Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 0; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 4 - 5; Σπόνδυλοι: 41. Diagnosed from its congeners by having diminutive eyes, posterior naris absent, presence of a triangular skin flap at mouth corner, dorsal and ventral fin fold deep and extending forward on the head to a vertical through tip of pectoral fin. Differs from Pygidianops magoi by
the presence of six laterosensory pores on head, presence of pectoral and anal fins, presence of 12-13 caudal fin rays associated with the caudal plate (Ref. 56682).
Body shape (shape guide): elongated.
