Podosilis cinderella Kazantsev , sp.n.

Figs 1–11 .

MATERIAL. Holotype, ♂, China, Yunnan, Xiaguan (S Dali), 1370 m, 29.VII.2002, S. Murzin leg. ( ICM); paratypes, 2 ♂♂ and

♀, same label; ♂, Yunnan, Cangshan Mts , E slopes, 25.43°N 100.06°E, 2500–3000 m, V.Kubáň leg. ( ICM) .

Description. Male. Dark brown to black; labial palpomeres 1–3, pronotum and prosternum testaceous ( Fig. 1 ).

Vertex flat, finely punctate, shining, with short hairs. Eyes small, interocular distance ca. 3 times greater than eye diameter. Clypeus transverse, rounded anteriorly. Palps slender, ultimate palpomeres elongate, ca. 2 times longer than wide; maxillary ultimate palpomere somewhat wider that preceding palpomeres; labial ultimate palpomere considerably wider than preceding palpomeres. Antennae filiform, attaining to elytral five sixths; antennomere 3 ca. 2.4 times longer than antennomere 2 and ca. 1.3 times longer than antennomere 4; antennomeres with short semi-erect pubescence ( Fig. 1 ).

Pronotum transverse, ca. 1.7 times wider than long, basally almost straight, with noticeable tooth before posterior angle; anteriorly slightly convex, but feebly incised medially; medially with broad obscure impression; anterior angles rounded; sides with relatively small hairy ‘cap’, not surpassing one third of side’s length, and almost square oblique opening at posteri- or angle; posterior angle moderately produced, with small spine. Scutellum triangular, rounded at apex ( Fig. 1 ).

Elytra ca. 2.4 times longer than wide at humeri, slightly widened posteriorly, with coarse dense punctuation and traces of two longitudinal veins in sutural halves. Pubescence short and sub-erect, not concealing the punctuation. Femoris and tibiae narrow, straight; ratio of hind leg tarsomeres — 1.3:1:0.7:0.6:1.

Spiculum gastrale very narrow, needle-shaped, parallel-sided. Aedeagus with gradually narrowing distally and conspicuously incised medially ventral plate; dorsal plate broad, trapezoidal, concave at sides before distal angles, with concave and slightly dentate medially anterior margin, denticulate; laterophyses distinctly diverging, curved, acute at apex, not denticulate ( Figs 3–5, 6–11 ).

Female. Similar to male, but pronotum without complex armature, eyes smaller and antennae somewhat shorter ( Fig. 2 ).

Length: 5.0– 5.5 mm. Width (humerally): 1.7–1.9 mm.

DIAGNOSIS. Podosilis cinderella sp.n. resembles P. circumcincta Wittmer, 1997 , also from Yunnan, differing by the uniformly black elytra, as well as by the dentate medially dorsal plate ( Fig. 9 ) and less curved and acute distally laterophyses of the aedeagus ( Figs 4, 7, 10 ).

ETYMOLOGY. The new species is named after the heroine of a fairy tale, alluding to its uniformly black elytra.
