Arachnologische Mitteilungen 57

Arachnologische Mitteilungen / Arachnology Letters 57: 77-83 Karlsruhe, April 2019 So far, only three pseudoscorpion species, Acanthocreagris iranica Beier, 1976, Neobisium ( N .) alticola Beier, 1973 and Neobisium ( N .) validum (L. Koch, 1873), have been repor- ted from Lorestan province (western Iran) (Nassirkhani et al. 2017, Nassirkhani & Zamani 2017). Recent collections in Lorestan province resulted in a total of ten species belonging to three families, Olpiidae, Menthidae and Geogarypidae, of which Olpium lindbergi Beier, 1959 is recorded for the first time in Iran. There are no published descriptions of Olpium lindbergi , originally described from Afghanistan, and Geogarypus shulovi Beier, 1963, originally described from Israel, other than Beier (1959, 1963). Due to the presence of some variations noted within O. lindbergi and G. shulovi found in Lorestan province (western Iran), these two species are redescribed here.Moreo- ver, the diagnostic figures of these species are illustrated here because Beier (1959, 1963) only illustrated the pedipalps of the types in dorsal view, and there are no published illustra- tions of the other important characteristics which may assist in the identification of these species. Material and methods The specimens examined in this study were permanently mounted on glass microscope slides in Hoyer’s medium or studied as temporary slides made by glycerine, examined with an Olympus CH–2 compound microscope and illustrated using a drawing tube. Measurements were taken using a cali- brated ocular micrometer (WF10X–18MM). The specimens are deposited in the collection of the Acarology Laboratory, Arak branch, Iran (IAUA). Morphological terminology and measurements follow Chamberlin (1931), Harvey (1992), Harvey et al. (2012) and Judson (2007). Coordinates are given in the Geodetic System WGS 84.
