Predorsal cycloid scales 10-13; ctenoid on trunk. Body dusky brown with red spots; 4 blue spots on operculum; black line running from eye along sensory pore path to pectoral base; 2 dusky blotches on pectoral base, the uppermost spreading onto fin rays; large inverted `U'-shaped blotch on the cheek. In male, appressed anal fin occasionally reaching caudal fin, appressed dorsal reaching or overlapping caudal fin. Appressed anal and dorsal fins of female ending 2-3 and 1-2 scales, respectively, of caudal fin.
