Fig. 63

Diagnosis

The species is distinctive in having a characteristic pattern of the abdomen and body shape (both the carapace and the abdomen are very convex and the legs relatively short – Fig. 63A–B). The structure of the female genitalia is characteristic, with very short seminal ducts and large spermathecae.

Etymology

The specific name is Latin, meaning ‘globular’, referring to the shape of the carapace.
