Abstract

The ectoparasite Plesiorotylenchus striaticeps n. gen., n. sp., obtained from the rhizosphere of grapevines at Osman, Turkey, is described. The new genus is close to Rotylenchus Filipjev, 1936, but differs from it and is characterized by the presence of a lip region with longitudinal striae radially disposed and a rectangular labial disc. Plesiorotylenchus n. gen. is considered as Hoplolaiminae because of the short and rounded tail with annulation following its contour, phasmids near anus, strong stylet and labial framework. Bursa not indented terminally. Plesiorotylenchus striaticeps n. sp. is characterized by a truncate lip region in profile with 35-40 longitudinal striae, C-shaped habitus and oesophageal gland overlapping intestine with three gland nuclei.
