> Cyprinodontiformes (Rivulines, killifishes and live bearers) > Procatopodidae (African lampeyes) > Procatopodinae
Etymology: Hylopanchax: Greek, hylo, hyle = material, wood + Panchax, a word created by Meinken in 1932leki: The species name 'leki' is the Lingala word for the "smaller or younger sibling", referring to the fact that the species is the slightly smaller one of the sibling species Hylopanchax ndeko of the left bank of the Lokoro River (Ref. 94189).
Eponymy: The binomial is not an eponym but a word in the Lingala language for ‘smaller sibling’, referring to the fact that it is slightly smaller than a related species found in the same area. (Ref. 128868), visit book page.

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 11 - 13; Épines anales: 0; Rayons mous anaux: 18 - 20; Vertèbres: 30. Diagnosis: This species is distinguished from all other Hylopanchax species except for Hylopanchax ndeko, by the position of the dorsal fin (D/A = 8-10 vs. D/A = 11-14), the number of dorsal fin rays (11-13 vs. 6-9), the number of pectoral fin rays (11-13 vs. 8-10), the number of transversal scales (19-20 vs. 15-16), by its deep body (29.2-35.5% of standard length vs. 16.3-25.6% of standard length), by the low caudal peduncle ration (1.2-1.7 vs. 1.6-2.4), and by having 2 or 3 rows of scales underneath the eye versus 1 row of scales; it has also longer dorsal spines of vertebrae at mid-body versus short dorsal spines with lower length differences between mid-body and anterior or posterior spines (Ref. 94189). It is distinguished from Hylopanchax ndeko by having fewer scales in the longitudinal series (m21-23 vs. 24-26), prominent lobes of the supra-temporal neuromast system and male colour pattern; snout, lower jaw, and anterior part of throat dark orange versus yellow snout and lower jaw and white throat in H. ndeko; flanks just below dorsal fin with orange shine versus purple shine, dorsal and anal fin dark orange versus yellow anal and dorsal fin with a red distal submarginal stripe and a nearly transparent margin, white edged caudal fin olive brown with orange shine versus white edged blue caudal fin (Ref. 94189).
