(Kinsey, 1929)

Besbicus is a genus of gall-inducing cynipid wasp found in North America. Several species now classed as Besbicus were formerly considered to be a part of the genus Cynips. Besbicus was originally described as a subgenus by Alfred Kinsey in 1929. Circa 2010, one group of entomologists noted that it was "possible that the nearctic genera Antron and Besbicus were erroneously synonymized to Cynips".
