Abstract
A new species, Cirripectes kuwamurai is described based on a single specimen from Shirahama, Japan.Other three species of the genus, C.variolosus (Valenciennes), C.castaneus (Valenciennes) and C.polyzona (Bleeker) from Japan are redescribed. Cirripectes kuwarnurai differs from C.auritus Carlson in its color pattern and by the presence of a notch between spinous and soft portions of dorsal fin.Other characters shared by these two species suggest that they are each others' relatives and form a species group within Cirripectes.
