T y p e m a t e r i a l s: Holotype ♂, Turkey: Erzurum, 04.vi. 1982. Leg. M. Doğanlar, deposited in Insect Museum of Biological Control Station, Yüreğir, Adana, Turkey (IMBC). Paratypes: 2♂ ♂, same data as the holotype.

D i a g n o s i s: ♂: Anterior margin of clypeus entire; antenna with combined length of pedicel and flagellum almost 1.5x as long as breadth of the head; pedicel 1.5x as long as wide and 0.5x as long as F1; flagellum 4.68x length of scape, filiform; funicular segments as wide as pedicel, almost in same width; F1 2.6x as long as broad; F2 2.14x as long as width; F6 1.67x as long as wide; club 3.66x as long as broad, about as long as 2 preceding funicular segments; forewing with a cloud, slightly darker below stigmal vein; post marginal vein 1.14x marginal vein and 1.41x stigmal veins; marginal vein 1.23x stigmal vein, 0.88x postmarginal vein. Propodeum with median area 1.66x as wide as long, with broad fovea basaly; without transverse costula, plicae and median carina; antenna with pedicel yellow. Metasoma with a yellow band on second and third tergite.

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 2.5 mm long. body black with bluish metallic reflection, legs with coxae concolorous with body; femora, tibiae and tarsi yellow, except pretarsi brown; antenna with scape, pedicel and anelli yellow, flagellum black.

Head in lateral view (36:22) 1.64x as height as length; in anterior view (47:36) 1.3x as wide as height; in dorsal view (47: 22) 1.24x wider than mesoscutum (38); wide of frons 28; length of eye 24; lower margin of clypeus entire in the middle; POL: OOL 12: 7; eye long oval 24:17, malar space (8) 0.33x eye length; Antennal formula 11263. Antenna ( Fig. 2j ) with scape (25), basally narrow, slightly expanded in its upper half, the subapical shiny boss tending to be indistinct; combined length of pedicel and flagellum (117), pedicel (9:6) 1.5x as long as width and 0.5x as long as F1; flagellum (104), filiform; F1 (18:7); F2 (15:7); F3 (14); F4 (13); F5 (12); F6 (10:6) 1.67x as long as width; club (22), 3 segmented, acuminate, long 1.22x as long as F1. Linear sensillae on F1 5, in 2 rows, in apical half; F2 5, F3-F6 3, in one row, in apical half; C1 2; C2 1; C3 1.

Scutellum (with axillullae) (17:15) 1.13x as long as width; Forewing ( Fig. 3r ) with stigmal vein forming 30° angle to the postmarginal vein; stigmal vein thin, long with a broad knob; costal cell 13 times as long as broad; basal cell with some hairs distally, basal vein distinct, speculum open; marginal vein distinctly enlarged, measurements of m: pm: st as 21: 24: 17; Propodeum about 0.4x length of scutellum; median area 0.66x as wide as long (20:12).

Metasoma 0.86x as long as mesosoma, about twice as long as width.

♀: unknown.

B i o l o g y: unknown.

D i a g n o s i s: Arthrolytus nenehatunae nov.sp. is similar to Arthrolytus slovacus Graham 1969 in having anterior margin of clypeus entire or slightly immargined; Antenna with combined length of pedicel and flagellum almost 1.5x as long as breadth of the head; club 3.66x as long as broad. But it differs from A. slovacus in having forewing with a cloud, slightly darker below stigmal vein; post marginal vein 1.14x marginal vein and 1.41x stigmal veins; marginal vein 1.23x stigmal vein, 0.88x postmarginal vein; propodeum with median area 1.66x as wide as long, with broad fovea basaly; without transverse costula, plicae and median carina; antenna with pedicel yellow (in A. slovacus forewing immaculate; marginal vein about 1.8 times as long as the stigmal vein, and slightly longer than the postmarginal vein; median area of propodeum only about 1.5 times as wide as long, reticulate, with complete plicae; antenna with pedicel brown).
