Diagnosis

Upper pectoral fin rays entire. Nape with as many as 30 dark spots. A prominent diagonal, black line from posterior part of upper jaw to operculum. 4 broad, dark bands on abdomen; 2nd dorsal fin with 3-4 rows of black spots; pectoral fin clear, base with 2 small dusky spots. Predorsal cycloid scales 7-9, trunk ctenoid. In male, anal fin when appressed reaching almost the caudal fin; appressed 2nd dorsal fin overlapping caudal.
