Gyrodactylus malalai sp. nov. (Monogenea, Gyrodactylidae) from Nile tilapia, Oreochromis niloticus (L.) and Redbelly tilapia, Tilapia zillii (Gervais) (Teleostei, Cichlidae) in the Lake Turkana, Kenya

sp. nov. is described from the fin surface of cichlid fishes (L.) and (Gervais) caught in Lake Turkana (Kenya). The new species morphologically resembles Paperna, 1973, but can be readily distinguished by the shape of the marginal hook sickles and the size of its hamuli. The sequence data of rDNA spanning partial 18S, internal transcribe spacer 1 and 2 and the 5.8S gene is unique within GenBank. Genetically, as most similar PA (TM) ikrylova, Matjusova, Musilova et Gelnar, 2009 was found (97.5%). Moreover, a specimen of from , and a specimen from (L.) were collected during sampling in Kenya. Likewise, additional sampling of from the Blue Nile in Sudan revealed the presence of the newly described species. These findings represent the first records of gyrodactylids in both African countries.
