Harpactira baviana • 3/4″


Harpactira baviana (Hanover olive starburst baboon), captive bred, endemic to South Africa. A medium-size Harpactira with a bluish tint on the legs. Recommended for advanced beginners and above.



Harpactira baviana is one of several Harpactira endemic to The Republic of South Africa. The species was described from 2 males and 5 females collected from two local farms in the vicinity of Hanover, located roughly in the middle of South Africa. Hanover lies in a semi-desert region called the Great Karoo. The Karoo sits on the Great Escarpment, a plateau occupying most of South Africa. As a result, Hanover lies in a high desert region, 4,868 ft above sea level.

Purcell found male H. baviana in October, females in October, November, and January. Females in January had young, of which 90 were collected.

Vegetation in the Karoo is sparse. Purcell mentions finding specimens “under stones, generally in shallow excavations, but sometimes also in burrows a few inches deep.” Immature specimens were common, adults “rarely met with” [1].

Karoo winter months are the warmest (avg. max. 86F/30C) and the wettest (13.9 inches/353.0 mm yearly).

H. baviana spiderlings are hardy, easy to keep. Bluish tint on distal legs is most noticeable in immature specimens, such that one customer mistook a spiderling for H. pulchripes. Per Purcell, H. baviana resembles H. namaquensis [1].

Females mature at about 3 1/2″. Males mature about 30% smaller.
