Ochetostoma baronii, O. capense, O. myersae and O. formosulum aredistinct from O. natalense in possessing an interbasal muscle that passes through aloop of the neuro-intestinal vessel. In addition, there are several other differencesin the proboscis, integument and dermal papillae that separate the above speciesfrom O. natalense. Ochetostoma hupferi from Nyango, West Africa, is based on a singledamaged specimen recorded from a depth of 11 m. In this species, the trunk issmall, light yellow in colour and covered with small, uniformly distributedpapillae. The proboscis is 5 mm in length and the ventral setae are large, golden-yellow in colour. Fischers description (1895) mentions that the longitudinalmuscle layer is gathered into 10-11 bands.
