A revision of the systematic position of Periclimenaeus spinimanus Bruce, 1969 (Crustacea: Decapoda: Pontoniinae) and the designation of Anisomenaeus gen. nov. * Author Bruce, A.

Periclimenaeus spinimanus Bruce, 1969: 165-167 . — 1978: 123–127 , figs 1–3. — Li, 2000: 136 , fig. 165. Type. holotype , male, USNM168529 . Type locality. Ras Afir , Somalia . Host. No data. Bathymetric range. 68–73 m . Distribution. Known from type locality only. Remarks. The presence of an anterior median dorsal lobe of the first abdominal tergite in Anisomenaeus is a feature that is also present in Periclimenaeus robustus Borradaile, 1915 , the type species of the genus Periclimenaeus , and seven other species of that genus: P. gorgonidarum (Balss) , P. uropodialis Barnard , P. palauensis Miyake & Fujino , P. ardeae Bruce , P. djiboutensis Bruce , P. lobiferus Bruce , P. orontes Bruce ; but is lacking in the 43 other Indo-West Pacific species of the genus. It has also not been reported in any other pontoniine genus. Anisomenaeus gen. nov. can be distinguished from other sponge associated pontoniine taxa by the following key. Genera of suspected but unproven association with sponges are given in parentheses.
