Head in lateral view 1.82x as height as long; eye long oval 1.5x as long as width; POL 1.9x OOL; Forewing with stigmal vein forming 40° angle to the postmarginal vein; the latter 0.87x marginal vein and 1.33x stigmal veins; marginal vein 1.53x stigmal vein; basal cell bare, basal vein hairy; speculum narrowly open. Propodeum with median area about 0.47x length of scutellum; costula slightly indicated, median carina absent, plicae in basal half distinctly developed. Legs brown with metallic reflexion except tips of femora, tibiae and tarsi testaceous. Metasoma 2.6x as long as width; almost as long as mesosoma; basally without pale spot

Mesosoma 1.72x as long as width; slightly narrower thn width of head; scutellum almost as long as width (with axillullae) 23:24; Forewing with stigmal vein forming 40° angle to the postmarginal vein; stigmal vein thin, long with a broad knob; costal cell 8.8 times as long as broad; Forewing ( Fig. 3s ) with post marginal vein slightly shorter than marginal (20:23) and 1.33x stigmal veins; basal cell bare, basal vein hairy speculum narrowly open; marginal vein slightly enlarged, measurements of m:pm:st as 23: 20: 15.

Metasoma 2.1x as long as width, almost as long as mesosoma.

♀: unknown.

C o m p a r a t i v e n o t e s: The new species similar to ♂ of Arthrolytus yazicioglui nov.sp. in having antennal formula 11263 and club at most 2.94 times as long as broad, but it differs from A. yazicioglui nov.sp. in having antenna with combined length of pedicellus and flagellum as long as the breadth of the head; flagellum 3.2x length of scape, F2 1.37x, F3-F4 1.11x as long as width; club about 2.94 times as long as broad; POL 1.9x OOL (in A. yazicioglui nov.sp. antenna with combined length of pedicellus and flagellum 1.26 times the breadth of the head; flagellum 4.25x length of scape; F2 1.63x; F3-F4 1.43x as long as width; club about 2.67 times as long as broad; femora testaceous, tibiae and tarsi yellow; POL 1.43x OOL), and some more characters given in the key.
