Nothobranchiidae (African rivulines)
Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); kadleci: The species is named in honour of the late Jaroslav Kadlec (1951-2006) from Brno, Czech republic, a renowned killifish breeder recognized worldwide for his articles on killifish breeding, ecology, and his photographs; to be pronounced 'khadlatsi' (Ref. 83370).
Eponymy: Jaroslav Kadlec (1951–2006) from Brno, Czech Republic, was a renowned aquarist, recognised worldwide for his articles on the ecology and breeding of killifish. (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 13 - 14; Anale stekels: 0; Anale zachte stralen: 13 - 16. Diagnosis: Nothobranchius kadleci is distinguished from N. furzeri by the smaller depth of the dorsal fin, 17.9-31.0% of standard length vs. 27.4-37.7% in males, 14.9-17.6% of standard length vs. 19.0-21.9% in females; smaller depth of the anal fin, 17.4-25.8% of standard length vs. 22.4-32.4% in males, 17.3-19.2% of standard length vs.19.3-24.5% in females; larger preanal distance, 64.0-65.8% of standard length vs. 58.9-61.3%, in females; presence of red colour on gill membrane and lips and red pectoral fins vs. no red colour on gill membrane and lips and typically yellow pectoral fins in N. furzeri; absence of black marginal band on caudal fin, present in some male N. furzeri; and a higher amount of red on caudal and dorsal fins and on body in males (Ref. 83370). It is distinguished from sympatric N. orthonotus, including putative N. kuhntae and N. mayeri, by the shape of the frontal region, convex in N. kadleci vs. flat in N. orthonotus; the presence of red pectoral fins with white margins, often with a bluish tint, vs. N. orthonotus with transparent or whitish pectoral fins with red margins; red background colour on the head covered with small to large light blue marking, vs. N. orthonotus with red spots on white to grey background colour of the head and, in most populations, also on anterior ventral part of the body; shorter preanal distance, 58.4-61.2% of standard length vs. 62.7-72.5%; and distance between pelvic and anal fins, 10.2-13.5% of standard length vs. 13.4-16.6%, in males (Ref. 83370). This species also differs from sympatric N. rachovii in males by lack of black margin of the caudal fin; distance between pectoral and pelvic fins, 15.1-21.7% of standard length vs. 12.8-16.7%; minimal body depth 15.0-16.9% of standard length vs. 13.5-15.4%; eye diameter 22.1-27.3% of head length vs. 26.0-32.6%; in females by preanal distance, 64.0-65.8% of standard length vs. 61.8-64.5%; length of caudal peduncle, 20.1-21.6% of standard length vs. 13.4-20.1%; depth of dorsal fin, 14.9-17.6% of standard length vs. 16.8-23.2%; and depth of anal fin, 17.3-19.2% of standard length vs. 21.0-23.2% (Ref. 83370).
The altitude of collection sites ranged from 24-82 m above sea level (Ref. 83370). It is found in small temporary pools varying from 3.5-2150 m², with a maximum depth of 100 cm, very turbid water and soft muddy bottom; littoral vegetation was present in the pools, sometimes with scarce Nymphaea vegetation (Ref. 83370).
