A systematic revision of the bats (Chiroptera) of Honduras: an updated checklist with corroboration of historical specimens and new records

摘要

During the last century, survey efforts for mammals in Honduras have been few and most distributional and conservation assessments of bats have been based on historical records. Taxonomy of many records has changed. Moreover, a number of supposed Honduran occurrences are based on records from bordering countries without confirmation by a Honduran voucher. Therefore, the list of bats of Honduras lacks precision. Here, we update the number of species in the country, including taxonomic changes not reflected in recent works and new records based on museum specimens. The known number of species for Honduras is 113 with seven expected (Cormura brevirostris, Lampronycteris brachyotis, Mesophylla macconnelli, Molossus coibensis, M. pretiosus, Thyroptera discifera and Trinycteris nicefori), based on records in adjoining countries. We provide a new record for Honduras of Natalus lanatus. We confirm the presence of Cynomops greenhalli and Diaemus youngii and clarify the taxonomic status of Artibeus intermedius, Chiroderma gorgasi, Eumops ferox, Gardnerycteris keenani, Lasiurus frantzii, Myotis pilosatibialis, Molossus and Pteronotus species, and Tonatia bakeri. We recommend a reassessment of the conservation status of the bats of Honduras considering recent changes and that a number of species (e.g. Choeronycteris mexicana) have not been observed since their reports in historical records. This requires an update of the taxonomic identification keys for Honduras. The updated checklist below demonstrates the high biodiversity of Honduran bats but is also an example of how poorly many groups have been studied since they were first recorded in the country.
