pectoral-fin insertions; post-orbital length at least
60% of snout length; maxillary barbels very well developed,
about twice as long as head, reaching pelvic fins,
unbranched and without tubercles or distinct basal
membrane; mandibular barbels with long, simple and
slender ramifications: mandibular teeth poorly developed,
numbering 24-28 (28 in the holotype); denticulations
of pectoral fin spines distinctly weaker on outer

humeral process rather narrow, pointed and granulate,
very slightly keeled ventrally; adipose fin moderately
developed, very close/subcontiguous to rayed dorsal
