Oxypoda (Thliboptera) recta sp.n. ( Figs 132-141 , Map 7 )

Holotype 3: TR - Antalya, 12-, 1230 m, N Kalkan, Dumanlı Dağı, cedar-pine forest, pasture, 36°24'01E, 29°25'53E, 5.X.2002, V. Assing / Holotypus 3 Oxypoda recta sp. n. det. V. Assing 2006 (cAss). Paratypes: 2133, 15♀♀: same data as holotype (cAss, cFel, OÖLL) ; 13: TR - Muğla, 1, N Fethiye, Çaliş , bank of stream, 10 m, 36°40N, 29°06E, 1.X.2002, V. Assing (cAss) ; 13, 1♀: TR [24] - Mersin, NW Tarsus, Çamlıyayla , 37°08'51N, 34°37'16E, 1190 m, 23./ 24.IV.2005, Brachat & Meybohm (cAss) ; 13, 1♀: TR - Mersin [31], Findikpinari , 1090 m, 36°54'46N, 34°22'55E, 1. V.2004, leg. C. Besuchet (cAss) ; 13, 1♀: Turkey: Anatolia mer., Mersin: Arsanli , 15 km NW Erdemli, 11.-19. V.1994, leg. Hauck (cSch, cAss) .

D e s c r i p t i o n: 3.7-4.6 mm; external morphology as in O. fissa ( Figs 132-134 ).

3: sternite VIII distinctly oblong, its posterior margin strongly convex ( Fig. 135 ); median lobe of aedeagus very distinctive, in lateral view with long, straight, and acute ventral process and with characteristic internal structures ( Figs 137-138 ); apical lobe of paramere as in Fig. 139 .

♀: sternite VIII oblong, its posterior margin convex ( Fig. 136 ); spermatheca with rather long duct ( Figs 140-141 ).

E t y m o l o g y: The name (Lat., adj.: straight) refers to the shape of the ventral process of the aedeagus.

C o m p a r a t i v e n o t e s: Fromthehighlysimilar O. fissa , this species is reliably distinguished only by the morphology of the median lobe of the aedeagus, especially the shape of the ventral process. Oxypoda antennata , whose aedeagus shows a faint resemblance to that of O. recta , is distinctly larger and has much longer antennae.

D i s t r i b u t i o n a n d b i o n o m i c s: The known distribution ranges from Muğla in the West to Mersin in the east ( Map 7 ). In the locality where the holotype was found, altogether 37 specimens were sifted from the litter of a mixed cedar and pine forest. The altitudes range from 10 to 1230 m. Two specimens collected in April are teneral.
