Notes

Identification to species level follows Armbruster (2004), and Kner (1854) based on the following characters: three rows of lateral plates on the caudal peduncle; snout naked with fleshy tentacles lacking odontodes; 8-9 branched dorsal-fin rays (three individuals with nine rays and eight individuals with eight rays); and black colour with small white dots (apparent on body and fins in life, but only apparent on abdomen in preserved material).

We note that Ancistrus  , and particularly the Amazonian species, are a group in dire need of taxonomic revision.

Eleven individuals were caught by hand on both woody (sampling site NH04) and rocky substrates (sampling site NH01). The species appeared abundant throughout the river. An example of a live specimen is pictured in Fig. 14.
