Reproductive behavior of epinepheline ser-ranids is known from only a few studies describing group or pair-spawning in members of the genera Epinephelus, Plectropomus and Variola (see reviews in Thresher, 1984; Shapiro, 1987). Reproductive behavior of members of the genus Cephalopholis has yet to be described. Groupers of this genus range in size from 10-40cm SL and inhabit trop-ical reefs at depths of 1-200m. There are 19 recognized and three undescribed species distri-buted in the Indo-Pacific (Randall, 1987). Nzioka (1979) reported seasonality of spawning of Cephalopholis off East Africa; Smith (1966) described hy-bridization between Cephalopholis fulva and Par-anthias furcifer in the Caribbean. Cephalopholis boenack (Bloch) is a relatively small (to 250mm SL) grouper distributed in the western Pacific and Indian Oceans where it usually occurs on dead reefs in protected waters (Randall, 1987). Pair spawning of this species was ob-served on the evening of 15 November, 1986 at Horseshoe Reef, part of the Papuan Barrier Reef system, off Bootless Inlet, Papua New Guinea. This is the first known report of reproductive behavior in this genus. The details are given herein.
