Abstract

A new genus and species of fossil bat is described from New Zealand’s only pre-Pleistocene Cenozoic terrestrial fauna, the early Miocene St Bathans Fauna of Central Otago, South Island. Bayesian total evidence phylogenetic analysis places this new Southern Hemisphere taxon among the burrowing bats (mystacinids) of New Zealand and Australia, although its lower dentition also resembles Africa’s endemic sucker-footed bats (myzopodids). As the first new bat genus to be added to New Zealand’s fauna in more than 150 years, it provides new insight into the original diversity of chiropterans in Australasia. It also underscores the significant decline in morphological diversity that has taken place in the highly distinctive, semi-terrestrial bat family Mystacinidae since the Miocene. This bat was relatively large, with an estimated body mass of ~40 g, and its dentition suggests it had an omnivorous diet. Its striking dental autapomorphies, including development of a large hypocone, signal a shift of diet compared with other mystacinids, and may provide evidence of an adaptive radiation in feeding strategy in this group of noctilionoid bats.

[Mammalogy • 2018] Uncovering the Diversity of Dog-faced Bats from the Genus Cynomops (Chiroptera: Molossidae), with the Redescription of C. milleri and the Description of Two New Species; Cynomops freemani & C. tonkigui ---ScRaBBlE

Abstract

Until recently the genus Cynomops (Chiroptera: Molossidae) comprised six species of fast flying, aerial insectivorous bats distributed throughout the Neotropics. However, our revisionary study have shown that the diversity of this taxon was underestimated as molecular and morphological data supported the recognition of C. milleri as a full species and revealed two previously unrecognized, small species of Cynomops. These newly recognized taxa are Cynomops freemani sp. nov. from the Canal Zone region, Panama, sister taxon to C. mexicanus, and Cynomops tonkigui sp. nov. from the eastern Andes of Ecuador and Colombia, sister taxon of C. milleri. We also describe the calls of Cynomops freemani sp. nov. that may be useful for the recognition of these species during field inventories based on ultrasonic recording techniques. We elevate the currently known diversity of Cynomops to eight species, as we also revalidate C. milleri providing an emended diagnosis and a redescription of this taxon.

[Mammalogy • 2018] Cassistrellus gen. nov. • A New Genus and Species of Vespertilionid Bat from the Indomalayan Region: Cassistrellus dimissus & C. yokdonensis ---ScRaBBlE

Cassistrellus dimissus (Thomas, 1916)

Ruedi, Eger, Lim & Csorba, 2018

 DOI: 10.1093/jmammal/gyx156

Abstract

Bats belonging to the subfamily Vespertilioninae are diverse and cosmopolitan, but their systematic arrangement remains a challenge. Previous molecular surveys suggested new and unexpected relationships of some members compared to more traditional, morphology-based classifications, and revealed the existence of taxonomically undefined lineages. We describe here a new genus and species corresponding to an enigmatic lineage that was previously identified within the genus Eptesicus in the Indomalayan Region. Phylogenetic reconstructions based on mitochondrial and nuclear genes relate the new taxon to Tylonycteris and Philetor, and show that specimens associated with this new genus represent 2 genetically distinct species. Although little is known about their ecology, locations of capture and wing morphology suggest that members of this new genus are tree-dwelling, open-space aerial insect predators. The new species has only been documented from Yok Don National Park in Vietnam, so its conservation status is uncertain until more surveying methods target the bat fauna of the dipterocarp forest in Southeast Asia.

Key words: eptesicoid bats, phylogeny, systematics, taxonomy, Vespertilionidae

Numbers near nodes indicate branch support (left, percent ML bootstrap, right, posterior probability), while solid circles represent nodes recovered in >98% of both resampling methods. The gray box highlights the strongly supported clade comprising species of Cassistrellus gen. nov., Tylonycteris, and Philetor.

 DOI: 10.1093/jmammal/gyx156

Cassistrellus gen. nov.

Type species: Eptesicus dimissus Thomas, 1916

Description: Species of Cassistrellus are medium-sized vespertilionids (FA 39–47 mm; body mass 12–17 g) characterized externally by short, chestnut-brown pelage that is paler on the ventral parts, by narrow wings with short and pointed tips, and an especially broad muzzle (Fig. 2). Wing membranes are attached to the middle or distal parts of the metatarsus. The tail is mostly included in the uropatagium and extends by 2–3 mm beyond its posterior margin. The calcar extends less than halfway to the tail and may have a small lobe near the ankle. The skull is robust and angular in profile making an almost straight line between the rostrum and the occipital region. It is characterized by well-developed sagittal and lambdoid crests, which meet near the top of the skull to form an occipital helmet. On its ventral surface, the skull has a pair of deep and well-delimited basisphenoid pits located between the cochleae (Fig. 3). Laterally, the lachrymal region has prominent preorbital processes, but the supraoccipital ridges are weak and barely visible. The dental formula is  2113/3123 = 32  teeth, with the upper canines possessing a distinct secondary cusp along the rear edge (Fig. 3).

