Abstract
Herein we confirm the occurrence of Lophostoma carrikeri in Ecuador. One adult female was collected in Orellana province on 17 September 2012 at Boanamo, Waorani Ethnic Reserve, and another on 5 May 2013 at Yasuni Research Station, Yasuni National Park. These records extend the distributional range of the species about 570 km northwest of the nearest previously known record in Jenaro Herrera, Loreto, Peru. Both Ecuadorian localities are characterized by well-conserved primary Terra Firme rainforest. Morphological characters of the specimens presented here broaden the known intraspecific variation in this taxon, including uniformly dark ears without white margins, undeveloped sagittal crests, and smaller forearm size than previously reported. In addition, information on ectoparasites for this species in Ecuador is provided.
Highlights
Rex et al (2008) reported the presence of a fifth species of Lophostoma for Ecuador, L. carrikeri (Allen, 1910), from the capture of three individuals: A pregnant female captured at the Tiputini Biodiversity Station (TBS, 00°38.21′ S, 76°8.92′ W, 190–270 m), Orellana province in eastern Ecuador, and a pregnant female and an adult male captured at Bombuscaro River in the Podocarpus National Park (BOM, 04°1′ S, 79°1′ W, 900–1,200 m), Zamora Chinchipe province, on the eastern slope of the Andean mountains of southern Ecuador
As mentioned by the authors, not all species reported in their study were collected and preserved as museum voucher specimens: “species that were difficult to identify or were considered new for each site” were reportedly deposited in the American Museum of Natural History (AMNH), New York, USA (Rex et al 2008)
Individuals of the captured Lophostoma species were never formally accessioned at AMNH
Summary
Rex et al (2008) reported the presence of a fifth species of Lophostoma for Ecuador, L. carrikeri (Allen, 1910), from the capture of three individuals: A pregnant female captured at the Tiputini Biodiversity Station (TBS, 00°38.21′ S, 76°8.92′ W, 190–270 m), Orellana province in eastern Ecuador, and a pregnant female and an adult male captured at Bombuscaro River in the Podocarpus National Park (BOM, 04°1′ S, 79°1′ W, 900–1,200 m), Zamora Chinchipe province, on the eastern slope of the Andean mountains of southern Ecuador. Round-eared bats, genus Lophostoma d’Orbigny, 1836, include eight species (Velazco and Gardner 2012), four of which have been reported to occur in Ecuador: Lophostoma brasiliense Peters, 1867 is widely distributed in eastern lowland rainforest, between 200 and 700 m (Williams and Genoways 2008; Tirira 2012), and recently has been recorded from several localities in the western lowlands, between 50 and 500 m (Carrera et al 2010; Velazco and Cadenillas 2011; Regalado and Albuja, 2012); L. silvicolum d’Orbigny, 1836, in the eastern lowlands extending into the Andean foothills, between 200 and 1,250 m (Davis and Carter 1978; Medellín and Arita 1989; Tirira 2012); L. occidentalis (Davis & Carter, 1978) known from the Pacific coast between 5 and 1,300 m (Velazco and Cadenillas 2011; Tirira 2012); and L. yasuni Fonseca & Pinto, 2004, known only from the type locality at Yasuni Research Station (YRS), Orellana province, in the eastern lowlands (250 m).
