Three new species of Longidorus (Nematoda, Dorylaimida) from Italy

Abstract

Longidorus iuglandis, L. picenus and L. eridanicus are three new species described from Italy. The first differs from L. caespiticola Hooper, 1961 in its longer odontostyle and bilobed amphidial pouch, from L. profundorum Hooper, 1966 in its longer odontostyle and lower value of the ratios a and c', from L. moesicus Lamberti, Choleva and Agostinelli, 1983 in having a more flattened anterior extremity and lower ratios a and c'. L. picenus differs from L. caespiticola Hooper, 1961 and L. macrosoma Hooper, 1961 in its bilobed amphidial pouches and from L. goodeyi Hooper, 1961 in its longer odontostyle and shorter tail and from L. profundorum in its longer odontostyle and more robust body. L. eridadanicus differs from L. taniwha Clark, 1963 and L. iranicus Sturhan and Barooti, 1983 in its longer odontostyle, more rounded tail and shorter body length.
