Análisis filogenético del género Mimon Gray, 1847 (Mammalia, Chiroptera, Phyllostomidae) con la descripción de un nuevo género

Abstract

Introduction:Mimon is currently considered a monophyletic genus that comprises two subgenera: Mimon (represented by M. bennettii and M. cozumelae), and the taxon formerly named "Anthorhina" (represented by M. crenulatum and M. koepckeae). However, recent molecular phylogenies show Mimon as a polyphyletic genus within Phyllostomidae. Methods:Herein, we present a phylogenetic approach based on morphology, which includes all species of the genus Mimon, with emphasis on geographical populations of M. crenulatum. Our data matrix was built with our own examination of M. bennetti (n = 5), M. cozumelae (n = 31), M. crenulatum (n = 181), and M. koepckeae (n = 3) for 91 morphological characters including external, skull-dental and postcraneal traits. The species Lophostoma occidentalis, Trachops cirrhosus, Tonatia saurophila, Phyllostomus discolor, Phylloderma stenops, and Micronycteris megalotis were selected as outgroups. The tree was rooted on M. megalotis. An exhaustive search with 135 unordered characters was performed to find the most parsimonious trees. Results:A single well-supported tree of 306 steps was obtained. Bootstrap and Jacknife with 10,000 resampling were used as support estimators. The most parsimonious tree confirms Mimon is a polyphyletic genus, where the subgenus Mimon and the taxon formerly named "Anthorhina" are strongly supported but unrelated monophyletic groups. Discussion and conclusions:In order to solve this taxonomic problem, we recommend the taxon formerly named "Anthorhina" be raised at genus level, but with a new name because "Anthorhina" is a synonym of Tonatia. Finally, we provide an emended diagnosis of Mimon s.s. and the description of a new genus, based on morphological characters used for the phylogeny.Key words: Gardnerycteris nov. gen., morphological, maximun parsimony.Mimon es considerado actualmente un género monofilético conformado por dos subgéneros: Mimon (representado por M. bennettii y M. cozumelae), y el taxón anteriormente llamado "Anthorhina" (representado por M. crenulatum y M. koepckeae). Sin embargo, los recientes resultados de estudios filogenéticos moleculares indican que Mimon es un género parafilético dentro de Phyllostomidae. En el presente estudio se realizó una revisión de et al. (2000). Se obtuvo un único árbol más parsimonioso bien soportado de 306 pasos. El soporte de las ramas fue pesado con Bremer y el remuestreo por Bootstrap y Jacknife con 10,000 réplicas. El árbol más parsimonioso confirma que Mimon es polifilético donde los subgéneros y el taxón anteriormente llamado "Anthorhina" están fuertemente respaldados en nodos no relacionados. Con la finalidad de resolver el surgente problema taxonómico, recomendamos elevar al taxón anteriormente llamado "Anthorhina" a género.Dado que "Anthorhina" es sinónimo de Tonatia, se propone un nuevo nombre. Finalmente, brindamos las diagnosis corregidas de Mimon s.s. y del nuevo género Gardnerycteris, basadas en los caracteres usados en el análisis filogenético.

Roosting ecology of Stenodermatinae bats (Phyllostomidae): evolution of foliage roosting and correlated phenotypes

“…Taxonomy of genera and species follows Gardner (), except for the following cases: (1) we use the recently described genera Gardnerycteris and Hsunycteris (Hurtado & Pacheco , Parlos et al. ); (2) we treat Platyrrhinus incarum as a species, not as subspecies of Platyrrhinus helleri , and include the newly described species Platyrrhinus fusciventris following Velazco et al.…”

Roosting Ecology of Amazonian Bats: Evidence for Guild Structure in Hyperdiverse Mammalian Communities

“…Several widely used epithets are no longer recognized as valid, some widespread "species" are now recognized as species complexes, and a few genera as formerly understood (e.g., Lonchophylla, Tonatia, Mimon) are now known to be paraphyletic. Taxonomic usage in this report follows Gardner (2008), who provided full bibliographic information (authors, dates, synonymies) for all binomina used herein, with the following exceptions: (1) we use Gardnerycteris as the appropriate genus for the bat formerly known as Mimon crenulatum after Hurtado and Pacheco (2014); (2) we use Hsunycteris for the species formerly known as Lonchophylla thomasi following Parlos et al (2014), who also described the species H. pattoni; (3) our use of binomina in Platyrrhinus follows Velazco et al (2010), who recognized P. incarum as a distinct species from P. helleri and described additional new species; and (4) we use Micronycteris homezorum as the appropriate spelling for M. "homezi" following Solari (2008). Additionally, we recognize that the bats currently known as Sturnira lilium represent a species complex that includes a distinct but still unnamed endemic Amazonian taxon (Velazco and Patterson, 2013).…”

Do riparian forest strips in modified forest landscapes aid in conserving bat diversity?

“…cinerea , Chiroderma trinitatum , Lionycteris spurelli , Micronycteris hirsuta , M. minuta , Platyrrhinus incarum , Phyllostomus discolor ) with none of them restricted to the cleared matrix. In contrast, seven species were missing at RS sites, including Mimon crenulatum (recently revised to Gardenycteris crenulatum , Hurtado & Pacheco, ), Vampyriscus bidens, and Vampyressa thyone in addition to the unique species from F and FS treatment. Considering those species captured more than once, only two species were restricted to a particular habitat; Lophostoma carrikeri and Sturnira cf.…”
