Abstract:
A new species of argentinid fish, Glossanodon macrocephalus Bineesh Endo, from the Arabian Sea, off the southwestern coast of India, is described on the basis of four specimens (129-164 mm SL). The new species clearly differs from its congeners in the following combination of characters: dorsal-fin rays 10-11; pectoral-fin rays 21-23; anal-fin rays 12-13; pelvic-fin rays 11-12; branchiostegal rays 5; gill rakers on first arch 30-36; vertebrae 47-48; a patch of small conical teeth on middle of lower jaws; predorsal 49-51% SL; prepectoral 36-39% SL; prepelvic 57-58% SL; distance from pelvic to anal-fin origin 26-28% SL; head length 35-39% SL; eye diameter 22-26% HL; snout length 28-30% HL; location of anus immediately anterior to anal-fin origin; broad longitudinal black stripe above lateral line; dark spot on the base to half of pectoral fin; and no teeth on tongue. The new species is a benthopelagic dweller on muddy bottoms in depths of around 300-600 m.
