( Figs 3 View FIGURE 3 , 4 View FIGURE 4 )

Material examined. Holotype, male, INDONESIA “ Sungai Wain Near Kota Balikpapan , East Kalimantan ”, “ 25.xii.2004 – 3.i.2005 Coll. K. Maeto” and “GRL#5–10”(MZB)

Paratypes. Two males, same data as holotype, one with “GRL#1–1” the other “GRL#1–7” ( MZB).

Length of body 4.3–4.4 mm, fore wing 3.5-3.8 mm, and antenna 4.5 mm.

Head. Antennae with 44–47 flagellomeres. Terminal flagellomere acuminate. Median flagellomeres 1.4 xlonger than wide. First flagellomere 1.0 and 1.1 x longer than 2nd and 3rd respectively, 2.0 x longer than wide. Width of head: width of face: height of eye = 2.4: 1.35: 1.0. Face coriaceous. Inter-tentorial distance: tentorioocular distance = 1.5: 1.0. Malar suture weak, indistinct. Frons deeply impressed postero-medial to antennal sockets, with strong midlongitudinal carina. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.6: 1.0: 3.2.

Mesosoma. Mesosoma 1.2 x longer than high. Median area of metanotum without midlongitudinal carina. Propodeum with a complete midlongitudinal carina.

Wings. Fore wing. Lengths of fore wing veins r-rs: 3 RSa: 3RSb = 1.0: 1.5: 3.7. Lengths of veins 2RS: 3 RSa: rs-m = 1.0: 1.4: 1.1. Base of hind wing without glabrous area next to vein cu-a.

Legs. Claws with acutely pointed basal lobe. Lengths of fore femur: fore tibia: fore tarsus = 1.1: 1.0: 1.1. Lengths of fore femur: fore tibia: fore tarsus = 1.0: 1.15: 1.15. Lengths of hind femur: hind tibia: hind tarsus = 1.0: 1.25: 1.25.

Metasoma. Metasomal tergites 2–5 with coarse reticulate sculpture superimposed on coriaceous background. Tergite 2 with sublateral grooves distinct, straight, converging posteriorly. Second metasomal suture weakly curved, narrow; median length of 3rd tergite 1.05 x 2nd tergite.

Colour. Head and mesosoma largely ochreous yellow, pronotum (largely), and scutellum and propodeum paler, lateral lobes and anterior of middle lobe of mesoscutum darker; metasomal tergites whitish with brown or black medial bands. Wings hyaline with pale brown to dark brown venation; pterostigma brown or black. Front and middle legs ochreous yellow, hind legs largely black except apex of coxa, trochanter and base of tibia.

Female. Unknown.

Host. Unknown.

Distribution. Sungai Wain ( Indonesia).

Etymology. Dedicated to the collector of the type series, Professor Kaoru Maeto, in recognition of his extensive contributions to entomological research.
