Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); skeltoni: The specific name is given in honour of Professor Paul Skelton, emeritus managing director of the South African Institute of Aquatic Biodiversity, for his dedication to the science of ichthyology, and in recognition of his vast contributions to the study and documentation of African freshwater fishes and biodiversity; a noun in genitive (Ref. 122068).
Eponymy: Professor Dr Paul Harvey Skelton (d: 1948) is a South African ichthyologist. [...] (Ref. 128868), visit book page.

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 15 - 17; Épines anales: 0; Rayons mous anaux: 15 - 17. Diagnosis: Nothobranchius skeltoni is distinguished from all other species of the genus by the following characters in males: body colouration light blue with grey to brown scale margins; anal fin grey to red-grey with irregular dark grey spots proximally, followed by a broad dark red to maroon medial band, a narrow light grey subdistal band, and a broad black distal band; caudal fin light grey with slender semi-translucent dark grey distal band; pelvic fins light blue-grey, with broad dark red to maroon medial band and narrow black distal margin (Ref. 122068). Furthermore, it differs from the other members of the Nothobranchius taeniopygus species group in central and western Tanzania by a body depth at pelvic-fin origin 26.3-30.0% of standard length vs. 30.3-37.6%; suborbital depth 15-22% of head length vs. 23-31%; caudal peduncle depth 11.8-12.9% of standard length vs. 12.9-16.8%; and caudal peduncle length 160-169% in its depth vs. 119-151% (Ref. 122068).
