Habitus as in Fig. 95 . Head, maxillary palpomeres, antennomeres 4–11 and abdomen reddish-brown; pronotum brown; lateral and basal portions of pronotum, elytra and apical part of abdomen yellow-brown; mouthparts, antennomeres 1–3 and legs yellow. Head with distinct, transverse and very dense microsculpture, finer in middle, diagonal between anteocellar foveae and infraorbital ridges; neck with dense and transverse meshes; pronotum with fine transverse microreticulation, finer in mediobasal third; apical part of scutellum without sculpture; abdomen with dense and transverse microsculpture. Head with moderately fine, dense punctation, finer and sparser in middle between anteocellar foveae, coarser on infraorbital ridges; neck with sparse and fine punctation; pronotum with very dense punctation, slightly coarser and deeper than that on head, finer and sparser in mediobasal third; punctation of elytra as that on pronotum, finer and sparser in parascutellar portion and middle, coarser and deeper in apical portion, on each elytron forming very tangled and vague six longitudinal rows of punctures; abdominal tergites with indistinct, very fine and sparse punctation. Head 1.5 times as broad as long, with moderately wide anteocellar foveae, reaching level of apical margin of eye; postocular ridges somewhat smooth. Antennomere 2 slightly narrower than basal antennomere, 3 slightly longer than 2, 4 shorter and broader than 3, 5–7 slightly broader than 4, 8–9 slightly shorter and broader than 7, 10 shorter than 9, apical antennomere 1.4 times as long as preapical antennomere, from middle gradually narrowed toward rounded apex. Pronotum convex, 1.8 times as broad as long, 1.7 times as broad as head, widest in middle, slightly more narrowed posteriad than anteriad; apical margin widely rounded and distinctly protruded anteriad; lateral portions deeply impressed, with moderately wide and deep oval spot in front of middle. Elytra slightly broader than long, more than twice as long as pronotum, reaching basal margin of abdominal tergite IV, with straight apical margins. Metatarsus 1.6 times as long as metatibia. Male. Aedeagus with wide basal bulb, gradually narrowed toward widely rounded apex; parameres exceeding apex of median lobe, widened apically, with two short apical and one preapical setae; internal sac very long, spirally folded in basal portion ( Fig. 99 ). Lateral aspect of aedeagus as in Fig. 100 . Female unknown. Comparative notes. Regarding the shape of the relatively narrow aedeagus with widely truncate apex and long parameres, this species is similar to the Chinese A . cornatipenis sp. n. , from which it is distinguished by a paler and larger body, longer antennomeres 6–10, distinctly protruding anterior angles of the pronotum, and wider apical portions of the parameres. Distribution. The species is known only from the type locality in Gissar mountain range, Tajikistan ( Fig. 81 ). Natural history. The specimen was collected at an elevation of 2500 m a.s.l. Detailed ecological data are unknown. Etymology. Patronymic, the species is named in memory of the famous Russian staphylinidologist Anna L`vovna Tichomirova (1940–1987).
