توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 1; خارهاي باله مخرجي 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions (Ref. 57223). Post-orbital length at least 60% of snout length (Ref. 57223, 81251). Interorbital distance at most 86.6% of snout length; entire margin of opercle smooth (Ref. 81251). 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 (Ref. 57223, 81251). Mandibular teeth moderately developed (Ref. 57223), movable (Ref. 81251), numbering 20-27 (20 in the holotype)(Ref. 57223, 81251). Pectoral spines strongly serrated, with twice as many along anterior edge as posterior edge (Ref. 81251), denticulations finer and more dense on outer than on inner margin (Ref. 57223). Dorsal-fin spine smooth anteriorly (Ref. 57223, 81251), except for some apical denticles (Ref. 57223), few distal serrations on posterior edge (Ref. 81251). Humeral process about twice as long as deep, granulose, pointed and distinctly keeled ventrally (Ref. 57223, 81251). Adipose fin moderately developed and distinctly separated from rayed dorsal fin (Ref. 57223). Adipose-fin base long (Ref. 57223), 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 (Ref. 81251). Dorsal part of body and adipose spotted (Ref. 57223, 81251). Caudal fin spotted and without single dark patch at base of each fin lobe (Ref. 81251).
Maximum TL was recorded at 13.8 cm (Ref. 57223). Oviparous (Ref. 205).
