Belousova, E. N., 2007, Revision of the shield-bug genera Holcostethus Fieber and Peribalus Mulsant et Rey (Heteroptera, Pentatomidae) of the Palaearctic Region, Entomological Review 87 (6), pp. 701-739 : 724-725

Subgenus Tianocoris Belousova , subgen. n.

Type species Holcostethus manifestus (Kiritshenko, 1952) .

Diagnosis. The subgenus is most closely related to the preceding one, but the aedeagus bears three pairs of conjunctive membranous processes or, at least, two pairs of well-developed processes and a rudiment of the third pair; the pygofer forms pointed apical angles slightly attenuate inwards; the uneven area of the inner surface of the paramere is arcuately curved ( Figs. 61, 62 ); the spermatheca forms the spherical bulb and a sclerotized duct widened at the base ( Fig. 15 ); sternite IX is narrower, its proximal margin is more deeply emarginate and the apices are attenuate and obtused; laterotergite IX is widely rounded at the apex and slightly narrowed at the base.

Composition. The subgenus includes two species, P. manifestus (Kiritshenko) and P. tianshanicus sp. n., inhabiting the high mountains of the Pamiro-Alai and Tien Shan and reaching heights of nearly 3600 m.
