First report of two genus and five species of Collembola (Hexapoda: Entognatha) from Iran

In order to investigate the fauna of Collembola (springtails), several sampling were carried out from soil and leaf litter of different Sari regions during 2010- 2011. The Collembola were extracted from soil and leaf litter by heat and light in the system as Berlise funnel. Permanent microscopic slides were provided by Hoyer medium or mixture of lactic acid and glycerin (5:1). In this study the genus Orthonychiurus Stach, 1954 and Dicyrtomina Borner, 1903 were reported for the first time from Iran. Species of Xenylla welchi Tullberg, 1839, Orthonychiurus folsomi (Schaffer, 1900) and Dicyrtoma fusca (Lubbock, 1842), Dicyrtomina ornata (Nocolet, 1842) and Sminthurinus aureus (Lubbock, 1862) were new records for Iranian Collembola fauna. Sminthurinus elegans (Fitch, 1863) are new for Mazandaran fauna.
