Material examined. Holotype female labeled “ ECUADOR: NAPO: Res. Ethnica Waorani, 1km S Onkone Gare Camp, 220m, Trans. Ent. 6 Oct. 1995, 00°39´10´´S, 076°26´W, T.L. Erwin, et al., collectors; Insecticidal fogging of mostly bare green leaves some with covering of lichens or bryophytic plants in terra firme forest. At Trans. 5, Project MAXUS Lot 1213”. Holotype deposited in USNM.

Etymology. masneri (Latinized, noun) = genitive singular, masculine, species named in honor of Lubomír Masner, very good friend and teacher of the first author.

Diagnosis and identification. Ventral margin of clypeus nearly straight ( Fig. 5 ), only minutely produced, all funicular segments longer than broad ( Fig. 4 ), midlobe of mesoscutum and frenum smooth, propodeum with two submedian carinae ( Fig. 6 ), postmarginal vein very short, only twice as long as stigmal vein ( Fig. 9 ), Gt1–Gt4 with posteromedian emargination ( Fig. 7 ), ovipositor only slightly longer than rest of body ( Fig. 1 ).

Description. FEMALE. Holotype. Length of body 1.9 mm, length of ovipositor 2.1 mm. Head, scape, pedicel, mesosoma, and all coxae dark with blue-green metallic tint, but in dorsal view thorax with violet reflections on sides. Flagellum, tegula, femora, tibiae and gaster, including ovipositor sheaths, brown. Tarsomeres 1 and 5 pale brown, 2, 3 and 4 pale yellow. Wings hyaline, slightly infumate, wing venation and setae from pale brown to dark brown.

Head. 1.2X as broad as high; 1.9X as broad as long; 1.2X broader than mesoscutum in its widest part in dorsal view; HTE:LTE = 1.3; HTE:MSP = 2.7. Temples extremely short, 0.1X LTE. Ventral margin of clypeus nearly straight ( Fig. 5 ). Mouth 1.7X length of MSP. Scape 6X as long as width of basal part, curved along whole length ( Fig. 8 ). Antennal segments with relative measurements = 18:5:0.5:7:6.5:6:6:5:5:5:13; pedicel 1.3X, anellus 0.3X, F1 2.8X, F2 2.2X, F3 1.5X, F4 1.5X, F5 1.3X, F6 1.1X, F7 1.0X, and clava 2.4X as long as broad. Ocelli relatively large, POL 2X OOL, the latter 1.2X OD.

Mesosoma. Mesonotum twice as long as broad. Dorsal part of pronotum 1.5X as broad as long; with irregularly serrate sculpture, lateral panels of pronotum alutaceous and distal third of pronotum more or less smooth. Mesoscutum 1.6X as broad as long, with anterior half of midlobe conspicuously reticulate and posterior part smooth, but sidelobes alutaceous. Axillae alutaceous. Scutellum nearly as broad as long, flattened; strongly reticulate in anterior two-thirds, frenal area smooth ( Figs 6, 7 ). Propodeum smooth and mostly shiny, with two complete submedian carinae and row of foveae anteriorly and posteriorly. Mid tibia with spur relatively long, 1.9X width of tibia. Hind tibia with longer spur 1.4X as long as shorter spur. Forewing 2.8X as long as wide; relative measurements, marginal:postmarginal:stigmal vein = 25:3:1.5; stigmal vein short and dark brown ( Fig. 9 ).

Metasoma. About as long as mesosoma; gaster 1.3X as long as high. Gt1–Gt4 deeply emarginated. Ovipositor 2.5X as long as metasoma, ovipositor index 3.9 ( Fig. 1 ).

MALE. Unknown.

Biology. Unknown. The label data only states that the specimen was collected by insecticidal fogging of mostly bare green leaves, some with a covering of lichens or bryophytic plants in terra firme forest.

Distribution. Known from only one specimen from Ecuador.
