Four Rotylenchus species new for Romania with a morphological study of different Rotylenchus robustus populations (Nematoda: Hoplolaimidae)

Abstract

Specimens of Rotylenchus lobatus, R. buxophilus, R. capensis, R. cf uni/ormis and R. robustus were collected primarily from habitats located in the Romanian Carpathians. Brief redescriptions, measurements, illustrations and data referring to the habitat are given for these species. The morphological variation of five populations of R. robustus is discussed.
