- Abstract
Summary: A population of the genus Devibursaphelenchus was collected from the inner part of the decaying Persian oak tree (Quercus brantii) from Lordegan city of Chaharmahal va Bakhtiari Province, Iran. The morphological and molecular characters confirmed the new species, namely D. lordeganensis sp. n. The new species is characterised by female body length (768-1026 μ m), lip region separated from the rest of the body by a slight constriction, obscure lines on lateral fields, stylet length long, slender, wide-lumened, tripartite, composed of a conus with an aperture about half its length, a conophore about equal with the conus, and a shaft, taller than (conus + conophore) length, lacking basal knobs or swelling, excretory pore ca three metacorpal lengths posterior to the base of the metacorpus, post-uterine sac (PUS) (36-67 μ m long; 1.3-3.7 times longer than vulval body diam.), absence or vestigial of rectum and anus, posterior end of the body conical with a rounded tip (in some specimens with a spherical protruded projection at tail tip), males 668 to 815 μ m long, presence of two pairs of caudal papillae (P2 and P3), spicule length (15-17 μ m) with long and wide bladed condylus, triangular rostrum with a blunt tip and small bursa flap ending at the tail tip. The molecular phylogeny based on 28S rDNA revealed that the new species stands close to D. alienae (LC629160) and D. lini (FJ768944, AM396570). The measurements, line illustrations, light microscopy photographs and phylogenetic analysis are given for the new species. In addition, a key to the species of Devibursaphelenchus is given.
