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.
Understanding biodiversity patterns as well as drivers of population
declines, and range losses provides crucial baselines for monitoring and
conservation. However, the information needed to evaluate such trends
remains unstandardised and sparsely available for many taxonomic groups
and habitats, including the cave-dwelling bats and cave ecosystems.
Here, we present the DarkCideS 1.0, a global database of bat
caves and bat species based on curated data from the literature,
personal collections, and existing datasets. The database contains
information for geographical distribution, ecological status, species
traits, and parasites and hyperparasites for 679 bat species known to
occur in caves or use caves in their life-histories. The database
contains 6746 georeferenced occurrences for 402 cave-dwelling bat
species from 2002 cave sites in 46 countries and 12 terrestrial biomes.
The database has been developed to be a collaborative, open-access, and
user-friendly platform, allowing continuous data-sharing among the
community of bat researchers and conservation biologists. The database
has a range of potential applications in bat research and enables
comparative monitoring and prioritisation for conservation.
In Central America, Vampyressa is represented by two species, Vampyressa elisabethae and V. thyone. The latter is the only representative of the genus in Honduras and the most recent record was in 2007. Six surveys were carried out in the Departments of Cortés, Atlántida and Gracias a Dios. Only seven individuals of V. thyone were recorded between March 2016 and September 2017. The low abundance of V. thyone supports the fact that it is an uncommon species in the country; however, these records update the distribution in northern Honduras. We recommend systematic bat assessments on the three protected areas in which we recorded V. thyone for a better comprehension of the local populations on this species in the country.
For years, the identification of Artibeus species has been controversial due to the overlap of morphometric characteristics between species. From February 2015 to September 2019, we sampled 25 sites in 10 departments of Honduras, and captured 81 Artibeus individuals using mist-nets. We determined the morphometric measurements that may be helpful in the identification of adult individuals of the Honduran Fruit-eating Bat, Artibeus inopinatus, in the field. We analyzed 648 morphometric measurements using a linear discriminant analysis, and determined that the forearm length, third metacarpal length, the length of the second phalanx of digit III, and body length are the main characteristics for the external identification of A. inopinatus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
