A New Species of Nectar-Feeding Bat of the GenusHsunycteris(Phyllostomidae: Lonchophyllinae) from Northeastern Peru

Abstract

A new species of the nectarivorous bat genus Hsunycteris is described from lowland Amazonian forest in northeastern Peru. The new species, H. dashe, can be distinguished from other congeners by its larger size; V-shaped array of dermal chin papillae separated by a wide basal cleft; metacarpal V longer than metacarpal IV; broad rostrum; lateral margin of infraorbital foramen not projecting beyond rostral outline in dorsal view; well-developed sphenoidal crest; large outer upper incisors; weakly developed lingual cusp on P5; and well-developed, labially oriented M1 parastyle. A phylogenetic analysis of cytochrome-b sequence data indicates that H. dashe is sister to a clade that includes all other species of the genus including H. cadenai, H pattoni, and a paraphyletic H. thomasi. We provide a key based on craniodental and external characters of all four known species of Hsunycteris.

Diversidad y conservación de los murciélagos de Loreto, Perú

“…De estas 39 especies, 32 se han registrado en los departamentos contiguos de Ucayali, San Martín y Amazonas (Pacheco & Patterson 1992, Solari et al 2001, Pacheco 2003, Handley & Gardner 2008, Davis & Gardner 2008, Quintana et al 2009, Rengifo et al 2011, Tavares et al 2014 (Pacheco et al 2009), Carollia sp. sensu (Ruelas & López 2018), Platyrrhinus fusciventris (Velazco et al 2021), Peropteryx pallidoptera (Lim et al 2010), Eumops maurus, E. delticus ), Molossus alvarezi (González-Ruiz et al 2011, Artibeus bogotensis (Calderón & Pacheco 2012), Thyroptera wynneae ) y Hsunycteris dashe (Velazco et al 2017).…”

“…Endemismo, Conservación y Rareza de especies. -La reciente descripción de la especie endémica Hsunycteris dashe (Velazco et al 2017) y el reconocimiento de Tonatia maresi y Glossophaga bakeri como especies válidas (Basantes et al 2020, Velazco et al 2021) hacen necesaria la evaluación de su categoría de Amenaza según las normas de la IUCN.…”

“…Para la nomenclatura y arreglo taxonómico se siguió a Gardner (2008) y a Pacheco et al (2009), agregándose cambios taxonómicos recientes. Para murciélagos, estos cambios incluyen a Velazco y Simmons (2011), Parlos et al (2014), Hurtado y Pacheco (2014), Baker et al (2016), Velazco y Patterson (2014), Velazco et al (2017), Basantes et al (2020) y Velazco et al (2021).…”

Community Ecology and Phylogeography of Bats in the Guianan Savannas of Northern South America

“…A final pattern recovered is a split of Hsunycteris thomasi from the Llanos and Sipaliwini in two more broadly distributed clades including Venezuela west to Ecuador and Guyana east to Suriname. One of these lineages was considered an undescribed cryptic species, but the holotype from Ciudad Bolivar in Venezuela could not be unambiguously applied to identify which one corresponds to H. thomasi and which one requires a new taxonomic name [36]. However, our sample (ROM 107906) from Hato La Cerbatana, 20 km S of Guaniamo, Bolivar, Venezuela is in similar lowland Llanos habitat as the type locality, suggesting that the nominal name applies to the population from western Bolivar in Venezuela to Ecuador.…”

Short Communication: Second record of Eumops chiribaya (Chiroptera, Molossidae) in Peru

“…Peru is one of the five countries in the world with the greatest diversity of mammals, it being estimated that at least 566 species of mammals are distributed throughout Peru (Velazco 2013;Moras et al 2015, Pacheco et al 2009Medina et al 2016;Uturunco and Pacheco 2016;Sanchez and Pacheco 2016;Miranda et al 2017;Nascimento et al 2017;Hurtado and Pacheco 2017;Rocha et al 2017;Ruedas et al 2017;Suárez-Villota et al 2017;Velazco et al 2017;Do Prado and Percequillo 2018;Emmons and Fabre 2018;Voss et al 2018;Zeballos et al 2018). Rodents and bats represent two thirds of the total diversity (64%) for Peru (Pacheco et al 2009), due to evolutionary and adaptive exclusiveness that they have developed over time.…”
