Abstract

Cestodes of the genus Davainea Blanchard 1891, from grouse in various Eurasian and North American regions have been identified as D. tetraoensis Fuhrmann 1919, or less frequently as D. proglottina (Davaine 1860). Those from ptarmigan (Lagopus spp.) in Alaska, resembling D. tetraoensis in some details but having only a single row of rostellar hooks and fewer testes, were earlier reported as D. proglottina by Babero (1953). The study of additional material from grouse from Alaska indicates that this cestode is specifically distinct from the two species mentioned. It is described here as new.

German abstract: Beschrieben wird eine neue Cestodenart, Davainea lagopodis sp. nov., die in H ühnerv ögel in Alaska weit verbreitet ist. Die neue Art unterscheidet sich von der naheverwandten D. tetraoensis Fuhrmann, 1919, durch die Form der Strobila, durch die kleineren Anzahl der Rostellarhaken, die in einer Reihe sind, und durch verschiedene Gr össenverh ältnisse der Geschlechtsorganen; von D. progiottina (Davaine, 1860) durch die gr össere Anzahl der Proglottiden, durch die gr össere Anzahl der Hoden, und durch die gr össere L änge der Rostellarhaken.
