Hairy Fruit-eating Bat Artibeus hirsutus French: Artibée hirsute / German: Haariger Fruchtvampir / Spanish: Artibeo piloso Taxonomy. Artibeus hirsutus K. Andersen, 1906 , “La Salada, Michoacan , Mexico .” Artibeus hirsutus is in subgenus Artibeus . Although usually considered as closer A. inopinatus , molecular analyses suggested that A. hirsutus is sister to A. fraterculus from western South America. Monotypic. Distribution . Pacific slope of Mexico , from C Sonora to Morelos and S Guerrero . Descriptive notes . Head-body 69-90 (tailless), ear 19-24 mm , hindfoot 12-17 mm , forearm 52-58 mm; weight 32-47 g. The Hairy Fruit-eating Bat is externally similar to the Honduran Fruit-eating Bat (A. inopinatus ) of Central America, but larger and with hairier tibia and uropatagium and no conspicuous fringe of hairs on its free edge. Upperparts are pale gray, tips of hairs are frosted silvery, and fur is short and velvety. Whitish facial stripes are inconspicuous, and lower ones are sometimes absent. Ventral furis slightly paler than dorsum. Muzzle is short and broad. Dental formula is 12/2, C 1/1, P2/2,M 3/3 ( x2 ) = 32. Only one of 88 specimens examined lacked M? and M,, but M3 can be absent on one side or both. Cranially, broad spine on posterior border ofpalate projects into interpterygoid space. Chromosomal complement has 2n = 31 (males) or 30 (females) and FN = 56. X-chromosome and Y-chromosome are subtelocentric, and Y,chromosomeis acrocentric. Habitat . Tropical deciduous forests, arid uplands, and occasionally mango and fig groves from lowlands to elevations of 2575 m . The Hairy Fruit-eating Bat is usually netted over streams and water ponds. Food and Feeding . The Hairy Fruit-eating Bat is expected to be frugivorous similar to its congeners. Breeding . Pregnant Hairy Fruit-eating Bats were caught in February—-September (except March) and lactating females in June and August-September. Juveniles were caught in August in Honduras and Nicaragua . Males have descended testes in June. Activity patterns . Hairy Fruit-eating Bats are nocturnal. Known roosts include abandoned mines, small caves, buildings, and beneath boulders. Movements, Home range and Social organization . Hairy Fruit-eating Bats usually roost in small groups. Status and Conservation . Classified as Least Concern on The IUCN Red List. Additional information on population status and life history of the Hairy Fruit-eating Bat is needed to understand its conservation threats. Bibliography .
