Two of these species, Prionospiocristaventralis sp. n. and P.parapari sp. n., are new to science, whereas P.caspersi Laubier, 1962, P.fallax Söderström, 1920, and P.ehlersi Fauvel, 1928 have been previously recorded. Prionospiocristaventralis sp. n. is characterized by having ventral crests present on chaetigers XI-XIX, dorsal crests and low crests on chaetigers X-XXXIV, triangular neuropodial postchaetal lamellae with pointed ventral edges on chaetiger II, oval neuropodial lamellae on chaetiger III, digitiform pinnules on the posterior face of the first and fourth pairs, and branchial pairs II a
