摘要

Gnathia masca sp. nov. is described from material collected off Coconut Beach, Lizard Island, Great Barrier Reef, Australia. Males are characterised by a cephalosome with a shallow dorsal sulcus that stretches half its length, a slightly produced frontal border with two conical superior fronto-lateral processes and a conical inferior medio-frontal process. Male mandibles have 6 processes on the dentate blade and a distinct internal lobe with 6 or 7 crenulations and a single large distal process. Livemales, females and larvae are characterized by brown pigmentation especially in the male where it forms a dark band that stretches between the eyes, giving it the appearance of a mask.
