Geostiba renneri
sp.n.
det.
V
. Assing 2006 (cAss).
D e s c r i p t i o n: Species of relatively small size,
2.8 mm
(abdomen fully extended). Coloration: head dark brown; pronotum and elytra light brown; abdomen blackish, with the apex and the anterior segments indistinctly paler; legs testaceous; antennae brown, with the basal two antennomeres light brown.
Facies as in
Fig. 36
. Head with very shallow microreticulation (
Fig. 37
). Eyes moderately small (
Fig. 39
), weakly protruding from lateral outline of head, approximately half the length of postocular region in dorsal view. Antenna as in
Fig. 38
.
Pronotum apparently with weakly pronounced sexual dimorphism, approximately 1.15 times as wide as head (
Fig. 37
). Microreticulation slightly more distinct than that of head. Elytra with moderately pronounced sexual dimorphism, less than 0.6 times as long as pronotum.
Abdomen shiny; puncturation moderately dense and relatively coarse on tergites III-V, sparse and fine on posterior tergites; microsculpture composed of transverse striae and transverse meshes, more distinct on tergites
VI
and
VII
than on tergites III-V; posterior margin of tergite
VII
without palisade fringe; tergites III-VI without sexual dimorphism.

: pronotum approximately as long as wide, posterior margin distinctly convex (
Fig. 37
); elytra flat, with rather dense and coarse granulose puncturation, without sutural carina, but with distinct lateral carinae (
Figs 37, 39
); anterior abdominal tergites unmodified; process of tergite
VII
stout, massive, and short (
Figs 41-42
); sternite VIII with broadly convex posterior margin; median lobe of aedeagus as in
Fig. 43
; apical lobe of paramere shaped as in other species of the subgenus.
: unknown
E t y m o l o g y: The species is dedicated to Klaus Renner, Bielefeld, in appreciation of his life-long enthusiasm as a coleopterist and friend. Paul Wunderle discovered the
holotype
on 13 April, 2006, Klaus Renner´s 70
th
birthday, in a sample collected on the previous day.

D i s t r i b u t i o n a n d b i o n o m i c s:
Geostiba renneri
is probably endemic to the Oyuklu Da÷, north of Mu÷la (
Map 3
), and possibly also adjacent mountain ranges. The
holotype
was collected by sifting grass roots and pine litter in a limestone cirque at an altitude of slightly more than
1600 m
(
Fig. 44
).
