A taxonomic revision of the Yasuni Round-eared bat, Lophostoma yasuni <br />(Chiroptera: Phyllostomidae)

Abstract

The Yasuni Round-eared bat, Lophostoma yasuni, was described in 2004 by morphological analysis of the holotype, the only specimen attributed to this taxon to date. A molecular analysis using cytochrome-b sequences and a new morpholo-gical analysis that includes the holotype of L. yasuni and two specimens of L. carrikeri from near the type locality of L. yasuni were carried out. The new molecular and morphological evidence places L. yasuni within the clade of L. carrikeri. We propose that L. yasuni should therefore be considered as a synonym of L. carrikeri. An emended diagnosis for L. carrikeri extending ranges of craniodental measurements for this species is presented.

Systematics and Taxonomy of Tonatia saurophila Koopman &amp; Williams, 1951 (Chiroptera, Phyllostomidae)

“…In addition to being dissimilar in size and morphology, they differ genetically at the 7.65% level, a percentage within the 3.3%-14.7% range of genetic distances known to separate sister species of mammals when the Cyt-b gene is considered (Baker and Bradley 2006). More recent works that resolve the taxonomic status of species in Phyllostomidae have shown similar genetic differences ranges to those of this study, such as between Sturnira burtonlimi and S. adrianae: 3.93% + 0.25, Sturnira hondurensis and S. ludovici: 5.74% + 0.46 (Molinari et al 2017), and, specifically in the subfamily Phyllostominae, Lophostoma silvicolum and L. evotis: 5.02% + 0.49; Lophostoma carrikeri and L. brasiliense: 12.78% + 0.97 (Camacho et al 2016); Gardnerycteris crenulatum and G. koepckeae: 11.2% + 1.0 (Hurtado and D'Elia 2018).…”

“…The remaining trees were used to obtain a consensus tree by 50% majority rule. To evaluate the monophyly and phylogenetic relationships of our Tonatia samples, several phyllostomines were selected as outgroup (Table 1), which have been used in previous works (Lee et al 2002;Velazco and Cadenillas 2011;Camacho et al 2016). The outgroup sequences were obtained from GenBank (www.ncbi.nlm.nih.gov/Genbank).…”

Sobre la distribución de tres especies de murciélagos filostómidos (Chiroptera), con registros adicionales para el Departamento de Gracias a Dios, Honduras

“…El género Chrotopterus es considerado monotípico, siendo C. auritus (Peters, 1856) la única conocida para el género, con una amplia distribución desde el sur de México hasta el norte de Argentina (Simmons, 2005;Álvarez-Yax et al, 2018). Por otro lado, el género Lophostoma se distribuye desde el sur de México hasta el centro de Paraguay y consiste en siete especies (Velazco & Cadenillas, 2011;Camacho et al, 2016), tres se han registrado en Honduras: L. evotis (Davis & Carter, 1978), L. brasiliense Peters, 1866, y L. silvicolum d'Orbigny, 1836 (Mora et al, 2018). Esta última es la de más amplia distribución dentro del género (Velazco & Cadenillas, 2011), y tiene una peculiar forma de hacer sus refugios en termiteros (Kalko et al, 2006).…”

RANGE EXTENSION OF CARRIKER’S ROUND-EARED BAT, Lophostoma carrikeri (ALLEN, 1910) (CHIROPTERA: PHYLLOSTOMIDAE) IN THE CERRADO AND CAATINGA

“…The genus Lophostoma d'Orbigny, 1836 currently comprises seven species of small to mediumsized neotropical leaf-nosed bats: L. silvicolum d'Orbigny, 1836; L. brasiliense Peters, 1866; L. carrikeri (Allen, 1910); L. occidentale (Davis & Carter, 1978); L. evotis (Davis & Carter, 1978); L. schulzi (Genoways & Williams, 1980); and L. kalkoae Velazco & Gardner, 2012 (Williams & Genoways 2008, Velazco & Cadenillas 2011, Velazco & Gardner 2012, Camacho et al 2016. Four of these species are currently recorded in Brazil: L. silvicolum, L. brasiliense, L. carrikeri and L. schulzi (Garbino et al 2020).…”

“…Lophostoma silvicolum and L. brasiliense are widespread in Central and South America while L. schulzi is restricted to northern South America (French Guiana, Guyana, Suriname and northern Brazil) (Barquez et al 2016, Sampaio et al 2016a, Sampaio et al 2016bSampaio et al 2016c). Lophostoma carrikeri has been reported in tropical rainforests, mesic and riparian forests, semideciduous savanna, and dry forests in southeastern Colombia, eastern Ecuador, southern Amazonas state in Venezuela, the Guianas, and north to central Brazil, adjacent to Peru and Bolivia (Sampaio et al 2016a, Sampaio et al 2016b, Camacho et al 2016. In Brazil, most records of L. carrikeri are within the Amazon biome, but in the last decade it was recorded for the first time in the Cerrado and reported in the Caatinga after 28 years since it was previously collected in this biome (Vizotto et al 1980, Gregorin et al 2008, Zortéa et al 2009, Gregorin et al 2011.…”
