Range: Previous records of N. furvus clustered in northern Korea, but recent collections came mostly from central and southeastern Korea (Son 2001; Yoon 2010; Fig. 32).
Remarks: Nyctalus noctula motoyoshii is considered a synonym of Nyctalus furvus (Fukui 2009a). Formerly, two subspecies of N. noctula (motoyoshii and namiyei) were reported from Korea (Won 1967). Although Won (1967) considered N. n. namiyei as Vespertilio namiyei and Corbet (1978) changed N. n. motoyoshii to V. superans, both subspecies were regarded as synonyms of Vespertilio sinensis (Fukui 2009a, b). Recently, the taxon N. n. motoyoshii was transferred from V. sinensis to N. furvus (Fukui 2009a). Although previous records of N. n. motoyoshii in Korea were doubtful (no voucher specimen; Won 1968), N. furvus has appeared on the list of Korean bats since the first record (or re-discovery) in 1995 (Yoon 2009). Nyctalus n. namiyei is considered a synonym of Vespertilio sinensis.
Conservation status: Maeda and Sano (2008) regarded N. furvus as an endemic species in Japan and listed the species as ‘Vulnerable’ based on Japanese populations. As in Japan, only a few records of N. furvus have been reported in Korea.
