Ukuran / Berat / umur
Kematangan: Lm ? range ? - ? cm
Max length : 11.5 cm SL jantan/; (Ref. 11333); 16.5 cm SL (female)
duri punggung lunak (Keseluruhan (total)) : 24; Sirip dubur lunak: 39; vertebrata, bertulang belakang: 68. Two terminal bulbs separated by an interspace, 1.2-2.4 times the length of distal bulb. Barbel length mostly 31-71% SL in specimens less than 8 cm; 67-91% SL in larger ones. Terminal filaments short, 4-6 without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than others. Pigment in filament axes variably present or absent. Distal bulb spheroidal to ovoid, not much longer than wide, 1.5-4.3 times proximal-bulb length. Axis of stem usually lightly pigmented, between bulbs unpigmented or lightly pigmented; dark spot present or not at proximal end of distal bulb. External chevron-shaped or roundish striated areas on stem unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 9 (Ref. 11333).
Body shape (shape guide): elongated.
