Podosilis zaitsevi Kazantsev , sp.n.

Figs 35–38 View Figs 35–43 .

MATERIAL. Holotype, ♂, Vietnam, Gialai-Kontum , Buon-Loi, 1–5.I.1990, Yu. Zaitsev leg. ( ICM).

Description. Male. Dark brown to black; frons, clypeus, pronotum, except in lateral hairy ‘caps’, and at posterior margin, and prosternum testaceous ( Fig. 35 View Figs 35–43 ).

Vertex finely punctate, shining, with a pair of small round impressions, with short hairs. Eyes small, interocular distance ca. 2.9 times greater than eye diameter. Clypeus transverse, rounded anteriorly. Palps slender, ultimate palpomeres elongate, considerably longer and wider that preceding palpomeres. Antennae filiform, attaining to elytral five sixths; antennomere 3 ca. 2.3 times longer than antennomere 2 and ca. 1.4 times longer than antennomere 4; antennomeres with short semi-erect pubescence.

Pronotum transverse, ca. 1.7 times wider than long, basally straight, without tooth before posterior angle; anteriorly slightly convex; medially with inconspicuous narrow longitudinal impression; anterior angles rounded; sides with hairy ‘cap’, constituting less than half of side’s length, posterior opening almost obsolete; posterior angle moderately produced. Scutellum almost parallel-sided, rounded at apex ( Fig. 35 View Figs 35–43 ).

Elytra ca. 2.5 times longer than wide at humeri, slightly widened posteriorly, 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 — 1.2:1:0.7:0.8:1.

Spiculum gastrale very narrow, needle-shaped, parallel-sided. Aedeagus with abruptly narrowing distally in distal half and conspicuously incised medially ventral plate; dorsal plate broad, with two broadly separated lobes; laterophyses parallel-sided, almost straight, narrowing distally, not denticulate ( Figs 36–38 View Figs 35–43 ).

Female. Unknown.

Length: 5.4 mm. Width (humerally): 1.7 mm.

DIAGNOSIS. Podosilis zaitsevi sp.n. resembles P. annamita (Pic, 1928) from south Vietnam, differing by the noticeably shorter overlapping ‘cap’ of the pronotal armature ( Fig. 35 View Figs 35–43 ), as well as by the parallel-sided, approximate and not pointed apically laterophyses of the aedeagus ( Figs 36–38 View Figs 35–43 ).

ETYMOLOGY. The new species is named after the collector of the type specimen, Dr. Yurij Zaitsev (Moscow) .
