F756B449E5CDFDB748F8A0F282566543.taxon	diagnosis	Diagnosis. Eurytenes abnormis is most readily recognized by the pale coloration of the petiole and metasoma and is further distinguished from the four North American species described below by the narrower, more ventrally concave clypeus (Fig. 10). The petiole is narrower than in Eurytenes dichromus, sp. n. and Eurytenes microsomus, sp. n. and is thus more similar in shape to the darker Mexican species described below.	en	Walker, Andrea K., Wharton, Robert A.

F756B449E5CDFDB748F8A0F282566543.taxon	distribution	Distribution. Previously recorded from throughout most of Europe (specifically Austria, Belgium, Bulgaria, Croatia, England, Finland, Germany, Hungary, Ireland, Italy, Lithuania, Poland, western Russia as far as the Urals, and Ukraine). Also recorded from eastern Palaearctic (Korea and Sakhalin Island), central to eastern Canada (Ontario, Saskatchewan) and USA (Minnesota, Missouri, North Dakota, South Carolina). Specific references to individual records can be found in Yu et al. (2005) for the most part; the record from the Urals is from Tobias and Jakimavicius (1986). Fischer (1970) recorded Eurytenes abnormis from Montana; however, the specimen on which it is based was collected in Missouri (label information only indicated the state as Mo.). The records from Sakhalin (Tobias 1998) and Korea (Papp 1985) may need to be verified in light of other species described from that general region. The specimens we have examined from Taiwan and the Kuril Islands differ in wing venation, body coloration, and sculpture from typical Eurytenes abnormis. Papp (1985) also noted the darker coloration of the petiole of his Korean specimen.	en	Walker, Andrea K., Wharton, Robert A. (2011): A review of New World Eurytenes s. str.

75378FFC78D6060DBA5151E019FCD1C3.taxon	diagnosis	Diagnosis. This species is most readily recognized by its broader, bicolored petiole and bicolored, ventrally truncate clypeus. Based on the shape and color pattern of the petiole, as well as the shape of the clypeus, Eurytenes dichromus is most similar to Eurytenes microsomus, sp. n. The propodeum is nearly always more heavily sculptured in Eurytenes dichromus than in Eurytenes microsomus and usually slightly more rugulose posterior-laterally than in Eurytenes abnormis.	en	Walker, Andrea K., Wharton, Robert A.

Metasoma with T 2 and T 3 brown, middle tergites with brown and yellow transverse banding, apical tergites yellow. Legs yellow except hind tibia butterscotch to weakly infuscate, tarsus entirely medium brown. Wings largely hyaline, though appearing very slightly darker than other species treated here. Male. Same as female except length of body 2.9 - 3.1 mm (m = 3.0), length of fore wing 3.1 - 3.7 (m = 3.4). Antenna with 34 - 38 flagellomeres; first flagellomere length 2.3 - 3.0 x width (m = 2.8), fifteenth flagellomere length 2.0 - 2.35 x width (m = 2.25), fifth from last flagellomere length 1.8 - 2.2 x width (m = 2.1). Face 1.9 - 2.1 (m = 2) x wider than high. Clypeus 1.7 - 3.0 (m = 2.3) x wider than distance between clypeus and eye. Precoxal sulcus shape variable, generally narrowing anteriorly and widening ventral-posteriorly. 1 - 3 longer, somewhat decumbent setae extending posteriorly from notaulus on mesoscutal disc. Fore wing r-m mostly unpigmented, usually tubular throughout (with lateral boundaries distinct). Hind wing m-cu usually extending more than half way to wing margin as a weakly pigmented, spectral impression. Hind tibia 7.4 - 8.5 (m = 7.9) x longer than maximum width. Petiole 2.1 - 2.7 (m = 2.35) x longer than apical width. Head and petiole dark reddish-brown to black; hind tibia usually more distinctly brown; tergites butterscotch with transverse bands of medium brown on T 2 - T 4 and uniformly medium brown on T 5 and following.	en	Walker, Andrea K., Wharton, Robert A.
