Diouf, Malick, Daouda, Is-Haquou & Durette-Desset, Marie-Claude, 2005, Two new species of Nippostrongylinae (Nematoda, Trichostrongylina, Heligmonellidae), coparasites of Mastomys natalensis (Muridae, Murinae) from Benin, Zoosystema 27 (1), pp. 27-35 : 28

N i p p o s t r o n g y l i n a e D u r e t t e -D e s s e t, 1 9 7 1, Heligmonellidae Skrjabin & Schikobalova, 1952 are widespread in Muridae Illiger, 1815 throughout the World, today. The Ethiopian representatives consist of the closely related genera Heligmonina Baylis, 1928 and Neoheligmonella Durette-Desset, 1970 ; the genus Heligmonina mainly diverging from the genus Neoheligmonella by the hypertrophy of the left ventral ridge (Durette-Desset 1 9 7 1). Heligmosomoid parasites from the small intestine of a single Mastomys natalensis from Benin (West Africa) were collected. In the present paper, two new coparasitic species are described, the first belonging to the genus Heligmonina and the second to the genus Neoheligmonella . It is the first record of Nippostrongylinae in this country. To date, H. chabaudi ( Desset, 1964) is the only Nippostrongylinae described from Mastomys natalensis .
