“…Previous craniometric analyses have highlighted the distinctiveness of both Artibeus anthonyi and A . (subgenus Koopmania ) concolor (Balseiro et al., ; Marchán‐Rivadeneira et al., ), but our analyses are the first to suggest both these lineages are nested within the subgenus Artibeus . In both undated and relaxed clock analyses A. concolor and A. anthonyi form a clade with Artibeus fimbriatus , resulting in the paraphyly of the subgenus Artibeus (Figure , Figure S1).…”

Aim Previous phylogenies of extant short‐faced bats (Chiroptera: Stenodermatina) supported either two colonization events from the mainland to the Antilles, or reverse colonization, but lacked both fossil data and statistical modelling of biogeography. Recent multi‐locus phylogenies of noctilionoid bats and likelihood modelling of ancestral ranges support a continental origin for the clade. We include all known extinct and extant stenodermatina species and apply statistical modelling to test competing biogeographical hypotheses. Location The Neotropics, including the Antilles. Methods We combined mitochondrial and nuclear sequences with 302 new morphological characters to infer phylogenies. Bayesian tip‐dating analyses applied codon models to protein‐coding genes, with relaxed molecular clocks fitting a compound Poisson process. The combined maximum clade credibility tree was used in comparisons of alternative biogeographical models. Results The new phylogenies support the fossil Cubanycteris silvai as sister to all extant species of short‐faced bats. Among Artibeus (the sister group to short‐faced bats), the Antillean fossil A. anthonyi has distinctive characters and is nested within the subgenus Artibeus. The common ancestor of all short‐faced bats is inferred to be Antillean, as a mainland origin is unlikely. Founder‐event speciation is the most probable process explaining the distribution of these highly divergent fossil lineages. Main conclusions Dated, character‐based phylogenies of fossil species are indispensable for biogeographical inference: without fossils, biogeographical analyses find a mainland origin for short‐faced bats. The rate of founder speciation in this clade is twice as high as the estimate from noctilionoids in general, highlighting the role of founder events in the diversification of island taxa. Although rare, reverse colonization contributes key species to continental communities. Short‐faced bats, including Cubanycteris, share biomechanical adaptations for a strong bite conferring access to harder figs. We hypothesize these adaptations and characters related to roosting ecology enabled ancestral lineages to successfully establish and diversify on the mainland.

“…The taxonomic classification proposed by Hoofer et al (2008) recognized Artibeus as a distinct subgenus from Dermanura . Recently, Marchán-Rivadeneira et al (2010) described the genus Artibeus as constituted by 11 large-body size species including Artibeus concolor as the basal taxon. Its distributional range is restricted to the Neotropical region.…”

The genus Artibeus represents a highly diverse group of bats from the Neotropical region, with four large species occurring in Brazil. In this paper, a comparative cytogenetic study was carried out on the species Artibeus obscurus Schinz, 1821, Artibeus fimbriatus Gray, 1838, Artibeus lituratus Olfers, 1818 and Artibeus planirostris Spix, 1823 that live sympatrically in the northeast of Brazil, through C-banding, silver staining and DNA-specific fluorochromes (CMA3 and DAPI). All the species had karyotypes with 2n=30,XX and 2n=31,XY1Y2, and FN=56. C-banding showed constitutive heterochromatin (CH) blocks in the pericentromeric regions of all the chromosomes and small CH blocks at the terminal region of pairs 5, 6, and 7 for all species. Notably, our C-banding data revealed species-specific autosomic CH blocks for each taxon, as well as different heterochromatic constitution of Y2 chromosomes of Artibeus planirostris. Ag-NORs were observed in the short arms of chromosomes 5, 6 and 7 in all species. The sequential staining AgNO3/CMA3/DA/DAPI indicated a positive association of CH with Ag-NORs and positive CMA3 signals, thus reflecting GC-richness in these regions in Artibeus obscurus and Artibeus fimbriatus. In this work it was possible to identify interespecific divergences in the Brazilian large Artibeus species using C-banding it was possible provided a suitable tool in the cytotaxonomic differentiation of this genus.

“…probably some skull measurements might be more useful to discriminate A. inopinatus from A. jamaicensis paulus). Differentiation based on cranium measurements was already analyzed in Artibeus (Lim 1997;Marchán-Rivadeneira et al 2010), but were not specifically discussed considering A. inopinatus, and characteristics from the skulls can only be verified in dead specimens. Additionally, the results presented here indicate that the main characteristics for the external identification of A. inopinatus in the field in comparison with A. jamaicensis and A. lituratus are the forearm length, third metacarpal length, the length of the second phalanx of digit III, and body length.…”

“…The Neotropical genus Artibeus (sensu stricto) within the Stenodermatinae subfamily comprises 12 recognized species and is considered as a recognized representative of the assemblage of the Neotropical chiropteran fauna (Lim 1997;Larsen et al 2010). Artibeus (sensu lato), supported by morphological analysis, was traditionally divided into two taxa according to body size, Artibeus (large species) and Dermanura (small species) (Marchán-Rivadeneira et al 2010), but Owen (1991) described Koopmania from a previously known species as A. concolor. Thus, many authors have systematic and taxonomic criteria to support the division of the genus into three genera (Larsen et al 2007;Hoofer et al 2008;Redondo et al 2008;Larsen et al 2010).…”

Rare or misidentified? On the external identification of the neglected Artibeus inopinatus Davis & Carter, 1964 (Chiroptera, Phyllostomidae) in Honduras

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.
