Holotype.

Forewing PIN 3840/2602 (the base and most of the anal area missing).

Description.

Forewing ~2.8 mm long, broad (~2.4:1), obliquely rounded apically; costal space moderately narrow, with 3 Sc veinlets; pterostigma wide; RA with break at nodus; R fork rather distal; RP base and crossveins ir1, im1, im2, mcu oblique; ir1 at base of pterostigma; RP section between RP+MA and ir1 desclerotized; MA with terminal fork; 1mp cell single, very long; MP1 4-branched, pectinate backwards; MP2 2-branched; CuA with terminal fork beyond mcu.

Hind wing PIN 3840/2601 (base and most of anal area missing, 1A tucked under), interpreted as a hind wing due to the delicate, finely longitudinally wrinkled wing membrane. Tentatively assigned to the same species on account of similar size, few Sc veinlets, a wide pterostigma, and very long 1mp cell. Hind wing ~2.6 mm long, elongate (~2.8:1), narrowly rounded apically; costal space narrower, probably with 3 Sc veinlets; pterostigma wider, rather evenly suffused, without distinct veinlets; no break on RA; only ir1 somewhat oblique; MA simple; MP1 3-branched; MP2 2-branched; CuA with terminal fork.

Etymology.

Named after the hymenopterist Charles D. Michener.
