Neoskrjabinolepis nuda n. sp. from shrews on Sakhalin Island, Russia, with a taxonomic review of Neoskrjabinolepis Spasskii, 1947 (Cestoda: Cyclophyllidea: Hymenolepididae).
Neoskrjabinolepis (Neoskrjabinolepidoides) nuda n. sp. is described from the shrews Sorex unguiculatus (type-host), S. gracillimus, S. isodon and S. caecutiens on Sakhalin Island, Russia. The new species is characterised by: rostellar hooks 40-44 microm long and provided with small epiphyseal thickening of the handle; a long (95-100 microm) cirrus consisting of basal region with claw-shaped spines, a parabasal region with thin needle-shaped spines and an unarmed distal region; a cirrus-sac extending well into the median field; and 15-22 eggs per gravid uterus. A review of the species of Neoskrjabinolepis Spasskii, 1947 is presented. Currently, this genus includes nine species and is divided in two subgenera on the basis of strobilar development, which is gradual in the subgenus Neoskrjabinolepis (four species) and serial in the subgenus Neoskrjabinolepidoides Kornienko, Gulyaev & Mel'nikova, 2006 (five species). An amended generic diagnosis and an identification key to Neoskrjabinolepis spp. are presented.
