Etymology: Rhinolekos: Name from the Greek 'rhinos' for nose, nostril and 'lekos' for plate, referring to presence of the lateronasal plate; britskii: Named for Heraldo A. Britski, Museu de Zoologia da Universidade de São Paulo, in recognition of
his dedication and remarkable contributions to the studies in Hypoptopomatinae and to Neotropical Ichthyology, in general.
Eponymy: Dr Heraldo Antonio Britski is a Brazilian ichthyologist who was awarded a bachelor’s degree (1960) and a doctorate (1973) by Universidade de São Paulo where he is still a researcher, even though he is officially retired. [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8 - 9; Anal soft rays: 6; Vertebrae: 31. Distinguished from its congeners by the following characters: presence of transverse dark bands on pectoral-,pelvic- and anal-fin rays (vs. absence); 31 vertebrae (vs. 32), and by anterior portion of the compound supraneural-first dorsal-fin proximal radial contacting the neural spine of the 9th vertebra (vs. 10th). Differs from Rhinolekos garavelloi by the larger post-anal length (34.7-37.7% in SL vs. 29.0-34.6%); smaller thoracic length (14.7-18.0% in SL vs. 18.1-20.8%); and fewer plates in the dorsal series (24-28 vs. 30-35). Can be diagnosed from Rhinoleko schaeferi by the absence of premaxillary and dentary accessory teeth (vs. presence); and 21-24 mid-dorsal plates (vs. 18-20) (Ref. 86681).
