Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); krysanovi: The species is named in honour of Prof. Eugeny Y. Krysanov, a scientist at the Russian Academy of Sciences, who carried out cytological studies on Nothobranchius species, as well as the effects of radiation on their chromosomes in the Chernobyl area; the species name is pronounced 'kree-sa-nofi' (Ref. 85866).

خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 15-17; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 15 - 17. Diagnosis: Nothobranchius krysanovi is distinguished from other species of the genus Nothobranchius by the following combination of characters: males with bright colouration consisting of alternating light blue and orange-red oblique bars on body, dorsal and anal fins, and orange-brown caudal fin with orange subterminal and black terminal band; female with faint brown oblique bars on posterior part of flanks (Ref. 85866). It can be distinguished from the other species of the subgenus Nothobranchius as follows: from N. furzeri by male colouration, higher number of dorsal fin rays, 15-17 vs. 14-15; from N. kadleci by male colouration and shape of the frontal region, higher number of dorsal and anal fin rays, 15-17 vs. 13-14 and 15-17 vs. 13-14; and from N. orthonotus by male and female colouration, and lower number of scales on the mid-longitudinal series, 27-29 vs. 28-33 (Ref. 85866). Nothobranchius krysanovi can also be distinguished from N. rachovii by its higher number of diploid chromosomes, 2n=18 vs. 2n=16; and from N. pienaari by its much lower diploid chromosome number, 2n=18 vs. 2n=34 (Ref. 85866).
Found in ephemeral pools and swamps on floodplains; water level in the habitats is subject to seasonal changes and generally the water disappears completely during the dry season (Ref. 85866). Grass vegetation is usually found near the habitat margins; much of the swamps may be utilised by local inhabitants for the cultivation of rice; aquatic vegetation may comprise Nymphea, Ottelia, Lagarosiphon and Utricularia species (Ref. 85866). It has an annual mode of reproduction (Ref. 85866).
