Burton's yellow-shouldered bat

Burton's yellow-shouldered bat (Sturnira burtonlimi) is a species of leaf-nosed bat known from Panama and Costa Rica. It was described as a new species in 2014, and its name honors Burton K. Lim, who collected the holotype in March 1995; the describers called him a tireless fieldworker whose research has contributed much to understanding of the diversity, relationships and biogeography of tropical mammals. The bat is medium-sized for its genus, with a forearm about 44 millimeters long and a weight of about 19 grams. The fur on its back is dark brown, with each hair banded in four colors, pale gray nearest the body, then dark gray, pale gray again and a dark brown tip, while the belly fur is also dark brown with tricolored hairs. It has 32 teeth. The species was first documented north of Santa Clara in Panama, and a later specimen came from Cartago Province in Costa Rica, at elevations of 1,290 to 1,500 meters above sea level; every specimen was collected in premontane forest near coffee plantations. The IUCN evaluated it in 2017 as Data Deficient because the extent of its range and the size of its population are unknown.
