Deep-sea squat lobsters of the Munidopsis serricornis complex in the Indo-West Pacific with descriptions of six new species (Crustacea: Decapoda: Munidopsidae)
The deep-sea squat lobster, Munidopsis serricornis (Lovén, 1852), originally described from the north-eastern Atlantic, has long been considered near cosmopolitan with numerous reports also from the western Pacific and northern Indian Ocean. These Indo-West Pacific records are reviewed along with new material from seamounts throughout the region. Munidopsis serricornis sensu stricto is restricted to the Atlantic Ocean. Six new species are described from the Indo-West Pacific: M. alcocki sp. nov. from the central to western Indian Ocean; M. atlantis sp. nov., from the Southwest Indian Ridge; M. macphersoni sp. nov. from the Austral Islands, French Polynesia; M. spiridonovi sp. nov. from the western Indian Ocean; M. nias sp. nov. from southern Indonesia and the Nicobar Islands; and M. pyrochela sp. nov. from New Zealand, Australia and the Southwest Indian Ridge.
