Collins; Event: eventDate: 2013-11; Record Level: institutionCode: INPA; basisOfRecord: PreservedSpecimen  Notes Identification to species level follows Armbruster (2004), Rapp Py-Daniel (1985)and La Monte (1929)based on the following characters: lateral plates with well-developed keels; hypertrophied odontodes present along snout margin; three rows of lateral plates on the caudal peduncle; large interorbital distance; pronounced medial ridge on snout; head plates with sinuous rows of odontodes; interopercular plate with between 15 and 20 strong and distally hooked odontodes; pectoral spine roughly same length as head, with long odontodes; and spots on body roughly same size as those on head. Nine individuals were caught by hand from woody substrates (sampling sites NH04 and NH08). In addition to the main river stem, the species was also observed in lake and igarapehabitats, and appeared abundant. It was not found in association with rocks. An example of a live specimen is pictured in Fig. 16. 2013-11 INPA Valeria Nogueira Machado; Emanuell Duarte Ribeiro; Rupert A.
