Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 9 - 10; Raggi dorsali molli (totale) : 13 - 14; Raggi anali molli: 7 - 8. Differs from all members of the complex in having in the breeding male the horizontal lines restricted to a series of long dark dashes, and upper sides with a zone of light tan extending the length of the body. It differs from all other species by modally having 8 anal rays and 6 scales below the lateral line (Ref. 27671).
Body shape (shape guide): elongated.
Migratory behaviour is undetermined (Ref. 126106).
