Conchaspis capensis is similar to C. tsaratananae Mamet by having multilocular pores on abdominal segment 3 and by having tubular ducts. Conchaspis capensis differs by having multiloculars in clusters of 2 or 3 pores (only 1 pore on each side of each segment on C. tsaratananae) and by having tubular ducts on metathorax (absent on C. tsaratananae).
