Collins; Event: eventDate: 2013-11; Record Level: institutionCode: INPA; basisOfRecord: PreservedSpecimen  Notes Identification to species level follows Shibatta and Pavanelli (2005), Mees (1974)and Eigenmann (1912)based on the following characters: lower jaw not projecting beyond upper jaw; head large and rounded in dorsal view; head and body with numerous small papillae; insertion of pelvic fin though vertical of posterior base of dorsal; short caudal peduncle; rounded caudal fin; post-cleithral process short, not reaching vertical through dorsal fin origin; axillary pore absent; lateral-line canal terminating on caudal peduncle; premaxillary dentigerous plates with lateral margins posteriorly prolonged; colour brown, with dark mottled appearance; and caudal fin with dark dots irregularly distributed. An important inconsistency should be noted regarding the caudal fin shape. Eigenmann (1912)described the caudal fin of B. villosusas being "notched", but figured a specimen with a rounded caudal fin ( Mees 1974). The photograph of the holotype (FMNH 53219) on the All Species Catfish Inventory Web page (http://acsi.acnatsci.org/base/image_list.html?mode=genus&genus=Pseudopimelodus) shows a fish lacking most of the caudal fin. The specimens we collected had a rounded caudal fin. Four individuals were caught by hand from their lodgements in woody substrates at the margin of the main river (sampling site NH04). An example of a live specimen is pictured in Fig. 32. 2013-11 INPA Valeria Nogueira Machado; Emanuell Duarte Ribeiro; Rupert A.
