TY - JOUR AB - A new needle nematode, Paralongidorus koreanensis n. sp., recovered from rhizosphere of Poa pratensis and Zoysia japonica from Korea, is described and illustrated based on inferences from morphological and molecular data. Additionally, the existence and taxonomic status of X. diffusum and X. insigne in Korea is also duly confirmed. Phylogenetic inferences were based on an integrative approach considering the analyses of the 28S rRNA, ITS1 rRNA, SSU rRNA and the partial COI gene sequences. The new species is characterized by medium body length (4.2–5.5 mm); lip region rounded, slightly set off from the body by a shallow indentation, 15.0–18.3 μm wide; amphidial fovea stirrup shaped; guiding ring anteriorly positioned (28.6–33.6 μm from anterior end); odontostyle moderately long (99.4–109.7 μm); tail short (34.0–43.5 μm), hemispherical to bluntly rounded. Males rare in population. Spicules moderate, 70 μm long; 13 irregular spaced ventromedian precloacal supplements anterior to the adanal pair; four juvenile developmental stages clearly distinguishable. The new species is morphologically similar to P. bikanerensis, P. inagreinus, P. hanliae, P. spasskii, P. nudus, P. indicus and P. sali but differs from all, either by lip region shape and width, amphidial fovea shape, body and odontostyle length, female tail length and shape or spicule length. Sequence data analyses from amplified regions suggest that it’s a sister species to P. bikanerensis and P. sali, and the three species are consistently placed in a clade outside the main clade for Paralongidorus. Xiphinema insigne and X. diffusum DNA sequences were similar to the respective species sequences available in GenBank. A1 - Mwamula, A. O. A1 - Decraemer, W. A1 - Kim, Y. H. A1 - Ko, H.-R.
