Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 22 - 24; Anal spines: 0; Anal soft rays: 28 - 29; Vertebrae: 44. Diagnosis: Marcusenius lucombesi can be distinguished from its congeners by the following characters: distance dorsal fin origin to end of caudal peduncle 40.0-43.2% of standard length; distance anal fin origin to end of caudal peduncle 43.6-45.9% of standard length; pre-anal length 56.6-59.2% of standard length; pre-dorsal length 59.5-63.3% of standard length; low caudal peduncle depth 25.0-30.8% into its length; circumpeduncular scales 14-16; anal fin rays 28-29; dorsal fin rays 22-24; total vertebrae 44; lateral line scales 55-56; anterior gill rakers (4-5)+(4-5); total anterior gill rakers 8-10; posterior gill rakers (6)+(7); total posterior gill rakers 13; jaws with 5-5 conical teeth (Ref. 95448).
Found in aquatic weed beds, marginal vegetation and root-stocks of bank vegetation in headwater streams through to floodplain margins (Ref. 95448).
