Quick Take

  • The king baboon spider, Pelinobius muticus, of Kenya and Tanzania has an incredible 9-inch leg span, which is how it got the common name “king.”
  • The absence of spermathecae, the female reproductive organ, in Encyocratella olivacea is a major hurdle in the sexing process of these spiders.
  • Hysterocrates gigas possesses the uncommon ability to swim and submerge despite its terrestrial nature.
  • Males in the Satyrex genus have 2-inch palps to survive the lethal risks of the reproduction process.

There are over 140 tarantula species that inhabit the countries of Africa. There are diverse habitats across the continent, from the Sahara and Kalahari deserts to the savannas of the Serengeti, the mountain ecosystems of the Ethiopian Highlands, and the dense rainforests of the Congo. Some researchers believe that all modern tarantulas have their origins in Africa. Africa’s diversity of tarantula species is believed to result from their evolutionary history and favorable local conditions.

    • Common name: N/A
    • Distribution: Cameroon

Ceratogyrus Pocock, 1897

The rear-horned baboon spider, Ceratogyrus darlingi has a black, backward-curving horn on its carapace.

Ceratogyrus spiders are called horned baboon tarantulas, due to the distinctive horn-like protrusion on their carapace. They generally range in color from an ashy grey to dark brown and reach a leg span of 4-6 inches. They excavate deep burrows heavily lined with silk in the arid regions across southern Africa. These spiders are known to have defensive temperaments and strong venom.

Chaetopelma Ausserer, 1871

Most Chaetopelma spiders have a Mediterranean or Middle Eastern range. Chaetopelma webborum is the only Chaetopelma species found outside of that region. It is known only from the female holotype species collected in Efulen, Cameroon. Researchers believe the information provided in the original description and its occurrence far outside the usual range suggest that C. webborum is misclassified.

  • Chaetopelma webborum Smith, 1990
    • Common name: N/A
    • Distribution: Cameroon

Encyocratella Strand, 1907

Encyocratella olivacea tarantula

The Tanzanian black and olive baboon spider, Encyocratella olivacea, is brightly colored with an intricately patterned abdomen.

Encyocratella is a monotypic genus. Encyocratella olivacea is known for its olive-green, gold, and black coloring and intricate patterns on its abdomen. It is one of the few species where females lack spermathecae (sperm storage organs), which makes sexing them difficult. They are primarily an arboreal species, making elaborately webbed homes in trees. These spiders are generally defensive and have potent venom. They can reach 4.5-6 inches in leg span.

  • Encyocratella olivacea* Strand, 1907
    • Common name: Tanzanian black and olive baboon spider

Harpactira Ausserer, 1871

Harpactira pulchripes

The golden blue leg baboon spider, Harpactira pulchripes, is popular in the pet trade for its vibrant colors.

Harpactira tarantulas belong to the Harpactirinae subfamily of spiders, commonly called baboon spiders. However, tarantulas in the genus Harpactira are known to be much calmer than their aggressive cousins, although they are still very fast and have potent venom. Some species in this genus have vibrant colors, such as the golden blue leg baboon, shown above, and they are very hairy. They are medium- to large-sized tarantulas, generally reaching between 5-6 inches in leg span. These terrestrial spiders excavate elaborate, heavily webbed burrows. They are found in South Africa, with Harpactira namaquensis also found in Namibia.

Harpactirella Purcell, 1902

Harpactirella lightfooti tarantula

Like all species in the genus Harpactirella, Harpactirella lightfooti can be found in South Africa.

Spiders in the genus Harpactirella are also part of the subfamily Harpactirinae. However, Harpactirella spiders are generally smaller than others in this subfamily, and are commonly called lesser baboon spiders. The females generally reach no more than 2-4 inches in leg span. These spiders have been reported to be fast and aggressive with potent venom. In addition to size, they can be differentiated from Harpactira by the tufts of bristly hairs on their chelicerae, which are their fang-bearing mouthparts. They make silk-lined tunnels under rocks, logs, or other debris in the open, grassy plains of South Africa.

Loxomphalia Simon, 1889

Loxomphalia is known from a single species endemic to the archipelago of Zanzibar off the coast of Tanzania. They are part of the subfamily Eumenophorinae, differentiated by spiky, stridulatory setae between the coxae of leg I–IV, the parts of the leg that connect them to the body. With the exception of the genus Mascaraneus, spiders in this subfamily also have a patch of stiff setae on the femur of the pedipalps.

  • Loxomphalia rubida* Simon, 1889
    • Common name: N/A
    • Distribution: Tanzania (Zanzibar)

  • Loxoptygus coturnatus Simon, 1903
    • Common name: N/A
    • Distribution: Ethiopia
  • Loxoptygus ectypus* (Simon, 1889)
    • Common name: N/A
    • Distribution: Ethiopia

Mascaraneus Gallon, 2005

The genus Mascaraneus is only known from a single species found on Serpent Island, the most remote and inaccessible islet of Mauritius. This large spider measures approximately 1.8 inches in total body length. It is described as a uniform light mustard brown color with short, uniform setae on its abdomen. Its legs have short setae with a few longer hairs scattered on the tarsi and metatarsi. The setae on the carapace are extremely short. Live specimens have been observed inhabiting the crevices of volcanic rock. As a eumenophorine genus, Mascaraneus spiders are considered unusual for their lack of stridulatory organs.

