Genus Hypsugo Kolenati, 1856

Hypsugo was once regarded as a Subgenus of Pipistrellus (Simmons 2005), although Horáček and Hanák (1986) viewed Hypsugo as a distinct genus (followed by Juste & Paunovic 2016). Genetic and karyological analyses did not support a close relationship between Pipistrellus and Hypsugo (Kruskop 2012) . One species, H. alaschanicus occurs in Korea. With Vespertilio, Hypsugo represents the Tribe Vespertilionini in the Subfamily Vespertilionae .
