Scanning Electron Microscopy and First Molecular Data of Two Species of (Copepoda: Lernaeidae) from (Cyprinidae) and (Clariidae) in Kenya.

A parasitological study carried out in May 2022 and March 2023 in the Nyando River of Lake Victoria Basin, Kenya, disclosed two parasitic lernaeid copepods: Humes, 1957, from the gills of a cyprinid, the Ningu Boulenger, 1901, endemic to the Lake Victoria drainage system, and Fryer, 1957, from a clariid, the North African catfish (Burchell, 1822). The copepods were studied and supplementary taxonomic information was presented using scanning electron micrographs and genetic data. Scanning electron microscopy (SEM) provided information on the morphology of 's antennae, oral region, thoracic legs (2-5), and furcal rami not previously reported.
