Max length : 9.3 cm SL mâle / non sexé; (Ref. 11333)
Rayons mous dorsaux (Total) : 24; Rayons mous anaux: 38; Vertèbres: 66. Two terminal bulbs separated by a long interspace, 2-3 times length of distal bulb. Barbel length increasing with size from 43-60% SL. Relatively long filaments 4, arising together from distal end of distal bulb or from a short stem, with long inclusions as well as rounded bulblets. Distal bulb equal in length to proximal-bulb. Axis of stem with some pigment, but light or unpigmented before proximal bulb; between bulbs pigment noticeably darker at base of distal bulb, forming a spot or small cap. External chevron-shaped or roundish striated areas pigmented or not. Middorsal paired spots between occiput and dorsal-fin origin 8 or 9 (Ref. 11333).
Body shape (shape guide): elongated.
