Polyacanthus is a genus of woodlice belonging to the family Armadillidae. This genus was described in 1909 by Gustav Budde-Lund. The type specimen for this species is a Polyacanthus aculeatus from Cabinda Province.[1] There are currently two species in this genus.[2]
The dorsal surface of this genus has characteristic long spines. Their frontal lamina protrude past the end of the head. Their epimera are very long, rectangular, and point outwards in a nearly horizontal direction. The first and second thoracic segment of this genus have rounded ventral lobes. Their second to seventh pereon segments have a broad triangular tooth directed forwards at the base of the external spines. Their telson is hour-glass-shaped with a long distal part and truncated apex. Their uropod protopodite is rectangular, and their exopodite is reduced.[3]
