( Figs 26-32 ) T y p e m a t e r i a l: Holotype : "TR [8], Burdur , W Çeltikçi Geç., 21 km SE Burdur , 37°33'37''N , 30°23'49''E , 1419 m , Zypr., Eichen, 16.II.2011 , M. Schülke / Holotypus Geostiba burdurica sp. n. det. V. Assing 2011" (cAss). Paratypes : 6, 5: same data as holotype (cSch, cAss). D e s c r i p t i o n: Body length 2.2-3.1 mm . Coloration: head dark-brown to blackish; pronotum and elytra reddish, distinctly contrasting with the head; abdomen reddishbrown, with segments VI-VII or V-VII more or less extensively infuscate; legs yellowish; antennae reddish to brown, with the basal antennomeres pale-reddish. Head approximately as wide as long; punctation sparse and extremely fine, barely noticeable; interstices with shallow microsculpture; eyes weakly convex and approximately half as long as postocular portion in dorsal view ( Fig. 26 ). Pronotum with weakly pronounced sexual dimorphism; punctation very fine and barely noticeable; microsculpture more pronounced than that of head. Elytra with moderately pronounced sexual dimorphism, approximately half as long as pronotum. Abdomen slightly broader than elytra; tergites III-IV and VII with sexual dimorphism; punctation fine to moderately fine, moderately dense on anterior tergites and very sparse on posterior tergites; interstices with distinct, but shallow microsculpture; posterior margin of tergite VII usually with, rarely without very narrow rudiment of a palisade fringe. (with fully developed secondary sexual characters): pronotum weakly oblong, approximately 1.05 times as long as broad, posterior margin strongly convex in the middle; elytra slightly less than half as long as pronotum, very shallowly impressed at most, with moderately granulose punctation, and with moderately pronounced sutural carinae extending along anterior 2/3 of suture ( Fig. 26 ); abdominal tergites II and III with median tubercles, both of them situated close to the anterior tergal impressions; process of tergite VII broadly triangular in lateral view ( Fig. 27 ), parallel, convex (cross-section), and apically rounded in antero-dorsal view ( Fig. 28 ); median lobe of aedeagus approximately 0.28 mm long, cristal process narrow and obliquely projecting away from ventral process in lateral view ( Figs 29-30 ). : pronotum weakly transverse; elytra unmodified and slightly more than half as long as pronotum; spermatheca as in Figs 31-32. E t y m o l o g y: The specific epithet is a latinized adjective derived from the name of the province where the type locality is situated. It refers to the fact that the species is the first representative of the subgenus to become known from Burdur . Figs 26-32 : Geostiba burdurica nov.sp. (26, 29: holotype): ( 26 ) male forebody; ( 27 ) male abdominal apex in lateral view; ( 28 ) posterior portion of male abdominal tergite VII in antero-dorsal view; ( 29-30 ) median lobe of aedeagus in lateral view; ( 31-32 ) spermatheca. Scale bars: 26: 0.5 mm; 27- 32: 0.1 mm. C o m p a r a t i v e n o t e s: Using the key in ASSING (2009) , G. burdurica would key out at couplets 91-93. For a supplement to this key, which accounts for the new species, see the following section on G. akiana .

The specimens were collected in a cypress forest with oak undergrowth at an altitude of approximately 1420 m , by sifting litter and grass roots near snow (SCHÜLKE, pers. comm).
