Abstract

A new species of blenny,Atrosalarias hosokawai is described on the basis of 15 specimens from the western Pacific. It is distinguished from the only known congeneric species,A. fuscus (=A. fuscus fuscus+A. fuscus holomelas), by the following: supraorbital cirrus broad and flat (vs. slender and thread-like inA. fuscus); dorsal fin broadly contacting caudal fin (vs. narrow contact); anal fin narrowly contacting caudal fin (vs. usually free or (rarely) very narrow contact); posteriormost dorsal and anal fin rays long (vs. short); first or posteriormost soft dorsal fin ray shortest (vs. posteriormost ray shortest); first soft anal fin ray shortest (vs. posteriormost ray shortest); caudal fin rays branched in specimens over 36.0 mm SL (vs. unbranched); a large dark spot on base of pectoral fin absent (vs. present or absent); a red margin on anterior dorsal fin absent (vs. present). Futhermore,A. hosokawai differs fromA. f. fuscus in having a lower number of dorsal fin spines (ten vs. eleven) and geographical distribution (western Pacific Ocean vs. Indian Ocean and Red Sea). AlthoughA. hosokawai occurs sympatrically withA. f. holomelas, it can be further distinguished from the latter in lacking a large dark spot on base of pectoral fin.
