Diagnosis. Member of the agilis species group ( Triapitsyn 2003). This species is similar to the Palaearctic species E. (E.) magnus S. Triapitsyn and E. (E.) soykai Donev , from which it differs by the morphological features given in the key by Triapitsyn (2003). Females of E. (E.) agilis are characterized by the following: body coloration dark brown, except midlobe of mesoscutum with a narrow, light brown, transverse, submedian stripe, and with basal two terga of the gaster and the base of the third gastral tergum yellow; antenna ( Fig. 4 ) slender, with a long scape, F1 about as long as or only slightly longer than the pedicel, F4 and F6 each with 2 longitudinal sensilla, and clava with 6 longitudinal sensilla; forewing ( Fig. 5 ) 4.3–5.3 x as long as wide, the longest marginal cilia 0.95–1.00 x greatest forewing width, the blade more or less uniformly, densely setose in apical half; hind wing about 20 x as long as wide; ovipositor about 4/5 length of gaster, a little exserted beyond apical gastral tergum (by about 1/10–1/6 of ovipositor length), 0.9–1.3:1 x length of metatibia. Males of E. agilis are similar to females except for the normal sexually dimorphic features: all flagellomeres of the antenna longer than scape, forewing slightly wider than in female, and genitalia occupying about 1/2 length of gaster.

Distribution. Canada and USA (new records) as well as Belgium, Denmark, England ( UK), Finland, Germany, Italy, Kyrgyzstan, Netherlands, Norway, Russia, Sweden, and Switzerland ( Triapitsyn 2003), and also Bulgaria, Greece, Macedonia, and Serbia ( Donev 2004).

Host. Leptopterna dolabrata (Linnaeus) (Miridae) ( Triapitsyn 2003).
