Descriptions, illustrations and differential diagnoses for two new species of Neoskrjabinolepis Spassky, 1947, i.e. N. (Neoskrjabinolepis) fertilis n. sp. and N. (Neoskrjabinolepidoides) hobergi n. sp., are given. Neoskrjabinolepis (Neoskrjabinolepis) fertilis was found in the shrew Sorex tundrensis Merriam on the Seward Peninsula (Alaska, USA) and from the mouth of the Anadyr River (Chukotka, Russia), and N. (Neoskrjabinolepidoides) hobergi was found in Sorex tundrensis on the Seward Peninsula (Alaska, USA). Neoskrjabinolepis fertilis n. sp. is characterised by having: rostellar hooks 38-42 μm long and provided with a small epiphyseal thickening of the handle; a long cirrus (85-100 μm), consisting of a basal region with claw-shaped spines and a parabasal region with small, thin needle-shaped spines; a cirrus-sac extending well into the median field; and 55-70 eggs per gravid uterus. Neoskrjabinolepis (Neoskrjabinolepidoides) hobergi n. sp. is characterised by having: rostellar hooks 63-65 μm long and provided with a large epiphyseal thickening of the handle; a short cirrus (45-50 μm), consisting of a basal region with small claw-shaped spines and a parabasal region with thin, needle-shaped spines; cirrus-sac reaching slightly into the median field; and 36-45 eggs per gravid uterus.
本文给出了1947年斯帕斯基（Spassky）所定新棘颚口线虫属（Neoskrjabinolepis）的两个新物种，即肥沃新棘颚口线虫（Neoskrjabinolepis (Neoskrjabinolepis) fertilis n. sp.）和霍氏新棘颚口线虫（Neoskrjabinolepis (Neoskrjabinolepidoides) hobergi n. sp.）的描述、图示及鉴别诊断。肥沃新棘颚口线虫（Neoskrjabinolepis (Neoskrjabinolepis) fertilis）发现于美国阿拉斯加苏厄德半岛的苔原鼩鼱（Sorex tundrensis Merriam）以及俄罗斯楚科奇阿纳德尔河口，霍氏新棘颚口线虫（Neoskrjabinolepis (Neoskrjabinolepidoides) hobergi）发现于美国阿拉斯加苏厄德半岛的苔原鼩鼱。肥沃新棘颚口线虫新物种的特征为：吻钩长38 - 42μm，柄部有小的骨骺增厚；交接刺长（85 - 100μm），由基部具爪形刺和副基部具小而细的针形刺组成；交接囊深入到中区；每个妊娠子宫含55 - 70枚虫卵。霍氏新棘颚口线虫新物种的特征为：吻钩长63 - 65μm，柄部有大的骨骺增厚；交接刺短（45 - 50μm），由基部具小爪形刺和副基部具细针形刺组成；交接囊稍伸入中区；每个妊娠子宫含36 - 45枚虫卵。
