( Figs. 7–12 ; Map 1)

Type material. Holotype: TURKEY: ♂ “ TR – Denizli province, Tavas, Gölgeli Mountains, Bozdağ ski resort road, 2033 m, 37°19'57"N, 29°10'47"E, 03.V.2014, leg. Yağmur & Örgel. / Holotypus ♂ Sunius golgeliensis sp. n. det. S. Anlaş 2014” ( AZMM). Paratypes: TURKEY: 1♀, same data as holotype ( AZMM); 1♂, 3♀, Denizli province, Tavas, Gölgeli Mountains, 1900 m, 37°14'16"N, 29°04'07"E, 26.IV.2014, leg. Yağmur & Örgel ( AZMM).

Description. Small species, body length 2.6–3.0 mm. Habitus as in Fig. 7 . Coloration: forebody uniformly reddish brown, with the head and posterior area of elytra slightly darker; abdomen dark brown, with the paratergites mostly paler brown; legs pale yellow; antennae yellowish red.

Head oblong ( Figs. 7–8 ), approximately 1.10–1.15 times as long as wide; lateral margins subparallel, indistinctly diverging posteriad in dorsal view; punctation coarse, well-defined, and relatively sparse, in lateral area slightly denser than in medio-dorsal area; microsculpture absent, eyes small ( Fig. 8 ), weakly projecting from lateral outline of head, postocular region in dorsal view approximately 2.5–3.0 times as long as eyes. Antennae moderately slender, approximately 0.75–0.80 mm long.

Pronotum ( Fig. 7–8 ) approximately 0.90 times as wide as head and about 1.05–1.10 times as long as wide; microsculpture absent; punctation as coarse as that of head, median line impunctate.

Elytra ( Fig. 7–8 ) approximately as wide as and at suture about 0.75 times as long as pronotum; punctation illdefined, much finer and shallower than that of pronotum; microsculpture indistinct. Hind wings totally reduced.

Abdomen ( Fig. 7 ) about 1.15–1.20 times as wide as elytra, widest at segments VI–VII; punctation relatively dense and fine; microsculpture shallow; posterior margin of tergite VII without palisade fringe.

Male: sternite VII not distinctly modified ( Fig. 9 ); posterior margin of sternite VIII with relatively wide emargination, without additional modifications ( Fig. 10 ), aedeagus approximately 0.40 mm long, shaped as in Figs. 11– 12 , in lateral view with basally almost straight ventral process ending in a very curved apex, internal sac with a series of 6 stout spines.

Comparative notes. The species is distinguished from all its congeners by the different shape of the ventral process of the aedeagus. The similarity in the male sexual characters suggests that S. golgeliensis sp. n. is most closely related to S. yagmuri sp. n. From S. yagmuri sp. n. this species is readily separated by the shorter apical portion of ventral process less curved in lateral view, by the series of 6 spines in the internal sac (instead of 5 in S. yagmuri ).

Etymology. The name is derived from the Gölgeli Mountains, the mountain range where the type locality is situated.

Distribution and bionomics. The new species was collected in two localities in the Gölgeli Mountains, Denizli province, at altitudes of 1900 and 2030 m (Map 1).
