Sturnira koopmanhilli

Sturnira koopmanhilli is a species of leaf-nosed bat found in South America. It was described as a new species in 2006 from a holotype collected in 1991 in the Cotacachi Cayapas Ecological Reserve, a nature reserve in Ecuador. Its species name honours the American zoologist Karl Koopman and the British mammalogist John Edwards Hill. The species has been documented in Ecuador and Colombia at altitudes from 300 to 2,000 metres above sea level. Males have a forearm length of 49.2 to 52.4 millimetres and females 48.1 to 52.2 millimetres, and the species has a dental formula giving 32 teeth in total. As of 2016 the IUCN evaluated it as Data Deficient because basic details of its biology and ecology are not yet known, and deforestation of the Tumbes-Choco-Magdalena region may affect it.
