description: Arthrolytus magarsosensis nov.sp. (Figs 1e, 3g)
T y p e m a t e r i a l s: Holotype ♀, Turkey: Adana, Karataş, 8.viii.1984, deposited in Insect Museum of Biological Control Station, Yüreğir, Adana, Turkey (IMBC).
E t y m o l o g y: The name is derived from the name of Magarsos, ancient city in the 7th century B.C, in Karataş, Adana.
D i a g n o s i s: ♀: Right mandible with 4 teeth, left mandible with 3 teeth; Malar space 0.37x eye length; forewing with post marginal vein about 1.5x as long as the marginal vein. Head in anterior view 1.4x as wide as long; POL 1.33 OOL; malar space 0.37x length of eye. Antenna with flagellum 2.28x length of scape; F6 almost transverse; club 1.5x as long as F1. Scutellum slightly transverse (with axillullae) 1.16x as wide as long; propodeum finely reticulate, with some fovea basally; length of propodeum medially 1/3 length of scutellum; median carina slightly developed, plicae absent.
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 3.0 mm long. Body black with metallic blue reflection; legs with coxae concolorous with body, femora fuscous, tibiae and tarsi yellow; scape, pedicel and anelli yellow, flagellum brown. Forewing medially pale brown, fuscous cloud of fore wing relatively narrower and less intense, often not reaching the hind margin of the wing.
Head in lateral view parallel sided, 1.4x as wide as long (50:35); in anterior view transversally oval, 1.4x as wide as long (70:50); head in dorsal view 65: 30, slightly wider than mesoscutum (57); wide of frons 45; length of eye 35; lower margin of clypeus slightly emarginated in the middle; POL 1.33x OOL; eye long oval 35:22, malar space (13) 0.37x eye; Antenna inserted low, slightly above level of ventral edge of eyes. Flagellum 2.28x length of scape; club acuminate, short, 1.5x as long as F1. Antenna (Fig. 1e) with scape 43, in anterior view its anterior margin slightly convex, posterior margin almost straight; pedicel 15, almost twice as long as wide and as long as F1; flagellum 98, 2.28x length of scape, filiform; funicular segments gradually decreasing in length, F1 15, F6 10x as long as wide; club acuminate, short, 1.5x as long as F1.
Mesosoma (41) as wide as head, 1.4x as long as width; as wide as metasoma. Scutellum slightly transverse (with axillullae 35:30), frenal carina distinct laterally; Forewing (Fig. 3g) with stigmal vein forming 35° angle to the postmarginal vein; marginal vein slightly enlarged, stigmal vein relatively long with a broad knop; measurements of m:pm:st as 37: 55: 42; post marginal vein about 1.5x as long as the marginal vein, 1.3x as long as stigmal vein; marginal vein 0.9x.as long as stigmal vein. Propodeum finely reticulate, with some fovea basally; length of propodeum medially inferior to 1/3 length of scutellum; median carina slightly developed, plicae absent.
Metasoma (53) 1.3x as long as length of mesosoma. ♂: unknown.
C o m p a r a t i v e n o t e s: In the subgenus Anarthrolytus, Arthrolytus magarsosensis nov.sp. is similar to A. nanus ASKEW & NIEVES ALDREY, 1982 and A. glandium BOUCEK, 1967 in having forewing with stigmal vein forming at least 35 o angle with the postmarginal vein. But it differs from A. nanus in having forewing with stigmal vein forming 35°angle to the postmarginal vein; malar space 0.37x eye length and legs with coxae and femora dark bluish-green (in A. nanus forewing with stigmal vein forming 40°angle to the postmarginal vein; malar space about 0.33x eye length and Legs stramineous to whitish). A. magarsosensis nov.sp. also differs from A. glandium in having malar space 0.37x eye length; forewing with post marginal vein about 1.5x as long as the marginal vein; POL 1.33 OOL; antenna with flagellum 2.28x length of scape; club 1.5x as long as F1 and other characters given in the key (in A. glandium malar space 0.44x eye length; forewing with post marginal vein almost as long as marginal vein; POL 1.7 OOL; antenna with flagellum 1.65x length of scape; club hardly longer than F1).
