Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 16 - 18; Espinhos anais: 0; Raios anais moles: 16 - 19. Diagnosis: Nothobranchius itigiensis belongs to the N. ugandensis species group presenting the following combination of characters in males: body colouration light blue with red to red-brown scale margins; frontal part of head red-brown and throat light blue or red; caudal fin uniform red; anal-fin base light blue or yellow with red-brown spotted pattern (Ref. 123150). Nothobranchius itigiensis differs from all other members of the N. ugandensis species group by an anal fin yellow with red-brown spots proximally, that are merged medially to a pattern parallel to fin rays and may be fused distally to form a slender marginal band; caudal peduncle length 14.9-15.7% of standard length vs. 16.1-23.8%, and 96-103% of its depth vs. 111-157%; and head width 68-72% of its depth vs. 73-83% (Ref. 123150).

The type locality is an ephemeral pool formed in the marshy terrain drained by the Mlumbi and Kisigo streams; an extensive pool of about 50 m wide; the water was turbid, the bottom of the pool not visible (Ref. 123150).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [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).

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

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