Genus Longidorus Micoletzky, 1922 comprises ectoparasitic nematode species feeding on plant roots. Some of them have considerable economic importance directly as plant pests or indirectly as vectors of nepo-viruses. During an extensive study on longidorids in Romania Longidorus distinctus Lamberti, Choleva and Agostinelli, 1983 was recovered from vineyards (Vitis vinifera L.) in Alba county, alfalfa (Medicago sativa L.) in Prahova county and fruiting shrubs in Arges county. The two populations from Prahova and Arges counties were characterised morphometrically. An integrative approach (morphology, morphometrical and DNA sequencing data) was used to identify and characterise the population from Alba county. The phylogenetic position of the species and the D2-D3 28S rDNA sequence dissimilarity with the closest species were discussed. All studied populations have been compared with other European populations; described from Bulgaria, hitherto L. distinctus has been reported from Serbia, Slovakia, Ukraine, Russia and Poland from arable land and natural habitats. It represents a new geographical record for Romania.
