Etymology: Akawaio: Named for Akawaio Amerindians that populate the region of the upper Mazaruni and to recognize their valuable help while studying the fishes of their lands. A masculine noun; penak: From the Akawaio name ‘penak’, which is apparently used unambiguously for this species. A masculine noun in apposition.
Eponymy: The Akawaio Amerindians who live in the region of the upper Mazaruni River, Guyana, were thanked for their valuable help while the describers studied the fishes of their territory. (Ref. 128868), visit book page.
