Etymology: Hylopanchax: Greek, hylo, hyle = material, wood + Panchax, a word created by Meinken in 1932 ; ndeko: The species name 'ndeko' is the Lingala word for "sibling", referring to the fact that the species is closely related to Hylopanchax leki of the right bank of the Lokoro River (Ref. 94189).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical
Africa: Lokoro River in Salonga National Park (Mai Ndombe drainage) (Ref. 94189) and the Kangara River (Lukenie drainage) (Ref. 96960), in the middle Congo River basin in Democratic Republic of the Congo.

Morphology | Morphometrics
soft rays: 18 - 21;
Vertebrae: 30. Diagnosis: This species is distinguished from all other Hylopanchax species except for Hylopanchax leki by the position of the insertion of the dorsal fin (D/A = 8-11 vs. D/A = 11-14), the number of dorsal fin rays (12-14 vs. 6-9), the number of pectoral fin rays (12-13 vs. 8-10), the number of transversal scales (18-22 vs. 15-16), by its deep body (24.3-34.3% of standard length vs. 16.3-25.6% of standard length), by the low caudal peduncle ration (1.2-1.5 vs. 1.6-2.4), and by having 2 or 3 rows of scales underneath the eye versus 1 row of scales; it has 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). Its is distinguished from Hylopanchax leki by having more scales in the longitudinal line (24-26 vs. 21-23) and male colour pattern; snout and lower jaw yellow versus dark orange snout and lower jaw in H. leki; dorsal and anal fin yellow with red distal edges versus dark orange anal and dorsal fin (Ref. 94189).
Found in small shady streams and rivers (Ref. 94189).
