The study provides descriptions of two new species of Enterogyrus coexisting in the stomach of the Mozambique tilapia, Oreochromis mossambicus (Peters). Enterogyrus multispiralis n. sp. and Enterogyrus mashegoi n. sp. were collected from hosts sampled at Nwanedi-Luphephe Dam, Limpopo River System, South Africa. The two new species can be differentiated from other members of the genus based on the spirality characteristics of the cirrus. Enterogyrus multispiralis n. sp. has an unique 8/9-2-4 cirrus spiral formula. The length of the cirrus and its spriral formula 5-2-3 make E. mashegoi n. sp. morphometrically unique from other Enterogyrus spp. Sequences of the nuclear ribosomal DNA partial 18S and internal transcribed spacer (ITS1) and 28S were obtained and compared with available sequences of Enterogyrus in GenBank. This is the first record of data on 18S rDNA region of Enterogyrus spp. A phylogenetic comparison was conducted, which included all data available for Enterogyrus spp., but this was limited to 28S data. The closest species to both new species of the present study was an undescribed Enterogyrus sp. 2 from Sarotherodon galilaeus (Linnaeus) described from Senegal (i.e. 2.1 and 2.9% uncorrected pairwise genetic distance to E. multispiralis n. sp. and E. mashegoi n. sp., respectively). These species represent new records for Africa resulting in a total number of 12 described valid species.
