Platyrrhinus albericoi

French: Sténoderme dAlberico / German: Alberico-Breitnasenfledermaus / Spanish: Platirrino de Alberico

Taxonomy. Platyrrhinus albericoi Velazco, 2005 ,

“ San Pedro, Paucartambo-Pilcopata road, 1480 m in elevation, Province of Paucartambo, Department of Cuzco, Peru, ap-proximately 13°0'1" [sic] S, 71°32'46" [sic] WwW”

Platyrrlunus albericot was distinguished from P. vittatus based on morphological and molecular studies, but information as-sociated to these two speciesisstill confus-ing. Monotypic.

Distribution. N & W Venezuela, Colombia, Ecuador, E Peru, and N Bolivia.

Descriptive notes. Head-body 90-100 mm (tailless), ear 24-25 mm, hindfoot 15-16 mm, forearm 57-63 mm; weight 55-68 g. Alberico’s Broad-nosed Bat is one of the largest species of Platyrrhinus . Fur is dense and soft. Dorsal fur is blackish brown and long (8 mm); hairs on back and underparts are tricolored; dorsal line on mid-back is snow white and narrow from crown to base of caudal membrane; and underparts are grayish brown to light brown, paler than back. Head is robust, short, and broad. Face has four parallel stripes, snow white and conspicuous; upper ones run from behind nose over eyes to upper edges of ears on crown; lower ones are less sharply defined and run from upperlip under eyes to lower edges of the ears. Noseleat is fleshy, large, and spear-shaped; edges of noseleaf are dark, never bright yellow, and lower rim is free; ears are large and rounded, edges sometimes pale, but never yellow; and folds on ears are poorly marked but distinguishable along rear edge. Length of third metacarpal is subequal to fifth; elbows are densely furred and colored like back. Caudal membrane is very short in middle, with deep V-shaped groove; edge has dense fringe of short hairs; and hairs on upper surface of feet are long and dense. I' are broad and converging, with parallel tips, and twice as long as I>. M' mesostyle is present, M* metastyle is absent, and stylid cusps are absent on anterior or anterolingual face of main cone of P,. Chromosomal complement of 2n = 30 and FN = 56 reported for Greater Broad-nosed Bat ( P. vittatus ) might have been based in part on specimens of Alberico’s Broad-nosed Bat.

Habitat. Tropical, subtropical, and temperate forests in montane humid and cloud forest at elevations of 450-3220 m (mostly 1000-2000 m). Alberico’s Broad-nosed Bat is found in primary, secondary, altered, and gallery forests and at forest edges near cultivated areas.

Food and Feeding. No information but presumably frugivorous.

Breeding. In Ecuador and Peru, pregnant Alberico’s Broad-nosed Bats were found in January-March and August and lactating females in March and September—October. In Ecuador, a scrotal male was found in October. These data suggest postpartum estrus and bimodal polyestry.

Activity patterns. Alberico’s Broad-nosed Bat is nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. In Bolivia, Alberico’s Broad-nosed Bat has been classified as near threatened due its presence in a highly fragile ecosystem (Yungas). It is fairly common,its conservation status is apparently stable, and it occurs in several protected areas.
