| Abstract: | Twenty-one specimens of an ergasilid were collected from the gills of the sharptooth catfish, Clarias gariepinus (Burchell), from the Eastern Cape, South Africa. The first leg and antennae morphology conformed to the genus Neoergasilus Yin, 1956. While the invasive Neoergasilus japonicus (Harada, 1930) is the only Neoergasilus species that has been reported from Africa, the combination of several characteristics, separates the Eastern Cape specimens from N. japonicus and the other eight Neoergasilus congeners. These include an inflated cephalothorax; the presence of an oval dorsal ornamentation anterior to the cephalosome; a spine on the posterodistal margin of the first antennal segment; a cone-like process at the proximal margin of the second antennal segment; a knob-like process on the inner distal margin of the first exopodal segment of leg 1 and two forked spines on the third exopodal segment; leg 4 bearing a 2-segmented exopod and 3-segmented endopod; a single-segmented fifth leg with a seta extending from the base of the pedigerous somite and three unequal setae on its free segment; and a median caudal rami seta with an array of spines. Supporting genetic data were generated using two partial ribosomal RNA genes, 18S and 28S, and one partial mitochondrial DNA gene, COI. The Eastern Cape species is here proposed as new to science and described as Neoergasilus africanusn. sp. (Ergasilidae: Cyclopoida). This is the first Neoergasilus species described from the sharptooth catfish and from the southern hemisphere. Additionally, a key to all the species of this genus is provided.
