SCOLIIDAE FROM THE WESTERN REGION OF SAUDI ARABIA (HYMENOPTERA: ACULEATA) Neveen S. Gadallah Department of Entomology, Faculty of Science, Cairo University ABSTRACT A simplified key to the hairy wasps (Scoliidae) from the western region of Saudi Arabia is given. The key isfollowed by an annotated list that provides synonyms, and distribution. Eight species from which Micromeriella hyalina hyalina (Klug) and Scolia (Scolia) flaviceps quettaensis (Cameron) are considered as first record to the fauna of Saudi Arabia. A new species, Scolia arabica, is described.

Key words: Hymenoptera, Scoliidae, taxonomy, new species, Saudi Arabia. INTRODUTION Scoliidae, the hairy wasps, are important ectoparasitic group. Their hosts are scarabaeid larvae (Coleoptera) which are pests of forests and agriculture (Krombein, 1978; Gupta and Jonathan, 2003), and rarely curculionids (Brothers and Finnamore,1993). Members of this family are world-wide in distribution but predominantly tropical, and are of about 560 species in two subfamilies: Proscoliinae, and Scoliinae (Brothers and Finnamore,1993; Gupta and Jonathan, 2003). Members of this family are distinguished from other aculeate Hymenoptera by the presence of a flat plate formed by meso- and metasternum overlapping the bases of mid and hind coxae; the wings have dense fine longitudinal wrinkles near the apex (Krombein, 1978; Brothers and Finnamore, 1993). Black is the predominant colour, sometimes marked with bright yellow, white, red or orange markings or bands. Their wings may give off some bluish to purple iridescence. They range in length from 5-50 mm. The body vestiture is either black, white, or reddish to orange in colour. Knowledge about these wasps is still very limited. Major studies concerning the Scoliidae in different areas adjacent to the Arabian Peninsula are those by Betrem (1927, 1928, 1935, 1941) on the Indo-Australian, Western Palearctic, Chinese, and Japanese Scoliidae, respectively; Bradley (1959) on some African groups of Scoliini; Betrem and Bradley (1972) on the African Campsomerinae ; Chhotani and Ray (1975) on the Scoliidae of Rajastan and India; Jonathan (1976) who added records of Campsomerinae to the Indian fauna; Gupta (1977, 1994, 1995), and Gupta and Jonathan (1989,2003) on the Indian Scoliidae; Krombein (1978) on the Scoliidae of Sri Lanka; Jonathan and Gupta (1999a,b, 2000) on those of west Bengal, Meghalaya and Sikkim; Chahartagi (2002) on some scoliids of Tehran; Osten (2000, 2002) on the Scoliidae of the Mediterranean region and Israel; and Osten et al. (2003) on Scoliidae of Iran. No definite studies has been done concerning the Scoliidae of the Arabian Peninsula except for a recent study on Scoliidae of Oman (Osten, in press). Osten recorded five species from which he considered Micromeriella hyalina hyalina (Klug) as a first record to the Arabian Peninsula. The present work was accomplished to collect and identify the hairy solitary scoliid wasps from the Western Region of Saudi Arabia. Construction of a simplified key and an annotated checklist was aimed. MATERIALS AND METHODS Regular survey to the adult hairy solitary scoliid wasps were undertaken during the time period 2002 − 2004, covering various areas in the Western Region of Saudi Arabia (including Jeddah, Hadasham, Taif). Insects were collected by use of Japanese net and Malaise trap. The identified specimens were confirmed by Till Osten (Staatliches Museum für Naturkunde Stuttgart, Germany). Drawings were made using a camera lucida.
