Etymology: aguaruna: Named after the Awajun people, better known by the name Aguaruna, is the second largest native population in the Peruvian Amazon. This Jivaroanspeaking culture also occupies a portion of the Río Morona basin, at the Departamento Loreto, Peru, where most of the known localities of the new species are located.
Eponymy: The Awajun people, better known by the name Aguaruna, the second-largest native population in the Peruvian Amazon, occupy a portion of the Río Morona basin (Departamento Loreto, Peru), where these fish occur. (Ref. 128868), visit book page.

背棘 (总数) : 2; 背的软条 (总数) : 8 - 9; 臀棘: 4; 臀鳍软条: 20 - 23. This species of the Holopristis ocellifer species-group (sensu Lima & Sousa, 2009) is distinguished by the following characters: two humeral blotches and a caudal peduncle blotch. In that group: the second humeral blotch larger and considerably darker than the first humeral blotch (vs. first humeral blotch larger and considerably more conspicuous than the second humeral blotch, which is vertically elongated and narrow), except H. yinyang to which it differs by the presence of a caudal peduncle blotch (vs. caudal peduncle blotch absent).
Cross section: oval.
This species was collected exclusively in solid ground forest streams, both the streams tributaries of Río Morona (e.g., quebrada Uchpayacu, quebrada Katmaentsa, and quebrada Monshurbac), as well as the quebrada Platanoyacu (tributary of Río Corrientes) and streams near Leticia where the species was recorded are blackwater streams. For a stream near Leticia from where the species was found and observed, the Caño Pichuna has pH 6.83, conductivity 18 μS/cm, and temperatrure (at 12:50 p.m.) of 26.5°C. Recorded food items include larvae of aquatic Diptera, Hymenoptera (presumably ants), Homoptera, Ephemeroptera, aquatic Coleoptera, and larvae of terrestrial Diptera (Phoridae). Reported fecundity of 136 oocytes for mature females were collected in November (Ref. 109742).
