Podosilis holzschuhi Kazantsev , sp.n.

Figs 12–19 .

MATERIAL. Holotype, ♂, N Laos, 20 km NW Luang Namtha, 21°09.2´N, 101°18.7´E, 900–1100 m, 5–30.V.1997, C. Holzschuh leg. ( ICM); paratype, N Vietnam, Sa Pa, 11–18.VI.1990, A. Olexa leg. ( ICM).

Description. Male. Dark brown to black; pronotum, except medially, in lateral hairy ‘caps’, and at anterior and posterior margins, and prosternum testaceous ( Fig. 12 ).

Vertex flat, finely punctate, shining, with short hairs. Eyes small, interocular distance ca. 2.6 times greater than eye diameter. Clypeus transverse, trapezoidal, feebly concave anteriorly. Palps slender, ultimate palpomeres elongate, ca. 2 times longer than wide, considerably wider than preceding palpomeres. Antennae filiform, attaining to elytral five sixths; antennomere 3 ca. 2.6 times longer than antennomere 2 and ca. 1.3 times longer than antennomere 4; antennomeres with short semi-erect pubescence ( Fig. 12 ).

Pronotum transverse, ca. 1.8 times wider than long, basally slightly convex, without tooth before posterior angle; anteriorly convex; medially with inconspicuous longitudinal impression; anterior angles broadly rounded; sides with hairy ‘cap’, constituting ca. half of side’s length, and triangular oblique opening at posterior angle; posterior angle strongly produced into curved spine. Scutellum triangular, broadly rounded at apex ( Fig. 12 ).

Elytra ca. 2.5 times longer than wide at humeri, almost parallel-sided, with coarse dense punctuation and weak 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 — 1:1:0.7:0.6:1.

Spiculum gastrale very narrow, needle-shaped, parallel-sided. Aedeagus with semi-triangular, rounded and inconspicuously incised medially ventral plate; dorsal plate subquadrate, emarginate at sides in the middle, with almost straight and bearing small dent medially distal margin, inner surface bearing prominent teeth; laterophyses distinctly diverging and deeply separated, curved, rounded at apex, denticulate, with a smaller dent apically and a stronger dent at two thirds of their length ( Figs 13–17 ).

Female. Unknown.

Length: 5.5–5.9 mm. Width (humerally): 1.6–1.7 mm.

DIAGNOSIS. Podosilis holzschuhi sp.n. is apparently close to P. donckieri (Pic, 1906) from Yunnan, with the pronotal armature virtually indistinguishable, however, easily separable by the distinctly more narrow ventral plate of the aedeagus with less incised apex, as well as by the more robust apices of the laterophyses ( Figs 13–17 ).

ETYMOLOGY. The new species is named after the collector of the holotype, Dr. Carolus Holzschuh ( Villach , Austria) .

VARIATION. In the paratype the ventral plate of the aedeagus is not incised at apex and the distal margin of the dorsal plate is not dentate in the middle ( Fig. 18 ).
