Meggittina numida n. sp. (Cyclophyllidea: Catenotaeniidae), a parasite of the Shaw's jird Meriones shawi (Duvernoy) (Rodentia: Gerbillinae) in Tunisia.
Meggittina numida n. sp. (Cyclophyllidea: Catenotaeniidae: Skrjabinotaeniinae) is described from the small intestine of the Shaw's jird Meriones shawi (Duvernoy) (Rodentia, Muridae, Gerbillinae) trapped in central Tunisia. The new species can be distinguished from the four other members of Meggittina Lynsdale, 1953 by the high number of proglottids (8-25 vs max. 6) and by the elongated strobila (8.2-60 mm in length vs max. 5.6 mm). M numida n. sp. further differs from M. cricetomydis (Hockley, 1961) in the direction of gravid proglottids; from M. baeri Lynsdale, 1953 in having narrower and much longer strobila; from M. aegyptiaca (Wolfgang, 1956) in the greater number of testes and the larger cirrus-sac; and from M. gerbilli in the position of the genital pore. The diagnosis of Meggittina is amended in order to include the most specific features of M. numida n. sp. as follows: strobila consisting of a small scolex, wide neck and one to twenty-five proglottids. This is the first species of Meggittina described from Tunisia. The taxonomic relationships of Meggittina spp. are discussed in the light of the description of the new species.
