📖 Overview

This species was collected from the upper stretch of the Muyovozi River, above the Nyaganza (I and II) Falls (a left bank affluent of the uM basin) and these localities were characterised by a moderately weak water flow, sandy substrate, sometimes mixed with gravel; and grass banks with or without Phragmites (Poaceae). Of the three localities sampled, specimens were collected in medium to large schools (ca. 50 and 130 specimens). Also, both the other sympatric species of the Enteromius lineomaculatus species complex (E. lineomaculatus or E. quadrilineatus, are absent from the upper stretch of this affluent .
