Abstract

A new species of dwarfgoby, Eviota occasa, lacking all head pores, is described from Palau and Japan. It has a dorsal/anal-fin formula of 8/8, some of the pectoral-fin rays are branched, the 5th pelvic-fin ray is absent or rudimentary, the 4th pelvic-fin ray has 5 branches, the first dorsal fin is crossed by two dark bands separated by a diagonal light band, and there is a distinct dark spot on the caudal peduncle anterior to the caudal fin, followed by a pale bar and then a yellow-orange broad wedge-shaped bar at the caudal-fin base.
