title: Discopersicusn. gen., a New Member of the Family Tylenchidae Örley, 1880 with Detailed SEM Study on Two Known Species of the GenusDiscotylenchusSiddiqi, 1980 (Nematoda; Tylenchidae) from Iran.
abstract: Discopersicus iranicusn. gen., n. comb., previously described from Iran as a new species under the genusDiscotylenchus, is illustrated using light microscope and scanning electron microscope (SEM) observations and further studied using molecular characters. SEM studies revealed the newly proposed genus has oblique amphidial apertures on the lateral sides of the lip region. SEM images are also provided for two species ofDiscotylenchus, namelyD. discretusandD. brevicaudatus, as the first SEM study of the genus.These results confirmed longitudinal amphidial aperture type on lateral sides of the lip region in genusDiscotylenchus, as noted by Siddiqi while erecting the genus withD. discretusas the type species.Molecular phylogenetic analyses using partial small subunit (SSU) and large subunit (LSU) rDNA sequences revealed the affinity of the genusDiscopersicusn. gen. with members of the subfamily Boleodorinae, as supported by morphological characters (mainly, the oblique amphidial opening).
