Morphologie | Morphométrie
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 10-14; Épines anales 0; Rayons mous anaux: 9 - 12; Vertèbres: 35 - 37. Diagnosis: Afronemacheilus abyssinicus is distinguished from its congener A. kaffa by having usually 8 or 9 branched dorsal-fin rays (vs. usually 7); the anterior and posterior nares closely spaced (vs. well separated); the intestine straight (vs. with a single small loop), no contact between sphenotic and epiotic (vs. usually in contact); two pairs of pharyngobranchials and usually three basibranchials (vs. three and four, respectively); the dark spots on flank small and irregular becoming larger and transversely extended on dorsum (Ref. 94278).
Found on the bottom of Lake Tana and in patches of macrophytes along the shore of the lake, and along the banks of the Blue Nile (Ref. 94278).
