Gerald R. Allen: Cirrhilabrus brunneus, a new wrasse (Pisces: Labridae) from north-eastern Kalimantan, Indonesia, pp. 1-4

Abstract

Cirrhilabrus brunneus is described from a single male specimen, 43.6 mm SL, collected at north-eastern Kalimantan, Indonesia. It is one of only three species in the genus that possesses a lunate caudal fin. The new species, which is overall dark brown in colour, including the median and pelvic fins, closely resembles C. lunatus from the Ryukyu Islands, southern Japan, and the Ogasawara Islands. However, unlike the latter species, it lacks a broad orange-yellow zone along the sides at the level of the pectoral fins, a pale yellowish band along the base of the dorsal fin, and irregular diagonal red lines on the snout and the postorbital portion of the head that extends onto the anterodorsal part of the body. There is also a substantial difference in maximum size with males of C. lunatus attaining a maximum standard length of about 85 mm in comparison with less than 50 mm for C. brunneus.
