背面の脊椎 (合計) : 0; 背鰭 (合計) : 27 - 32; 肛門の骨: 0; 臀鰭: 21 - 25; 脊つい: 38 - 39. Diagnosis: Cyphomyrus lufirae is distinguished from all its congeners, C. aelsbroecki, C. cubangoensis, C. discorhynchus, C. macrops, C. psittacus and C. wilverthi, by a larger caudal peduncle depth, 6.8-8.4% of standard length vs. smaller, 5.3%, 6.1-6.7%, 5.7-7.0%, 5.2%, 5.8% and 6.2% respectively, and a higher number of circumpeduncular scales, 14-16, rarely 12-13 vs. exclusively 12 in all congeners except for C. discorhynchus, which rarely also possesses 13 circumpeduncular scales (Ref. 122874). In addition, C. lufirae differs from C. macrops, C. psittacus and C. wilverthi by a lower number of dorsal fin rays, 27-32 vs. higher, 36-37, 33-41 and 38-40 respectively; and from C. aelsbroecki, C. cubangoensis and C. discorhynchus by a longer prepelvic distance, 41.0-43.8% of standard length vs. shorter, 39.7%, 38.9-39.1% and 37.0-41.0% respectively (Ref. 122874).

Found in river sections with moderate current, he depth of the water was variable, between 50 cm and 10 m (Ref. 122874). This species is highly appreciated by the local inhabitants of the Lufira River due to the high fat content of its meat; they prefer to eat it smoked (Ref. 122874).
