks.

Trichopelma Simon, 1888

Trichopelma illetabile has historically been placed in the genus Trichopelma. However, recent taxonomic revisions and cladistic analyses have classified it as nomen dubium (of doubtful name), or effectively incertae sedis (of uncertain placement), as researchers suggest it is misplaced in Trichopelma. They speculate it may belong to the family Barychelidae, trapdoor spiders, in the genus Sasoninae.

• Trichopelma illetabile Simon, 1888 – Brazil

Typhochlaena C. L. Koch, 1850

Typhochlaena are very small arboreal tarantulas. They are primarily distinguished by the presence of urticating hair type II on the abdomen, the lack of tibial spurs in males, the morphology of the genitalia, and truncated sternums (the underside of the cephalothorax) that are as long or longer than they are wide. They are found in Northeastern Brazil, mostly in the Brazilian Atlantic rainforest, although T. costae occurs in drier, open environments and T. chapadensis occurs in the Chapada Diamantina mountainous region. These spiders typically build silken retreats under loose tree bark. Typhochlaena species generally have a metallic or iridescent sheen, patterned abdomens, pale bands at the leg joints, longitudinal stripes on the legs, and long setae on the legs and abdomen.

Umbyquyra Gargiulo, Brescovit & Lucas, 2018

Tarantulas in the genus Umbyquyra are primarily distinguished from other genera by the combination of the genitalia morphology and the presence of the stridulatory setae on the palpal trochanter and on leg I. Umbyquyra species generally have a total body length ranging from a maximum of 1.57 inches in males to 1.73 inches in females. They are typically dark brown overall with lighter brown legs and long, reddish or gold setae on their abdomen and legs. Both sexes have type I and III urticating hairs. Species of Umbyquyra have been recorded in the states of Acre, Pará, Goiás, Mato Grosso, Mato Grosso do Sul, Rondônia, Tocantins, and São Paulo. Some species have been located inside rotten palm trees and in tube-like burrows in dirt hills.
