(gures 20, 21)

Female. Body length 2.1 mm. Body black; antenna brown, excepting scape and pedicellus deep yellow; coxae, legs, tibiae reddish brown.

Head in front view, clypeal margin emarginate, gena strongly exceeding mouth. Antennal insertion above clypeal margin; antenna (gure 20) with scape not reaching the median ocellus; pedicellus about twice as long as broad, and longer than rst funicular segment; rst funicular segment much shorter than the second; the second quadrate, the fth transverse; clava about 1.8 times as long as broad; agellum plus pedicellus shorter than head width. Relative measurements: head width 52, height 37, length 21, eyes height 18, scape 18, POL 5 OOL as 16 5 5.

Thorax convex; pronotum narrower than mesoscutum, collar not margined; notauli deep and complete; scutellum without frenal line; propodeum with slightly tooth-like median carina, nucha distinct. Fore wing (gure 21) densely hairy, without speculum. G aster sessile, ovate, rst gastral tergite about three- fths length of gaster. Relative measurements: pronotum length 5, mesoscutum length 23, scutellum 31 long and 29 wide, fore wing length 110, width 48, marginal vein 10, postmarginal 11, stigmal vein 10; gaster width 55, length 71.

Male. Unknown.

E. aequalivena is very similar to E. strenus except for the marginal vein as long as the stigmal (gure 21); POL 5 OOL as 3 5 1. E. strenus with marginal vein about 1.5 times as long as the stigmal (gure 19); POL 5 OOL as 4 5 1.
