Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 12693)
Has 10-11 branched dorsal rays, a large blackish blotch on the caudal peduncle; the caudal, dorsal, anal and pelvic fins with white distal margins and black subdistal margin; some specimens almost black in life (Ref. 27732). With well-developed papillae on each side of lower lip; large mental lobe and large ethmoid spine perpendicular to snout when viewed from above (Ref. 12693).
Inhabits areas of boulders and cobble of rapidly flowing stretches of large and medium-sized rivers. Feeds mainly on mollusks and occasionally on other benthic invertebrates.
