簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 8 - 9; 臀鰭軟條: 4 - 6; 脊椎骨: 32. Distinguished from its congeners by the following characters: shorter post-anal length (29.0-
34.6% in SL vs. 34.7-37.7% in Rhinolekos britskii and 35.7-41.3% in Rhinolekos schaeferi); longer thoracic length (18.1-20.8% in SL vs. 14.7-18.0% in Rhinolekos britskii and 13.7-17.6% in Rhinolekos schaeferi); 30-35 dorsal plates (vs. 24-28 in Rhinolekos britskii and 26-28 in Rhinolekos schaeferi). Can be further diagnosed from Rhinolekos britskii by the absence of transverse dark bands in pectoral-, pelvic and anal-fin rays (vs. presence); by having 32 vertebrae (vs. 31), and anterior portion of the compound supraneural-first dorsal-fin proximal radial contacting the neural spine of the 10th vertebra (vs. 9th); and from Rhinolekos schaeferi by having 23-27 mid-dorsal plates (vs. 18-20); 24-28 mid-ventral plates (vs. 20-22); higher caudal peduncle (10.3-13.0% in SL vs. 7.7-8.7); wider head (24.6-28.1% in SL vs. 20.5-23.9%); and absence of premaxillary and dentary accessory teeth (vs. presence) (Ref. 86681).