Etymology: The name Cassistrellus derives from the Latin noun “cassis”, which means wearer of a helmet, in reference to the shape of the hind parts of the skull. The suggested English vernacular name is helmeted bat.

Geographic distribution: The type specimen of C. dimissus was collected by H. C. Robinson and E. Seimund in Kao Nawng, Bandon (currently within Tai Rom Yen National Park in Surat Thani province of Thailand) at 1,400 feet (= 436 m a.s.l.), in June 1913 (Robinson and Kloss 1915). However, the altitude associated with this specimen was reported by Thomas (1916) as 3,500 feet (= 1,067 m a.s.l.), which would correspond to near the summit of the Khao Nong mountain, where the collectors did not capture bats. As all known localities of Cassistrellus are located in the lowlands at elevation between 190 and 674 m a.s.l., these bats should be indeed regarded as lowland dwellers. The vast area covered by the few scattered records of Cassistrellus suggests that it should be widely distributed from the Isthmus of Kra into mainland Southeast Asia and the foothills of the Himalaya, i.e., across most of the Indo-Burma biodiversity hotspot (Myers et al. 2000a). All capture sites were situated in hilly terrain with mixed deciduous or dipterocarp forests traversed by large rivers.

Cassistrellus yokdonensis sp. nov.

Yok Don helmeted bat

Eptesicus sp. A JLE-2010: Francis et al., 2010

Holotype: Male ROM 107751 (field number 42734) collected on 6 June 1997 by B. K. Lim and M. Theberge. Preserved as a skin, skull, and partial skeleton. Epiphyses almost completely fused, indicating that this bat was a subadult.

Type locality: Vietnam: Dak Lak province; Yok Don National Park, Dak Ken River (tributary of the Serepok River), base of Yok Mt. ..., at 194 m a.s.l. in dry, open dipterocarp forest.

Diagnosis: Cassistrellus yokdonensis sp. nov. is a medium-sized vespertilionid bat (body mass about 15 g) characterized by pointed, narrow wings similar in shape to those of Nyctalus species, but not as narrow. The fur is sparse with short hairs, clove brown (Ridgway 1912) dorsally, lighter beige ventrally, and cream colored at the throat. There is no glossy tinge to the fur. The color of the wings and other skin parts is blackish brown. The wing membranes attach to the distal end of the metatarsus. The calcar extends less than halfway to the tail and has no visible lobe.

Although the dental formula is identical to that of Eptesicus species, the skull possesses a pair of deep and well-defined basisphenoid pits and prominent preorbital processes that are otherwise absent from the latter genus. C. yokdonensis sp. nov. is morphologically similar to C. dimissus, but—in spite of the fact that the known individuals are not fully grown adults—is substantially larger, both externally (e.g., FA 47 mm versus 39–42 mm; Table 1), and cranially (e.g., maxillary toothrow length over 6.5 mm versus less than 6.4 mm). C. yokdonensis sp. nov. has also a much stronger dentition in general, and subequal small lower premolars, longer more curved upper canines, and procumbent upper incisors compared to its congener. Genetically, C. yokdonensis sp. nov. has unique mitochondrial (Cytb, Co1) and nuclear (Rag2) sequences compared to C. dimissus from Laos.

Etymology: We propose the name C. yokdonensis after the national park where it has been found, in recognition of the importance of protected areas in conserving species and their habitats.

Geographic distribution: Currently known only from Yok Don National Park, Dak Lak Province of Vietnam. The 2 specimens were caught shortly after 2100 h as they flew into large (30 m long by 10 m high) canopy nets deployed in a dry, open dipterocarp forest of lowland regions. Other species of mammals caught in the same nets included Taphozous, Pipistrellus, Murina, Cynopterus, Megaerops, and Rhinolophus bats and several Hylopetes flying squirrels. In addition, a paratype specimen of a new species of parachute gecko (Ptychozoon trinitaterra) was caught in this net (Brown 1999).

[Mammalogy • 2017] Caribbean Myotis (Chiroptera, Vespertilionidae), with Description of A New Species, Myotis attenboroughi, from Trinidad and Tobago ---ScRaBBlE

Myotis attenboroughi

Moratelli, Wilson, Novaes, Helgen & Gutiérrez, 2017 

DOI: 10.1093/jmammal/gyx062   

facebook.com: TriniBats 

Abstract

We describe a new species of Myotis (Vespertilionidae, Myotinae) from the Republic of Trinidad and Tobago, Tobago Island. The new species (Myotis attenboroughi sp. nov.) can be distinguished from all other Neotropical congeners by cranial features and cytochrome-b gene sequences. Myotis attenboroughi sp. nov. is allied morphologically with species in the albescens group (like M. nigricans), and is sister to a clade including M. cf. handleyi, M. nesopolus, and 3 possibly undescribed species from Central and South America. A review of Myotis collections from the Caribbean confirms M. nyctor for Barbados and Grenada; M. dominicensis for Dominica and Guadeloupe; M. martiniquensis for Martinique; M. pilosatibialis and M. riparius for Trinidad; and M. attenboroughi for Tobago. The occurrence of M. attenboroughi on Trinidad is still an open question.

