Etymology: Citharinops: Latin, cithara = lire like instrument + Greek, ops = appearance (Ref. 45335).
Environment / Climate / Range
Freshwater; demersal; potamodromous (Ref. 51243). Tropical, preferred ?
Africa: Chad, Bénué, Niger and Volta basins (Ref. 81281). Previously, 2 subspecies were recognized: Citharinops distichodoides distichodoides in Chad and Bénué basins (Ref. 2938, 81281), and Citharinops distichodoides thomasi in Niger and Volta basins (Ref. 2938, 7095, 81281).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 54 - ? cm
Max length : 84.0 cm SL male/unsexed; (Ref. 2938); max. published weight: 4.6 kg (Ref. 3799)
Morphology | Morphometrics
soft rays: 20 - 23. Diagnosis: more elongate than Cithardium and Citharinus species; body depth 2.2-2.7x and head length 3-3.7x SL; caudal peduncle 0.7-1.1x long than deep; head 1.6-2.0x long than wide; short snout, 1.0-1.7x of eye diameter; pectoral fins almost half of head length; adipose fin 0.3-0.7x its distance to dorsal fin; caudal fin with symmetrical lobes (tips becoming round in adults); cycloid scales; scale formula 7.5-9.5/50-56/10.5-12.5; 7.5-9.5 scales between lateral line and dorsal fin origin; 16-19 dorsal fin branched rays; 20-23 anal fin branched rays (Ref. 2938, 81281).
Monospecific, distinguished from other genus of family by the body form which is more elongated than 2 other genus: Citharidium and Citharinus (Ref. 2938).

Bayesian length-weight: a=0.01585 (0.00617 - 0.04070), b=2.96 (2.74 - 3.18), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
