Rédei, D.: A new species of Stirogaster from Iran (Heteroptera: Reduviidae: Stenopodainae)

localities, most of them occurring in the Middle East, which must be the centre of the dispersion of the genus. The only species, which is known to occur only in the Afrotropical Region (Sudan), is S. ruttledgei. Four species, namely S. fausti, S. desertorum, S. uvarovi and S. laticeps have hitherto been reported from Iran. Recent collecting trips to Iran by Hungarian entomologists also yielded numerous assassin bugs. While identifying the material deposited in the Hemiptera Collection of the Hungarian Natural History Museum (HNHM), Budapest, a remarkable specimen of Stirogaster has been found. Since it differs essentially from the known species, it is described as new in this paper. Stirogaster ahriman sp. n. (Figs 1-16) Type material - Holotype (male): "IRAN, prov. Fars / Mts. Ktihha-ye Zagros" (printed), "Safe Abad / 23. VI. 2000. / leg. Gy. Ro/.ner" (printed), "HOLOTYPE / Stirogaster / ahriman sp. n. / det. D. Rédei, 2004" (type label with red borders, handwritten + printed); deposited in the HNHM. Description - Macropterous male.

Colour: General colour stramineous with dark pattern on head and fore wings. Head black, a pair of inconspicuous spots anterolaterad to ocelli yellowish; antennái tubercles, a pair of spines between antennái insertions, clypeus, labrum, bucculae and dorsal side of jugae rather uniformly stramineous. Antenna! joints rather uniformly stramineous. Ventral side of labium stramineous, dorsal side brown, gradually lightening towards apex. Pronotum stramineous, posterior border of fore lobe with four small brownish spots, hind lobe with an anteromedial longitudinal brownish spot, posterior border of hind lobe inconspicuously brownish. Scutellum dark brown, apical prolongation lightened apically. Coriaceous anterior portion of fore wings light stramineous, slightly translucent, clavus with a wide, elongate, brownish spot along its medial border, corium hardly perceptibly darkened between Cu and claval suture, veins light stramineous, extreme apex of PCu+lA with an apparent fulvous spot. Membrane whitish, translucent, an elongated basal spot mediad to PCu as well as most part of apical cells (except their borders along veins and a greater basolateral spot in external cell) greyish brown; veins PCu and Cu greyish, M stramineous, each with a fulvous spot basally.
