Abstract

Recently collected populations of Neodolichodorus citri sÕJacob & Loof, 1996 from Uruguay were used for additional (LM and SEM) illustrative and descriptive morphological observations of the species, including information on the copulatory plug which seals off the vulval area in about 60% of female specimens. This species, known until the present study only from the type locality and host, has been found also in the rhizosphere of plum (Prunus domestica L.), peach (Prunus persica L.), corn (Zea mays L.) and Chenopodium sp. at three different Uruguayan localities. With its unstriated lip region, N. citri can be compared only with N. leiocephalus and N. rageshi. From the first it differs mainly by the longer stylet and the shorter tail; from the second, it is easily separated by stylet length (shorter in N. rageshi), and by length and shape of the tail (longer and spicate in N. rageshi). N. citri can be also compared to N. rostrulatus, because of the labial area, incompletely divided into two annuli and appearing smooth in surface SEM view of N. rostrulatus. However, females of N. rostrulatus have both stylet and tail shorter than females of N. citri. An illustrated compendium to the ten valid species assigned to the genus Neodolichodorus Andr.ssy, 1976, based on the main taxonomic literature morphometrics, ratios, LM and SEM illustrations has been designed and presented, for an easier access to species identification.
