Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
This species is distinguished from its congeners by having the following combination of characters: abdomen entirely covered with small platelets imbedded in skin and irregularly scattered from pectoral girdle to pelvic-fin insertions (vs. abdomen totally naked or with 1-4 small platelets on each side just posterior to gill opening in P. parmula and P. nasuta ); it is distinguished further from P. parmula by having 51-71 premaxillary teeth (vs. 31-48), 24-28 lateral plates in the median series (vs. 28-31), longer snout length (62.1-70.0 vs. 53.8-63.0% HL); from P. nasuta by having a shorter snout length 62.1-70.0 (vs. 71.1-75.6% HL) and a larger orbital diameter 11.9-14.8 (vs. 8.6-11.3% HL) (Ref. 84022).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); The area where most of the specimens were collected is a shallow creek (0.2-0.5 m depth and approximately 5 m wide) with rocky bottom, swift current, and clear water; most of the creek banks are deforested and covered with grasses. Other fish species collected syntopically were Trichomycterus sp., Geophagus brasiliensis, Neoplecostomus sp., and Astyanax sp. (Ref. 84021).
