New killifish named Nothobranchius kadleci


Czech ichthyologist Martin Reichard has described a new species of African annual killifish from central Mozambique.

Naming the new species Nothobranchius kadleci in honour of killifish breeder Jaroslav Kadlec, Reichard published the description in a recent issue of the journal Zootaxa.  

Nothobranchius kadleci is similar to Nothobranchius furzeri from which it is distinguished by coloration (red pelvic fins, red lips, more extensive red coloration on body) and morphology (larger distance between pectoral and pelvic fins, shorter anal and dorsal fins, and shorter base of the anal fin).

Nothobranchius kadleci occurs sympatrically with Nothobranchius orthonotus and Nothobranchius rachovii, from which it can clearly be distinguished by different colour patterns of the fins and body, head shape and morphometric characteristics (depth of dorsal fin, distance between pectoral and pelvic fins, preanal distance, distance between pelvic and anal fins, depth of anal fin, length of caudal peduncle, body depth, and eye diameter).

The fish were found in small temporary pools, with a maximum depth of 10–100 cm, very turbid water and soft muddy bottom. Conductivity ranged from 68–300 uS/cm and water temperature during collection was 28–38°C.
