AI Article Synopsis
- - A new species called Discopersicus n. sp. has been identified and described from a carrot rhizosphere population in Dezful, Iran, characterized by various body measurements and features.
- - Key morphological traits include a body length of 601-734 µm, prominent labial disc, specific stylet and spicule sizes, and a uniquely shaped tail.
- - The new species differs from its only close relative, D. iranicus, by having an anterior vulva position, shorter stylet, different tail tip shape, and smaller male spicules; molecular analysis confirms its phylogenetic placement.
Article Abstract
Discopersicus n. sp., is described and illustrated from a population associated with the rhizosphere of carrot ( L.) in Dezful, Khuzestan province, south-western Iran. Based on morphological and morphometric data, the new species is characterized by a 601-734 µm long body, a prominent perioral labial disc and oblique amphidial slits, 10-11 µm long stylet, vulva at 65-67% of body length, 15.5-17 µm long spicules, and an elongate conoid tail with a pointed terminus. It is the second species of the genus Discopersicus and differs from its counterpart D. iranicus, by its anterior position of vulva, shorter stylet, lower M.B. ratio, different shape of tail tip, and shorter spicules in male specimens. A molecular phylogenetic analysis using the D2-D3 expansion segments of 28S rDNA sequences, placed the new species in close relationship with five sequences of the genus .
