E. nilssonii parvus: Ellerman & Morrison-Scott, 1951 p.155; Won, 1958 p.457; Won, 1967 p.336; Won, 1968 p.120; Corbet, 1978 p.57 (doubtful); Yoshiyuki, 1989 p.168; Yoon, 1992 p.48; Yoon, 2010 p.65.

Range: The distribution of E. nilssonii ranges throughout the Korean Peninsula, but the species remains rare in southern Korea (Han et al. 2011; Fig. 35). The northern bat was first recorded in Lanam, Hamgyeongbuk Province and observed in the area surrounding Seoul and Gyeonggi Province (Won 1967; Son 2001; Kim et al. 2015).

Remarks: Only the Subspecies Eptesicus nilssonii parvus Kishida, 1932 was recognized for Korea (Won 1968; Yoon 2010). Although Hanák and Horáćek (1986) regarded this subspecies as an erroneous identification of Pipistrellus savii, Yoshiyuki (1989) classified E. nilssonii from Sakhalin and Hokkaido to E. n. parvus .
