Some tobrilids (Nematoda, Tobrilidae) from Kuril'skoe Lake (Kamchatka Peninsula, Russia) [Russian]

摘要

Three new species of nematodes of the family Tobrilidae (Tobrilus minor, T. kanitschaticus, Eutobrilus major) and male of Epitobrilus allophysis found in Kuril'skoe Lake are described. Tobrilus minor sp. n. is close to T. parvus Gagarin 1991, but differs from it by longer cephalic setae, another position of vulva, and the absence of biocrystals. T. kanitschaticus sp. n. resembles T. gracilis (Bastian, 1865), but differs from it in the wider labial region, longer cephalic setae, longer spicules, and another shape of tails. Eutobrilus major sp. n. is similar to E. steinery (Micoletzky 1925) and differs from it in a thicker body, longer tail, longer cephalic setae, longer spicules, and the absence of biocrystals.
