Etymology: Amphilius: Greek, amphi = on both sides + Greek, leios = fatlujani: Named for Nathan K. Lujan who collected the holotype and most paratypes of this species, and who has made excellent contributions to our knowledge of freshwater fishes (Ref. 103388).
Eponymy: Dr Nathan Keller Lujan (d: 1976) is an ichthyologist, taxonomist, ecologist and evolutionary biologist who is a postdoctoral researcher at the Canadian Department of Fisheries and Oceans, Toronto. [...] (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 7 - 8; Anale stekels: 0; Anale zachte stralen: 8 - 10. Diagnosis: Amphilius lujani is diagnosed from A. pedunculus, A. frieli and A. crassus by having a more slender caudal peduncle, its depth 8.1-9.5% of standard length vs. 9.9-12.3% (Ref. 103388). It is diagnosed from A. jacksonii by having a deeper caudal peduncle, its depth 8.1-9.5% of standard length vs. 4.8-7.9%, and a deeper body, body depth at anus 13.5-15.8% of standard length vs. 9.6-13.2%; it is diagnosed from A. ruziziensis by having a wider interorbital width, 28.3-31.7% of head length vs. 23.4-25.1%, and a deeper body, body depth at anus 13.5-15.8% of standard length vs. 11.1-12.9%; it is further diagnosed from A. frieli by having fewer gill rakers on the first gill arch, 6-8, rarely 5 or 9 vs. 10-11, rarely 9 or 12, and a longer caudal peduncle, its length 16.8-20.9% of standard length vs. 14.4-16.4%; it is further diagnosed from A. crassus by having more branched pectoral-fin rays, 9 vs. 7-8, rarely 9, and a longer caudal peduncle, its length 16.8-20.9% of standard length vs. 13.3-15.5% (Ref. 103388).
Body shape (shape guide): elongated.
