Paranoplocephala sciuri (Rausch, 1947) (Cestoda: Anoplocephalidae), a Parasite of the Northern Flying Squirrel (Glaucomys sabrinus), with a Discussion of Its Systematic Status

摘要

This study redescribes Andrya sciuri Rausch, 1947 (Anoplocephalidae) from the northern flying squirrel, Glaucomys sabrinus (Shaw), in North America, to redefine the morphology and generic position of this poorly known cestode Andrya sciuri is shown to belong unambiguously to the genus Paranoplocephala Liihe, 1910 sensu Haukisalmi and Wickstrom (2005). Paranoplocephala sciuri is compared with 4 species that resemble it morphologically, and features that can be used in its identification are presented, It is suggested that P. sciuri has speciated through a shift from arvicoline rodents (voles and lemmings) to G. sabrinus.
