Figs 19, 20 , 33 , 52, 53 , 78

Diaulus begini Ashmead, 1904: 356 , female holotype in USNM, not seen. Solenotus begini ; Hills & Taylor, 1951: 760 –762.

Diglyphus begini ; Peck, 1963: 103.

Diagnosis. Scape dark ( Figs 52, 53 ); legs ( Fig. 33 ): femora dark with apical ¼–⅓ yellowish-white; fore tibia yellowish-white, sometimes with posterior surface infuscate, mid and hind tibiae yellowish-white with a dark ring basally—this ring can occasionally be very weak and is missing in a few specimens; fore wing speculum bare or with a few scattered setae (as in Fig. 72 ); male gaster completely dark ( Fig. 20 ).

Material. Croatia: 1♀ ( BMNH) . Denmark: 1♀ ( BMNH) . Norway: 21♀ & ♂ ( BMNH) . Finland: 1♀ ( BMNH) . France: 2♀ ( BMNH) . Germany: 1♀ ( BMNH) . Hungary: 3♀ ( BMNH) . Russia: 2♀ ( ZISP) . Sweden: 389♀ & ♂ ( BMNH, MZLU) .

The specimens from Sweden, identified as D. chabrias in Hansson (1987) , were misidentified, instead they are D. begini .

Distribution. Croatia *, Czech Republic ( Kalina 1989), Denmark *, Finland *, France *, Germany *, Hungary *, Norway ( Hågvar et al. 1994), Peoples' Republic of China ( Zhu & Huang 2001), Russia *, Slovakia ( Kalina 1989), Spain (Canary Islands) ( Koponen & Askew 2002), Sweden *, Turkey ( Gencer 2009), Yemen (Yefremova 2007). This species was originally described from Canada and it is one of the most abundant species in North America ( Gordh & Hendrickson 1979). It is also recorded from South America ( Brazil, Colombia, Peru) ( Noyes 2016).
