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 : 299-300

Oxypoda (Thliboptera) infissa sp.n. ( Figs 121-131 )

Holotype 3: GR. Thessalia [4], Ossa Oros, NE Spilia, 1450 m, N-slope, 39°48'27N, 22°40'45E, 22.VII.2004, V. Assing / Holotypus 3 Oxypoda infissa sp. n. det. V. Assing 2006 (cAss). Paratypes: 1♀: same data as holotype (cAss) ; 2♀♀: GR. Evritania, Nr. 3, 15 km SSW Karpenisi , Mt. Kaliakouda, 1500 m, 38°48'12N, 21°46'08'E, 14.IV.2000, V. Assing (cAss) .

D e s c r i p t i o n: Habitus as in Fig. 121 . Based on external morphology, indistinguishable from O. fissa ( Figs 122-125 ).

3: sternite VIII distinctly oblong ( Fig. 126 ); median lobe of aedeagus of similar general morphology as that of O. fissa , but with internal structures of slightly different shape and with apically unincised ventral process ( Figs 128-129 ); apical lobe of paramere as in Fig. 130 .

♀: sternite VIII approximately as wide as long, its posterior margin convex ( Fig. 127 ); spermatheca similar to that of O. fissa , with rather long duct ( Fig. 131 ).

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

C o m p a r a t i v e n o t e s: The species is highly similar to and apparently the adelphotaxon of O. fissa , from which it is reliably separated only by the morphology of the median lobe of the aedeagus, especially by the apically unincised ventral process. From the only other dark Greek species of Thliboptera , O. micans , it is readily distinguished by the relatively smaller head, by the shorter and much more slender antennae, the more convex (cross-section) and more distinctly punctate pronotum, the more densely and distinctly punctate elytra, by the more oblong tergite and sternite VIII, by the completely different morphology of the aedeagus (see also Fig. 108 ), and by the longer duct of the spermatheca.

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 known only from the Ossa Oros, Thessalia, and from the Kaliakouda Oros, Evritania, Greece, where the types were sifted from litter of Abies, fern, and grass at altitudes of 1450 and 1500 m.
