Treatment

Arthrolytus gurderei nov.sp. ( Figs 1i View Fig , 3l View Fig )

T y p e m a t e r i a l s: Holotype ♀, Turkey: Tokat, Almus, side of lake, 7.v.1988, 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 Mr. Metin Gürdere who was a government minister of Turkey and made many invaluable works for Tokat, helped me during my works in Tokat.

D i a g n o s i s: ♀: Head in dorsal view 2.22x as broad as long; hardly protuberant at level of toruli; with temples 0.46x as long as eyes. OOL 1.8x POL; Malar space at least 0.39x length of an eye. Antennae inserted well above level of ventral edge of eyes, their toruli about equidistant from the anterior margin of the clypeus and the median ocellus; combined length of pedicel and flagellum almost as the breadth of the head; antenna with anelli plus F1 1.32x as long as pedicel; flagellum 2.23x length of scape; club 1.6x length of F1; pedicel 0.63x as long as anelli plus first funicle; Forewing with a faint infumate discal cloud; with marginal vein 1.94x stigmal vein and 1.37x post marginal vein; the latter 1.46x stigmal vein; angle between stigmal vein and postmarginal vein forming 35°; speculum and basal cell open; Propodeum with transverse costula, median and plicae; (medially) 0.73x as long as scutellum; its median area about 1.26 times as broad as long. Metasoma without pale spot.

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 2.43 mm. Body black, with metallic copery reflection, Metasoma without pale spot, antennal scape and pedicel and anelli yellow, flagellum dark, legs with coxae and femora fuscous, tibiae testaceous; tarsi yellow, pulvilli black.

Head in lateral view 1.83x as height as length; in frontal view 1.2x as wide as height; width of frons 2.67x as wide as width of eye; the latter 1.35x as long as width; anterior margin of clypeus entire. Antenna ( Fig. 1i View Fig ) with F1 1.8x as long as broad, distinctly constricted basally; F2 1.18x longer than broad; F3 slightly longer than broad; F4-F5 quadrate, F6 slightly transverse. Relative measurement of antenna: scape 50; pedicel 20; F1 18; F2 14; F3 13; F4-F5 11; F6 9; club 29.

Mesosoma almost 1.5x as long as width; 1.25x as long as metasoma; scutellum as long as width Forewing ( Fig. 3l View Fig ) with costal cell of fore wing 11 times as long as broad; submarginal vein 1.36x as long as marginal vein;

Metasoma 1.12 times as long as broad, 0.71x as long as head plus mesosoma, 0.94x as long as mesosoma 1.75x wider than mesoscutum.

♂: unknown.

C o m p a r a t i v e n o t e s: Arthrolytus gurderei nov.sp. is similar to Arthrolytus slovacus GRAHAM, 1969 and Arthrolytus kahvecii nov.sp. in having antennae inserted well above level of ventral edge of eyes, their toruli about equidistant from the anterior margin of the clypeus and the median ocellus; head hardly protuberant at level of toruli; head in dorsal strongly transverse, at least 2.25 times as broad as its maximum length, with temples hardly one sixth as long as eyes; pedicel 0.63-0.75x as long as anelli plus first funicle; forewing without black spot or at most with a faint infumate discal cloud. But A. gurderei differs from both of them in having malar space at least 0.39x length of an eye; head in dorsal view 2.43x as broad as long; Metasoma without pale spot (in both species malar space hardly one third length of an eye; head in dorsal view at most 2.31x as broad as long; wings slightly yellowish, with a faint infumate discal cloud).
