Treatment

Peribalus (Tianocoris) tianshanicus Belousova, sp. n.

Diagnosis. This is the only species, in which the aedeagus has three pairs of well-developed conjunctive processes. It also differs from the closely related P. (T.) manifestus in the narrow sclerotized median plates not adjoining each other.

Description. Dorsal side of body golden-sandy to ochraceous, with very dense fine punctation (concolorous or dark) making surface not smooth. Lower side yellow, with very sparse punctation. Abdominal segments with agglomeration of sparse black punctures in anterior and posterior corners of tergites. Antenna yellowish brown with darker apical segments. Length of body 8–10.2 (8.79) mm, b. lw 1.51–1.69 (1.62).

Head narrowed anteriorly, emarginate before eyes [h. wl 1.10–1.23 (1.17)], medium-sized, l. bh 4.10– 4.64 (4.33). Jugae longer than clypeus, converging at apex, occasionally not covering apex of clypeus ( Fig. 84 View Figs ). Eye small, ds 1.37–1.45 (1.41). Antenna long, l. ba 1.73–2.21 (2.02).

Pronotum transverse [p. wl 2.07–2.42 (2.18)], with straight sides bordered with yellow costa deflexed upwards, with lateral depressions and rounded lateral angles. Scutellum slightly emarginate at sides, s. lw 0.94–1.07 (0.98).

Male genitalia. Pygofer as in Fig. 82 View Figs . Aedeagus with 3 pairs of conjunctive processes ( Figs. 28 View Figs , 34 View Figs ). Sclerotized median plates slightly widened toward apex, not contacting. Theca with lateral processes. Parameres in form of overturn “L,” with slightly pro-jecting sensory lobe and arcuately curved uneven area of inner surface ( Fig. 62 View Figs ).

Female genitalia. Spermatheca with small spherical bulb bearing 2 processes and with sclerotized duct spherically widened at base (as in Fig. 15 View Figs ). Sternite IX short, wide, with attenuate apices. Laterotergite IX slightly narrowed toward base ( Fig. 104 View Figs ).

Distribution. The Western and Central Tien Shan: the Kirghiz, Talas Ala Tau, Pskem, Chatkal, Ferghana, Dzhumgol, and Zailiiskii Ala Tau Mt. Ranges.
