V.G. Gagarin & Vu Thanh Nguyen

Abstract. Descriptions and illustrations of Terschellingia longisoma sp. n. and Sphaerotheristus parvus sp. n. are given. T. longisoma sp. n. is close to T. siphonolaimoides (Wieser, 1956) and T. capitata Vitiello, 1969. It differs from T. siphonolaimoides in the shorter and thinner body, shorter cephalic setae, absence of cervical setae, position of vulva, and from T. capitata in the longer and thinner body, shorter and thicker tail and larger amphidial fovea. S. parvus sp. n. is close to S. supoti Timm, 1968, but differs from it in the shorter stoma and shorter and differently shaped spicules.
