Abstract: Thirteen species of Neotropical bats of the genus Micronycteris are currently recognized and are allocated to four subgenera Leuconycteris, Micronycteris, Schizonycteris, and Xenonectes. Despite that, the presence of polyphyletic clades in molecular phylogenies suggests that its diversity is underestimated. Additionally, the incorrect identification of some genetic sequences, the incorrect assignation of available valid names, and restricted geographic sampling have biased the identification of independently evolutionary lineages within Micronycteris. In this study, several unknown genealogical lineages in the genus are identified and an updated phylogenetic hypothesis is proposed using mitochondrial and nuclear DNA fragments. The phylogenetic analyses congruently showed all individuals in four well-supported subgenera, but M. schmidtorum was revealed as the sister taxon of M. brosseti in the subgenus Leuconycteris. Twenty-seven different genealogical lineages were identified. These included eight confirmed species: M. brosseti, M. buriri, M. giovanniae, M. matses, M. schmidtorum, M. simmonsae, M. tresamici, and M. yatesi. Nineteen either allopatric or parapatric candidate species were also confirmed, two within the M. hirsuta complex, nine within the M. megalotis complex, seven within the M. minuta complex, and one corresponding to “M. sp.”. These results revealed an extensive undescribed diversity within each subgenus of Micronycteris. Nevertheless, the evolutionary processes associated with the specific radiations are poorly understood. This is just the beginning of the assessment of the taxonomy and systematics of Micronycteris, which requires additional integrative taxonomical approaches for its advance.

Cuba in Mexico: first record of Phyllops falcatus (Gray, 1839) (Chiroptera, Phyllostomidae) for Mexico and other new records of bats from Cozumel, Quintana Roo https://zookeys.pensoft.net/article/53185/ ZooKeys 973: 153-162

DOI: 10.3897/zookeys.973.53185

Authors: Noel Anselmo Rivas-Camo, Paulina Abigail Sabido-Villanueva, Carlos Ricardo Peralta-Muñoz, Rodrigo A. Medellin

Abstract: The first record of Phyllops falcatus (Gray, 1839) in Mexico is documented from the island of Cozumel, Quintana Roo. This species is present in the Antilles, distributed in all the Cuban archipelago, Cayman Islands, and Hispaniola. It is likely that a hurricane moved these bats from Cuba to Cozumel. The Cozumel record extends the distribution more than 200 km west. Two new records from Cozumel of the bats Lasiurus ega and Molossus alvarezi are also provided.

Cryptic diversity and range extension in the big-eyed bat genus Chiroderma (Chiroptera, Phyllostomidae) https://zookeys.pensoft.net/article/48786/ ZooKeys 918: 41-63

DOI: 10.3897/zookeys.918.48786

Authors: Burton K. Lim, Livia O. Loureiro, Guilherme S.T. Garbino

Abstract: Since the last systematic review of Chiroderma (big-eyed bats) more than two decades ago, we report on biodiversity surveys that expand the distribution and species diversity of this Neotropical genus. The Caribbean endemic species Chiroderma improvisum is documented for the first time from Nevis in the northern Lesser Antilles. A broader geographic sampling for a molecular analysis identifies a paraphyletic relationship in Chiroderma trinitatum with respect to Chiroderma doriae. Cis-Andean populations of C. trinitatum are most closely related to the morphologically distinctive and allopatrically distributed C. doriae in the Cerrado and Atlantic Forest of Brazil and Paraguay. The sister taxon to this grouping includes trans-Andean populations of C. trinitatum, which we recommend to elevate to species status as C. gorgasi. This is an example of a cryptic species because C. gorgasi was previously considered morphologically similar to C. trinitatum, but more detailed examination revealed that it lacks a posterolabial accessory cusp on the lower second premolar and has a narrower breadth of the braincase. We provide an amended description of Chiroderma gorgasi.

Systematics and Taxonomy of Tonatia saurophila Koopman & Williams, 1951 (Chiroptera, Phyllostomidae) https://zookeys.pensoft.net/article/46995/ ZooKeys 915: 59-86

DOI: 10.3897/zookeys.915.46995

Authors: Mateo Basantes, Nicolás Tinoco, Paúl M. Velazco, Melinda J. Hofmann, Miguel E. Rodríguez-Posada, M. Alejandra Camacho

Abstract: The Stripe-headed Round-eared bat, Tonatia saurophila, includes three subspecies: Tonatia saurophila saurophila (known only from subfossil records in Jamaica), Tonatia saurophila bakeri (distributed from southeastern Mexico to northern Colombia, Venezuela west and north of the Cordillera de Mérida, and northwestern Ecuador), and Tonatia saurophila maresi (distributed in Venezuela east and south of the Cordillera de Mérida, the Guianas, Trinidad and Tobago, northeastern Brazil, and along the upper Amazon basin in Colombia, Ecuador, Peru, and Bolivia). The last two subspecies are an attractive example to test predictions about the historical role of the Andes in mammalian diversification. Based on morphological descriptions, morphometric analyses, and phylogenetic reconstruction using the mitochondrial gene Cyt-b and the nuclear exon RAG2, this study evaluates the intraspecific relationships within Tonatia saurophila and the taxonomic status of the taxon. The three subspecies of T. saurophila are recognizable as full species: Tonatia bakeri, Tonatia maresi, and Tonatia saurophila. The latter is restricted to its type locality and possibly is extinct. Tonatia bakeri, in addition to being larger than T. maresi, is morphologically distinguishable by possessing an acute apex at the posterior edge of the skull, a well-developed clinoid process, and relatively robust mandibular condyles, and by lacking a diastema between the canine and the first lower premolar. The genetic distance between T. bakeri and T. maresi is 7.65%.

New records of Niceforo’s big-eared bat, Trinycteris nicefori (Sanborn, 1949) (Chiroptera, Phyllostomidae), from the state of Maranhão, Brazil https://zookeys.pensoft.net/article/26538/ ZooKeys 787: 127-134

DOI: 10.3897/zookeys.787.26538

Abstract: Niceforo’s big-eared bat, Trinycteris nicefori (Sanborn, 1949), is a monotypic species which has been recorded in a number of Brazilian states, but has a disjunct distribution in this country. This study presents the first record of T. nicefori in the Brazilian state of Maranhão. The specimens were collected in the municipalities of Godofredo Viana and Cândido Mendes, in fragments of the Amazon forest. One male (forearm: 38.00 mm, weight: 6 g) and one female (39.68 mm, 8 g) specimens were collected. The specimens presented chestnut-colored fur, and a chin with a pair of dermal pads arranged in a V-shape, without a central papilla. The COI gene sequences were plotted in the BOLD Systems platform, which confirmed the morphological identification of the species, with a 99.1% similarity in the male, and 99.4% in the female to existing sequences. This record extends the known distribution of T. nicefori in Brazil by approximately 310 km to the most eastern part of the Amazon Biome.
