نخستین گزارش از جنس Neodolichodorus Andrássy, 1976 از زیرخانواده Chitwood in Chitwood & Chitwood, 1950 Dolichodorinae در ایران

The genera are recorded from Telotylenchinae Siddiqi, 1960 and Merliniinae Siddiqi, 1971 from Iran, yet. Neodolichodorus from Neodolichodorinae have 12 ectoparasitic species that are recorded from different parts of the world. This genus is differed with body strongly curved or arcuate, lateral field with four incisures and amphidial apertures small, dorso-ventral slits. Cephalic region annulated or smooth, offset or continuous, not prominently lobed; labial disc present, generally not prominent; cephalic framework strongly sclerotized. Stylet elongate with conus longer than shaft; Basal bulb offset and median bulb well developed. Females are amphidelphic and vaginal sclerotization in lateral view is prominant. Female tail variable from short obtusely rounded or mammillate, with annulations following its contour to spicate and elongate-conical. Phasmids near anal. Male tail short, bursa large, trilobed. Spicules slender, with a small knob-like tip. The species from this studies is collected from root of mangrove in Hormozgan province. This species is characterized by female length 2161-2407 micrometers, stylet 73-87 micrometers, conus 42-49 micrometers, tail length 100-132 micrometes and males with 1795-2185 micrometers, stylet 71-85, conus 40-48 micometer, tail length 40-49 micrometers and spicules with 51-58 mirometers. Morphological and morphometrical character of this species is agreed with Neodolichodorus sinensis Zhuo, Wang & Liao, 2010. Also there are significant interaspecies variation between Iranian population and original description of this species. This variation is phasmid locality, shape of female tail, length of female tail, length of gubernaculum and excretory pore locality. This species related with root of mangrove in China for the first time. In this study, Iranian population are very abundant in root of mangrove and it is possible this species come a minatory factor of mangrove jungles. This record is the first study of this species after original description and phylogenetical relationships was done for the first time.
