| Abstract | The uristid genus Ichnopus is revised and Glycerina included in its synonymy. A key is provided to the world species. Ichnopus pelagicus Schellenberg, I. pseudoserricrus Ledoyer, I. serricrus Walker, I. spinicornis Boeck, I. taurus Costa, (type species), I. tenuicornis (Haswell), I. teretis (Andres) and I. woodmasoni (Giles) are redescribed. The new species I. annasona, I. capricornus, I. caritus, I. comorensis, I. cribensis, I. malpatun, I. parriwi and I. wardi are described. Ichnopus nossibeensis Ledoyer is considered to be a synonym of I. pelagicus. Ichnopus macrobetomma Stebbing is considered to be an unrecognisable species. Two species groups are recognised: the I. spinicornis group, in which the ischium and carpus of gnathopod 1 are long and most species are pelagic, probably micropredators; and the I. taurus group, in which the ischium and carpus of gnathopod 1 are very long and most species are demersal scavengers. Ichnopus is considered to be .. a tropical to warm temperate Indo-Pacific genus with some remnants in the Mediterranean and the eastern North Atlantic Ocean. The most primitive species in both groups are found in the Mediterranean Sea and the eastern North Atlantic. It appears that the modern genus had its origins in the old Tethyan fauna. LOWRY, J.K. & H.E. STODDART, 1992. A revision of the genus Ichnopus (Crustacea: Amphipoda: Lysianassoidea: Uristidae). Records of the Australian Museum 44(2): 185-245. 185 Ichnopus is a poorly known genus of uristid lysianassoids which was established by Costa (1853) for I. taurus from the Mediterranean Sea. Since then 13 species have been described, five of which ·are currently considered to be synonyms. Most of these species have been reported in the literature only once or twice. The exceptions are I. taurus Costa, 1853, and I. spinicornis Boeck, 1861, both of which have been recorded frequently, either from the Mediterranean or the eastern North Atlantic.. Little is known about the biology, phylogeny or zoogeography of these animals. In this paper we redefine the genus, recognise two informal species groups, discuss the habitat preferences of species in· each group and discu9s the general zoogeographical distribution of the genus. We redescribe eight species and describe eight new species. The genus Glycerina Haswell, 1882, is synonymised with Ichnopus Costa, j1853, and I. nossibeensis Ledoyer, 1986, is synonymised with I. pelagicus Schellenberg, 1926. Ichnopus macrobetomma Stebbing, 1917 is considered to be an .unrecognisable species. The following abbreviations are used in the text: |
