🐟 Physical Description

Dorsal soft rays (total): 8 - 9; Anal soft rays: 6; Vertebrae: 32. Diagnosed from its congeners by the following characters: presence of premaxillary and dentary accessory teeth (vs. absence); shallower caudal peduncle (7.7-8.7% in SL vs. 9.0-10.8% in Rhinolekos britskii and 10.2-13.0% in Rhinolekos garavelloi); 18-20 mid-dorsal plates (vs. 21-24 in Rhinolekos britskii and 23-27 in Rhinolekos garavelloi).
