Abstract

The paper contains descriptions of two new species of the genera Pterygorhabditis Timm, 1957 and Aspidonema (Sachs, 1949) Andrássy, 1958 belonging to the families Pterygorhabditidae Goodey 1963 and Bunonematidae Micoletzky 1922, respectively. Species were procured from fixed samples, collected earlier from aquatic habitats. Pterygorhabditis punctata n. sp. is characterized by a cuticle with flattened hexagonal blocks arranged in eight longitudinal rows in both sexes; each metastegostomal plate with a minute denticle, and males with long, slender, fused spicules and nine pairs of post-cloacal, prominently setose genital papillae. Aspidonema formosa n. sp. is the first report of the genus from India. The species is characterized by the right side provided with 35–48 pairs of warts flanking a row of smooth membranous shields and surrounded by a well-developed network and an anisomorphic metastegostom without discernible armature. Species are compared with other congeners, together with the diagnoses of amended genera, and keys to the identification of species are provided.
