Size / Vikt / Age
Maturity: Lm ? range ? - ? cm
Max length : 15.6 cm SL hane/ej könsbestämd; (Ref. 11333); 18.8 cm SL (female)
Mjukstrålar i ryggfenan (totalt) : 23 - 25; Mjukstrålar i analfenan: 35 - 37. A single terminal bulb, three times longer than wide (Ref. 37473); 1.1-2.3% SL, with a single, digitate terminal projection 12-90% of bulb length. Bulb and projection combined 1.9-3% SL. Barbel 40-78% SL mostly more than 30%. Axis of stem moderately to darkly pigmented. External chevron-shaped or roundish striated areas unpigmented, closely spaced or contiguous distally. A few tiny spheres outside axis proximal to bulb in some specimens; otherwise no spherical or granular inclusions in stem. Middorsal paired spots between occiput and dorsal-fin origin usually 8, sometimes 9 (Ref. 11333).
