Size / Weight / umur
Maturity: Lm ? range ? - ? cm
Max length : 14.6 cm SL jantan/; (Ref. 57223)
Duri punggung (Keseluruhan (total)) : 1; duri punggung lunak (Keseluruhan (total)) : 7; Duri dubur: 0; Sirip dubur lunak: 13. Diagnosis: eyes remarkably large, 26.3% of head length, only comparable with some Synodontis species from the Congo River basin (Ref. 82238). Gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels broadly fringed, shorter than head, unbranched and not tuberculate, but with a distinct basal membrane; mandibular barbels with simple and more or less thick ramifications, especially those of the inner pair; width of premaxillary tooth plate comprised at most 1.8 times in eye diameter; mandibular teeth numbering 19; pectoral-fin spines of holotype broken off, but in the basal region, denticulations are stronger on inner than on outer margin; dorsal-fin spine also mutilated, but remaining basal stump smooth anteriorly; humeral process granulate, concave on upper margin, not keeled ventrally; adipose fin rather long, low and distinctly separated from the rayed dorsal fin; outer margin of caudal fin black-edged (Ref. 57223).
Coloration: only known specimen (holotype) light, outer caudal-fin lobes are dark-edged (Ref. 57223).
Oviparous (Ref. 205). Maximum total length 202mm (Ref. 57223).
