Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 7 - 8; Spine anali: 0; Raggi anali molli: 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).
