Review of the genus Lasioseius Berlese (Acari: Blattisociidae) in Iran, and a key for identification of the Iranian species of the genus

The mites of the genus Lasioseius Berlese in Iran are reviewed. New collection data on seven species of the genus are given for Guilan province in Northern Iran. Based on our observations of newly collected specimens, we confirm the synonymy of L. extremus (Daneshvar, 1987) with Lasioseius parberlesei Bhattacharyya as previously proposed by Moraes et al. (2015). In addition, we provide the first description of the male of L. parberlesei in Iran. Moreover, this paper provides a checklist for Lasioseius species recorded from Iran, with a key for identification of the species.
