Assing, V., 2006, On some species of Oxypoda MANNERHEIM from Turkey and adjacent regions (Insecta: Coleoptera: Staphylinidae Aleocharinae), Linzer biologische Beiträge 38 (1), pp. 277-331 : 298

Oxypoda (Thliboptera) acutissima sp.n. ( Figs 104-107 , Map 6 )

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 (cAss) / Holotypus 3 Oxypoda acutissima sp. n. det. V. Assing 2006 (cAss).

D e s c r i p t i o n: Based on external characters indistinguishable from O. micantoides and O. gladiatoria .

3: sternite VIII transverse, its posterior margin broadly and rather weakly convex; median lobe of aedeagus somewhat resembling that of O. gladiatoria , very large, with very acute ventral process (especially in lateral view), with pronounced crista apicalis, and with long two pairs of distinctly sclerotised structures in the internal sac ( Figs 104-106 ); apical lobe of paramere as in Fig. 107 .

♀: unknown

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

C o m p a r a t i v e n o t e s: From the highly similar O. micantoides and O. gladiatoria , this species is reliably distinguished only by the morphology of the aedeagus, especially the shape of the long and very acute ventral process.

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 is currently known only from one locality, the Dumanlı Dağı in the southwest of Antalya province ( Map 6 ), where the holotype was found in a mixed pine and cedar forest at an altitude of approximately 1200 m, together with numerous specimens of O. recta (see below).
