Some edaphic mesostigmatic mites from Lordegan, Chaharmahal Bakhtiari province with their world distribution

Soil-dwelling mites and especially Gamasina (Mesostigmata) are very important to soil ecosystems. They are one of the major groups rich in species and abundance. In order to study mesostigmatic mite fauna, soil samples were collected from different oak forests of Lordegan region. The mites were extracted using Berlese-Tullgren funnels and then cleared in Lactic acid and mounted in Hoyer's medium. This study reports on the distribution of soil mesostigmatids in Iran and world-wide. Twenty species belonging to ۱۳ genera of five families were collected and identified. Species are listed as follows: Ascidae: Arctoseius cetratus (Sellnick, ۱۹۴۰), Gamasellodes bicolor (Berlese, ۱۹۱۸), Antennoseius (Antennoseius) bacatus Athias-Henriot, ۱۹۶۱, Antennoseius (Antennoseius) masoviae (Sellnick, ۱۹۴۳). Blattisociidae: Lasioseius youcefi Athias-Henriot, ۱۹۵۹. Laelapidae: Cosmolaelaps rectangularis Sheals, ۱۹۶۲, Euandrolaelaps karawaiewi (Berlese, ۱۹۰۳), Gaeolaelaps aculeifer (Canestrini, ۱۸۸۳), Gaeolaelaps minor (Costa, ۱۹۶۸), Gaeolaelaps oreithyiae (Walter & Oliver, ۱۹۸۹), Haemolaelaps fenilis (Megnin, ۱۸۷۵), Haemolaelaps shealsi (Costa, ۱۹۶۸), Haemolaelaps schusteri (Hirschmann, ۱۹۶۶), Laelaspis kamalii Joharchi and Halliday, ۲۰۱۲, Laelaspis missouriensis (Ewing, ۱۹۰۴), Gymnolaelaps canestrinii (Berlese, ۱۹۰۳), Gymnolaelaps obscuroides (Costa, ۱۹۶۸). Ologamasidae: Sessiluncus hungaricus Karg, ۱۹۶۴, Allogamasellus sp.; Veigaiidae: Veigaia planicola Berlese, ۱۸۸۲. The genus Allogamasellus and Haemolaelaps schusteri are reported for the first time for Iranian mite fauna and the male of Laelaspis kamalii is reported for the first time for world fauna.
