V.G. Gagarin

Abstract. The morphology and taxonomy of free-living nematodes of the genus Diplogasteritus Paramonov, 1952 are studied using the original material and literary data. The diagnosis of the genus Diplogasteritus is emended. Description of species, synonymy and a key to species are given. The following new synonymies are established: D. occidentalis (Steiner, 1932) = D. concolor (Massey, 1962) = D. austriacus (Fuchs, 1938); D. lineatus (Fuchs, 1915) = D. angustialaimus (Sch. Stekhoev & Tenuissen, 1938) = D. likoi Kokordak, 1963 = D. consorbinus (de Man, 1920) = D. stoeckherti (Volk, 1950) = D. taedus (Massey, 1962); D. nudicapitatus (Steiner, 1914) = D. aquaticus Gagarin, 1977 = D. ponderosus (Massey, 1962). Diplogasteritus arcuatus (Massey, 1962), D. brevicaudatus (Sch. Steckhoven & Tenuissen, 1938), and D. minutus (Kreis, 1929) are considered species inquirendae. Diplogasteritus paxi (Paesler, 1962), D. pterygatus (Timm, 1961) and D. subterraneus (Hnatewytsch, 1929) are considered species incertae sedis. Diplogasteritus primitivus sp. n. collected from rotten potatio in Yaroslavl Prov. of Russia is described and illustrated.
