Etymology: Barboides: Latin, barbus = barbel + Greek, oides = similar to (Ref. 45335); britzi: The species is named after Ralf Britz, at the Natural History Museum of London (BMNH), whose contagious enthusiasm for ichthyology and interest in tiny fishes has left a lasting impression on both authors (Ref. 57421).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 9; Anal spines: 0; Anal soft rays: 9; Vertebrae: 32 - 34. Diagnosis: Barboides britzi differs from B. gracilis in having a larger head, 26.1-30.0% of standard length vs. 22.4-26.7%; smaller eye, eye diameter 31.2-37.5% of head length vs. 39.1-44.4%; slightly longer caudal peduncle, its length 27.0-29.6% of standard length vs. 24.7-28.2%; a narrow ventromedian row of melanophores between pelvic fins and tips of cleithra vs. a wide ventromedian scattering of melanophores between pelvic fins and tips of cleithra; absence of scattered melanophores on the flanks vs. presence of scattered melanophores on the flanks; iris silvery vs. iris darkly pigmented; 1 hypural element above the 2nd hypural vs. 2 separate hypural elements above the 2nd hypural; and a yellow body colouration in life vs. an orange/red body colouration in life (Ref. 57421).
Found in Lokoli swamp forest, which is flooded throughout the year, with annual fluctuation less than 1 m (Ref. 57421). Water parameters fluctuate depending on rainfall with water temperature distincly lower than in other water bodies of the region due to the dense shadow of the forest; water dark brown in colour (Ref. 57421).
