White-lined Broad-nosed Bat

Platyrrhinus lineatus

French: Sténoderme rayé / German: \WeiRlinien-Breitnasenfledermaus / Spanish: Platirrino rayado

Other common names: \ White-lined Bat

Taxonomy. Phyllostoma lineatum E. Geoffroy Saint-Hilaire, 1810 ,

“ Paraguay.” Restricted by A. Cabrera in 1958 to Asuncion, central Paraguay.

Platyrrhinus nigellus was previously included as a synonym of P. lineatus but is now a junior synonym of P. umbratus . Isolated population of P. lineatus in southern Suriname 1s molecularly indistinguishable from populations in the rest of the distribution. Monotypic.

Distribution. Disjunct distribution, S Suriname and French Guiana and in E, C & S Brazil, N & E Bolivia, Paraguay, N Uruguay, and NE Argentina.

Descriptive notes. Head-body 60-78 mm (tailless), ear 15-21 mm, hindfoot 10-15 mm, forearm 43-50 mm; weight 18-28 g. The White-lined Broad-nosed Bat is a medium-sized species of Platyrrhinus . Dorsal pelage is medium to dark brown, and ventral pelage is paler. Dorsal and ventral fur is distinctly tricolored. White, prominent median dorsal strip runs from top of head to rump. Two pairs of conspicuous white facial stripes are evident: one pair supraocular from base of horseshoe of noseleaf to top of head and one subocular from commissure of mouth to base of ears. Noseleaf is simple, brown, and yellowish on edges of horseshoe, base of spear, and bases and borders of ears. Tops of feet have long, dense hair. Uropatagium is short, and posterior margin is fringed with dense short hairs along the edge. Dental formula for all species of Plutyrrhinusis 12/2, C171, P 2/2, M 3/3 (x2) = 32. I ave in contact, and I? can be unilobed or bilobed. P? are slightly larger than one-halfsize of P*. Well-developed metaconid is present on M,. Chromosomal complement has 2n = 30 and FN = 56.

Habitat. Atlantic Forest and adjacent ecoregions, including arid cerrado and caatinga, savanna formations, secondary forests, and urban areas at elevations of 100-1000 m.

Food and Feeding. The White-lined Broad-nosed Bat primarily eats fruit but is also known to eat insects, nectar, and leaves of Solanum spp. ( Solanaceae ). In north-eastern Brazil, a colony fed on seven plant species including pioneering and exotic species.

Breeding. In open xeric caatinga and cerrado of north-eastern Brazil, an extended period of pregnancy begins early in dry season (July) and ends in rainy season (February—March). There is bimodal polyestry, with primary peak in October and secondary peak in January. Females wean their young primarily during beginning and then end of wet season.

Activity patterns. The White-lined Broad-nosed Bat is most active two hours after sunset, with a second smaller peak around midnight. Highest rates of capture occurred in first one-half of rainy season (October-November), with an increase in February, in southeastern Brazil. It roosts in small caves and under leaves of palms and other plants.

Movements, Home range and Social organization. Male White-lined Broad-nosed Bats might have small harems of 7-15 females. Colonysizes of up to 75 individuals have been reported.

Status and Conservation. CITES Appendix III ( Uruguay). Classified as Least Concern on The IUCN Red Last.
