Abstract

A new species, Chromis oligactis from the coast of Khanh Hoa province (Vietnam, South China Sea) has been described, which is characterized by a moderately deep body (contained 2.2 times in the standard length), fin formula D XIV, 10; A II, 10; P i, 15–16; three spiniform procurrent rays of the caudal fin, 26 gill-rakers in the outer row on the first arch, and 19 perforated scales in the anterior lateral line. The holotype of the new species was caught at shallow depths, which is not typical for Indo-Pacific species of Chromis with 14 spinous rays in the dorsal fin.
