“…Even among birds, a group which comprises more readily phenotypically discernible species, there may be twice as many evolutionarily distinct species than re ected by traditional morphometrics (Barrowclough et al, 2016). Globally, DNA barcoding studies have helped re ne species boundaries across both bats (Benítez et al, 2021;Clare et al, 2007Clare et al, , 2011; Kruskop et al, 2012) and birds (Chaves et al, 2015;Kerr et al, 2009a;Kerr et al, 2009b;Saitoh et al, 2015), although these studies have been skewed predominantly towards the eastern Palaearctic, Nearctic, and especially the Neotropics. But despite several studies demonstrating the e cacy of this molecular tool, few have employed it on a broad geographic scale.…”

Cryptic species present a challenge for conservation, as undetected diversity may be lost. DNA barcoding of the mitochondrial cytochrome c oxidase subunit I (COI) has become a useful heuristic tool for delimiting species boundaries and detecting cryptic speciation across different animal taxa. Despite concerted efforts to genetically barcode bats and birds, comprehensive assessments have yet to be undertaken across the Afrotropics. We retrieved available DNA barcodes of bat and bird species naturally breeding within the Afrotropics. Using Bayesian phylogenetic modelling, we assessed DNA barcode performance at species identification, and to detect instances of non-monophyly (indicating potential cryptic speciation). Available DNA barcodes represent only 42.3 % and 23.6 % of the relevant bat and bird species diversity, respectively, with only 18.7 % of bat species and 7.2 % of bird species having geographic coverage. DNA barcodes afforded greater taxonomic resolution of Afrotropical bird species than of bats (96.8 % vs 84.0 %), with the bats reporting a higher species non-monophyly (25.5 % vs 4.8 %). Twenty-one bat species and fifteen bird species exhibited well-supported phylogenetic complexity. Additionally, deep intraspecific divergences (>2.0 %) were observed in one bat species and fifteen bird species. These instances of non-monophyly and deep intraspecific divergences may represent cryptic speciation within these volant taxa, suggesting greater hidden diversity of more sedentary African fauna. They also highlight the importance of areas such as the Congo-Guinean lowland forests to endemic vertebrate diversity. The current taxonomic status of birds is better supported by this molecular evidence than that of bats.

“…Igualmente, es necesario revisar el material asignado a S. erythromus que se considera una especie de alta montaña, sobre los 1500 m(Mantilla-Meluk et al, 2009;Solari et al, 2013). Así mismo, se incluye a Uroderma magnirostrum, reportado para el departamento por Cabrera-Durán (2011), ya que, aunque no cuenta con especímenes de referencia, se asume su presencia por los hallazgos en áreas próximas a Sucre(Benítez et al, 2021). Pteronotus fuscus corresponde a cambios en la taxonomía de la especie considerada anteriormente dentro del complejo P. parnelli(Pavan & Marroig 2017;Chacón-Pacheco et al, 2018).El hallazgo del murciélago Ametrida centurio en el departamento de Sucre corresponde al primer registro de esta especie para el país, después de que fuera excluida de la última actualización de los mamíferos de Colombia debido a la falta de evidencia y confusiones con la especie Sphaeronycteris toxophyllum.…”

Se presenta la lista de los mamíferos del departamento de Sucre, basada en la revisión de especímenes depositados en colecciones biológicas, registros novedosos y disponibles en la literatura científica y observaciones de los autores. Encontramos 143 especies, que representan el 26.3 % de los mamíferos registrados en Colombia. Cinco especies son endémicas de Colombia: Cebus versicolor, Pattonomys semivillosus, Proechimys chrysaeolus, Saguinus oedipus y Sylvilagus sanctaemartae; cinco han sido categorizadas como Datos Insuficientes, y 13 y 17 se encuentran en alguna categoría de amenaza a nivel nacional y global, respectivamente. Se registra por primera vez para Colombia el murciélago Ametrida centurio, con base en una fotografía tomada en el municipio de Santiago de Tolú. Registramos mayor riqueza de especies al norte del departamento, en las subregiones Golfo Morrosquillo y Montes de María, probablemente producto del mayor esfuerzo de recolección. Es necesario incrementar los esfuerzos locales, debido a la insuficiente o nula exploración en algunas áreas del departamento.

Cryptic species present a challenge for conservation, as species diversity may remain undetected. In zoological research, DNA barcoding of the mitochondrial cytochrome c oxidase subunit I (COI) has become a useful heuristic tool for aiding species resolution and informing species discovery. Despite concerted efforts to genetically barcode bats and birds, comprehensive assessments have yet to be undertaken across the Afrotropics. We retrieved available DNA barcodes of native breeding Afrotropical bat and bird species. Using Bayesian phylogenetic modelling, we assessed DNA barcode performance at species identification, and sought to detect notable intraspecific clade partitioning hinting at cryptic speciation. Available DNA barcodes represent only 42.3% and 23.6% of the relevant bat and bird species diversity, respectively, with only 18.7% of bat species and 7.2% of bird species having geographically spread records. DNA barcodes afforded greater taxonomic resolution of Afrotropical bird species than of bats (96.8% vs. 84.0%), with bats having a higher proportion of species non-monophyly (25.5% vs. 4.8%). Well-supported (≥ 95% posterior probability) clade partitioning was inferable from twenty-one bat species and fifteen bird species, and a further single under-sampled bat species and fifteen such bird species showed deep (> 2.0%) intraspecific divergences. These phylogenetic signatures allude to cryptic speciation within these volant taxa, and serve to prompt more comprehensive assessments of Afrotropical fauna. These findings also indirectly affirm the importance of paleoclimatic refugia to endemic vertebrate diversity. The current taxonomic status of birds is better supported by this molecular evidence than that of bats.
