Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 9 - 10; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 8 - 10; Σπόνδυλοι: 28. Distinguished from the other species of the genus by the following combination of characters: 2nd dorsal fin rays modally I/9; anal fin rays modally I/8; scales in longitudinal series 29-31. Anal fin origin inserted below third branched ray of second dorsal fin. Trunk usually with five or six middle series of blackish brown blotches. One (sometimes split into two) conspicuous brownish black blotch on posterior part of nape; blotch larger and darker in female than in male. Cheek and opercle with many irregularly short blackish brown lines and vermiculations in adult. Second dorsal and caudal fins with about four to five rows of blackish brown spots.
