🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 1; Anal spines: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions . Post-orbital length at least 60% of snout length . Interorbital distance at most 86.6% of snout length; entire margin of opercle smooth . Maxillary barbels longer than head, unbranched, without tubercles and bordered by a short but distinct black basal membrane; outer mandibular barbels with few short, simple and rather thin ramifications, branches of inner mandibular barbels also simple, short and few, but thicker and sometimes tuberculate . Mandibular teeth moderately developed , movable , numbering 20-27 (20 in the holotype) . Pectoral spines strongly serrated, with twice as many along anterior edge as posterior edge , denticulations finer and more dense on outer than on inner margin . Dorsal-fin spine smooth anteriorly , except for some apical denticles , few distal serrations on posterior edge . Humeral process about twice as long as deep, granulose, pointed and distinctly keeled ventrally . Adipose fin moderately developed and distinctly separated from rayed dorsal fin . Adipose-fin base long , its length 4.2-11.3 times the distance between rayed dorsal- and adipose fin and 2.5 to 3.5 times longer than deep . Dorsal part of body and adipose spotted .
