[Falahati Hossein Abad, A., Potapov, M., Sarailoo, M. H., Mehr, M. S. & Yazdanian, M. 2013. New records of Isotomidae (Collembola) from Golestan province (Iran). Munis Entomology & Zoology, 8 (1): 236-238] ABSTRACT: Family of Isotomidae belongs to the order of Collembola. These springtails with elongate and high cover of setae on surface of the body and equal abdomen segments differenced from others. In faunaistic study of Isotomidae family, several samples were taken from soil and leaf litter in different locations from Gorgan regions during 2010-2011. The specimens were extracted by heat in Berlese funnel and mounted on microscopic slides using Hoyer’s medium. Totally, Six species of the family Isotomidae are recorded from Gorgan area (Northern Iran): Anurophorus coiffaiti, Folsomia penicula, Isotomurus punctiferus, Isotomurus maculatus, Isotomurus sp. (aff. palustris-unifasciatus) and Isotoma sp. (aff. decorata-spinicauda). Apart from F. penicula, all species are new for Iran. Two species are possibly new for science. KEY WORDS: Collembola, Arthropleona, Isotomidae, Golestan, Gorgan, Iran. Isotomidae is one of the largest families in Holarctic (Hopkin, 2005). Most of species of this family live in soil and are the primary and secondary consumers (Chahartaghi et al., 2005). Fauna of the family of some territories of Asia remains, however, poorly studied. Iran, a big country with diverse nature conditions, was paid very little (if not the least) attention by collembologists. Cox (1982), was the first to publish the list of Collembola recorded in Iran. 70 species (with 17 of which belonging to the family Isotomidae) from the Northwestern and Northern Provinces of the country was recorded by him. Moravvej et al. (2007) reported 5 isotomid species and so far the fauna of the family comprises 19 members. Our material was collected by the first author and is deposited in the insect collections of the Gorgan University of Agricultural Sciences and Natural Resources, Iran, and the Moscow State Pedagogical University, Russia. The fauna of Iran is still poorly studied, no keys to species is available, and new species are waiting their examination in future. MATERIALS AND METHODS Collection springtails: Soil and leaf litter samples were collected mainly from Gorgan areas, during 2010 and 2011. All samples were retained in white plastic boxes and then were transferred to the Entomology Laboratory of, Department of
