Systematics of<i>Vampyressa melissa</i>Thomas, 1926 (Chiroptera: Phyllostomidae), with Descriptions of Two New Species of<i>Vampyressa</i>

The low representativeness of the dog‐faced bats (genus Cynomops Thomas, ) in collections has constrained the study of the diversity and the evolutionary relationships within this genus. Taxonomic revisions of some taxa, in particular the large‐sized Cynomops abrasus (Temminck, ), are crucial for understanding the phylogeny of Cynomops. A total of four subspecies of C. abrasus have been described to date, all widespread in South America: C. a. mastivus (Thomas, ), C. a. brachymeles (Peters, 1865), C. a. cerastes (Thomas, ) and C. a. abrasus (Temminck, ). Here, we evaluated the phylogenetic relationships within Cynomops, and the status of the four C. abrasus subspecies using complete sequences of two mitochondrial genes (Cyt b and COI) and 39 morphological characters. Maximum‐parsimony, maximum‐likelihood and Bayesian phylogenetic reconstructions recovered a novel hypothesis for Cynomops, supported the recognition of C. a. mastivus as a distinct species, separated from C. abrasus, and two hypotheses of lineages previously unrecognized for Cynomops. The use of mitochondrial genes combined with morphological characters revealed again to be a powerful tool to recover the phylogenetic relationships within Cynomops and demonstrated that the genus is more diverse than previously thought.

“…Of these characters, 160 were coded for four fossil taxa currently known for Stenodermatinae. These characters were based on, but not restricted to, those defined by Wetterer, Rockman, and Simmons (2000); Tavares (2008); Tavares and Mancina (2008); Tavares, Gardner, Ram ırez-Chaves, and Velazco (2014). The morphological matrix and character states were compiled using MacClade version 4.08 (Maddison & Maddison, 2003).…”

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.

“…In the genus Vampyressa there is a craniodental character, a small cusp in the lingual border of the longitudinal sulcus on posterior crown of upper canines (Tavares et al 2014), but in the V. thyone specimens examined in the MZFC-M the accessory cusps seem to be more developed in males than in females. Nevertheless, in the new specimen the accessory cusp is even more developed than in the other males.…”

“…The yellow-eared bats of the genus Vampyressa Wagner, 1843 consist of five different species, two of them recently described (Burgin et al 2018). These bats are considered primarily or exclusively frugivorous, though little is known of their feeding habitats or ecology (Tavares et al 2014). The distribution of this genus includes the Neotropical region, from Argentina to Mexico (Lim et al 2003).…”

Notes on Vampyressa thyone (Chiroptera: Phyllostomidae): distribution, genetics and hypopigmentation

The frugivorous bats of the genus Vampyressa include five neotropical species, and some of them are considered relatively rare and uncommonly encountered. The northernmost distribution of this genus is in Mexico where only one species, the monotypic Vampyressa thyone, is found. Here, we report the Northwesternmost record for this species, extending its distribution range to the state of Guerrero, Mexico. This record extends the limit of the species distribution by more than 153 km. We also compared this specimens with other V. thyone, and using mitochondrial cytochrome-b sequences we detected three geographic clades within the species. The new Mexican specimen represent the most divergent cytochrome-b sequence within V. thyone. We recommend a taxonomic revision to validate the taxonomic status of the three groups detected within V. thyone, particularly the differentiated Mexican clade. Additionally, we report a case of hypopigmentation in another V. thyone collected in a mature tropical rainforest in Chiapas, Mexico.
