Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 14.6 cm SL macho/indeterminado; (Ref. 11333); 15.6 cm SL (female)
Raios dorsais moles (total) : 25; Raios anais moles: 38; Vértebras: 67. Two terminal bulbs separated by a long interspace, 1.3-2.5 times the length of distal bulb. Barbel length 43-50% SL. Four long filaments, arising together from distal end of distal bulb or from a short stem; all with numerous conspicuous bulblets of variable size. Distal bulb 0.9-1.6 times length of proximal-bulb. Axis of stem lightly, often sporadically pigmented; axis between bulbs and in filament lightly or unpigmented. Suggestion of spot at base of distal bulb in one specimen. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).
