ຄີກົ້ນຂອງປາ: 18 - 23; ສັດທີ່ມີກະດູກສັນຫຼັງ: 32 - 33. This species is distinguished from all its congeners by the presence of a round flap of skin between contralateral pelvic-fins bases (vs. absence); differs further except P. nanus, P. pygmaeus, P. varii by the not having infraorbitals; differs from P. britzi, P. nanus, P. pygmaeus, P. varii by having fewer premaxillary teeth (14-19 vs. 20-29), from P. conwayi, P. marupiara, P. phasma by having more maxillary teeth (30-38 vs. 13-29); presence of two postcleithra; with five branched pelvic-fin rays; absence of adipose fin (Ref. 138024).
Body shape (shape guide): elongated; Cross section: compressed.
Collected from a small, shallow (less than 1 meter deep), slow-flowing terrafirme dark water streams, its channel width less than 15 meters at its widest point. At the time of sampling, water temperature was 25.6°C, conductivity 34 µS/cm, pH 5.3, and dissolved oxygen 2.03 mg/l. The substrate of the sampled section was composed mainly by silt and clay, with some leaf litter, and logs; all specimens were collected at the marginal vegetation (Ref. 138024).
