Remarks Males with hypertrophied odontodes on the sides of head, especially on the opercular area, and on the dorsal surface of branched pectoral-fin rays. Pectoral spine (or leading unbranched pectoral ray) is hypertrophied and the anterodorsal odontodes are markedly enlarged. Males have cusps of premaxillary teeth with smooth rounded edges, whereas females have sharper, less rounded cusps (Ref. 54478).

Diagnosis

Distinguished from all other species in the genus by the following combination of characters: anterior abdomen covered by plates, except for the area corresponding to the pectoral girdle, which usually lacks plates, when present in this region, plates are relatively small and few; posterior abdomen with a well-developed preanal plate, bordered anteriorly by a series of 3-5 usually polygonal plates; premaxillary and dentary teeth with unequal-sized cusps; uppermost caudal ray not prolonged in a filament; and snout tip with an oval naked area not reaching the last pore of the infraorbital sensory canal (Ref. 54478).
