Daptonema<em> brevisetosum</em> sp. nov. resembles to <em>Daptonema setosum </em>(Bütschli, 1874), but differs from it by the relatively shorter outer labial setae, shorter spicules and shorter cervical and somatic setae. <em>Subsphaerolaimus major </em>sp. nov. similar to <em>Subsphaerolaimus lamasus </em>(Gerlach, 1956), <em>Subsphaerolaimus gerlachi </em>(Wieser, 1959) and <em>Subsphaerolaimus litoralis </em>Lorenzen, 1978, but differs from them by the longer body, longer spicules and presence of dorso-caudal apophysis of gubernaculum. <em>Daptonema hirtum </em>(Gerlach, 1957) is restored from synonymy of <em>Daptonema setosum </em>(Bütschli, 1874) and it is raised to range of valid species.</p> ER -
