Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); bellemansi: The species is named in dedication to the professional biologist and conservationist, collector, aquarist, and friend Marc Bellemans, Belgium (Ref. 97568).
Eponymy: Marc Bellemans (d: 1953) is a Belgian ecologist and ichthyologist and keen killifish aquarist. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 18 - 21; Anal spines: 0; Anal soft rays: 19 - 21; Vertebrae: 26. Diagnosis: Nothobranchius bellemansi can be distinguished from all other species of the genus Nothobranchius by the following unique combination of characters: 18-21 dorsal fin rays; 19-21 anal fin rays; 29-30 scales in longitudinal series; short pelvic fin, tip reaching anus; terminal portion of mouth on ventral profile pointed; males and females unpaired fins median portion with red spots (Ref. 97568).

The type locality comprised a pool in a clay depression containing a few centimeters of standing water in the savannah floodplains southeast of the Nuba mountains; these depressions become filled during the rainy season, with certain deeper parts retaining water for longer periods (Ref. 97568).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
