A review on genus Calvolia Oudcmans, 1911 (Acari: Winterschmidtiidae) with a new record for Iranian fauna

The fauna of Astigmatid mites in birds' nest was studied in Isfahan province of Iran. During 2014-2016 Calvolia priapus Volgin 1990 was collected from the Eurasian magpie or common magpie nest, Pica pica (Passeriformes: Corvidae). This is the second time definition of this species from the world and characters were compared with the first record. Some characters are different might be because of the difference in geographical collection sites. Since the first pictures in the original record were not clear, we draw the male and female figures by drawing tube. We also presented identification kay for all species of calvolia genus.This is a new record for Astigmata fauna of Iran.
