Longidoridae from Bulgaria (Nematoda, Dorylaimida) with description of three new species of Longidorus and two new species of Xiphinema

Information on the presence of longidorid nematodes in Bulgaria are scanty and incomplete (Stoyanov, 1964; Choleva, 1975a, 1975b and 1976; Katalan-Gateva, 1980). Therefore, we thought it useful to report here the results of an extensive survey of species belonging to the family Longidoridae carried out in this country in the period 1972-1981, to contribute to the knowledge on the geographical distribution of species of Longidorus, Paralongidorus and Xiphinema in Europe and in the Mediterranean Region.
