M a t e r i a l: N Vietnam: Vinh Phuc, Tam Dao N.P. 960 m, at light in village, 1 16-20.IV.2001, leg. de Vries, RMNH´01 (Leiden).

D e s c r i p t i o n of: Body length 21 mm, Flagellum very slightly lanceolate, with 47 flagellomeres. First flagellomere (withour anellus) 2.4x as long as wide, the second one 2.2x, both flagellomeres together 0.64x as long as eye, about the 14th flagellomere square, widest flagellomeres about 1.3x as long as wide. Temple strongly and roundly narrowed. Distance of lateral ocellus from eye 1.4x its diameter. Frons smooth below and rugulose-punctured above. Face and clypeus with strong rugulosepuncture. Temples below with scattered puncture, smooth. Hypostomal carina not elevated.

Mesosoma with whitish hairs, with coarse puncture. Scutellum slightly longer than wide, moderately elevated, without lateral carina. Area superomedia heart-shaped, rugulose, costula behind the middle. Area superoexterna rugulose, area petiolaris with strong lateral carina and transverse striation. Coxa III with a small but distinct scopa, femur III about 4.0x longer than high. Third tarsomere II about 1.6x as long as wide.

Lateral field of postpetiole about 0.7x as wide as the median field, median field striate, with about 10 longitudineal stripes. Thyridium about 1.1x as wide as the thyridial interval, the interval as wide as the median field of postpetiole. Tergites 2 and 3 with coarse puncture, medially striate, tergite 4 with fine puncture, more or less smooth and shining. Apex of metasoma blunt, ovipositor about 0.4x as long as the tergite 7, tergite 7 with long black hairs.

Coloration: black. Yellow are flagellomeres 8-16, palps, sides of clypeus, outer orbits below, inner orbits up to the vertex (widened at frontal orbits and vertex), collare and upper margin of pronotum, subtegular ridge, small spot on lower mesopleurum, two longitudineal stripes on mesoscutum, scutellum and postscutellum, area dentipara, posterolateral marks on tergites 1-5 (largest on tergite 2), spots on coxae I-II and trochanteres I-III, coxa III with anterodorsal and posteroventral marks, apical spots on femora I-III, subbasal rings on tibiae I-III, all tarsi centrally.
