2. Large Long-fingered Bat Miniopterus magnater French: Grand Minioptere / German: Malaiische Langfligelfledermaus / Spanish: Miniéptero grande Other common names: Large Bent-winged Bat, Western Bent-winged Bat, Western Long-fingered Bat Taxonomy. Miniopterus schreibersii magnater Sanborn, 1931, “Marienberg, forty miles up the Sepik River, Territory of New Guinea,” Papua New Guinea. Miniopterus magnater is somewhat larger than species in the schreibersii complex, and preliminary genetic studies have confirmed that it is well differentiated from other Asian forms previously included in that complex, but they also seem to indicate that populations assigned to M. magnater from South-east Asia are very different from those in New Guinea. Detailed genetic study is necessary to clarify taxonomyin this lineage. Monotypic. Distribution. NE India (Meghalaya), S China (including Hong Kong and Hainan I), most of mainland SE Asia, Sunda Is (Sumatra, Borneo, Java, Nusa Penida, and Timor), and C Moluccas (Seram and Ambon Is) to New Guinea; it may occur in Bangladesh. Descriptive notes. Head-body 58-75 mm, tail 52-64 mm, ear 11-17 mm, hindfoot 9-13 mm, forearm 48-54 mm; weight 11-3-21-3 g. Pelage of the Large Long-fingered Bat 1s thick, soft, almost uniform black to dark brown, and unicolored on dorsum; hairs on chest have pale tips becoming uniform pale gray-brown on abdomen. Pelage occasionally has reddish patches or is even completely reddish. Ears are small, and tragus is short (5-7 mm), blunt, and curved slightly forward. All exposed skin including membranesis black-brown to black. Diploid numberis 2n = 46 (Sabah, Borneo). Habitat. Major habitats include human settlements; open land; disturbed secondary woodlands with bamboo; cocoa, coffee, and banana plantations; and pristine forests from sea level to elevations of ¢. 1500 m in Borneo and ¢. 2100 m in New Guinea. Food and Feeding. The Large Long-fingered Bat generally forages on insects captured in flight above canopies and also low over streams and small water bodies. It forages for insects around streetlights. No details on diet are available. Breeding. In New Guinea, ten female Large Long-fingered Bats captured in July were reproductively inactive, but six females captured in mid-August each carried one halfdeveloped fetus. Activity patterns. The Large Long-fingered Bat is thought to be mainly nocturnal. It is cave dwelling. Echolocation calls have downward FM signals. Mean call characteristics in Thailand are start frequency 85-3 kHz, end frequency 42-3 kHz, peak frequency 47-4 kHz, duration 4-3 milliseconds, and interval 65-2 milliseconds. Movements, Home range and Social organization. Colonies in caves usually have a few hundred individuals but can reach up to several thousand. Large Long-fingered Bats usually share roosts with other cave-dwelling bats (Taphozous, Hipposideros, Rhinolophus, Miniopterus, etc.). Status and Conservation. Classified as Least Concern on The IUCN Red List. Bibliography. Akmali et al. (2015), Bates et al.
