Two new species of Longidorus (Nematoda: Longidoridae) from Italy


  • F. Lamberti
  • Teresa Bleve Zacheo


In 1971 (Prota et al., 1971) a species of Longidorus (Micol.) Filipjev collected in a vineyard in Sardinia was identified and described as L. attenuatus Hooper, but it was emphasized that the specimens examined differed from British and German populations in having a shorter, more robust tail with rounded terminus, which in the latter is rather pointed. A series of publications between 1973 and 1976 (Rana and Roca, 1973; Roca et al., 1975; Roca et al., 1975; Vovlas and Roca, 1975; Rana and Roca, 1976; Taylor et al., 1976) report an Apulian population belonging to the same genus and again identified as L. attenuatus, as the vector of strains of Artichoke Italian Latent virus. A more detailed study of our material and comparison with specimens of similar species and of British or German populations of L. attenuatus indicate that we are dealing with two new species. They are described here from specimens killed either in hot 5 % formalin or TAF, fixed in the same media and mounted in glycerine by the slow method (Lamberti and Sher, 1969).
