Mazarunia charadrica López-Fernández, Taphorn B. & Liverpool 2012

Distinguished from all congeners, among other characters, by approximately equal uncinate process and anterior arm and reduced anteroventral expansion of epibranchial 1 (vs. uncinate process narrower and complete anteroventral expansion in the other two species), a dorso-ventrally flattened maxillary process of the palatine (vs. cylindrical in the other two species), cycloid (vs. ctenoid) scales in the opercular, postorbital, lateral chest and anal-genital regions, the absence of a mid-lateral spot, and a diffuse dark area covering the dorsal portion of the head giving the impression of a 'black cap'. Possessess a unique juvenile pattern of seven vertical dark bars partially preserved in adults. Bars 3-6 in antero-caudal direction are most visible in juveniles and medium-sized specimens but become fainter and almost disappear in adults. Many specimens show only bar number 3 (midlateral bar) (Ref. 91746).

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 8; Analspines: 3; Analsoft rays: 7 - 8; Vertebrae: 26

Abundant in the entire upper Mazaruni River basin, and especially in tributaries with rocky substrates and rich in rapids. Collected from black water sites with fairly high transparency (0.55-1.0 m Secchi depth), none to relatively fast currents (0-0.6 m/s), temperature (21.7- 24.5°C), pH (4.4-4.8), dissolved oxygen (5.2- 9.3 mg/L) and very low conductivity (
