Podosilis zhongdiana Kazantsev , sp.n.

Figs 39–43 .

MATERIAL. Holotype, ♂, China, NW Yunnan, env. Zhongdi- an, 3100–3400 m, 4–5.VII.2002, A. Gorodinsky leg. ( ICM); paratypes, ♂ and ♀, same label ( ICM).

Description. Male. Dark brown to black; pronotum, except at lateral margins of layteral hairy ‘caps’, and prosternum testaceous ( Fig. 39 ).

Vertex flat, finely punctate, shining, with short hairs. Eyes small, interocular distance ca. 2.7 times greater than eye diameter. Clypeus small, transverse, rounded anteriorly. Palps slender, ultimate palpomeres elongate, considerably longer and wider than preceding palpomeres. Antennae filiform, attaining to elytral five sixths; antennomere 3 ca. 3 times longer than antennomere 2 and ca. 1.6 times longer than antennomere 4; antennomeres with short semi-erect pubescence ( Fig. 39 ).

Pronotum transverse, ca. 1.5 times wider than long, basally almost straight, without tooth before posterior angle; anteriorly slightly convex; medially with conspicuous broad impression; anterior angles rounded; sides with small hairy ‘cap’, not surpassing one third of side’s length, and semicircular opening at posterior angle; posterior angle moderately produced, with indistinctly cleft at apex. Scutellum subquadrate, rounded at apex ( Fig. 39 ).

Elytra ca. 2.5 times longer than wide at humeri, slightly widened posteriorly, with coarse dense punctuation, denser distally, and one longitudinal vein near suture. Pubescence short and sub-erect, not concealing the punctuation. Femoris and tibiae narrow, straight; ratio of hind leg tarsomeres — 1.3:1:0.8:0.6:1.

Spiculum gastrale very narrow, needle-shaped, parallel-sided. Aedeagus with sub-triangular, conspicuously incised medially ventral plate; dorsal plate broad, semicircular, denticulate; laterophyses approximate and parallel-sided, acute at apex, not denticulate ( Figs 41–43 ).

Female. Similar to male, but pronotum without complex armature, eyes smaller and antennae somewhat shorter ( Fig. 40 ).

Length: 5.8–6.0mm. Width (humerally): 1.6–1.8 mm.

DIAGNOSIS. Podosilis zhongdiana sp.n. somewhat resembles P. yunnana Wittmer, 1997 , distinguishable by the approximate and parallel-sided laterophyses, as well as by the sub-triangular ventral plate and semicircular dorsal plate of the aedeagus ( Figs 41–43 ).

ETYMOLOGY. The new species is named after the type locality.

Acknowledgements. It is my pleasant duty to express gratitude to Dr. C. Holzschuh (Villach, Austria), Dr. B. Korotjaev (St.-Petersburg), Dr. S. Murzin (Moscow) and Dr. Yu. Zaitsev (Moscow) for the possibility to study the soldier-beetles collected during their trips to China and Indochina.
