(Figs 3, 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.
