Summary - A root-knot nematode, Meloidogyne fallax n. sp., is described and illusuated from tomato (Lycopersicon esculeruum Mill.) from The Netherlands; this new species is characterized by : female stylet dorsaily curved, 14.5 I-lm long, with rounded to uansversely ovoid knobs, slightly sloping posteriorly; perineal panern with a moderately high dorsal arch with coarse suiae, indistinct 1atera1lines and venual region oval to angular; male stylet 19.6 I-lm long, with large rounded knobs, set off from the shaft; male head region slightly set off, round raised labial disc and distinct lateral lips present; second-stage juvenile 403 I-lm long, tail 49.3 I-lm long tapering graduaily until distinct hyaline tail terminus 13.5 I-lm long with broadly rounded tip. So far, the known distribution in Europe is resuicted to a smail number of locations in the south-eastern part of The Netherlands.
