A new pseudoscorpion species in Amblyolpium ( Pseudoscorpiones : Garypinidae ) from a house in Kermanshah Province , Iran

Amblyolpium goldastehae spec. nov., is described and illustrated on the basis of two males collected from western Iran. Its ability to live in a dry and xerotherme habitat is also discussed.

The family Garypinidae Daday, 1888, which was considered a subfamily of Olpiidae Banks until it was raised to family level by Judson (2005), currently contains 21 genera and over 78 species (Harvey 2013), of which only two species belonging to two genera have since been reported from Iran: Garypinus afghanicus afghanicus Beier, 1959 and Serianus validus (Beier, 1971) (Harvey 2013).Also, two species representing a new species of Garypinus and Amblyolpium bellum J.C. Chamberlin, 1930 have recently been identified from central and southern Iran by Nassirkhani & Harvey (in prep.).
The genus Amblyolpium Simon, 1898 was erected on the basis of the type species, A. dullfusi Simon, 1898, collected from Collobrières, a commune in the Var department in the Provence-Alpes-Côte d'Azur region in south-eastern France (Harvey 2013).The genus includes 15 known species, of which 13 are found in the Palaearctic, Oriental and Austroasiatic regions and two in the Neotropical region.It is only known from two species, A. anatolicum Beier, 1967 andA. bellum J.C. Chamberlin, 1930, in the Middle East, Central and South-Eastern Asia (Harvey 2013, Nassirkhani & Harvey in prep.).Recent collecting in western Iran revealed a new Amblyolpium species with an important difference in its trichobothriotaxy which is described and illustrated here.

Material and methods
The specimens used in this study are lodged in the collection of the Acarology Laboratory, Islamic Azad University of Arak (IAUA), Iran.The specimens were collected directly by hand, preserved in 70 % ethanol, cleared in 60 % lactic acid and prepared for study using black enameled pins (size 0 to 2).The holotype was permanently mounted on a dished glass microscope slide in Swan's fluid and the paratype was studied as a temporary slide prepared by immersion of the specimen in lactic acid.The prepared specimens were studied using an Olympus CH-2 compound microscope and illustrated with a drawing tube attachment.Measurements were taken by a calibrated ocular micrometer and the photograph was made using a digital camera (Canon PC1468).Chamberlin (1931), Legg (1974Legg ( , 1975)), Harvey (1992), Judson (2007) and Harvey et al. (2012) are the main references for morphological terminology and measurements.
The following trichobothrial abbreviations were employed: In addition, the following abbreviations are used in the text: L = length, W = width, D = depth.

Diagnosis
Differs from the other species of the genus by the following combination of characters: trichobothrium ist proximad of it, est at the same level as t; the presence of a long and a slightly long seta on the pedipalpal femur; and the pedipalpal size, e.g.femur is 0.42-0.45/0.11-0.12mm, patella 0.35-0.38/0.13-0.14mm and chela (with pedicel) 0.68-0.72/0.17-0.19mm.
