Abstract

Poore, G.C.B. (2023). New records and one new species of Callichiridae (Crustacea, Axiidea) from the Indo-West Pacific with keys to species of Corallianassa, Lepidophthalmus and Neocallichirus. Memoirs of Museum Victoria 82: 71–95. Collections of Callichiridae from surveys of coral reefs and sandy shallow environments in the Indo-West Pacific, particularly Papua New Guinea and Australia, have been used to redescribe and differentiate poorly known species and/or extend the range of others. Keys are provided for identification of the Indo-West Pacific species of Corallianassa Manning, 1987 (six species) and Lepidophthalmus Holmes, 1904 (four species). The distribution of Glypturus armatus (A. MilneEdwards, 1870) now includes Tonga, within its previously known geographic range. Supplementary descriptions and illustrations are provided for Michaelcallianassa indica Sakai, 2002, Mocallichirus mocambiquensis (Sakai, 2004) and Mucrollichirus mucronatus (Strahl, 1862). The 15 Indo-West Pacific and Australian species of the genus Neocallichirus Sakai, 1988 are diagnosed with a key for identification (N. variabilis (Edmondson, 1944) excepted). N. nagoi sp. nov. is described as a new species.
