A New Species of Mathevotaenia (Cestoda: Anoplocephalidae) and Other Tapeworms From Marsupials in Argentina

A new species of Mathevotaenia (Cestoda, Anoplocephalidae, Linstowiinae) from the lizard Sceloporus malachiticus (Squamata, Phrynosomatidae) from Panama

“…A comparison of the two species is given in Table I. It should be noted ( Table I) that measurements of various structures given by dos Santos (1968) are much larger than measurements given in the original description (Janicki 1904) or in the two later redescriptions (Gomes 1979, Campbell et al 2003 of M. bivittata. It would appear to us that dos Santos (1968) has described a marsupial cestode other than M. bivittata.…”

“…nov. is most similar to M. bivittata in that mature eggs are concentrated along the lateral margins of the proglottids. Major differences (per Campbell et al 2003) between the two species include oval cirrus sac in M. bivittata, a spherical cirrus sac in M. panamaensis; ovary compact consisting of 10-15 short lobules in M. bivittata, ovary bilobed with each lobe consisting of 3-4 lobules in M. panamaensis. A comparison of the two species is given in Table I.…”

Endoparasites of the Long-Eared Hedgehog (Hemiechinus auritus) in Zabol District, Southeast Iran

“…Previously, this cestode was reported in hedgehogs from Algeria (23) and Iraq (16). Several species of Mathevotaenia were reported before from different kinds of insectivorous mammals, especially rodents, worldwide (16,28).…”

Endoparasites of Fat-Tailed Mouse Opossums (Thylamys: Didelphidae) from Northwestern Argentina and Southern Bolivia, with the Description of a New Species of Tapeworm

“…Interestingly, the other species in the genus that occur in marsupials are known only from low-altitude habitats, with the most widespread (M. bivittata) ranging from Panamá to Argentina (Campbell et al, 2003). Whether this is a reflection of the effort of field biologists collecting mammals from these habitats or is an actual biological characteristic of this cestode/host association remains to be tested with additional sampling in these and other areas, particularly as the host species, T. pallidior, exhibits the broadest geographic and elevational range in the genus.…”

“…In Argentina, the cestodes M. argentinensis and M. bivittata were collected from both Didelphis albiventris Lund, 1840 and Micoureus cinereus Temminck, 1824, respectively (Campbell et al, 2003). Those specimens, as well as most other species of Mathevotaenia in the Neotropics, were collected from localities at relatively low altitudes.…”
