Abstract :

Family of Isotomidae is the second largest family in the order of Collembola. These springtails are elongate and lack scales on the upper surface of the body. In contrary of Entomobyridae family, the abdominal segments are all of similar length. They live in soil, leaf litter in terrestrial ecosystem or in associated with freshwater in aquatic ecosystem. In a faunistic study of Isotomidae family, several soil and leaf litter samples were collected from different location of Sari regions during 2010-2011. The specimens were extracted by heat in Berlese funnel and mounted on microscopic slides using Hoyer’s medium. Totally, eight species of seven genuses from this family were identified as follows: Isotomiella minor, Folsomia candida, Isotoma viridis, Folsomides parvulus, Proisotoma minima*, Isotomurus cf. italicus*, Isotomurus sp.* (aff. palustris-unifasciatus), Cryptopygus* cf. ponticus. The marked species by * are considered as new records for Collembola fauna of Iran.
