The taxonomy of three species ofGirellafrom East Asian waters,G. punctataGray, 1835,G. leonina(Richardson, 1846) andG. mezinaJordan & Starks, 1907, is reviewed and intraspecific (individual and ontogenic) variations detailed.Girella mezinais characterized by a very wide mouth and thick upper lip, the soft-rayed portion of the anal fin high and round, dorsal profile of the head abruptly slanting in front of the eyes in adults, a transverse yellow band on the body in life, and 3–4 rows of teeth along the outer jaw margins, the central cusp of each tooth being wider than the lateral cusps in adults.Girella punctatais characterized by usually 2 rows of teeth along the outer jaw margins, usually 7 transverse series of scales between the lateral line and median spinous portion of the dorsal fin (TRac), and usually 52–55 pored lateral line scales (LLp). The species is variable in body and caudal fin shape, extent of squamation on the opercular region, and number and position of dark spots on the scales. It also exhibits ontogenetic variation in the number of tooth-rows.Girella leoninais characterized by a conspicuously black opercular flap, essentially a single row of teeth along the outer jaw margins, usually 10–11 TRac and usually 59–64 LLp. Intraspecific variations were evident in the mouth position, scale condition and body color after death, and in the number of pores of cephalic lateral line canals. The holotype ofG. punctata, previously known only from a figure, is described for the first time.Girella melanichthysis synonymized underG. punctatawith a lectotype designated for the former.
