Geostiba (Tropogastrosipalia) renneri   sp.n. ( Figs 36-44 View Figs 36-43 View Fig , Map 3 View Map 3 )

Holotype: TR [25] - Mu ÷la, 12 km NNE Mu ÷la, 1620 m, grass roots, pine litter, 37°19'02N, 28°22'26E, 12.IV.2006, P. Wunderle GoogleMaps   / Holotypus 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 View Figs 36-43 . Head with very shallow microreticulation ( Fig. 37 View Figs 36-43 ). Eyes moderately small ( Fig. 39 View Figs 36-43 ), weakly protruding from lateral outline of head, approximately half the length of postocular region in dorsal view. Antenna as in Fig. 38 View Figs 36-43 .

Pronotum apparently with weakly pronounced sexual dimorphism, approximately 1.15 times as wide as head ( Fig. 37 View Figs 36-43 ). 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 View Figs 36-43 ); elytra flat, with rather dense and coarse granulose puncturation, without sutural carina, but with distinct lateral carinae ( Figs 37, 39 View Figs 36-43 ); anterior abdominal tergites unmodified; process of tergite VII stout, massive, and short ( Figs 41-42 View Figs 36-43 ); sternite VIII with broadly convex posterior margin; median lobe of aedeagus as in Fig. 43 View Figs 36-43 ; 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.

C o m p a r a t i v e n o t e s: Using the key in ASSING (2005a), G. renneri   , as well

as G. nifica   and G. atromontis   would key out at couplet 77:

77: elytra with fold-like elevation or tubercle near posterior angles, or with bulging lateral margins...........................................................................................................77a

-: elytra without fold-like elevation or tubercle, lateral margins not bulging............80

77a Pronotum without or with weakly pronounced sexual dimorphism (up to 1.15 times as long as wide, posterior margin broadly convex) in large males, posterior margin more or less distinctly convex ( Figs 2 View Figs 1-12 , 30 View Figs 30-34 , 37 View Figs 36-43 ). Western Anatolia............................77b

1192

- Pronotum with more pronounced sexual dimorphism, either distinctly elongated posteriorly (and covering scutellum) or posterior margin pointed in the middle. Southern Anatolia (Antalya, Mersin)..........................................................................78

77b: process of tergite VII short, stout, and apically obtuse ( Figs 41-42 View Figs 36-43 ); aedeagus with larger cristal process ( Fig. 43 View Figs 36-43 ). Mu÷la: Oyuklu Da÷ ( Map 3 View Map 3 )........ G. renneri   sp.n.

-: process of tergite VII long, slender, and apically acute ( Figs 5 View Figs 1-12 , 32 View Figs 30-34 ). median lobe of aedeagus with smaller and more slender cristal process ( Figs 8-9 View Figs 1-12 , 33 View Figs 30-34 ). Distribution different ................................................................................................77c

77c Pronotum without appreciable sexual dimorphism ( Fig. 2 View Figs 1-12 ).: carina in posterior angles of elytra narrow and not covered with coarse granula ( Figs 2, 4 View Figs 1-12 ); process of tergite VII more erect ( Fig. 5 View Figs 1-12 ). Izmir: Nif Da÷ı ( Map 3 View Map 3 ) ......................... G. nifica   sp.n.

-: pronotum in large weakly oblong ( Fig. 30 View Figs 30-34 ); carina in posterior angles of elytra broader, of more irregular shape, and usually with more or less coarse granula ( Figs 30-31 View Figs 30-34 ); process of tergite VII less erect ( Fig. 32 View Figs 30-34 ). Manisa: Karada÷ (Spil Dag) ( Map 3 View Map 3 )........................................................................... G. atromontis   sp.n.

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 View 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 View Fig ).
