Description. Habitus as in Fig. 17 View FIGURES 17–24 . Body 3.9–4.5 mm long. Coloration: head and pronotum dark brown, posterior half of elytra yellowish, with anterior area blackish, abdomen dark brown or blackish, antennae reddish brown and legs with the femora dark-brown, the tibiae brown, and the tarsi yellowish brown.
Head transverse, 1.15-1.25 times as wide as long ( Figs 17-18 View FIGURES 17–24 ); dorsal surface convex, punctation shallow, very dense, and umbilicate; pubescence short, decumbent and yellowish but not dense. Eyes relatively small in size with very slightly protruding, in dorsal view distinctly shorter than postocular region. Antennae moderately slender, 1.05- 1.15 mm long, all antennomeres oblong, antennomere III approximately 2.2-2.3 times as long as wide ( Fig. 17 View FIGURES 17–24 ).
Pronotum octagonal shape, approximately 1.10-1.15 times as wide as long ( Figs 17-18 View FIGURES 17–24 ); slightly narrower than head, approximately 0.95 times as broad as head; posterior margin slightly convex; laterally with a shallow impression on either side; punctation somewhat coarser, non-umbilicate and sparser than that of head; pubescence of similar as that of head, slightly more distinct.Anterior and posterior margin of pronotum with 4-6 black setae; lateral margins each with two long black setae (on avarege 2.1-2.4 mm); one in anterior angle and one in posterior angle.
Elytra distinctly transverse, 1.80-1.85 times as long, 1.10-1.15 times as wide as pronotum ( Figs 17-18 View FIGURES 17–24 ); approximately 0.65-0.70 times as long as pronotum; microsculpture absent; punctation distinctly granulose; surface somewhat more shiny than that of head and pronotum; pubescence of similar as that of pronotum; posterior margin of each elytron with 5-7 long black setae. Hind wings completely reduced.
Abdomen approximately 0.9 times as broad as elytra; widest at segment V, segments III–VI distinctly transverse ( Fig. 17 View FIGURES 17–24 ), punctation very dense and very fine on anterior tergites, gradually decreasing in density from tergite III to tergite VIII, moderately dense on tergites VII and VIII; interstices with distinct fine microsculpture; pubescence yellowish and decumbent; posterior margin of tergite VII with palisade fringe.
♂: sternite VII in posterior median area slightly depressed and with modified dark and short setae, posterior margin distinctly concave ( Fig. 19 View FIGURES 17–24 ); posterior incision of sternite VIII in the middle very narrow and acute, pubescence unmodified ( Fig. 20 View FIGURES 17–24 ); aedeagus approximately 0.62-0.68 mm long and as in Figures 21-24 View FIGURES 17–24 , apical portion of ventral process with slender-shaped in lateral view.
Comparative notes. Astenus kirani is distinguished from all its consubgeners by the different morphology of the aedeagus, especially in lateral view. Based on the similar morphology of the male primary and secondary sexual characters, the new species is closely related to Astenus sivasicus Anlaş, 2019 (Sivas province), but distinguished from A. sivasicus from by the smaller body ( A. sivasicus : 4.5-4.9 mm), by the much more transverse elytra (A. siv- asicus sp. n.: elytra 1.70-1.75 times as wide as long), by the narrower posterior incision in sternite VIII, and by the different shape of the aedeagus both ventral and lateral view, especially apically more slender in lateral view.
For descriptions and illustrations of A. sivasicus see Anlaş (2019), and also see key to the Turkish Eurysunius species.
Etymology. The species is dedicated to Dr. Kadri Kıran, Edirne ( Turkey), a specialist on Formicidae , who has carried out important entomological studies in Turkey.
Distribution and bionomics. The species was collected two localities from Koyulhisar and Suşehri districts in Sivas province ( Map 1 View MAP 1 ), in various grassland areas at altitudes of 1860-2030 m. The specimens were found in the nests of Tetramorium immigrans Santschi, 1927 .
