Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335); latebra: Named after the Latin word 'latebra' meaning 'delitescence' or 'seclusion' due to the fact that the species remained unrecognised for such a long time, and because confirming the locality information and occurrence was a challenge for more than 10 years; a noun in apposition (Ref. 116769).

背面の脊椎 (合計) : 0; 背鰭 (合計) : 14; 肛門の骨: 0; 臀鰭: 8; 脊つい: 34 - 36. Diagnosis: Labeo latebra differs from all other Labeo species from the Nile in having only 12-13 scales around the caudal peduncle, vs. 16 in L. meroensis, 16-18 in L. forskalii and L. coubie, 16-20 in L. horie, and 18-22 in L. niloticus; it further differs from all other Labeo in the main Nile River except L. meroensis in having only 4.5-5.5 scales between lateral line and mid-dorsal line, vs. 6.5-7.5 in L. forskalii and L. coubie, 6.5-8.5 in L. horie, and 8.5-9.5 in L. niloticus; from L. meroensis it differs in having 34-37 scales in lateral line, vs. 39-41 (Ref. 116769). Labeo latebra shares 12 caudal peduncle scales with L. parvus and L. lukulae from the Congo basin, L. chariensis and L. djourae from the Chad basin, L. ogunensis and L. brachypoma from Nilo-Sudanic river basins west of the Niger Delta, and the Upper Guinean endemic L. obscurus, which is confined to the Konkouré River (Ref. 116769). Labeo latebra differs from L. ogunensis by having 3.5-4 scales between lateral line and ventral fin insertion, vs. 4.5; from L. parvus, L. obscurus and L. brachypoma in a higher lateral line scale count of 34-37, vs. 30-33; and finally from L. djourae, L. lukulae and L. chariensis in the poorly developed snout which lacks a prominent suckermouth vs. prominently swollen snout with well-developed sucker, the poorly developed ethmoid furrow vs. very prominent ethmoid furrow, and the small nub-like tubercles on the snout vs. usually prominent, acanthoid snout tubercles (Ref. 116769).
Recovered on soft-bottomed in-shore habitats, in quite shallow water (Ref. 116769). Long intestines partly filled with small particles suggest that this species is browsing the upper sediment layers on the riverbed for Aufwuchs and organic material (Ref. 116769).
