Parioglossus interruptus, a new species of goby from the Western Pacific

Abstract

A new species of goby, Parioglossus interruptus sp. nov. is described from specimens from Iriomote Island, Okinawa Prefecture, Japan. It is distinguished from congeneric species as follows: scales imbricate; anterior oculoscapular canal with pores C', D, E and F; preopercular canal with pores N' and O'; a single sensory papilla in the symphysial line; a narrow, black lateral band extending from the posterior edge of the eye through the upper part of the opercle and along the lower half of the trunk, fading gradually above the anal fin, not extending to caudal fin base; a black triangular to oblong blotch on the caudal fin, between 5th or 6th and 15th or 16th segmented rays, not extending onto fin base. A key to the species of Parioglossus is given
