T y p e m a t e r i a l s: Holotype ♂, Canada: Ontario, Dundas, 28.vi.1955, O. Peck, deposited in the CNC. Paratype: ♂, same data as holotype.
E t y m o l o g y: The name is derived from the name of Dr. Oswald Peck who collected the types.
D i a g n o s i s: Malar space 0.19-0.22x eye length; combined length of pedicel plus flagellum 1.37x as long as breadth of head; Antenna: scape basally narrow, slightly expanded medially; pedicel 1.54x as long as wide and 0.5x as long as F1; flagellum 3.14x length of scape; F1 2x; F2-F4 1.3x; F5 1.05; F6 quadrate; club 2.4x as long as broad, as wide as F6,1.2x as long as F1; linear sensillae on F1 4; F2 6 in two rows; F3-F6 3-4, in one row apically; C1 3; C2 3; C3 2;. Forewing with stigmal vein forming 40° angle to the postmarginal vein; with a faint cloud slightly darker around stigmal vein; costal cell 8.67 times as long as broad; post marginal vein 1.21x marginal vein and 1.7x stigmal vein; marginal vein 1.4x stigmal vein; speculum narrowly open; Propodeum about 0.54x length of scutellum, median area finely reticulated; with transverse costula, plicae and median carina; median area 1.37x as wide as long body black with bluish metallic reflection; legs with coxae concolorous with body; femora fuscous, tibiae and tarsi yellow. Propodeum about 0.54x length of scutellum, median area finely reticulated; with transverse costula, plicae and median carina; median area 1.37x as wide as long with broad metasoma pale band basally; 0.9x as long as mesonotum.
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 2.1 mm long. body black with bluish metallic reflection, Metasoma black, basally with yellow band; antenna with scape pale yellow, pedicel and anelli fuscous, funicular segments and club black legs with coxae, concolorous with body; femora testa-
ceous, tibiae and tarsi yellow; forewing with a faint cloud slightly darker around stigmal vein.
Head in lateral view 37:18; in anterior view 47:37, almost as wide as height; in dorsal view 48: 18, 1.37x wider than mesoscutum (35); wide of frons 29; lower margin of clypeus entire in the middle; POL: OOL 13: 9; eye long oval 28:15, malar space 6. Malar space 0.37x eye length. Antenna ( Fig. 2b View Fig ) with combined length of pedicel and flagellum (110), almost 1.27x as long as breadth of the head; flagellum 3.12x length of scape, club about 2.7 times as long as broad, about as long as 2.2 of the preceding funicular segments; F1 1.9x as long as broad, the sixth almost quadrate; scape 32, basally slightly narrow, slightly expanded medially; pedicel 9:5, 1.8x as long as wide and 0.53x as long as F1; flagellum 100; flagellum filiform, funicular segments distinctly wider than pedicel, almost in same width, gradually shortening towards tip, F1 distinctly constricted basally, 17:9, F2 12:9; F3-F4 11:9; F5-F6 9:9, quadrate; club 23:8.5, 3 segmented, acuminate, long, 1.35x as long as F1, 2.7x as long as broad, 0.76x as long as 3 preceding segments; linear sensillae on flagellar segment placed apically in a row, F1-F2 with 4, F3-F6 4-5; in apical half, C1 5; C2 5; C3 3. Scutellum almost as long as width (with axillullae) 18:17; Forewing ( Fig. 3b View Fig ) with stigmal vein forming 50° angle to the postmarginal vein; stigmal vein thin, long with a broad knob; costal cell 8.64 times as long as broad; post marginal vein 1.1x marginal vein and 1.4x stigmal veins; basal cell with 4-5 hairs distally, basal vein slightly indicated, speculum open; marginal vein distinctly enlarged, measurements of m: pm: st as 38: 42: 30; Propodeum with median area (20:12) at least 0.66x length of scutellum; transverse costula, plicae and median carina distinctly developed..

C o m p a r a t i v e n o t e s: The new species similar to ♂ of Arthrolytus oezbeki DOĞANLAR, 1978 in having the both mandible with 3 tooth (2 teeth sharp and one tooth entire) and antenna with F1 distinctly constricted basally; distinctly wider than pedicel (at least 1.7x), combined length of pedicel plus flagellum almost 1.4x as long as breadth of head, but it differs from the ♂ of A. oezbeki in having malar space 0.19-0.22x eye length; forewing with stigmal vein forming 40° angle to the postmarginal vein; propodeum about 0.54x length of scutellum, median area finely reticulated; with transverse costula, plicae and median carina; median area 1.37x as wide as long; body black with bluish metallic reflection; legs with coxae concolorous with body; femora fuscous, tibiae and tarsi yellow; metasoma with a pale band basally (in A. oezbeki malar space more than half length of an eye; forewing with angle between stigmal and post marginal veins 320; propodeum about 0.4x length of scutellum, median area punctured-reticulated; costula slightly indicated, plicae distinct posteriorly; median carina complete, broken medially; median area 2.5x as wide as long; body metallic green with golden reflection; femora testaceous; metasoma black).
