Morphology | Morphometrics
This species is distinguished from all its congeners, except from P. bahiensis, P. cesarpintoi, P. jumbo, P. nandae, P. spilosoma, by having its abdomen covered by few small and dispersed platelets (vs. abdomen entirely covered by large plates in adult individuals or lacking plates in that region); differs from P. bahiensis, P. jumbo by having the pectoral girdle laterally exposed and supporting odontodes, except for a small area over symphysis (vs. lateral portion of pectoral girdle entirely covered by odontodes in P. bahiensis and pectoral girdle covered by thick skin medially and exposed only laterally supporting odontodes in P. jumbo); differs from P. cesarpintoi by the absence of irregular golden lines on head and body (vs. presence of irregular golden lines vermiform on head and body); differs from P. nandae by the presence of lower lip not elongated, falling distinctly short of pectoral girdle (vs. elongated posteriorly, reaching to or surpassing the anterior margin of cleithrumin); differs from P. spilosoma by the larger number of premaxillary and dentary teeth 20-26 and 19-23, respectively (vs. 9-16 and 8-16, respectively), by the presence caudal peduncle ellipsoid in cross-section (vs. flat in cross-section) and by colour pattern, dark body without lighter dots (vs. dark body with lighter dots); differs from P. cearensis mainly by the presence of completely exposed coracoid (vs. exposed only on the sides) and by having the abdomen covered by few small and dispersed platelets (vs. abdomen almost naked with a single row of elongate reduced plates on each side and a group of small, rounded plates irregularly distributed in the preanal region) (Ref. 124638).
This species Is generally found in fastflowing rivers with clean water, rock-and-gravel bottoms and a sandy substrate. The marginal vegetation is mainly dense shrubs and sparse trees. It was collected in association with other loricariid species: Hypostomus pusarum, Rhamdia quelen, Astyanax bimaculatus, Astyanax fasciatus, Compsura heterura, Characidium bimaculatum, Crenicichla brasiliensis, Hoplias
malabaricus, Leporinus piau, Poecilia reticulata, Serrapinnus piaba, Steindachnerina notonota, and Triportheus signatus (Ref. 124638).
