توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 2; شعاع نرم باله پشتي (کل) : 6; شعاع نرم باله مخرجي: 8 - 9; مهره ها: 33 - 34. This species is distinguished from all its congeners by the following: gas bladder simple (vs. with secondary bladder) and dorsal and caudal fins uniformly dusky (vs. with distinct marks composed of dark blotch or broad band on the central part of the dorsal fin and pair of dark broad stripes on caudal fin, one central to each lobe) (Ref. 122376).
Cross section: oval.
This species is common in rapids where it hides among rocks and cavities in bedrock. It is also found in lentic habitats such as small floodplain lakes closely associated with main channel. This species occurs in syntopy with Platydoras cf. armatulus in the Xingu. Gut contents include variable amounts of detritus, sand grains, Trichoptera (caddisfly) larvae (including cases), a few small snails (ingested whole) and minute bivalves ca. 0.5 mm long (presumably corresponding to an early settling stage). The gut of one juvenile (ANSP 200070, 66.5 mm SL) was filled with Trichoptera larvae, including intact cases of Helicopsychidae (0.9–1.9 mm diameter), found in the stomach (n=3) and intestine (n=15), and two 4–5 mm larvae with cases of Odontoceridae (Marilia sp.) in the stomach as well as remnants of conspecific larvae/cases in the intestine (Ref. 122376).
