A New Species of Oochoristica (Cestoda: Anoplocephalidae: Linstowiinae) in the Lizard Teius teyou (Squamata: Teiidae) from Argentina

摘要

Oochoristica bivitellobatoides n. sp. (Cestoda: Anoplocephalidae: Linstowiinae) from a four-toed tegu, Teius teyou, collected in Argentina is described. The new species is most similar to Oochoristica bivitellobata in that, in both species, the ovary and vitellarium are bilobed. Major differences between the 2 species involve ovary and vitellarium structure: 8-12 lobules in each lobe of ovary and vitellarium in O. bivitellobatoides; scalloped margin of ovary and compact vitellarial lobes in O. bivitellobata.
