Panthea   acronyctoides species-group

The P. acronyctoides   species-group contains a single species pair, P. acronyctoides   and P. virginarius   , with P. acronyctoides   populations arranged into two subspecies. The male is characterized by the bulbous vesica armed with a pair of unequal-sized cornuti, the female by the globular or oval single chambered corpus bursae and a short wide ductus, about 2 × as long as wide. Both species have populations with a strongly contrasting black and white pattern, very similar in external appearance to each other and to the Palaearctic species P. coenobita (Esper)   , but not found in any other North American species. The P. acronytoides   group appears to be most closely related to the P. furcilla   group. DNA cox -1barcode sequence data shows little differentiation within or between the two groups (Anweiler unpubl. data).
