Pakistan J. Zool., vol. 45(5), pp. 1279-1284, 2013 New Records and a Key to the Species of Genus Hockeria Walker (Hymenoptera: Chalcididae) from Khyber Pakhtunkhwa, Pakistan Toheed Iqbal*, Mian Inayatullah and Sajjad Ahmed Department of Entomology, Faculty of Crop Protection Sciences, The University of Agriculture, Peshawar, Pakistan. Abstract.- Three newly recorded species of Hockeria (Chalcididae), Hockeria nikolskayae, Hockeria anupama and Hockeria manii, are described. An identification key to the species of Pakistan is also provided along with illustrations of important features. Keywords: Chalcididae, Hymenoptera, Hockeria. INTRODUCTION Hockeria was erected by Walker (1834) based on the type species Chalcis bispinosa Fabricius sensu Kirby (Hockeria bifasciata Walker) (Narendran and Sudheer, 2005). As a member of the subfamily Haltichellinae, the genus has the postmarginal vein relatively longer and in some Hockeria, a slightly concave frons, and the vertex is thin in some species. A distinguishing feature of this genus is the presence of variable carinae on the basal tergite of the gaster, and species may have two or three short longitudunal carinae (Narendran, 1989). In some cases the gaster may be ecarinate or polycarinate. Morphologically, Hockeria and Antrocephalus are extremely close and it is often difficult to distinguish between the two genera. In some Hockeria (lankana and bangalorica), postmarginal vein is relatively long and in some Hockeria frons is slightly concave (bangalorica). The vertex is extremely thin in some species of Hockeria. The carinae present on gaster is variable in this genus (Narendran, 1989). Species of Hockeria are mostly parasitic on Lepidoptera (Narendran, 1989). Hockeria has a worldwide distribution, with 66 species of genus Hockeria reported from the Oriental region (Narendran, 1989; Noyes, 2011). The current study outlines three new species of Hockeria from Khyber Pakhtunkhwa. Hockeria tamaricis Boucek has been reported from Pakistan (Boucek, 1982; Narendran, 1986), but ________________________ * Corresponding author: Toheed.Iqbal@aup.edu.pk 0030-9923/2013/0005-1279 $ 8.00/0 Copyright 2013 Zoological Society of Pakistan the exact location of the species is unknown from where the species was reported. The present study adds three more species to this genus, known from Pakistan. MATERIALS AND METHODS This study was based on specimens collected from different ecological zones in the northern and plain areas of Khyber Pakhtunkhwa. The main areas of collection were Peshawar, Mardan, Swabi, Gilgit, D. I. Khan, Swat, Chitral and Hazara Division. Collected specimens were preserved in 70% alcohol and then transferred to 97 % alcohol for 5 hours before being mounted on a card point. Morphological terms follow Gibson et al. (1997). Terminology of surface sculpture was from Harris (1979). The synonymy, diagnostic characters and material examined are provided for each species. All material is deposited in the insect museum, Department of Entomology, The University of Agriculture, Peshawar. Genus HOCKERIA Walker, 1834 Key to species of Hockeria in Pakistan 1.
