摘要

A new argentinid species, Glossanodon microcephalus, is described based on 30 specimens (53-97 mm SL) from Tosa Bay, off Kochi Prefecture, Shikoku Island, southern Japan, and from the southwest South China Sea. The new species clearly differs from its congeners in having the following combination of characters: dorsal-fin rays 11-12; anal-fin rays 10-12; pectoral-fin rays 17-19; pelvic-fin rays 10-12; branchiostegal rays 5; gill-rakers on first arch 27-30; vertebrae 44-46; small conical teeth in 1-2 and 1-3 irregular rows on vomer and palatines respectively; 10-21 small conical teeth on lower jaws, and 3-7 on tip of tongue; head length 25-27% SL; snout length 30-33% HL; anus immediately anterior to anal-fin origin; a longitudinal black stripe above lateral line interrupted, alternately composed of short bars and faint blotches; dense pigmentation just behind chin; no melanophore on isthmus to abdomen; maturation at small size (the minimum sizes of mature males and females are 65 mm SL and 72 mm SL respectively). The new species is a benthopelagic dweller on muddy and sandy bottoms in depths of about 100-200 m.
