| Abstract |
Luciobliviidae, a new family in the superfamily Gammaroidea (Amphipoda: Crustacea), is described on the basis of species in the genus Lucioblivio gen. nov. from subterranean waters of Japan. Mesogammaridae Bousfield, 1977 is rediagnosed; Octopupilla gen. nov. from subterranean waters of Japan is described and Eoniphargus (Uéno, 1955) from subterranean waters of Japan and Korea is included. The members of Lucioblivio, Octopupilla and Eoniphargus share several characters, including reduced eyes, a setose body, reduced coxae, feeble appendages and pedunculate coxal gills. To elucidate the phylogeny of the three genera among others, a sequence analysis of the 28S rRNA gene was conducted for 14 species in six families, including the three genera, from the superfamilies, Gammaroidea, Crangonyctoidea and Hadzioidea. The tree from a neighbour-joining analysis and the strict consensus tree from a maximum-parsimony analysis indicate monophyly of Mesogammaridae. Luciobliviidae is embedded within a clade of taxa belonging to the superfamily Gammaroidea. These results and the occurrence of gammarid-type calceoli in species of the new family indicate that Luciobliviidae should be placed within the superfamily Gammaroidea. |
