Oxypoda (Thliboptera) ormana FAGEL 1971 ( Figs 157-162 )

Oxypoda (Sphenoma) ormana FAGEL 1971: 139 ff.

Material examined: Turkey: Bursa: 13, 2♀♀. Uludağ, 1900-2000 m, 12. V.1976, leg. Besuchet & Löbl ( MHNG, cAss).

D i a g n o s i s: Species of intermediate size., 4.0- 4.6 mm. Coloration: head and abdomen dark brown to blackish brown, with the margins of the abdominal segments and the apex of the abdomen paler; legs reddish brown; antennae brown, with the basal antennomeres paler.

Pronotum strongly convex in cross-section, rather large in relation to head, approximately 1.6 times as wide as head and 1.25 times as wide as long; puncturation fine and very dense.

Elytra rather short, at suture approximately 0.75 times as long as elytra; puncturation very dense and somewhat asperate; surface almost matt. Hind wings of reduced length. Metatarsomere I about as long as the combined length of II-IV.

Abdomen with dense and distinct puncturation; puncturation of tergite VII distinctly sparser than that of tergites III-V; posterior margin of tergite VII with palisade fringe; tergite VIII not distinctly transverse, its posterior margin in the middle weakly concave.

3: sternite VIII approximately 1.15 times as long as wide, its posterior margin strongly convex ( Fig. 157 ); median lobe of aedeagus with strongly bent ventral process in lateral view ( Figs 159-160 ); apical lobe of paramere moderately long, basally somewhat dilated, and with relatively long apical seta ( Fig. 161 ).

♀: sternite VIII approximately as long as wide, its posterior margin weakly convex ( Fig. 158 ); spermatheca as in Fig. 162.

C o m p a r a t i v e n o t e s: The species is distinguished from other consubgeners occurring in Turkey especially by the morphology of the aedeagus. It is also characterised by the distinctly convex and relatively long pronotum (somewhat resembling that of O. togata ), by the dense puncturation of the forebody, by the reduced hind wings, by the rather short and not very massive antennae, and by the strongly convex posterior margin of the male sternite VIII.

C o m m e n t s: The original description of this species is based on a single holotype specimen from the Uludağ, where it was collected at an altitude of 1800-1900 m. The holotype was not seen, but considering that the above material was collected at or in the immediate vicinity of the type locality and that it is in good agreement with the morphological characters indicated in the original description, there is little doubt that the present interpretation is accurate.

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 species has become known only from the Uludağ, Bursa, where it was collected at an altitude of 1800-1900 m ( FAGEL 1971).
