Diagnosis.

Chimarra sassandrae has a general similarity to C. intexta , especially in the general attributes of the structure of tergum X and the inferior appendages. It can be diagnosed by details in both structures. The short, weakly sclerotized dorsal part of the lateral lobe of tergum X lies flatter and does not curve downward, and its apical projections are more acute. The inferior appendages have the dorsal projection even more strongly mesally curved and ventromesal tooth or cusp is more prominent and acute apically. This gives the inferior appendage, in lateral view, a distinctly more subquadrate appearance and this provides the most readily discernable diagnostic difference for the two species. Additionally, the anteroventral margin of segment IX is less produced than in C. intexta and the shape of the phallic spines is different.

Distribution.

Cameroon, Ghana, Guinea, Ivory Coast, Mali, Togo.
