Neoskrjabinolepis merkushevae sp. n. (Cyclophyllidea: Hymenolepididae), a new cestode from shrews from the Palaearctic region.

Neoskrjabinolepis (Neoskrjabinolepidoides) merkushevae sp. n. is described from the shrew Sorex minutus L. (type host) from Belarus. The new species is characterised by rostellar hooks 35-37 microm long, provided with small epiphyseal thickening of the handle; short (35-40 microm) cirrus consisting of a basal part with claw-shaped spines, a parabasal part with thin needle-shaped spines and an unarmed distal part; cirrus-sac slightly passing into median field; and 12-16 eggs per gravid uterus. In addition to the type host and the type locality, the host range of the new species includes Sorex araneus L. and there are geographical records from Bulgaria, Lithuania and North-East Altay (Russia).
