Artibeus ravus

205. Little Fruit-eating Bat Artibeus ravus French: Dermanure jaunatre / German: Kleiner Fruchtvampir / Spanish: Artibeo amarillento Other common names: Amber Fruit-eating Bat, Yellowish Little Fruit-eating Bat Taxonomy. Dermanura rava G. S. Miller, 1902, “San Javier [Esmeraldas], northern Ecuador.” Artibeus ravus, along with smaller species of Artibeus, 1s placed in Dermanura; however, after reinterpretation of molecular analyses, this clade was reassigned to Artibeus (subgenus Dermanura). Several authors listed A. ravus as a synonym of A. phaeotis, but according to molecular and morphological analyses,it is a distinct species. Monotypic. Distribution. W Colombia (Choco Department and middle and lower Cauca and Magdalena valleys) S through W slope of Andes to SW Ecuador and extreme NW Peru (Tumbes Department). Descriptive notes. Head-body 44-62 mm (tailless), ear 11-17 mm, hindfoot 9-14 mm, forearm 37-42 mm; weight 10-17 g. The Little Fruit-eating Bat is small, with facial stripes and short and broad rostrum. Dorsal fur is light yellowish brown, more pale than dark; fur is short and faintly tricolored (paler bases). Whitish facial stripes are almost well defined but never too contrasting. Ventral fur is slightly paler than dorsum. Ears and noseleaf are pale brown, and bases and margins of ears are usually narrowly rimmed in white or cream. Fur covers more than one-half of each forearm. Wing membranes are brownish and attach to metatarsus. Tail membrane is pale brown, moderated in size, U-shaped, and sparsely haired. Dental formulais12/2,C1/1,P 2/2, M 2/2 (x2) = 28. Skull is elongated, without inflated frontal and supraorbital areas. M' has long hypocone (talon), and M,is always absent. Habitat. Evergreen lowlands and pre-montane forests, second growth, tropical dry forests, fruit groves, and inter-Andean dry valleys from lowlands up to elevations of¢. 2000 m (usually below 600 m). The Little Fruit-eating Bat has broad variation in habitat preferences through its distribution. Food and Feeding. Based on resemblance to congeners and its habitats in western Ecuador, the Little Fruit-eating Bat is assumed to be mainly frugivorous. Breeding. Pregnant and lactating Little Fruit-eating Bats have been found in June-July in Colombia. Activity patterns. The Little Fruit-eating Bat is nocturnal. It is usually more active 2-3 hours after sunset. Movements, Home range and Social organization. No information. Status and Conservation. Not assessed on The IUCN Red List. Additional information on population status and ecology of the Little Fruit-eating Bat is needed for an accurate conservation assessment. Bibliography. Andersen (1908c), Carrera et al.
