Geostiba (Tropogastrosipalia) atromontis   sp.n. ( Figs 30-35 View Figs 30-34 View Fig , Map 3 View Map 3 )

Holotype: TR [30] - Manisa, 10 km S Manisa, Karada ÷, 1200 m, roadside, 38°33'26N, 27°23'13E, 15.IV.2006, V. Assing GoogleMaps   / Holotypus Geostiba atromontis   sp.n. det. V. Assing 2006 (cAss). Paratypes: 3: same data as holotype (cAss) GoogleMaps   ; 2: same data, but leg. P. Wunderle (cWun) GoogleMaps   ; 3: N38°32'31, E027°27'44, (21), Türkei, Manisa, Sipil Dagi, Milli Parki , 1080 m, 25.4.2006, l.

D e s c r i p t i o n: This species is extremely similar to G. nifica   , so that a detailed description would be redundant. Instead, only the primary and secondary sexual characters are described:

(large): pronotum weakly oblong, up to 1.1 times as long as wide ( Fig. 30 View Figs 30-34 ); elytra with similar modifications as in G. nifica   , but the carinae in posterior angles broader, of more irregular shape, and covered with more or less coarse granules ( Figs 30-31 View Figs 30-34 ); process of

tergite VII of similar shape as in G. nifica   , but slightly less erect ( Fig. 32 View Figs 30-34 ); aedeagus similar to that of G. nifica   ( Fig. 33 View Figs 30-34 ).

: spermatheca as in Fig. 34. E t y m o l o g y View Figs 30-34 : The name (Lat.: of the black mountain) refers to the Turkish name of the mountain range, where the species was discovered.

I n t r a s p e c i f i c v a r i a t i o n: The male secondary sexual characters are subject to considerable intraspecific variation; they are fully developed only in four of the seven male type specimens.

C o m p a r a t i v e n o t e s: As indicated above, G. atromontis   is extremely similar to G. nifica   ; both species can be distinguished only based on the modifications of the elytra and tergite VII of large males with pronounced secondary sexual characters. Although these differences are slight, they are interpreted as evidence of interspecific rather than intraspecific variation, not only because they seem to be constant, but also because the ranges of both populations are separated by a considerable stretch of low-altitude plain. Using the key in ASSING (2005a), both G. nifica   and G. atromontis   would key out at couplet 77 (see supplementary key in section on G. renneri   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: Thespeciesisprobablyendemictothe Karada÷ range (Spil [=Sipil] nature reserve) to the south of Manisa ( Map 3 View Map 3 ). The types were found under stones on limestone grassland ( Fig. 35 View Fig ) and sifted from litter below bushes and near rocks at altitudes of 1080-1250 m.
