Myotis riparius (Chiroptera: Vespertilionidae)

Abstract

Abstract:Myotis riparius is a vespertilionid bat commonly called the riparian myotis. It is a medium-sized bat, with woolly fur; color of dorsal fur varies geographically from a reddish to blackish tinge. M. riparius is widely distributed in the Neotropics, occurring from Honduras southward into South America to Paraguay, northern Argentina, and Uruguay. It occurs in rainforests, savannas, and open habitats, at elevations from sea level to about 2,000 m. It is listed as "Least Concern" by the International Union for Conservation of Nature and Natural Resources.

First record of Myotis riparius Handley, 1960 (Chiroptera, Vespertilionidae) in Sergipe, northeastern Brazil

“…Myotis riparius occurs in varied environments, from open and forested habitats to altered areas, undergoing large habitat plasticity (Novaes et al 2017). The capture of the individual in the Reserva Particular do Patrimônio Natural do Caju, in an area associated with bodies of water, corroborates that reported by other studies, as this species is usually found in humid forested areas, forag-ing in environments close to water sources (e.g.…”

“…The specimens in Sergipe presented a forearm length at 34.19 mm (to CMUFS 291) and 35.90 mm (CMUFS 145) and is in agreement with reported measurements, for example, by Vicente et al (2005), Dias and Peracchi (2007) between the breadth across the canines and the postorbital constriction is over 1.0 (1.06), diagnostic features reported by López-González et al (2001) and Dias and Peracchi (2007). Other body and cranial measurements were similar (Table 1) to those reported by Simmons and Voss (1988), Lim et al (1999), López-González et al (2001, Dias and Peracchi (2007), and Novaes et al (2017).…”

“…The body and cranial measurements were obtained with a digital caliper with precision of 0.05 mm. The specimens were identified according to López-González et al 2001, Wilson (2008), and Novaes et al (2017).…”

Small Mammals of the Mayo River Basin in Northern Peru, with the Description of a New Species of Sturnira (Chiroptera: Phyllostomidae)

“…Myotis riparius Handley, 1960 Handley (1960), LaVal (1973, Simmons andVoss (1998), Brosset andCharles-Dominique (1990), Lopez-Gonzalez et al (2001), Moratelli et al (2013), andNovaes et al (2017). No subspecies are currently recognized in M. riparius (Novaes et al, 2017).…”

No subspecies are currently recognized in M. riparius (Novaes et al, 2017). Our Mayo River basin voucher speci¬ mens exhibit the diagnostic characteristics of the species: fur long and woolly; dorsal pelage unicol¬ ored; plagiopatagium attached to the foot at the level of the base of the toes; a fringe of hairs lack¬ ing along the trailing edge of uropatagium; sagittal and lambdoidal crests present; and occipital region flattened posteriorly (Novaes et al, 2017).…”
