背棘 (總數) : 0; 背的軟條 (總數) : 7; 臀棘: 0; 臀鰭軟條: 8 - 10. Diagnosis: Amphilius crassus is diagnosed from A. jacksonii, A. ruziziensis, A. pedunculus and A. lujani by its shorter caudal peduncle, caudal peduncle length 13.3-15.5% of standard length vs. 16.0-20.9%, and from A. jacksonii, A. ruziziensis and A. lujani by its deeper caudal peduncle , caudal peduncle depth 10.1-12.0% of standard length vs. 4.8-9.5% (Ref. 103388). It is diagnosed from A. ruziziensis, A. pedunculus and A. frieli by its longer dorsal-fin insertion to adipose-fin insertion length, 42.2-44.6% of standard length vs. 37.5-41.7% (Ref. 103388). Amphilius crassus is further diagnosed from A. jacksonii by its deeper body, body depth at anus 14.5-17.4% of standard length vs. 9.6-13.2%, and from A. ruziziensis by wider interorbital width, 28.9-34.1% of head length vs. 23.4-25.1%, and deeper body, body depth at anus 14.5-17.4% of standard length vs. 11.1-12.9%; it is further diagnosed from A. lujani by having fewer branched pectoral-fin rays, 7-8, rarely 9 vs. 9, and from A. frieli by its fewer branchiostegal rays, 6-7, rarely 8 vs. 8-9, fewer branched pectoral-fin rays, 7-8, rarely 9 vs. 9-10, fewer gill rakers on the first gill arch, 6-8, rarely 9 vs. 10-11, rarely 9 or 12, and wider interorbital width, 28.9-34.1% of head length vs. 25.1-27.7% (Ref. 103388).
