Description: Habitus as in Fig. 75. Body 4.4–5.6 mm long. Coloration: head and pronotum brown, elytra dark brown, with the posterior 1/3 of elytra yellowish, anteriorly usually each with one light yellow spot, abdominal segments I–IV dark brown, following segments blackish; antennae and legs reddish brown.

Head distinctly oblong (Figs. 75–76), approximately 1.2 times as long as wide; punctation umbilicate and dense, pubescence short, reddish yellow and relatively sparse; eyes convex, large and prominent. Antennae long (approximately 1.2 mm) and slender, third antennomere about three times as long as wide; all antennomeres oblong (Fig. 75).

Pronotum oval and convex; longer than wide, approximately 0.85–0.90 times as long as wide and approximately 0.90 times as wide as head and distinctly narrowed anteriorly and posteriorly (Figs. 75–76); each lateral side of prontum with two long setae, punctation similar to that of head, but moderately denser and larger, interstices without microsculpture; pubescence yellowish and denser than head.

Elytra oblong, slighty broader than pronotum, approximately 1.10–1.15 times as wide as pronotum (Figs. 75–76); punctation dense and granulose, but coarser than that of head and pronotum; pubescence yellowish, little more distinct than that of head and pronotum. Hind wings present.

Abdomen narrower than elytra, approximately 0.85–0.90 times as wide as elytra (Fig. 75); punctation fine and dense, surface with microsculpture composed of transverse meshes; pubescence of abdominal segments I–IV yellowish, and blackish on the following segments.

Male: Sternite VII in mediobasal area weakly concave and slightly depressed, with some modified dark stout setae (Fig. 77); posterior incision in the middle very narrow and acute in sternite VIII, without modified pubescence (Fig. 78). Aedeagus 0.75–0.80 mm long. Ventral process of aedeagus apically expanded in lateral view (Figs. 79–80). Median lobe of aedeagus slightly narrowed to apical region in ventral view (Fig. 81).

Etymology: The name of the new species is dedicated to the memory of French entomologist, Henri Coiffait (1907–1989).

Differential Diagnosis: It seems that A. henrii is a member of A. procerus group within the nominate subgenus. But, the subgeneric status of the new species should be confirmed by molecular studies. This new species can be distinguished from other congeners of A. procerus group in Turkey and adjacent regions by the different morphology of the male sexual characters. A. henrii separated from its congeners by the presence of slightly narrowed apex of the ventral process of the aedeagus in ventral view, and by expanding and rectangular shape in the apical area in lateral view.

Distribution and Bionomics: A. henrii was collected in several localities in Kayseri and Adana provinces in Turkey (Fig. 82). The specimens of the new species were collected under stones in grassland, at altitudes of 1670–2180 m.
