Type material:

Holotype : TR [5] - Aydın, 15 km NNE Aydın, Imambaba T., 1410 m, 37°56'38N, 27°53'40E, 5.IV.2006, V. Assing GoogleMaps   / Holotypus  Sunius fortespinosus   sp. n. det. V. Assing 2006 (cAss)   . Paratypes: 4 , 2 : same data as holotype (cAss, cWun); 1   : same data, but leg. Wunderle (cWun); 1 , 1 : TR [18] - Izmir, WSW Hamamköy, Murtat Dağı, 1230 m, 38°00'52N, 27°56'56E, 9.IV.2006, V. Assing (cAss) GoogleMaps   .

Description:

Small species, 2.7-3.3 mm (abdomen extended). Habitus as in Fig. 25 View Figs 25-36 . Coloration: forebody uniformly yellowish red to reddish brown, with the elytra sometimes darker; abdomen dark brown to blackish, with the paratergites mostly paler brown; legs pale yellowish; antennae yellowish red.

Head very weakly oblong, less than 1.1 times as long as wide; lateral margins subparallel or indistinctly diverging posteriad in dorsal view; puncturation coarse, well-defined, and relatively sparse, in lateral area slightly denser than in median dorsal area; microsculpture absent ( Fig. 26 View Figs 25-36 ); eyes small ( Fig. 27 View Figs 25-36 ), weakly projecting from lateral outline of head, postocular region in dorsal view approximately 3 times as long as eyes or nearly so.

Pronotum approximately 0.90-0.95 times as wide as head and about 1.10 times as long as wide; microsculpture absent; puncturation very dense (except for the impunctate median line) and about as coarse as that of head ( Fig. 26 View Figs 25-36 ).

Elytra approximately as wide and at suture about 0.75 times as long as pronotum; puncturation ill-defined, much finer and shallower than that of pronotum; microsculpture shallow ( Fig. 26 View Figs 25-36 ). Hind wings reduced.

Abdomen about 1.15 times as wide as elytra, widest at segments VI-VII; puncturation relatively dense and fine; microsculpture shallow; posterior margin of tergite VII without palisade fringe.

: sternite VII not distinctly modified ( Fig. 28 View Figs 25-36 ); sternite VIII unmodified, except for posterior incision ( Fig. 29 View Figs 25-36 ); aedeagus shaped as in Figs 30-36 View Figs 25-36 , internal sac with series of five stout, long, and distinctly sclerotised spines ( Fig. 36 View Figs 25-36 ).

Etymology: The name (Lat., adj.) refers to the series of long and stout spines in the internal sac of the aedeagus.

Comparative notes:

In the keys in ASSING (2005b, 2005c), S. fortespinosus   would key out at couplets 3-3b together with S. longispinosus ASSING   , S. brevispinosus ASSING   , S. pauli ASSING   , and S. amanensis ASSING. From   all these species, S. fortespinosus   is readily separated by the completely different shape of the ventral process of the aedeagus and by the longer and darker spines in the internal sac. For illustrations of the male sexual characters of these species see the figures in ASSING (2005b, 2005c).

Distribution and bionomics:

The two localities are situated in the western parts of the Aydın Dağları ( Map 1 View Map 1 ), where the species is probably endemic. The specimens were found under stones and in gravel on a small patch of grassland at the edge of a pine forest ( Fig. 37 View Fig ) and on a rocky north slope with scattered oak trees and scanty vegetation at altitudes of 1230 and 1410 m.
