Redescription.FEMALE ( lectotypeand paralectotype). Body length 700–744 µm. Body mostly brown to dark brown except base of gaster yellow to light brown; midlobe of mesoscutum with a lighter (light brown) transverse submedian stripe. Appendages light brown to brown. Antenna ( Fig. 47) with short setae. Scape 5.4–6.0 x as long as wide; pedicel much longer than F1; all funicular segments longer than wide; F1–F3 and F5 each subequal in length (F1 the shortest, F5 slightly longer and wider) and shorter than F4, F4 slightly shorter or about as long as F6; F1–F3 and F5 without longitudinal sensilla, F4 and F6 each with 2 longitudinal sensilla; clava about 3.6 x as long as wide, with 5 longitudinal sensilla. Mesosoma shorter than gaster. Midlobe of mesoscutum with 1 pair of strong setae. Wings. Forewing ( Fig. 48) about 5.3 x as long as wide; blade notably infumate behind venation and also slightly infumate in the middle, setose in distal 2/5; longest marginal cilia about 1.4 x greatest width of wing. Hind wing 15–16 x as long as wide; blade infumate; longest marginal cilia 4.2–4.4 x greatest wing width. Metasoma. Ovipositor 4/5 to 9/10 length of gaster, exserted beyond apical gastral tergum by about 1/9 of ovipositor length and not exserted beyond apex of hypopygium, about 1.6 x length of metatibia. Measurements of lectotype(in µm). Body 744; mesosoma 279; gaster 394; ovipositor 321. Antenna: scape (including radicle) 130; pedicel 60; F1 24; F2 30; F3 30; F4 40; F5 36; F6 45; clava 142. The wings are mounted at an angle so that it is impossible to measure them correctly. VARIATION (female, based on the typeand non-type specimens). Body length 700–1600 µm. F 1 invery large specimens (probably from eggs of large hosts) often as long as F2 and about 1/2 length of pedicel (sometimes almost up to 3/4 length of pedicel); F4 of female antenna usually with 2 longitudinal sensilla but rarely with only 1 longitudinal sensillum (and occasionally possibly without such sensilla). Forewing 4.2–5.3 x as long as wide; longest marginal cilia 1.1–1.5 x greatest width of wing. Ovipositor exserted beyond apex of distal gastral tergum by about 1/5–1/12 of its own length and rarely a little exserted beyond apex of hypopygium, 1.2–2.3 x length of metatibia. MALE (based on non-type specimens). Body length 1100–1200 µm. Similar to female except for the normal sexually dimorphic features such as antenna ( Fig. 49), genitalia ( Fig. 51), and the following. Flagellum 11–segmented, all flagellomeres longer than scape. Forewing ( Fig. 50) 3.6–4.7 x as long as wide; longest marginal cilia 1.0–1.6 x greatest forewing width. Gaster shorter than mesosoma.
Diagnosis.Member of the flavovariusspecies group. Among the species with longitudinal sensilla on F4 and a relatively long funicle of the female antenna, E. (E.) picinusis characterized by having the apical 2/5 of forewing blade with numerous setae and a slight, but usually distinct infumation in the middle of the forewing blade. Body size and ovipositor length vary. Proportions of the funicular segments of the female antenna, particularly the length of F1 relative to the pedicel, appear to vary with body size.
Distribution. Canada(new record), Mexico(new record), and USA(including Alaska).
Host. Neurocolpus longirostrisKnight (Miridae)(new record).
Comments.The specimens described by Doutt (1949)as E. flandersiwithout any doubt are just large specimens of E. (E.) picinusthat sometimes have a relatively longer F1 of the female antenna and a slightly shorter F4 apparently bearing just 1 longitudinal sensillum (and occasionally possibly lacking longitudinal sensilla), hence the synonymy. The typeseries specimens of E. flandersiwere slide-mounted without proper clearing and that made it difficult to see the longitudinal sensilla on F4 of the female antenna.
