                                                         Introduction
                            Pompilidae, also known as "spider wasps", is a moderately sized cosmopolitan family of
                            Hymenoptera, with approximately 5.000 species in  more  than  230  genera  worldwide
                            (WASBAUER 1995). They are slender wasps with long, spiny legs, posterodorsal margin
                            of pronotum usually weakly but sometimes moderately concave and somewhat quadrate,
                            also a very diagnostic transverse sulcus present across the mesopleuron. Typical
                            coloration tends to be black, black and red or yellow, sometimes with metallic reflection.
                            Most spider wasps are dark but some are brightly colored, with smoky or  yellowish
                            wings and some abdominal terga have yellowish or reddish spots.
                            The adult pompilids and their larvae feed on flowers and paralyzed spiders, respectively.
                            Females of them prey exclusively upon spiders (hence the common name, spider wasps)
                            (EVANS & YOSHIMOTO 1962). They paralyze the spiders through stinging their nerve
                            centers. Female wasp digs nest in the ground by scraping soil backward with her forelegs
                            before or after hunting (depend on species). However,  a  few  species  make  free  nests
                            above ground, usually in protected places or with thick mud walls. The hunter carries the
                            paralyzed spider in the nest and then lays an egg on the prey body. The eggs hatch and
                            the larvae feed on live, paralyzed spiders until it is time to pupate (EVANS & SHIMIZU
                            1996).
                            The pompilid fauna of Iran is not well studied and only little information is available
                            about their occurrence, distribution, taxonomic  and  biologic  status  (EBRAHIMI et al.
                            2008). ESMAILI & RASTEGAR (1974) reported four species from Damavand (in vicinity
                            of Tehran). WOLF (2003) and EBRAHIMI et al. (2008) reported nine and 43 species from
                            various parts of Iran, respectively.
                            In the present study, a faunistic survey was carried out on family Pompilidae in central
                            regions of Mazandaran province.

                                                     Material and Methods

                            Sampling area. Mazandaran province is located at north of Iran along the southern coast
                            of Caspian Sea. It is situated between 35°47′ to 36°35′N and 50°34′ to 54°10′E, which
                            ranges in altitude from 21 to 2120 m above sea level.
                            The materials were collected from different parts of Mazandaran province during 2007-
                            2008. The geographical coordinates of sampling area are given in table 1.
                            Sampling methods and instruments. Sweeping net, window traps, Malaise traps and color
                            traps were used for collecting pompilid specimens. They will be presented hereafter as
                            SN, WT, MT and CT respectively.
