Etymology. The species is dedicated to Prof. Dr. Yusuf Kumlutaş, İzmir, who has carried out important zoological research in Turkey.

Description. Measurements (in mm) and ratios (range, n=11): AL 1.04–1.18; HL 0.60–0.64; HW 0.72–0.75; PW 0.68–0.74; PL 0.55–0.60; EL 0.45–0.48; EW 0.75–0.78; AW 0.79–0.85; TiL 0.50–0.52; TaL 0.30–0.32; ML 0.57–0.64 (n=7); TL 4.0–4.6; HL/HW 0.83–0.85; PW/HW 0.94–0.99; PW/PL 1.23–1.24; EL/PL 0.80–0.82; EW/ PW 1.05–1.10; AW/EW 1.05–1.09; TiL/TaL 1.63–1.67.

Habitus as in Fig. 17 . Coloration: forebody completely blackish, antennae rufous, legs reddish brown, with the femora slightly darker.

Head transverse, 1.20 times as wide as long (see Figs. 17–18 ); punctation coarse, dense, and areolate; pubescence short and reddish brown. Eyes relatively small, approximately 0.7-0.8 times as long as postocular region. Antennae slender; antennomere III approximately 2.4 times as long as wide; antennomeres V–X oblong ( Fig. 21 ).

Pronotum of distinctly transversely rectangular shape, approximately as wide as head (see Figs. 17–18 ); widest at anterior angles, but lateral margins almost parallel; anterior and posterior angles marked, anterior and posterior angles each with a long seta of little more than half length of lateral margin of pronotum; posterior margin distinctly convex; dorsal surface with slightly pronounced impressions, punctation similar to that of head, but slightly sparser and coarser; pubescence of similar length as that of head, but less fine.

Elytra transversely rectangular, short (see Figs. 17–18 ); microsculpture absent; punctation very dense and distinctly granulose, interstices on average approximately as wide as diameter of punctures; pubescence reddish brown, more distinct than that of head and pronotum. Hind wings totally reduced.

Abdomen wider than elytra (see Fig. 17 ), widest at segment V, segments III–VI transverse, tergites III–V approximately 2.2 as wide as long; punctation very dense and very fine; interstices with distinct fine microsculpture; pubescence dark brown; posterior margin of tergite VII with palisade fringe.

Male: sternite VII in posterior median area slightly depressed and with some modified dark stout setae, posterior margin weakly concave ( Fig. 20 ); sternite VIII with deeply and acutely incised posterior margin, pubescence unmodified ( Fig. 19 ); ventral process of aedeagus in ventral view subapically slightly widened and apically pointed, in lateral view weakly bent ( Figs. 22–24 ).

Comparative notes. The species is distinguished from all its consubgeners by the morphology of the aedeagus and also completely different coloration (see above). In addition, A. kumlutasi is readily separated from A. orgeli and A. gusarovi especially by the much longer antennae and by the wider incision of the posterior margin of the male sternite VIII.

Distribution and bionomics. The new species was collected in three localities in the Akdağlar and Murat Mountains, in the provinces of Kütahya and Uşak, central-western Anatolia, in grassland at altitudes of 1730–2080 m. They were found in the nests of Tetramorium sp.
