Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); attenboroughi: The specific name is given in honour of Sir David F. Attenborough, in recognition of his dedicated efforts to promote biophilia: raising awareness of the wonders and beauties of nature for so many people worldwide, promoting awareness of the importance of biodiversity conservation, and above all, inspiring so many researchers in the field of natural history, including the authors; a noun in genitive case (Ref. 123150).
Eponymy: Sir David Frederick Attenborough (d: 1926) is famous as a maker of wildlife television programmes. [...] (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 14 - 17; Spine anali: 0; Raggi anali molli: 16 - 17. Diagnosis: Nothobranchius attenboroughi belongs to the N. ugandensis species group presenting the following combination of characters in males: body colouration light blue with red or red-brown scale margins; frontal part of head red-brown, throat light blue or red; caudal fin uniform red; and anal fin light blue or yellow with red-brown spotted pattern (Ref. 123150). Nothobranchius attenboroughi differs from all other members of the N. ugandensis species group by a light blue anal fin with red-brown dots proximally and medially; becoming yellow distally with red-brown narrow stripes parallel to fin rays; and caudal peduncle length 122-129% of its depth vs. 96-121% or 130-157% (Ref. 123150). Furthermore, it differs from N. moameensis, by a smaller body depth, 25.7-31.0% of standard length vs. 31.6-33.2%; a smaller head depth, 80.1-86.2% of head length vs. 87.1-94.3%; and a dorsal fin that is positioned posterior to anal fin, preanal length mean 59.8% of standard length and predorsal length mean 60.6% of standard length vs. anteriorly positioned with mean values of 62.2% and 60.9% respectively, in N. moameensis (Ref. 123150).
The distribution area of Nothobranchius attenboroughi overlaps with those of N. sagittae and N. serengetiensis, but syntopic occurrences are rare (Ref. 123150). Found in isolated temporary pools in a seasonal stream system; in turbid water, the bottom of the pool, less than a meter at the deepest point, not visible (Ref. 123150).
