![]() ![]() ![]() ![]() Soil nematode gross morphology tends to be highly conserved, making species identification a very difficult task. The phylum Nematoda comprises the most species-rich metazoans on earth with a global distribution and estimated realistic number of species of ca. This study represents the most complete phylogenetic analysis for Longidorus species to date. based on three molecular markers resulted in a general consensus of these species groups, since lineages were maintained for the majority of species. Results of molecular and phylogenetic analyses confirmed the morphological hypotheses and allowed the delimitation and discrimination of six new species of the genus described herein and four known species. We developed a comparative study by considering morphological and morphometrical features together with molecular data from nuclear ribosomal RNA genes (D2–D3 expansion segments of 28S, ITS1, and partial 18S). We also found evidence of some geographic species associations to western ( viz. vineacola), and two additional new records for wild olive ( L. nov.), two new records for wild and cultivate olives ( L. The present study doubles the known biodiversity of Longidorus species identified in olives by including six new species ( Longidorus indalus sp. We provide the first detailed information on the diversity and distribution of Longidorus species infesting wild and cultivated olive soils in a wide-region in southern Spain that included 159 locations from which 449 sampling sites were analyzed. ![]() Thus, correct identification of Longidorus species is essential to establish appropriate control measures. Damage is caused by direct feeding on root cells as well as by transmitting nepoviruses that cause disease on those crops. The genus Longidorus includes a remarkable group of invertebrate animals of the phylum Nematoda comprising polyphagous root-ectoparasites of numerous plants including several agricultural crops and trees. ![]()
