Abstract

A relatively small root-knot nematode, Meloidogyne minor n. sp., is described and illustrated from tomato from the Netherlands. This new species is characterised by the following features: female with dorsally curved stylet, 14 Pm long, with transversely ovoid knobs slightly sloping backwards from the shaft; perineal pattern rounded; male stylet 18 mum long, large transversely ovoid knobs slightly sloping backwards from the shaft; head region not set off, labial disc elevated, lateral lips prominent; and second-stage juvenile 377 mum long, with hemizonid posterior adjacent to excretory pore; tail 54 mum long; and a distinct hyaline tail terminus 16 pm long. Additionally, distinguishing information on isozymes, DNA, cytogenetics and host plants is presented. Meloidogyne minor n. sp. has so far been found on potato in the Netherlands and has been detected in the British Isles on several golf courses, associated with yellow patches, often together with M. naasi.
