SCIENTIFIC NAME: Murina Gray, 1842
COMMON NAMES: Tube-nosed bats, tube-nosed insectivorous bats
SYNONYMS: Ocypetes Lesson, 1842 non Risso, 1826 non Wagler, 1829 part.; Harpiola Thomas, 1915.
DIMENSIONS: Body mass 3-13 g, head and body length 33-60 mm, tail length 30-42 mm, forearm length 28-45 mm, wingspan 19-32 cm.
DESCRIPTION: Genus from vespertilionid family, separated into subfamily Murininae. Includes ca. 14 species. Muzzle of moderate length, with characteristic tubular nostrils, which tips are pointed anterolaterally. Ears somewhat funnel-shape, broadly rounded, with elongated sharply pointed tragi. Wings very broad, with elongated thumb. Dentition massive. Small upper premolar similar in shape to posterior premolar, eventually nearly approaching it in size. Two pairs of upper incisors; outer incisor large, with well pronounced supplementary cusps. Pelage thick and wooly, almost completely covering the upper surface of interfemoral membrane and hind limbs up to the toes. Coloration varies from pale grey and light brown to red-brown; underparts usually paler than back. Karyotype includes 44 chromosomes.
DISTRIBUTION: From Southern Siberia and Russian Far East to India, Philippine and Sunda Islands, New Guinea and north-east of Australia.
NATURAL HISTORY: Species of this genus inhabit moist forests, from mixed boreal to tropical rain. Natural history poorly investigated. Roosts situated in various cavities in trees and rocks, tree canopies. Partial ground gleaners, during foraging may use maneuverable relatively slow fight and also quadrupedal ground locomotion. Live solitary or in small groups (rarely can aggregate into wintering colonies of several hundreds). Females give one or two newborns in each litter. Resident species, in the north of distribution area can hibernate.

Two species occur in Russia and neighboring countries:
Greater (or Siberian) tube-nosed bat — M. leucogaster
Ussurian tube-nosed bat — M. ussuriensis
