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 <em>L. extremus</em> (Daneshvar, 1987) with <em>Lasioseius parberlesei</em> Bhattacharyya as previously proposed by Moraes<em> et al.</em> (2015). In addition, we provide the first description of the male of <em>L</em>.<em> parberlesei</em> in Iran. Moreover, this paper provides a checklist for <em>Lasioseius </em>species recorded from Iran, with a key for identification of the species. https://www.persianacarology.org/article_238276_07ebb31b3c9b5840bd872becb85537f5.pdf
