Aploparaksis (Tanureria) borealis Bondarenko and Rausch, 1977

Hosts. Stercorarius longicaudus Vieillot , Anthus cervinus (Pallas) , Calcarius lapponicus (Linnaeus) , Emberisa sp.

Intermediate hosts. Mesenchytraeus sp. (unpublished experimental data).

Metacestode. Autotomicercus ( Bondarenko and Kontrimavichus 1976b).

Localities. North America (Alaska), Siberia (the lower reaches of the Ob’, Enisey and Lena Rivers, Chukotka) .

Remarks. Bondarenko and Rausch (1977) described this species on the basis of numerous specimens collected in 1966 in one S. longicaudus from Seward Peninsula (Alaska) by R. Rausch, and those collected by S. Bondarenko from passeriform birds A. cervinus and C. lapponicus from Chukotka in 1970–1973. On the basis of the topography of the female gonads, we now transfer the species to the subgenus Tanureria . During the present study, we re-examined unidentified specimens from C. lapponicus from eastern Chukotka (INPA Nos. 7, 40, 119, 121, 239, 241,242, 234 and 254). Our observations showed that they belong to A. borealis . The results of the current investigation confirm that A. borealis is a common parasite of passeriform birds. For the morphology of A. borealis see Bondarenko and Rausch (1977).