  • Mascaraneus remotus* Gallon, 2005
    • Common name: N/A
    • Distribution: Mauritius

Monocentropus Pocock, 1897

Monocentropus lambertoni spider

Lamberton’s baboon spider, Monocentropus lambertoni, is a medium-sized tarantula native to Madagascar.

Monocentropus consists of two species of burrowing spiders known from Madagascar and Yemen. Monocentropus lambertoni is a medium-sized spider with a leg span of up to 5 inches. It is shades of light to medium brown with an abundance of lighter setae covering its body. The genus is differentiated from other genera in the Eumenophorinae subfamily by having only feathery setae instead of both spiky stridulatory setae and large feathery setae.

  • Monocentropus lambertoni Fage, 1922
    • Common name: Lamberton’s baboon spider, Malagasy Lamberton brown tarantula
    • Distribution: Madagascar
      • Researchers note that molecular phylogenetics and morphological characteristics suggest M. lambertoni is misplaced. It is currently regarded as incertae sedis, of uncertain placement, pending further studies.

Myostola Simon, 1903

Myostola is a monotypic genus. M. occidentalis is described as having a dark brown body and legs, with light, rose-colored setae on the joints of the legs and palps. It is a large burrowing spider with a total body length measuring around 2.4 inches.

Phoneyusa Karsch, 1884

Phoneyusa lesserti tarantula

Phoneyusa lesserti is a type of baboon spider found in Central Africa.

Little is known about the spiders in the genus Phoneyusa. The genus is typically placed within the Eumenophorinae subfamily, and its members are believed to be relatively large, heavy burrowing tarantulas. As noted above, Eumenophorinae tarantulas have spiky stridulatory setae between the coxae of leg I–IV and a spot of stiff setae on the femur of the pedipalps.

Pterinochilus Pocock, 1897

orange baboon tarantula on peanuts

The orange baboon spider, Pterinochilus murinus, is known for its aggressive temperament.

Tarantulas in the genus Pterinochilus are small to medium-sized baboon spiders, reaching a leg span of 4-6 inches. These spiders are typically hairy with a sunburst-patterned carapace and a patterned abdomen. They are known to be quick and defensive with powerful venom. Pterinochilus spiders inhabit a wide range of habitats across sub-Saharan Africa. Although they are terrestrial burrowing spiders, some species, such as P. murinus, exhibit semi-arboreal tendencies in captivity.

Satyrex

Tarantulas in the genus Satyrex have the longest known palps (leg-like appendages near the mouth) of all tarantula species. These appendages are believed to aid in reproduction and decrease the male’s risk of death by cannibalism. These spiders are known to be aggressive, but their venom is said to be relatively mild. The S. speciosis male specimen measures 1.06 inches in total length, while the female measures 1.19 inches. The male palp is 3.13 times the length of the carapace. Males are dark golden-brown and females are light golden brown. They construct deep, lightly-lined burrows in semi-arid shrublands. The total length of the male S. somalicus specimen measures 0.72 inches, while the male palp is 2.23 times the length of the carapace. The female of S. somalicus is unknown. It is a small, grey-brown tarantula that constructs its burrows under rocks in semi-arid shrublands.

Selenogyrus

Selenogyrus foordi tarantula

The tarantula species Selenogyrus foordi has a green and fawn-colored sunburst carapace.

Selenogyrus spiders are differentiated by the unique stridulating organs between their chelicerae. Recent research, including the 2024 description of Selenogyrus foordi, has expanded our knowledge of the genus, though many species remain poorly studied. The newly described S. foordi has a total length of just over 2 inches. Males are described as having a carapace with fine, soft, turquoise hairs and a sunburst pattern with alternating bands of dark green and fawn. Its legs and abdomen are light to dark brown and covered in long, light setae. Females are black with dense orange-red setae on their legs.

Stromatopelma

Stromatopelma tarantula

Tarantulas in the genus Stromatopelma are arboreal spiders native to West Africa.

Stromatopelma tarantulas are known for the woolly, bottlebrush-like setae on their legs and abdomen. These spiders are arboreal and build tube-like webs in lower elevation forest regions. They are described as defensive, skittish, and quick. Stromatopelma spiders have very potent venom with stromatoxin peptides, which can cause medically significant effects in humans. These spiders can reach a leg span of 5.5-7 inches.

Trichognathella

Trichognathella is a monotypic genus consisting only of Trichognathella schoenlandi. The genus was established because the hair on these tarantulas’ chelicerae is not feathery, unlike the spiders in Harpactira. This small burrowing tarantula is brownish-grey with a gold, sunburst patterned carapace and a patterned gold abdomen. The joints of its legs and palps are also gold. It has long, light-colored setae on its legs and abdomen.

  • Trichognathella schoenlandi* (Pocock, 1900)
    • Common name: N/A
    • Distribution: South Africa
