description: Sunius kizilcadagicus sp. n.
Figs 1-8
Type material: Holotype; MHNG; ♂, TURKEY, “TR. Antalya province, Kızılcadağ, 1550 m, 03.V.1975, leg. Besuchet & Löbl, #13 [under stones] / Holotypus ♂ Sunius kizilcadagicus sp. n. det. S. Anlaş 2016 ”. ‒ Paratypes, MHNG; 1♀; same data as holotype.
Type locality: Turkey, Antalia Province, Korkuteli district, Kızılcadağ, 1550 m.
Description: Small species (body length 3.0- 3.4 mm). Habitus as in Fig. 1. Coloration: body uniformly reddish yellow or forebody reddish and abdomen reddish brown; legs pale yellow, antennae reddish.
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 mediodorsal area slightly sparser; microsculpture absent; eyes small (Fig. 2), not distinctly projecting from lateral outline of head, approximately 1/3 the length of postocular region in dorsal view. Antennae moderately slender, approximately 0.80-0.82 mm long. Pronotum (Figs 1-2) approximately 1.10 times as long as wide and narrower than head; punctation dense and coarse, midline broadly impunctate; microsculpture absent. Elytra short and narrow (Figs 1-2), combined approximately as wide as pronotum, and at suture about 0.75-0.80 times as long as pronotum; punctation finer and denser than that of pronotum and weakly granulose; interstices without distinct microsculpture; hind wings strongly reduced. Abdomen about 1.10-1.15 times as wide as elytra, widest at segments VI-VII; punctation moderately dense and fine; interstices with shallow but distinct microsculpture; posterior margin of tergite VII without palisade fringe. Male abdominal sternite VII not markedly modified, but posterior margin very weakly concave in middle (Fig. 3); posterior margin of sternite VIII with relatively wide emargination, posteriorly with median cluster of weak pubescence (Fig. 4). Aedeagus (Figs 5-8) approximately 0.40 mm long, with apical portion of ventral process slightly indentate in lateral view and bulging in ventral view; internal sac with series of 5 stout medial sclerites and pair of slender subbasal sclerotized structures connected medioventrally.

Distribution: The new species is known so far only from Kızılcadağ, in western Korkuteli district of northeastern Antalya province, where it was collected under stones at an elevation of 1550 m.
Etymology: The name is derived from the type locality Kızılcadağ.
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 of the internal sac. Based on the similar morphology of the male primary and secondary sexual characters, S. kizilcadagicus sp. n. is closely related to S. brachati Assing, 2003 (Antalya province), S. aequus Assing, 2011 (Isparta province) and S. ulcerosus Assing, 2011 (Isparta province). The new species is readily separated from these species as follows:
- from S. brachati, by its smaller body size (S. brachati: forebody 2.3-3.0 mm), smaller eyes (S. brachati: at least ½ times as long as postgenae in dorsal view), larger head (S. brachati: head not wider than pronotum), by the lack of tubercule on abdominal sternite VIII (S. brachati: tubercule on abdominal sternite VIII small with few setae), by the internal sac bearing sclerotised spines, and by a different shape of the aedeagal ventral process (S. brachati: aedeagal ventral process broader in lateral view).
- from S. aequus by the different coloration (S. aequus: forebody reddish contrasting with dark-brown to blackish-brown abdomen), by the median cluster of sparse pubescence on the posterior portion of abdominal sternite VIII (S. aequus: abdominal sternite VIII posteriorly with median cluster of dense pubescence), by the different shape of the apical portion of aedeagal ventral process (S. aequus: apical portion of aedeagal ventral process almost straight in lateral view and rather slender in ventral view).
- from S. ulcerosus, by the different coloration (S. aequus: forebody reddish distinctly contrasting with abdomen dark-brown to blackish-brown), the lack of tubercule on the abdominal sternite VIII (S. ulcerosus: abdominal sternite VIII posteriorly with a median subcircular protuberance, the latter with a cluster of denser pubescence), and by the different shape of the apical portion of ventral process of the aedeagus (S. ulcerosus: apical portion of ventral process of aedeagus subapically broader in ventral view, and shorter and weakly curved in lateral view).
