Scutoscutellar sulcus with five foveae; mesodiscrimen with about 10 strong foveae; median longitudinal carina on dorsal part of propodeum present, smooth area on postero-lateral part of propodeum present.

Canada: 1f, Gatineau Park, Quebec, 16 VII 1991. K. Yamaghishi (ELMU); 1f, Ontario, E. Griffith, 7mi, 19 VII 1940, B. E. Cooper (ELMU). USA: 1f (15–21 V 2011), 4f (22–28 V 2011), and 2f (29 V –4 VI 2011), VA, Fairfax Co., Holmes Run ~1/ 4mi NE, jct, Gallows Rd & I-495, 38°50’N, 77°12’W, MT, D. R. Smith (SEHU); 1f, VA, Prince William Co., Bull Run Mtns, Chestnut Ridge Trail, 38°49.6’N, 77°42.4’W, MT, 25 VI–7 VII 2011, D. R. Smith (SEHU); 2f, VA, Fairfax Co. near Annandale, MT, 11 VI 1988, David R. Smith (NSMT). Host. Isorhipis ruficornis (Say, 1823) (Muona 2021). Distribution. Canada (Hogan et al. 2019), USA (Timokhov & Belokobylskij 2020). Remarks. This species was erroneously recorded from South Korea (Choi & Lee 2012). We examined the voucher specimen deposited in YNU and identified it as V. yurii (as preliminary suggested by Timokhov & Belokobylskij, 2020). Thus, V. eucnemidarum is not part of the vanhorniid fauna of South Korea.
