A new polytypic species of yellow-shouldered bats, genus Sturnira (Mammalia: Chiroptera: Phyllostomidae), from the Andean and coastal mountain systems of Venezuela and Colombia

Sturnira is the most speciose genus of New World leaf-nosed bats (Phyllostomidae). We name Sturnira adrianae, new species. This taxon is born polytypic, divided into a larger subspecies (S. a. adrianae) widespread in the mountains of northern and western Venezuela, and northern Colombia, and a smaller subspecies (S. a. caripana) endemic to the mountains of northeastern Venezuela. The new species inhabits evergreen, deciduous, and cloud forests at mainly medium (1000-2000 m) elevations. It has long been confused with S. ludovici, but it is more closely related to S. oporaphilum. It can be distinguished from other species of Sturnira by genetic data, and based on discrete and continuously varying characters. Within the genus, the new species belongs to a clade that also includes S. oporaphilum, S. ludovici, S. hondurensis, and S. burtonlimi. The larger new subspecies is the largest member of this clade. The two new subspecies are the most sexually dimorphic members of this clade. The smaller new subspecies is restricted to small mountain systems undergoing severe deforestation processes, therefore can be assigned to the Vulnerable (VU) conservation category of the International Union for Conservation of Nature (IUCN).

First record of the pale-faced bat Phylloderma stenops Peters 1865 (Chiroptera: Phyllostomidae) in the province of Guayas, Southwest Ecuador

We report the first record of Phylloderma stenops in the province of Guayas, Ecuador. The specimen was captured in a heavily disturbed area, surrounded by small remnants of semi-deciduous lowland forests. We also present a predictive distribution map, constructed with the new and existing information for P. stenops in Ecuador and other countries in South America, showing that this species may occur in other areas where it has not yet been observed.

Genus Glyphonycteris Thomas, 1896 (Mammalia: Chiroptera) in Ecuador: first confirmed record of G. sylvestris Thomas, 1896 and a geographical review to G. daviesi (Hill, 1965) [with erratum]

Herein we present a geographical review to the genus Glyphonycteris in Ecuador. We confirm the first record for G. sylvestris for the country, which extends its range about 680 km southwest of the nearest previously known record. This first record belongs to an individual captured in Sangay National Park, Morona Santiago province, eastern slopes of the Andes. We also review the records of G. daviesi deposited in scientific collections and mentioned in literature, report a new record from west of the Andes, and present a distribution map.

Mammalia, Chiroptera, Thyropteridae, Thyroptera tricolor Spix, 1823: distribution extension in Ecuador

In Ecuador, Thyroptera tricolor is distributed on the northern coastal region, in Amazonia, and in the foothills of the Andes between 50 to 1,800 m of altitude. We reported a capture of a non-breeding female at El Descanso, Los Rios Province, in the central coastal region of Ecuador. With this record, we have extended the geographical distribution of T. tricolor in Ecuador 55 km further south. Using the available data for Ecuador, a predictive distribution model was generated using a Maximum Entropy approach.

Mammalia, Chiroptera, Phyllostomidae, Lampronycteris brachyotis (Dobson, 1879): first confirmed record for Ecuador

Herein we report the first record for Lampronycteris brachyotis in Ecuador, which extends its range about 570 km west of the nearest previously known published record in Loreto, Peru. We captured an adult male on 31 October 2008 in Tarangaro, near the Manderoyacu River, Pastaza province. This locality is placed in a flat, periodically flooded river valley, with small estuaries. The forest is well preserved with high canopy trees. There also are small agricultural patches in the zone.

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

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.

Lophostoma carrikeri (Allen, 1910) (Chiroptera: Phyllostomidae): First confirmed records in Ecuador

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.

Mammalia, Chiroptera, Phyllostomidae, Lonchophylla hesperia G. M. Allen, 1908: second record of the Western Nectar Bat in Ecuador after 70 years

Herein we report the second record for Lonchophylla hesperia in Ecuador, and the first one since 1939. We captured an adult male in a mountainous dry valley at Comunidad San Jacinto, Catamayo Valley, Loja Province, southwestern Ecuador. The dominant landscape consists of agricultural lands, mainly of corn fields and pastures; while the natural forest is restricted to small patches. A description of the species’ shelter and a predictive distribution model in Peru and Ecuador are presented, indicating the areas between the two countries were the habitat is climatically suitable for its presence.

Mammalia, Chiroptera, Emballonuridae, Peropteryx leucoptera Peters, 1867 and Peropteryx pallidoptera Lim, Engstrom, Reid, Simmons, Voss and Fleck, 2010: Distributional range extensions in Ecuador

We reevaluate vouchered records of Peropteryx leucoptera in Ecuador with regard to the morphologically similar and newly described species, P. pallidoptera . The western-most distributional occurrence of P. pallidoptera is documented. Additionally, we describe a new record of P. leucoptera collected at Palma Roja, Cuyabeno Faunistic Reserve in Sucumbios Province, Ecuador that represents the first record for this species in Sucumbios Province and the northern-most distributional occurrence for Ecuador.
