Males: short hyoid barbel behind symphysis of lower jaw; small eyes, each without an aphakic space; relatively large olfactory organs; triangular shape of upper denticular plate, bearing a transverse series of 3 well-developed hooked denticles; crescent shaped lower denticular plate bearing transverse series of 4 strong, symmetrically placed denticles, fused at base; skin is naked, absence of dermal spinules. Larvae: short and deep; moderately inflated skin; short, digitiform hyoid barbel; moderate size of pectoral fins, not reaching base of dorsal and anal fins; pelvic fins absent (Ref. 086949).
