495. Far Eastern Myotis Myotis bombinus French: Murin bourdon / German: Ostliche Fransenfledermaus / Spanish: Ratonero abejorro Taxonomy. Myotis nattereri bombinus Thomas, 1906, Japan, “Tano, Miyasaki Ken, Kiushiu [Japan]. 300’ [= 152 m].” Subgenus Myotis; myotis species group. Myotis bombinus is often included as a subspecies of M. nattereri, but genetic data place it closer to M. pequinius and possibly M. schaubi, M. chinensis, and M. escalarai than to M. nattereri, although some genetic studies found differing relationships. It has been suggested the amurensis is a distinct species. Two subspecies recognized. Subspecies and Distribution. M.b.bombinusThomas,1906—NCMongolia,SWRussia,NEChina(HeilongjiangandJilin),andKoreanPeninsula(includingJejuI). M. b. amurensis Ognev, 1927 — much ofJapan (including Kuchinoerabu-jima I).

Ears are long and narrow, with narrow tips; tragus is long, narrow, and markedly recurved. Uropatagium has stiff bristles at back margin, and membraneitself is surprisingly thick for the genus. Wing attaches to bases of toes, and calcaris long, lacking postcalcariallobe. Skull is long and robust, with comparatively long braincase and short rostrum; and small P? is in tooth row orslightly intruded from it. Chromosomal complement has 2n = 44 and FNa = 50 (Japan). Habitat. ‘Temperate forests at low and high elevations. Far Eastern Myotis reportedly forage in woodland habitats. Food and Feeding. Diet consists mainly of Lepidoptera, Coleoptera, Diptera, Trichoptera, and Araneae. Far Eastern Myotis can hover in flight and generally fly less than m aboveground when foraging. Breeding. Far Eastern Myotis are seasonally monoestrous. Copulation takes place in autumn before hibernation, with ...
