Descripción breve Claves de identificación | Morfología | Morfometría

This species is distinguished from its congeners by the following characters: with branch of the temporal sensory canal at sphenotic, which gives rise to the supraorbital canal, with two pores; upper tooth plate of branchial arch with three series of teeth; the area at the corner of the mouth, ventral to the maxillary barbel, with a small, triangular fleshy flap, which may variably present a small prolongation at its posterior tip, forming a short barbel-like structure; with a conspicuous dark brown or black patch transversally crossing the orbit, forming a mask-like blotch; absence of a distinct color pattern along midline of flank; with dorsolateral body plates only with small, irregular, rounded or vertically elongated dark brown or black blotches; ground color of plates typically light yellow or beige; absence of a relatively large, conspicuous dark patch on anterior portion of dorsal fin; with dorso- and ventrolateral body plates with pale yellow or beige background coloration, with dark blotches on flanks conspicuously standing out from the ground color of plates; with a conspicuous mask-like blotch; with ossified portion of hypobranchial 2 ranging from moderately developed, with size similar to cartilaginous portion, to well developed, around twice size of cartilaginous portion, even in smaller specimens with up to about 4.2 cm SL (Ref. 138496).
Body shape (shape guide): short and / or deep; Cross section: oval.

Biología     Glosario (por ej. epibenthic)

This species was collected in streams with black, muddy, and mixed waters, all tributaries of the Ríos Itaya and Nanay. The sampled environments are first-order streams, with constant fluctuations in water level influenced mainly by local rainfall. These aquatic environments with width ranging from 4 to 8.1 m, depth ranging from 0.6 to 1.3 m. On the average, physicochemical parameters of the type-locality are the following: water temperature 26.2°C, pH 6.3, dissolved oxygen 2.4 mg/l, electrical conductivity of 30.5 µS/cm, and total suspended solids 15.0 mg/l. For other sampled localities, the average parameters were: water temperature between 24.5°C and 27.0°C, pH between 5.4 and 5.5, dissolved oxygen between 3.8 and 5.4 mg/l, electrical conductivity between 17.0 and 28.0 µS/cm, and total suspended solids between 8.0 and 14.0 mg/l. The substrate was mostly composed by sand, with some decomposing plant material. In most sampled streams,This species was observed in syntopy with C. sychri and C. ambiacus (Ref. 138496).
