Abstract
The Indo-Pacific labrid fish Paracheilinus rennyae is described from four male specimens, 52.2-60.4 mm SL, collected in 15-21 m depth off southwestern Flores Island in the Lesser Sunda island chain of Indonesia. It is distinguished from most congeners by the lack of filamentous extensions of the dorsal fin rays in males and a rounded caudal fin margin, a combination of features shared only by P. octotaenia (Red Sea). It differs from the Red Sea species in having 13-14 rakers (vs. 16-18) on the first gill arch and several colour pattern differences. Genetic analysis (CO1) indicates it is closely related to P. angulatus from the Philippines and northern Borneo (Brunei, Sabah, and Kalimantan), but the two species exhibit marked differences in the shape of the median fins.
