Elongate body covered with diminutive elongated cycloid scales, except for cephalic region. Identified by following combination of characteristics: short blunt snout (3.3%-4.4% of SL), slightly subterminal mouth, maxilla ending behind orbital margin. Moderate eye size, its length approximating that of snout (3.3%-4.3% SL). Five to four gill rakers on lover limb. Head length 17.9%-19.5% SL, with straight dorsal profile or in males strong crest, in straight line over preopercular region. Strong supraopercular spine covered by dermal fold. Pectoral fins shorter than head (57.5%-70% HL), round in shape, its coloration intense yellow, and in some cases, black. Distal margin of dorsal and anal fin black; that of anal fin wider. Predorsal fin length 24.7% to 27.4% in SL and its origin on middle part of pectoral fin. Yellow body coloration, some brown regions. Ventral part slightly lighter that dorsal one. Base of dorsal fin black along its entire length, becoming fainter near caudal fin. Three rows of dark spots on sides, upper one continuous, remaining ones interrupted and blurred. Body covered with cycloid and elongate scales, having basket-shaped pattern.</paragraph>
