On five species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) recently described from India

Examination of paratypes of five species of Xiphinema from India described by Singh and Khan (1998) led to the following conclusions: X. larliani Khan & Singh, 1998 appears a valid species close to X. simillimum Loof & Yassin, 1971. The other four species are considered junior synonyms, X. digicaudatum of X. brasiliense Lordello, 1951; X. gracilicaudatum of X. radicicola Goodey, 1936; X. arunachalense of X. brevicollum Lordello & Da Costa, 1961; X. pruni of X. basiri Siddiqi, 1959. Complementary morphological data, measurements and illustrations based on the paratypes are given for the five species.
