Material examined.

Holotype female, Thailand, Nam Province, Doi Phu Kha N P, office 19°12.458'N, 101°4.866'E, 1359 m, 29.xi.2007, coll. Charoen & Nikom collection code T3259, DNA voucher BCLDQ01600 (QSBG).

Morphology.

Length of body 5.5 mm, fore wing 6.0 mm, of antenna 12.0 mm and of ovipositor 1.1 mm.

Head. Antenna with 63 flagellomeres. Mesian flagellomeres approximately 3.7 × longer than wide.First flagellomere 1.3 × longer than both the 2nd and 3rd separately. Face with fine transverse striation angled upwards medially. Height of eye: width of face: width of head (across eyes) = 1.42: 1.0: 2.3. Frons, vertex and occiput shiny. Frons with depressions on either side just in front of anterior ocellus. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance from posterior ocellus and eye = 1.0:2.0:2.0. Back of head with a distinct longitudinal groove running between occipital carina and posterior ocellus; with crenulation along whole of anterior edge of occipital carina.

Mesosoma. 1.05 × longer than tall. Scutellar sulcus with 5 strong carinae between the outer ones. Propodeum with distinct small medio-lateral tooth-like process.

Fore wing. Lengths of veins r:3-SR:SR1 = 1.0:3.5:5.7. Vein 3-SR approximately 2.5 × length of r-m. Vein cu-a strongly curved. Vein 2-CU1 approximately 5 × length of 1-CU1, the latter distinctly thickened.

Legs. Lengths of fore femur : tibia: tarsus: basitarsus = 1.9: 2.0: 2.25: 1. Lengths of hind femur: tibia: tarsus = 1.0: 1.2: 1.25. Hind basitarsus equal in length to tarsal segments 2, 3 and 4 combined and approximately 10 × longer than maximally deep.

Metasoma. Tergites 1-5 strongly foveolate. 1st tergite approximately 1.4 × longer than maximally wide; 2.3 × wider posteriorly than at its narrowest. Tergite 2 1.5 × wider than medially long; 1.4 × longer than 3rd. 2nd suture weakly bisinuate, wide.

Coloration. Antennae yellow basally becoming dark apically, the pale segments narrowly spotted black at apex. Head brown yellow becoming black posterodorsally including stematicum and centre of frons. Mesosoma largely black, pronotum and anterior of mesoscutum white, propodeum brown yellow. Wings with a broad smokey transverse band and small smokey grey patch at apex; venation yellow in parts where membrane not pigmented, black where membrane is smokey, including whole of pterostigma. Legs yellow with white coxae, but with hind femur largely black. Metasoma largely white but posterior of tergite 1 narrowly, and all of tergites 2+3 black.

Etymology.

Based on the confusing combination of characters.
