| Diagnosis |
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). Can be further distinguished from Rhinolekos britskii by having transverse dark bands in pectoral-, pelvic- and anal-fin rays absent, (vs. present) 32 vertebrae (vs. 31), and anterior portion of the compound supraneuralfirst dorsal-fin proximal radial contacting the neural spine of the 10th vertebra (vs. 9th); and from Rhinolekos garavelloi by having 26-28 dorsal plates (vs. 30-35); 20-22 mid-ventral plates (vs. 24-28); larger postanal length (35.7-41.3% in SL vs. 29.0-34.6%); shorter thoracic length (13.7-17.6% in SL vs. 18.1-20.8%); and slender head, width 20.5-22.9% in SL (vs. 24.6-28.1%) (Ref. 86681). Description: Dorsal-fin rays ii,6-7; anal-fin rays i,5; pectoral-fin rays i,6; pelvic-fin rays i,5 (Ref. 86681). |
