[Setaria species from water buffalo of Southeast Asia and from Caffer Buffalo of Africa: comparative study with Setaria spp. from cattle of the respective areas (author's transl)].

Setaria leichungwingi Chen, 1937 (stat. nov.), parasite of Bubalus bubalis in Asia is closely related to S. labiatopapillosa, but the peribuccal chitinous crown is different. Until now, specimens determined as S. labiatopapillosa in Africa pertain in fact to two species S. labiatopapillosa sensu stricto and a new species described here: S. nelsoni n.sp., characterised by peribuccal crown's form (similated to that of S. leichungwingi) and by narrow host-sepcificity. It differs from S. leichungwingi by thick spiny extra-projections in higher percentage on peribuccal crown and by fewer spiny formations on the end of the female. A table gives the determination of the Setaria from Buffalo of the regions between India and East Europe with that from cattle. In the area, Setaria sp. from Bubalus is closely related to but different from S. labiatopapillosa.
