Preference value means livestock preference to eat some plants relative to other plants or species. Accordingly, by studying the preference values, the range managers could determine the rangelands grazing capacity to achieve the optimum performance of livestock and to guarantee the stability of rangeland ecosystem. The objective of this study was to determine the preference value of perennial grasses using two methods of preference index (species feeding frequency) and sheep grazing time (feeding time recording) in a semi-steppe rangeland in the middle Alborz Mountains of Iran during four consecutive years (2010-2013). The collected data were tested for normality and then, analyzed by the software of SAS9.1. The means comparisons were made using the Duncan method. Results showed that sheep preferred five grass species (Bromus tomentellus, Festuca ovina, Dactylis glomerata, Agropyron intermedium, and Agropyron trichophorum) in the rangeland. There were significant differences between species and years for grazing time method; however, there were no significant differences for preference index. Also, there were significant differences between months within years for both methods. Results showed that A. trichophorum with the average value of 13.8% grazing time was ranked as the first species followed by D. glomerata with the average value of 11.1% as the second one (Grazing time method). There were no significant differences between A. trichophorum, B. tomentellus, D. glomerata and F. ovina regarding the preference index with the average values of 0.57, 0.75, 0.70 and 0.56, respectively. Overall, the results indicated that grazing time percent method in semiarid rangelands gives more realistic results as compared to the preference index method because of the concrete and tangible results.

Corononcodes ziegleri spec. nov. is described and illustrated based on material from Iran. The species represents the second Palaearctic representative of this panopine genus. In addition, C. siculus Bezzi is recorded from Fuerteventura (Canary Islands, Spain) for the first time. An identification key to the Palaearctic species of Corononcodes is presented. Additional faunistic records for the Iranian fauna comprise Acrocera orbiculus (Fabricius) and an apparently undescribed species of Ogcodes Latreille. DNA-barcodes for all Iranian taxa are provided.

An unusual new genus of Scenopinidae, Iranotrichia gen. n., comprising two newly discovered species (I. insolita sp. n. and I. nigra sp. n.), is described from Iran. Iranotrichia gen. n. are scenopinine window fies with a habitus reminiscent of certain bee fy genera (Bombyliidae), based on colouration and elongate mouthparts and antennae. Te phylogenetic placement of this distinctive new genus is discussed and a dichotomous key to world genera is presented. Te genus name Kelseyana nom. n. is proposed to replace Caenoneura Kröber, 1924, which was found to be preoccupied by Tomson (1870: 270) (Hymenoptera) and Kirby (1890: 136) (Odonata).

The genus Platypygus Loew, 1844 in Iran is reviewed. Platypygus kurdorum Paramonov and P. melinoproctus Loew are redescribed and a new species, Platypygus titanomedea sp. nov., is described and illustrated. A diagnostic key to species of Platypygus and Cyrtisiopsis in Iran is provided and variability of some characters in genus Platypygus is briefly discussed. As a result of this study, Platypygus maculiventris Loew is transferred to thegenus Cyrtisiopsis Séguy. © 2011 Magnolia Press.

Two new species, Empidideicus aurantiacus Gharali & Evenhuis, sp. nov. and Empidideicus unicus Gharali & Evenhuis, sp. nov., are described and illustrated from the north of Iran. An updated key to species of Empidideicus Becker, 1907 in Iran and the neighbouring countries gto the north is presented. © Kasparek Verlag, Heidelberg.
