Chinese rufous horseshoe bat

Rhinolophus sinicus, the Chinese rufous horseshoe bat (Rhinolophidae), is a medium-sized insectivorous bat with a body length of 4.1–5.3 cm, a forearm of 4.3–5.6 cm, a weight of 9–14 g and a diploid chromosome number of 36. The broad noseleaf emits constant-frequency ultrasound for echolocation in dense vegetation. It occurs in southern and south-western China, northern India, Nepal, Bhutan and northern Vietnam, roosting in humid karst caves and abandoned tunnels, often with other bat species. IUCN assessed it as Least Concern in 2019. Since 2005, SARS-related coronaviruses have been detected in the species.
