Notes

Identification to species level follows Armbruster (2008) based on the following characters: evertible cheek plates with> 10 hypertrophied odontodes; dentaries forming angle of <90°; deep body, not dorso-ventrally flattened; lips lacking fimbriae; villiform teeth of equal size in premaxilla and dentary; colour pattern of four irregular dorsal saddles (first and second are usually combined in small specimens); dorsal and caudal fins without orange margin (in life); head plates not outlined in black; dark bar between eyes, e-shaped dark blotch on the snout (broken in some specimens); and fins with dark and light bands of approximately equal width (irregular in some specimens).

An interesting observation is that our specimens exhibited variation in terms of the degree of abdomen plating and markings: adult specimens from collection points near the mouth of the river (sampling sites NH01, NH02 and NH12) showed complete abdominal plating and a vermiculated pattern (Fig. 22a, b); those from further up the river (sampling sites NH04, NH05 and NH08) lacked abdominal plating and associated colouration (Fig. 22c, d), with the exception of one individual that was partially plated with discrete spots (Fig. 22e, f). In light of this variation we were hesitant in referring all these individuals to Peckoltia vittata , and hence we use the "cf." qualifier. The three DNA barcodes we generated from the different phenotypes/sites, however, were identical.

Twenty-eight individuals were caught by hand from both woody substrates (sampling sites NH02, NH04, NH05, and NH08) and rocky substrates (sampling sites NH01 and NH12). Two further specimens of this species are reported from the collection of fishes at INPA.
