First records of Myotis nigricans (Schinz, 1821) (Chiroptera, Vespertilionidae) and two new localities for three bat species in Santa Fe province, Argentina

Abstract

We present the first records of Myotis nigricans (Schinz, 1821) for Santa Fe province, Argentina. Four specimens were collected in the following localities: Esperanza (Las Colonias department), Laguna Paiva (La Capital department), and Rosario (Rosario department). These records extend the distribution area of M. nigricans 380 km to the south and increase the number of bat species in Santa Fe to 23. Additionally, Esperanza and Rafaela are added as new localities for Eumops glaucinus (Wagner, 1843), Molossops temminckii (Burmeister, 1854), and Lasiurus blossevillii (Lesson & Garnot, 1826).

New records of bats (Mammalia: Chiroptera) from Entre Ríos and Santa Fe provinces, Argentina

“…Paraná, centro-oeste de la misma, donde previamente era conocida para los departamentos La Paz, Tala y Colón (Oviedo, 2009;Massa et al, 2014). Para la provincia de Santa Fe existen tres registros previos de la especie en los departamentos Las Colonias, La Capital y General Obligado (Yepes, 1944;Barquez et al, 1999;Montani et al, 2018 (Barquez et al, 1999;Udrizar Sauthier et al, 2008;de Souza & Pavé, 2009;Oviedo, 2009;Massa et al, 2014;Oviedo et al, 2016); los ejemplares aquí registrados permiten incorporar nuevas localidades en los departamentos Paraná y Colón. Para la provincia de Santa Fe los únicos registros conocidos de la especie son para el Dpto.…”

“…Si bien en los últimos años se han incorporado varias especies de quirópteros a la mastofauna de Entre Ríos y Santa Fe (Massa et al, 2014;Lutz et al, 2016;Pavé et al, 2017;Díaz et al, 2018;Montani et al, 2018) todavía faltan estudios sistemáticos principalmente en el norte de ambas provincias, en las ecorregiones Espinal y Chaco Húmedo, donde existen departamentos provinciales sin registros de quirópteros. En estas regiones se requiere la confirmación de especies presentes en provincias cercanas para llenar vacíos de información en su distribución geográfica, en especial del género Myotis, como M. albescens, M. dinellii, M. levis, M. nigricans y M. ruber y de especies frugívoras y nectarívoras de la familia Phyllostomidae, como Sturnira lilium, Carollia perspicillata y Platyrrhinus lineatus (Barquez & Díaz, 2020).…”

Heterogeneous taxonomic resolution of cytochrome b gene identification of bats from Argentina: Implications for field studies

“…This study aims to discuss the extent of the use of the mitochondrial cytochrome b gene for species identification, comparing external morphology identification with a molecular phylogenetic classification based on this marker, and current bat systematics. We used as a case study a set of samples collected in a Rabies virus eco-epidemiological survey involving five localities in the province of Santa Fe (Argentina), where 24 species from 3 families (Phyllostomidae, Molossidae, and Vespertilionidae) and 12 genera have been reported [14,15,30,31]. We further obtained sequences from museum vouchers to test the accuracy of Cytb-based phylogenies in taxonomic identification of bats occurring in the Pampean/Chacoan regions of Argentina.…”

First record of Promops centralis Thomas, 1915 (Chiroptera, Molossidae) in Santa Fe province, Argentina

“…Santa Fe, a province that extends over a plain area of more than 132,000 km 2 , is located in the central-eastern part of Argentina, and includes five ecoregions: Humid Chaco, Dry Chaco, Espinal, Pampa, and Delta and Islands of the Paraná (Burkart et al 1999;Biasatti et al 2016). Until now, 23 bat species have been cited for the province (Cabrera 1938;Yepes 1944;Crespo 1974;Vaccaro 1992;Barquez 2006;Pautasso 2008;Pautasso and Arnaudo 2009;Pavé et al 2017;Montani et al 2018), representing one-third of the bat diversity recorded for Argentina (Barquez et al 2020).…”
