Platyrrhinus ismaeli is a species of bat found in South America.
It is a medium-sized member of its genus, with a forearm length of 50–56 mm (2.0–2.2 in) and a body mass of 30–51 g (1.1–1.8 oz).The fur on its back is dark brown, and its ventral fur is grayish.It has dark facial stripes of differing sizes.It has a stripe running down the length of its spine that is lighter than its facial stripes.Its nose-leaf is longer than it is wide.Males and females are similar in appearance.
It has been documented on both sides of the Andes in Peru, Ecuador, and Colombia.It occurs at relatively high elevation, from 1,230–2,950 m (4,040–9,680 ft) above sea level.It is often found in montane forests.
Little is known about its reproduction. A pregnant female was once documented in late January, while another female with more advanced pregnancy was documented in early March.It is "basically frugivorous".
It is currently evaluated as near-threatened by the IUCN.Its most recent assessment in 2016 was a down-listing from its 2008 assessment as vulnerable.It meets the criteria for near-threatened because its habitat quality and extent is decreasing rapidly, which may negatively affect its population.While there was a suspected population decline from 2001–2015, it is suspected that it was less than 30%.
