R e d e s c r i p t i o n: Rather large species, 4.7-6.2 mm. Habitus as in Fig. 10 . Coloration variable: head dark blackish brown to blackish; pronotum castaneous to black; elytra reddish to blackish brown; abdomen dark brown to black, with the margins of the segments often paler; legs reddish yellow to light brown; antennae brown to dark brown, with the basal 3-4 antennomeres paler.

Head with distinct microsculpture and with relatively dense and fine, but distinct puncturation; eyes moderately large, approximately as long as postocular region in dorsal view ( Fig. 11 ); antennae slender, all antennomeres oblong ( Fig. 12 ); penultimate joint of maxillary palpus approximately three times as long as wide.

Pronotum relatively large and moderately transverse; puncturation slightly finer and denser than that of head; microsculpture shallower than that of head ( Fig. 11 ). Elytra at suture approximately 0.8 times as long as pronotum (brachypterous morph) or approximately 0.9 times as long as pronotum (macropterous morph); puncturation dense and slightly asperate. Hind wings dimorphic; either of reduced length, weakly projecting from under elytral hind margins ( Fig. 11 ), or fully developed. Legs slender; metatarsomere I approximately as long as combined length of metatarsomeres II-IV or even slightly longer. Abdomen widest at segments III/IV, slightly tapering posteriad; puncturation and pubescence very fine and dense; microsculpture indistinct or absent, interstices shining; posterior margin of tergite VII with narrow palisade fringe.

3: tergite VIII approximately 1.15-1.20 times as long as wide, its posterior margin weakly concave in the middle; sternite VIII 1.10-1.15 times as long as wide, its posterior margin broadly convex ( Fig. 13 ); median lobe of aedeagus as in Fig. 15 .

♀: posterior margin of sternite VIII truncate; spermatheca as in Fig. 16.

C o m p a r a t i v e n o t e s: From other Turkish species of Thliboptera , O. antennata is distinguished especially by the long antennae, its large size, its wing dimorphism, and the sexual characters, particularly the median lobe of the aedeagus and its subapical internal structures.

C o m m e n t s: In the original description of O. lindbergi , which is based on a single holotype male, SCHEERPELTZ (1958) erroneously attributed the species to the subgenus Oxypoda MANNERHEIM , suggesting a closer relationship to O. lividipennis MANNERHEIM - now a synonym of O. acuminata (STEPHENS) - and O. longipes MULSANT & REY.

An examination of the type material of both O. lindbergi and O. mysica revealed that they are doubtlessly conspecific. According to ZERCHE (in prep.), who studied type material both of O. antennata and of O. mysica , the latter is a junior synonym of the former. Consequently, both O. mysica and O. lindbergi are here placed in the synonymy of the senior name O. antennata .

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 speciesisapparently rather widespread in Turkey ( Map 5 ). It has been collected in the Uludağ and the Abant Dağı in northwestern Anatolia ( FAGEL 1971 ), as well as in various localities in southern Turkey (Antalya, Mersin, Adana, Kahramanmaraş) ; queries aiming at an identification of the type locality of O. lindbergi (" Chamounis ") were unsuccessful, but it should be situated in the Van lake area, since it was collected one day before Lindberg was in Van on the eastern shore of lake Van ( SCHEERPELTZ 1958). Most , if not all of the examined specimens were sifted from forest leaf litter ; the altitudes range from 1150 to 1900 m.
