Arthrolytus geyrazensis nov.sp. ( Figs 2h View Fig , 3p View Fig )
T y p e m a t e r i a l s: Holotype ♂, Turkey: Tokat, Geyraz, 01.vi.1989, Leg. H. Çam, deposited in Insect Museum of Biological Control Station, Yüreğir, Adana, Turkey (IMBC). Paratype: 1♂, same data as the holotype.
E t y m o l o g y: The name is derived from the name of Geyraz, Tokat, from which the holotype was collected.
D i a g n o s i s: ♂: Antenna with scape as long as F1; pedicel 1.25x as long as wide and 0.3x as long as F1; flagellum 6.35x length of scape; F7 as long as wide; club 0.88x as long as F1; linear sensillae on F1 absent; F2 1; F3 2; F4-F6 3; F7 2; C1 3; C2 1. Head in lateral view 1.6x as long as width; 1.3x wider than mesoscutum; in anterior view wide of frons 1.87x width of eye; lower margin of clypeus slightly emarginated in the middle; eye 1.33x as long as width; Scutellum slightly transverse 1.11x as wide as long; propodeum with costula distinct, median carina absent, plicae developed. Fore wing with stigmal vein forming 50° angle to the postmarginal vein; with speculum narrow, narrowly opened; basal vein distinct, with hair line; basal cell with some hairs; postmarginal vein about 0.6x as long as the marginal vein; 1.27x as long as stigmal vein; marginal vein 2.1x as long as stigmal vein. Legs fuscous with metallic reflexion, except tips of femora, tibiae and tarsi yellow.
D e s c r i p t i o n: The diagnostic characters of this species are given above and need not be repeated here. Some additional characters are the following:
♂: Body 2.2 mm long. Body black with bluish metallic reflection, Metasoma basally on second tergit with pale band; legs fuscous with metallic reflexion, excepts trochanters, tips of femora, tibiae and tarsi yellow, forewing hyaline, veins pale brown; metasoma on the second tergit with pale band.
Head in lateral view (27:17) 1.6x as long as width; in anterior view (32:41) 1.28x as wide as hight; in dorsal view (43: 18) 2.4x as wide as long 1.3x wider than mesoscutum (33); wide of frons (28) 1.87x width of eye length of eye 20; lower margin of clypeus slightly emarginated in the middle; POL 2x OOL; eye long oval (20:15) 1.33x as long as width;, malar space (8) 0.4x eye length. Antennae ( Fig. 2h View Fig ) with 7 funicular segments and a 2-segmented clava, with scape in anterior view its anterior margin slightly convex, posterior margin almost straight, hardly expanded in its upper half, the subapical shiny boss tending to be indistinct Antenna with scape (17) as long as F1; in anterior view scape hardly expanded in its upper half, the subapical shiny boss tending to be indistinct, posterior margin almost straight; pedicel (5) 1.25x as long as wide and 0.3x as long as F1; flagellum (108) 6.35x length of scape, filiform; funicular segments gradually decreasing in length, F1 17, F2 15; F3 13; F4 12; F5 11; F6 10; F7 (8) as long as wide; club (15) 2 segmented, acuminate, short, 0.88x as long as F1; linear sensillae on F1 absent; F2 1; F3 2; F4-F6 3; F7 2; C1 3; C2 1.
Mesosoma slightly narrower than head (22:25) 1.6x as long as width; Scutellum slightly transverse (with axillullae 20:18) 1.11x as wide as long; Forewing ( Fig. 3p View Fig ) with stigmal vein forming 50° angle to the postmarginal vein; costal cell 10 times as long as broad; speculum narrow, narrowly opened; basal vein distinct, with hair line; basal cell with some hairs; marginal vein slightly enlarged, stigmal vein thin, long with a broad knop; measurements of m:pm:st as 23: 14: 11; pm about 0.6x as long as the marginal vein; 1.27x as long as stigmal vein; marginal vein 2.1x as long as stigmal vein. Propodeum finely reticulate medially; length of propodeum medially inferior to 0.4x length of scutellum; median area 1.72x as wide as long (31:18) costula distinct, median carina absent, plicae distinctly developed.
Metasoma 0.75x as long as mesosoma; about twice as long as width.
♀: unknown
C o m p a r a t i v e n o t e s: Arthrolytus geyrazensis nov.sp. is similar to A. discoideus ( NEES, 1834) in having fore wing with marginal ciliae; antennae with 7 funicular segments and a 2-segmented clava, with scape in anterior view its anterior margin slightly convex, posterior margin almost straight, hardly expanded in its upper half, the subapical shiny boss tending to be indistinct. But it differs from A.discoideus in having Antenna with pedicel 1.25x as long as wide; F7 as long as wide; linear sensillae on F1 absent; F2 1; F3 2; F4-F6 3; F7 2; C1 3; C2 1. Head in dorsal view 1.3x wider than mesoscutum; propodeum without median carina; Fore wing with stigmal vein forming 50° angle to the postmarginal vein; marginal vein 2.1x as long as stigmal vein (in A.discoideus antenna with pedicel 0.8x as long as wide; F7 2.5-2.62x as long as wide; linear sensillae on F1 2; F2 3; F3 3; F4-F7 4, C1 3; C2 1; head in dorsal view 1.15x wider than mesoscutum; propodeum with median carina; Forewing with stigmal vein forming 40°angle to the postmarginal vein; marginal vein 1.44x as long as stigmal vein).
