418. Brandt's Myotis Myotis brandtii French: Murin de Brandt / German: GroRe Bartfledermaus / Spanish: Ratonero de Brandt Other common names: Brandt's Bat Taxonomy. Vespertilio brandtii Eversmann, 1845, Orenburgsk, Russia. Subgenus Pizonyx; brandtii species group (2 species). See M. sibiricus. Monotypic. Distribution. N & C Europe from S Fennoscandia and Great Britain to SE Europe and W Siberia, isolated populations in C Italy, Turkey, Caucasus, and C Asia. Exact distribution is uncertain because of confusion with field identification with the Common Whiskered Myotis (M. mystacinus). Descriptive notes. Head-body 39-51 mm, tail 32-44 mm, ear 12-17 mm, hindfoot 7-9, forearm 33-38- 2 mm; weight 5-7 g. Brandt's Myotis has remarkably long and wide-spaced ears, resembling its sister species, the Common Whiskered Myotis. It lacks postcalcariallobe to membrane. Fur is typically brownish or blackish, with golden tips. Venteris only slightly paler than dorsum. Brownish color becomes more evident with age; juveniles are almost completely black. Bare skin is darker than on other species such as Daubenton’s Myotis (M. daubentonit). Male Brandt's Myotis can be easily distinguished from other cryptic species such as the Common Whiskered Myotis by its uniformly thinner penis. Skull is slender and delicate, but large with flat frontal and parietal regions. I* has shallow groove or tiny protuberance on palatal edge of cingulum; P? and P, are comparatively robust and high, P, usually reaching two-thirds height of P,; P_ is slightly intruded from tooth row; paraconules are usually present on molars. Chromosomal complement has 2n = 44 and FNa = 52 (Germany). Habitat. Mixed, coniferous, and broadleaf forests, usually close to aquatic habitats such as swamps, lakes, moors, or damp areas, from sea level up to elevations of ¢. 1800 m. In the southernmost part of its distribution, Brandt's Myotis is more commonly found in the mountain areas. Food and Feeding. Although Brandt's Myotis feeds close to aquatic habitats, it feeds on ...
