Female. Body length 535. Colour dark brown except antenna mostly, tarsi, ovipositor and wing venation brown and funicle segment 8 and clava lighter in colour (Fig. 1). Head. Width 120. Eye moderate in size, apparently with a few setae (Figs 1, 2). Gena wide, distinct. Maxillary palpi clearly 3-segmented (Figs 1, 2).
Antenna. Funicle segments 3, 5 and 7 distinctly longer than the remainder, and segments 3 and 5 distinctly the widest. Clava with apical segment slightly longer than basal segment. Measurements (length/width) taken from either left or right antenna: scape -/-, pedicel -/-, fl115/15, fl2 28/13, fl3 30/13, fl4 38/13, fl5 38/13, fl6 28/10, fl7 28/15, fl8 25/15, clava (total) 60/18.
Mesosoma. Length 200. Mesoscutum 100, about 1.6 times as long as scutellum (line of demarcation between the two not clear.) Metanotum 23, about ¾ as long as propodeum. Propodeum 30, about 1.2 times as long as metanotum.
Wings. Fore wing narrow, almost parallel-sided (about twice as wide near apex as at narrowest point), the posterior margin with a distinct, rounded lobe at level of base of marginal vein, and longest marginal setae much longer than wing width (Fig. 1). Wing surface without microtrichia, except sparsely in two fairly distinct rows beyond venation. Venation extending well beyond middle of wing. Marginal vein with about 8 setae along its length. Fore wing length/width 406/59, longest marginal setae 112, about 2 times greatest wing width. Hind wing (Fig. 1) narrow and parallel sided, its base not visible but presumably wing membrane not extending to base (as for most Mymaridae). Wing surface without microtrichia. Marginal setae at most about 7 times wing width.
Legs. Tarsi long, probably as long as tibiae (these not clearly visible), and metatarsomere 1 about 1.7 times as long as 2 (Fig. 1). Metatibial spur almost as long as metatarsal segment 3.
Metasoma. Length 225, longer than mesosoma. Petiole (not clearly visible) somewhat narrower than base of gaster. Gaster with segment 1 the longest (of those clearly demarcated). Ovipositor 218 (effective length); ovipositor sheaths slightly protruding beyond apex of metasoma, with several setae along apical third of exposed part (Fig. 1).
