The present catalogue documents all the chiropteran type specimens found in the collections of the Zoological Museum of the Humboldt-University, Museum für Naturkunde, Berlin (ZMB). Due to insufficient labeling at the time of receipt and description, many types have until now remained unrecognized, labelled with synonymous or incorrect names. From more than 13,000 specimens examined, we identified 540 types (86 holotypes, 249 syntypes, 22 lectotypes, 168 paratypes or paralectotypes, 5 of ambiguous status, 10 missing). These types belong to 218 described bat species, of which 116 are currently accepted (valid) species names. Lectotypes were designated for the original descriptions of Chilonycteris Boothi, Chiroderma villosum, Molossus ferox, Phyllorhina bicornis, Phyllostomus spiculatus, Rhinolophus capensis, Vespertilio Bocagii, Vespertilio Schreibersii and Vesperus cubanus.
