| abstract | A new chigger mite Chiroptella baliensis n. sp. is described based on material from the diadem leaf-nosed bat Hipposideros diadema (Geoffroy) (Hipposideridae) in Bali Island (Lesser Sunda Islands, East Indonesia). With this newly described species, the genus Chiroptella includes 22 species, 13 in the subgenus Chiroptella Vercammen-Grandjean, 1960 (sensu stricto), and 9 in the subgenus Neosomia Vercammen-Grandjean, 1968. Species of Chiroptella are distributed throughout the Ethiopian region, the Oriental region, and the Australian region (and only marginally throughout the Palaearctic region) and are all associated with several families of bats. The paper also provides a key to all members of the genus and the new combinations for two species originally described as Chiroptella. |
