Chyliza qaradaghi Khaghaninia et Gharajedaghi , sp. n. ( fig. 1–11 )

T y p e - l o c a l i t y. Iran: East Azerbaijan Province, Qaradagh Forests: Qala Deresi , 38°51' N, 46°59' E, h = 1647 m a. s. l., 13:00, 6 Jun. 2011.

M a t e r i a l. Holotype ♀. Iran. East Azerbaijan province, Qaradagh Forests: Qala Deresi , 38°51' N; 46°59' E, 1647 m, 06.06.2011 (Gharajedaghi and Khaghaninia leg.) ( IMTU). 1 Ơ (partially damaged), label as in the holotype ( IMTU).

E t y m o l o g y. Named after its type locality, Qaradagh (Turkish: “black mountain”) Forests massive located in north of East Azerbaijan province in northwestern Iran 147 km northwest of Tabriz. It has the richest flora in Iran with about 775 known plant species.

D i a g n o s i s. This species is similar to C. exenuata in having arista thickened in basal third with dense black hairs and lacking anteroventral comb of black spinules in male fore tibia; hind femur with black subapical spot ( fig. 7 ). New species is characterized by the following combination of characters: head yellow (except occiput); antennal postpedicel 2 times longer than high at base; hind tibia having large lateral black area on 2/3 apical half; surstyli with straight lateral margin ( fig. 10 ), apical lobes of aedeagus rhombic, triangular to top ( fig. 11 ). In C. exenuata head completely black (except antennae); antennal postpedicel more than 2 times longer than high at base; hind tibia entirely yellow ( fig. 12 ); surstyli with concave lateral margin ( fig. 14 ), apical lobes of aedeagus rectangular with chopping straight apex ( fig. 15 ).

Eyes finely haired, high of eyes 1.6 times longer than wide. mouthparts darkish, with white setulae; palpi black. With one pair of divergent postocellar setae, one pair of convergent inner vertical setae, one pair of outer vertical setae, two pairs of orbital setae. Length: height: width ratio — 1.5/2/1 ( fig. 2, 3 ). T h o r a x: Black, with pale yellow and white pubescent; one pair of dorsocentral, one pair of acrostichal, one pair of supralar, one pairs of postalar, 3 pairs of scutellar bristles. L e g s: Mainly yellow, with fine light hairs; fore and mid legs yellow; hind leg yellow, femur with latero-dorsal black subapical spot, tibia latero-ventrally blackish in apical 2/3, hind basitarsus about equal in length to rest tarsomeres combined ( fig. 7 ). W i n g s: Evenly brownish; veins brown. Lower calypter bare (except margin, with yellow cilia). Halter mainly yellow, black in basal ( fig. 6 ). A b d o m e n: Length: 2.7 mm, blackish and shiny, mainly with black and white tomentous. Genitalia: Length of ovipositor (segments 8 to 10 and cerci) 0.8 m. Epiproct and cerci fused, length 0.25. Sternite 8 with one distinct apical setae. Epiproct and hypoproct with some short setae and 4 pairs of long hairs, length of apical pair (0.17 mm) two times longer than supapical pairs. Segment 8 without any setulae on surface ( fig. 9 ).
