Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 10 - 12; Raggi anali molli: 11 - 13. This species is distinguished by the following set of characters: simple nasal spines; almost straight uppermost preopercular spine with 2 small cusps dorsally and barbed posterior cusp; elongated first dorsal fin in males; lateral line reaching almost base of caudal fin; with ventral lateral cirrus (Ref. 83439).
