D e s c r i p t i o n: Body length 2.5-3.2 mm. Coloration: head blackish-brown to black; pronotum brown to dark-brown; elytra yellowish-brown to reddish-brown; abdomen blackish-brown to blackish, with the anterior segments occasionally slightly paler; legs yellowish; antennae yellowish-brown, with the basal antennomere(s) yellowish.
Head approximately as wide as long; punctation extremely fine, barely noticeable; surface with shallow microreticulation. Eyes moderately convex, approximately half as long as postocular region in dorsal view ( Fig. 9 View Figs 9-12 ).
Pronotum with moderate sexual dimorphism; punctation extremely fine, barely noticeable; microreticulation usually slightly more pronounced than that of head.
Elytra with moderately pronounced sexual dimorphism, approximately half as long as pronotum ( Fig. 9 View Figs 9-12 ); microsculpture indistinct, interstices glossy. Hind wings absent.
Abdomen slightly broader than elytra; punctation very fine and sparse; microreticulation distinct; posterior margin of tergite VII without palisade fringe; tergites III-IV without sexual dimorphism; posterior margin of tergite VIII convex in both sexes.
(with fully developed secondary sexual characters): pronotum approximately 1.15 times as long as broad, moderately elongated posteriad, posterior margin strongly convex in the middle; elytra more or less extensively and rather shallowly impressed, with granulose punctation, and moderately pronounced, very narrow sutural carinae extending along anterior 3/5-2/3 of suture ( Fig. 9 View Figs 9-12 ); anterior tergites unmodified; process of tergite VII short and apically acute, in lateral view suberect and stout ( Fig. 10 View Figs 9-12 ), in antero-dorsal view narrow; median lobe of aedeagus approximately 0.28 mm long, with very fine cristal process ( Fig. 11 View Figs 9-12 ).
: pronotum approximately as wide as long, posterior margin broadly and weakly convex; elytra without impression and with fine, non-granulose punctation; proximal portion of spermatheca twisted ( Fig. 12 View Figs 9-12 ).
I n t r a s p e c i f i c v a r i a t i o n: As in other species of the subgenus Tropogastrosipalia , the male secondary sexual characters may be nearly or completely absent in small males.
E t y m o l o g y: The specific epithet is the present participle of the Latin verb fodere (to pierce) and alludes to the spine-like shape of the cristal process of the aedeagus.
C o m p a r a t i v e n o t e s: UsingthekeyinASSING (2009), the species would key out at couplet 107. For a supplement to this key see the comparative notes in the section on G. pungens .
D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: Geostiba fodens was discovered in the Davraz Tepe, a mountain range to the southwest of Eğirdir, where the species is probably endemic. The specimens were collected from under stones on a sparsely vegetated slope ( Fig. 13 View Fig ) at an altitude of nearly 1700 m, and by breaking porose calcareous stones below a snowfield at an altitude of 1780 m.
