🐟 Physical Description

Dorsal soft rays (total): 8; Anal soft rays: 6. Diagnosed from all congeners, except Hisonotus insperatus, by having a pair of rostral plates at tip of snout. Distinguished from Hisonotus insperatus by having more teeth on premaxillary (12-30) and dentary bones (9-26) vs. (3-14) and (5-11). Can be differentiated from other species of the genus by the following combination of characters: longitudinal series with 25-26 plates; lateral line almost complete with 23-24 perforated plus last non-perforated plates; abdomen in adults entirely covered with large plates, five to eight plates in lateral series between tip of cleithrum and base of pelvic fin; large dark brown lateral stripe extending from tip of snout to caudal blotch; dorsum with basal dark blotch near origin of dorsal-fin region and three transverse dark brown bars located at end of dorsal-fin base, middle and end of caudal peduncle; yellow line extending from anterior part of each orbit, over inferior nostrils, both converging to tip of snout . : elongated.
