Munidopsis kareenae, a new species of seamount squat lobster from New Zealand with a key to the New Zealand species of Munidopsis (Crustacea: Decapoda: Munidopsidae)

Abstract

A new species of the squat lobster genus Munidopsis is described from Nukuhou Seamount, North Island, New Zealand. The new species is allied to members of the “Galathodes group” within Munidopsis that share a flattened, distally trifid rostrum, an unarmed carapace surface (apart from paired epigastric spines in some species), unarmed abdominal tergites and absence of pereopodal epipods. The new species is readily separated from these species by the combination of unarmed lateral carapace margins posterior to the anterolateral spine, absence of epigastric spines, and prominently spinose extensor margins of the pereopod 2–4 meri. Fourteen species of Munidopsis are now recorded from New Zealand; a key to the New Zealand species is provided.
