Sunius yagmuri sp. n.

( Figs. 1–6 ; Map 1)

Type material. Holotype: TURKEY: ♂ “ TR. – Denizli province, Acıpayam, Akkaya Hill, 1707 m, 37°25'08"N, 29°35'49"E, 27.IV.2014, leg. Yağmur & Örgel. / Holotypus ♂ Sunius yagmuri sp. n. det. S. Anlaş 2014” ( AZMM). Paratypes: TURKEY: 3♂, 11♀, same data as holotype ( AZMM).

Description. Small species, body length 2.5–3.1 mm. Habitus as in Fig. 1 . Coloration: forebody uniformly reddish brown; abdomen dark brown to blackish, legs pale yellow, antennae yellowish red.

Head oblong ( Figs. 1–2 ), approximately 1.15 times as long as wide; lateral margins subparallel in dorsal view; punctation coarse, well-defined and dense, in medio-dorsal area slightly sparser; microsculpture absent, eyes small ( Fig. 2 ), weakly projecting from lateral outline of head, postocular region in dorsal view approximately 3 times as long as eyes. Antennae moderately slender, approximately 0.80–0.85 mm long.

Pronotum ( Figs. 1–2 ) approximately 1.10 times as long as wide and approximately as wide as head; punctation as coarse as that of head, median line impunctate; microsculpture absent.

Elytra ( Figs. 1–2 ) approximately as wide as and at suture about 0.75–0.80 times as long as pronotum; punctation finer and denser than that of pronotum and weakly granulose; hind wings totally reduced.

Abdomen ( Fig. 1 ) about 1.10–1.15 times as wide as elytra, widest at segments VI–VII; punctation moderately dense and fine; microsculpture shallow; posterior margin of tergite VII without palisade fringe.

Male: sternite VII not distinctly modified ( Fig. 3 ); posterior margin of sternite VIII with relatively wide emargination, without additional modifications ( Fig. 4 ), aedeagus approximately 0.40–0.45 mm long and distinctive, in lateral view with basally straight and apically curved ventral process, internal sac with series of 5 stout spines, in ventral view with pair of slender apical internal structures ( Figs. 5–6 ).

Comparative notes. The species is distinguished from all its congeners by the different shape of the ventral process of the aedeagus and by the shape of the spines in the internal sac. For illustrations of the male sexual characters of the other species see the figures in Assing (2001, 2003, 2005a, b, c, 2006, 2011b). Based on the similar morphology of the male primary and secondary sexual characters, S. yagmuri sp. n. is closely related to S. golgeliensis sp. n. (see below).

Etymology. The species is dedicated to Dr. Ersen Aydın Yağmur, Manisa, a specialist on Arachnids, who collected some of the type specimens of this new species.

Distribution and bionomics. The new species was collected in only one locality at the Akkaya Hill, Denizli province (Map 1). The type specimens were found under stones and sifted from grass roots at an altitude of about 1700 m.
