 en A new flatfish of the Indo-Pacific genus Asterorhombus   check for this species in other resources (Pleuronectiformes:Bothidae)
Dannie A. Hensley and John E. Randall

Abstract

Five species of Asterorhombus   check for this species in other resources are currently recognized, A. bleekeri   check for this species in other resources , A. osculus   check for this species in other resources , A. annulatus   check for this species in other resources , A. intermedius   check for this species in other resources , and A. fijiensis   check for this species in other resources . A new species, Asterorhombus filifer   check for this species in other resources , is described from 19 specimens. It is easily separated from A. bleekeri, A. osculus, and A. annulatus by its palmate gill-rakers and its detached and longer first dorsal-fin ray. It is distinguished from A. fijiensis by less body depth, longer first dorsal-fin ray on the average, simpler membrane on this ray, narrower interorbital width, and both eyes usually with one tentacle (vs. 1-9 tentacles on upper eye only). Asterorhombus fijiensis and A. filifer are the only species of the genus with males having a wider interorbital than females. Asterorhombus filifer most closely resembles A. intermedius, which differs in having a longer first dorsal ray, smooth edge on the membrane of this ray, usually more lateral-line scales, and males with greater interorbital width. Asterorhombus filifer is the most wide-ranging species of the genus, extending from the western Indian Ocean to the Hawaiian and Society islands, and is the only species of Asterorhombus occurring on the Pacific Plate.
