Gunarus korkutelensis Nabozhenko & Keskin , sp. n.

( Fig. 1b , d, g, i. Fig. 2 c)

Male. Body strongly shining, black, legs and antennae red-brown. Head widest at eyes level. Eyes widely placed, strongly convex. Ratio of head width at eyes to distance between eyes – 1.5. Outer margin of genae not angulate. Outer margin of head at junction of gena and clypeus straight, without emargination. Genae not raised, relative to other surface of head (lateral view). Head with shallow transverse depression between frons and clypeus. Punctation of head not coarse, moderately dense (diameter of punctures subequal to distance between them); punctures rounded, only near eyes longitudinally elongated, but not merged into long distinct rugae. Antennae long, their four apical segments extending beyond base of pronotum. Ratio of length/width of 2–11 antennal segments: 0.5/0.5; 1.6/0.6; 1.1/0.6; 1.1/0.6; 1.2/0.6; 1.2/0.6; 1.5/0.6; 1.5/0.6; 1.4/0.7; 1.8/0.7. 11th antennal segment elongated (2.57 times as long as wide), weakly arcuated, banana-shaped, 1.3 times as long as 10th.

Pronotum cordiform, transverse (1.2 times as wide as long), 1.3 times as wide as head, widest before the middle. Lateral sides of pronotum distinctly rounded, emarginate near base. Punctation of pronotum moderately coarse and moderately dense, punctures rounded, only on sides of disc weakly elongate.

Elytra elongate, oval (1.6 times as long as wide), 1.6 times as wide as head, 1.2 times as wide and 2.4 times as long as pronotum. Intervals weakly convex, 5th interval without granules.

Abdominal sternites covered with recumbent light setae. 5th abdominal ventrite margined at the apex. Tibiae straight, strongly recumbent. 2–3 tarsomeres of fore tarsi widened, 1.3 times as wide as long.

Parameres spear-shaped, elongated. Sclerites of penis arcuate apically.

Length of body 6,5 mm.

Female. Body robust, antennae shorter, only their three apical segments extending beyond base of pronotum. Pronotum more tranverse.

Type material. Holotype (male) [Zoological Institute, St.-Petersburg, Russia]: Turkey, prov. Antalya, 10 km S Korkuteli, N36o58’ 707’’, E30o09’ 691’’, 1111 m, 10.05.2009 (leg. M.V. & S.V. Nabozhenko, B. Keskin); 18 paratypes (11 males and 7 females) with same labels, 4 males and 3 females in ZIN, 7 males and 4 females in Ege University. 1 paratype, male: “ TR: Prov.: Antalya, Umg. Korkuteli, ca. 1000 m, 4. Mai 1992 leg. U. Heinig” and “ Gunarus sp.? det. Schawaller 1999” [ SMNS].

Etymology. Named after the type locality of Korkuteli.

Bionomics. This species inhabits xerophilous forests of Quercus coccifera which is widespread on the plains and hills near Korkuteli.

Diagnosis. This species is closely related to G. g a y i r b e g i sp. n. Differences are given in the key.

Notes. The new species is distributed in the same range (Akdag mountain) as G. gayirbegi sp. n., however both species are isolated from each other by extensive mountain deserts without woody vegetation (between northern and southern Akdag).
