Research Abstract

A purpose of the present study is to be clear a species diversity of the bothid flounders in the Southern Hemisphere, based on about 3000 specimens of males and females, or young to senescence from the Coral Sea and from waters around Australia and New Zealand. The data analyzed by computer were used for taxonomical work with a consideration of growth and sexual dimorphism..
(1).The following 12 genera and 39 species were distributed in the waters ; 1 species of Taeniopsetta, 2 of Bothus, 1 of Crammatobothus, 1 of Crossorhombus, 1 of Laeops, 1 of Japonolaeops, 3 of Tosarhombus 10 of Engyprosopon, 3 of Psettina, 10 of Arnoglossus, 3 of Parabothus and 3 of Asterorhombus. Among them 14 species were undescribed, and 10 species were described as new species ; Engyprosopon bellonaensis, E.septempes, E.rostratum, E.Iongipterum, E.raoulensis, Tosarhombus longimanus, T.brevis, Parabothus filipes and Arnoglossus micrommatus. The remaining four species were submitted. Arnoglossus bleekeri and Psettina variegatus are first record since oniginal description. Taeniopsetta ocellata, Bothus myriaster, Crossorhombus kanekonis, Laceps kitaharae, Japonolaeops dentatus, Engyprosopon grandisquamus, E.xystrias, E.maldivensis, E.hureaui, Parabothus kiensis, P.coarctatus, Psettina iijimae, P.variegatus, Arnoglossus macrolophus and A.tenuis are first record from the Southern Hemisphere.
(2).The bothid flounders of the Southern Hemisphere are same to those of the Northern Hemisphere in generic level, but are distinguished by about 50% from Northern Hemisphere in species level. The barrier is not complete because they are dispersed by the floating larvae, though they are bottom fishes.
