several soil samples were taken from western parts of iran. one of the samples col-lected from the rhizosphere of nectarine trees (prunus persica l.) in moghan, ardabil province, contained aprutides guidettii. the species subanguina picridis was recovered from leaf gall of serratula latifolia boiss (asteraceae) in the vicinity of mashhad, khorasan province. although this species showed remarkable differences from the origi-nal description, it was considered to be s. picrides considering the high level of variability described in the literature. both species are described in detail and documented with drawings. additional morphological data are illustrated by means of sem. subanguina picridis is described here for the first time from iran.
