Geostiba (Sipalotricha) orduica View in CoL sp.n. ( Figs 98-107 View Figs 98-107 , Map 8 View Map 8 )

Holotype 3: TR [22] - Ordu, 15 km S Ordu, S Kabaduz, 990 m, mixed forest, 40°48'59N, 37°54'28E, 30.VII.2006, V. Assing GoogleMaps / Holotypus 3 Geostiba orduica sp.n. det. V. Assing 2006 (cAss). Paratypes: 13, 4♀♀: same data as holotype (cAss) GoogleMaps ; 6 exs.: same data, but leg. Schülke (cSch, OÖLL) GoogleMaps .

D e s c r i p t i o n: Small species, 2.0- 2.3 mm (abdomen extended). Coloration: body reddish brown to brown, with abdominal segment VI and adjacent segments more or less extensively infuscate and sometimes also the head slightly darker; legs yellowish; antennae yellowish brown.

Facies as in Fig. 98 View Figs 98-107 . Head with very shallow microreticulation and some shine ( Fig. 99 View Figs 98-107 ); puncturation very fine and very sparse, barely noticeable. Eyes moderately small ( Fig. 100 View Figs 98-107 ), not distinctly projecting from lateral outline of head, approximately 0.35-0.4 times the length of postocular region in dorsal view.

Pronotum weakly transverse, approximately 1.1 times as wide as long and 1.15 times as wide as head ( Fig. 99 View Figs 98-107 ); microsculpture similar to that of head or slightly more pronounced; puncturation similar to that of head.

Elytra 0.50-0.55 times as long as pronotum ( Fig. 99 View Figs 98-107 ), without sexual dimorphism; microsculpture similar to that of head and pronotum; puncturation very fine, but slightly more distinct than that of head and pronotum.

Abdomen approximately 1.15 times as wide as elytra ( Fig. 98 View Figs 98-107 ), with distinct microsculpture, and with sparse fine puncturation; posterior margin of tergite VII with or without narrow rudiment of a palisade fringe.

3: posterior margin of tergite VIII in the middle weakly concave ( Fig. 101 View Figs 98-107 ); posterior margin of sternite VIII obtusely angled in the middle ( Fig. 102 View Figs 98-107 ); median lobe of aedeagus with strongly reduced crista apicalis ( Fig. 103 View Figs 98-107 ); apical lobe of paramere as in Fig. 104 View Figs 98-107 .

♀: posterior margin of tergite VIII in the middle very weakly concave ( Fig. 105 View Figs 98-107 ); posterior margin of sternite VIII weakly convex and with row of numerous modified marginal seta, in the middle not distinctly concave ( Fig. 106 View Figs 98-107 ); spermatheca as in Fig. 107. View Figs 98-107

E t y m o l o g y: The name (adj.) is derived from Ordu, the province where the type locality is situated.

C o m p a r a t i v e n o t e s: The geographically closest consubgeners are G. euxina PACE and G. macronorum PACE from the surroundings of Maçka in Trabzon. From both species, G. orduica is distinguished especially by the concave posterior margin of the male and female tergite VIII, the posteriorly obtusely angled male sternite VIII, the reduced crista apicalis of the median lobe of the aedeagus, the shape and

chaetotaxy of the paramere, as well as by the shape of the spermatheca. From G. euxina , it is additionally separated by slightly larger eyes. For a supplement to the key in ASSING (2005a) see the following section on G. soganlica .

D i s t r i b u t i o n a n d b i o n o m i c s: The type locality is situated in the mountains to the south of Ordu in Ordu province, northeastern Anatolia ( Map 8 View Map 8 ). The specimens were collected by sifting the leaf litter and soil in a mixed forest with alder, spruce, bramble, and ivy at an altitude of almost 1000 m.
