| Family: |
Cyprinidae (Minnows or carps), subfamily: Smiliogastrinae |
| Max. size: |
8.9 cm SL (male/unsexed) |
| Environment: |
benthopelagic; freshwater |
| Distribution: |
Africa: Nile River, Volta basin (Ref. 2801, 2940), Lake Albert (Ref. 2801), Benué River (Ref. 2801, 2940, 81282), Chad and Niger basin (Ref. 2940, 81282). Reports from Lake Edward system (Ref. 2801, 4903, 47905) are misidentifications for Enteromius alberti or E. cf. mimus (Ref. 127947). |
| Diagnosis: |
Dorsal spines (total): 0-0; Dorsal soft rays (total): 11-11; Anal spines: 0-0; Anal soft rays: 8-8. Diagnosis: last simple dorsal-fin ray smooth on hind margin; scale formula 4.5-5.5/27-32/4.5; 2.5 scales between lateral line and pelvic-fin base; 12-14 scales around caudal peduncle; 7-8 branched dorsal fin rays; two pairs of barbels; anterior barbell not reaching to anterior margin of eye/not extending beyond centre of eye; posterior barbel reaching to, or extending beyond, posterior half of eye; lateral line complete and deeply depressed below dorsal fin; 4-6 short and widely spaced gill rakers on lower limb of first gill arch; maximum reported size 89 mm SL; 3 small, independent, round spots on sides; 2nd spot located slightly behind vertical line from last simple dorsal-fin ray; average distance centres 2nd-3rd spot/distance centres 1st-2nd spot (= RDT) is over 1.4 (Ref. 2940, 81282).
Description: medium-sized species; mouth subinferior; D: III,8; A: III,5; P:14-15; V: I,7 (Ref. 2940, 81282).
Coloration: basic color pattern consisting of 3 small spots aligned along middle of sides; 1st slightly before level of dorsal-fin origin, 2nd behind vertical line from last dorsal-fin ray; 3rd at end of caudal peduncle; this color pattern is characteristic for typical West African form of this species; additional spots may appear between 3 basic spots on mid-lateral line (lepidus form) and there may exceptionally be a series of numerous dots (larvae form) (Ref. 2940, 81282). |
| Biology: |
Three forms exist: West African typical form, Lepidus form with supplementary spots between 3 typical spots and larvae form with numerous aligned points (Ref. 2940). |
| IUCN Red List Status: |
Least Concern (LC); Date assessed: 20 March 2020 Ref. (130435)
