Two new Pseudancistrus from Xingu and Teles Pires
 

Two new species of Pseudancistrus (Siluriformes, Loricariidae) from the Amazon basin, northern Brazil

Gabriel S. C. Silva, Fábio F. Roxo, Claudio Oliveira

Two new species of Pseudancistrus, a genus diagnosed by non-evertible cheek plates and hypertrophied odontodes along the snout margin, are described from two drainages of the Brazilian Shield: P. kayabi from
the rio Teles Pires (rio Tapajós basin) and P. asurini from the rio Xingu. The new species are distinguished from congeners (P. barbatus, P. corantijniensis, P. depressus, P. nigrescens, P. reus, and P. zawadzkii) by the
coloration pattern. Pseudancistrus kayabi has dark bars on the dorsal and caudal fins which are similar to that of P. reus from the CaronÃ* River, Venezuela. Pseudancistrus asurini is unique among Pseudancistrus in
having whitish tips of the dorsal and caudal fins in juveniles to medium-sized adults.