Keywords: Caribbean, Lesser Antilles, Myotis attenboroughi, Myotis nigricans, Neotropics, Sir David Attenborough’s Myotis

The newly described, Sir David Attenborough's Myotis —Myotis attenboroughi—(Moratelli et al.,2017), represents the first, and only known, endemic mammalian species on the islands of Trinidad and Tobago. Molecular, morphological and morphometric analyses conducted by Moratelli et al., now confirms that the Black Myotis on Tobago (see photo), traditionally assigned, Myotis nigricans, is actually a previously unknown species now named, Myotis attenboroughi, in honour of famed naturalist, Sir David Attenborough. This tiny bat, the Sir David Attenborough's Myotis, Trinidad and Tobago's only known endemic mammalian species, consumes moths and other small flying insects. This species is known to roost in caves, tree-hollows, and if neither of these is available, the attics of buildings.

Why isn't the bat named for Tobago? In this particular case, this new designation is a result of a species split (simply put). In zoological nomenclature, this occurs when new findings warrant a species being split into subspecies or new species, which is the case here. If this specimen described for Tobago was indeed an originally described, nominal species, as distinct from a species or subspecies subsequently distinguished from it, then it may be named Tobagoi or Trinitatis (as some local bats are named), or something along those lines.

Describimos una nueva especie de Myotis (Vespertilionidae, Myotinae) de la República de Trinidad y Tobago, isla de Tobago. La nueva especie (Myotis attenboroughi sp. nov.) se distingue de otros congéneres Neotropicales en sus rasgos craneanos y secuencias del gen citocromo b. Myotis attenboroughi sp. nov. es morfológicamente similar a especies del grupo albescens (tal como M. nigricans) y es hermana de un clado que incluye a M. cf. handleyi, M. nesopolus, y tres especies, posiblemente no descritas, de Centro y Sud América. Una revisión de las series de Myotis del Caribe confirma a M. nyctor para Barbados y Granada; M. dominicensis para Dominica y Guadalupe; M. martiniquensis para Martinica; M. pilosatibialis y M. riparius para Trinidad; y M. attenboroughi para Tobago. La presencia de M. attenboroughi en Trinidad sigue siendo hoy un enigma.

Singular bat Zoologists have named a newly discovered species of bat after the veteran British naturalist and broadcaster David Attenborough. Scientists analysed museum records of specimens of 377 Caribbean bats, and found that a species apparently endemic to the island of Tobago is morphologically and genetically different from the mainland species (Myotis nigricans) to which it had been assigned taxonomically for almost a century. Taxonomist Ricardo Moratelli and his team named the bat (pictured) Myotis attenboroughi in honour of the naturalist, who has inspired generations of wildlife biologists. The findings were published on 7 June (R. Moratelli et al. J. Mammal. http://doi.org/b78; 2017).

Abstract

A new species of Murina of the suilla-type is described from the Hkakabo Razi Landscape, Kachin, Upper Myanmar, an area that is currently being nominated as a World Heritage Site. The new species is a small vespertilionid, with a forearm length of 29.6 mm, and is very similar to M. kontumensis, which was recently described from Vietnam. However, it is distinguishable by a combination of external and craniodental morphology and genetics. The DNA Barcode reveals that the new species clusters sisterly to M. kontumensis but with a genetic distance of 11.5%. A single known specimen of the new species was collected from a lowland forest area in the plains of the Hkakabo Razi landscape, south-eastern Himalaya. Additional information on ecology, echolocation, and conservation are included. The high cryptic diversity of the genus Murina in Southeast Asia, as well as the Hkakabo Razi Landscape being a bat diversity hotspot, is highlighted.

Etymology. The species is named after the Hkakabo Razi Landscape, where the only known specimen was collected. The proposed English name is ‘Hkakabo Razi Tube-nosed Bat’

Ecology and distribution. The new species, M. hkakaboraziensis sp. nov., was collected in a mist net set at the edge of a lowland semi-evergreen forest at the transition zone to an open space grassland, which undergoes an annual burn (Fig. 5). The new species was the only bat captured in the mist net. However, on the same night, four other insectivorous bats, Rhinolophus affinis, R. pusillus, Aselliscus stoliczkanus and Hipposideros pomona were captured in nearby mist nets and harp traps. Four other vespertilionids, M. cyclotis, M. feae, M. cf. eleryi, Kerivoula hardwickii, and K. furva were also captured in the same area on other nights. Currently, the new species is only known from the holotype collected from the type locality in the Hkakabo Razi Landscape, Kachin, northern Myanmar.

Discussion:

The discovery of Murina hkakaboraziensis sp. nov., as well as a recently described Kerivoula furva (Kuo et al. 2017), indicates that the Hkakabo Razi Landscape is extremely understudied in terms of bats. Based only on a single scientific expedition in 2016, 37 species of bats were recorded from HRL (P. Soisook, unpublished data) representing approximately 40% of bats in Myanmar. Nevertheless, the 2016 expedition focused only on a limited geographical area and elevation of the HRL. Future surveys to cover the variety of habitats, particularly at the higher elevations, would be of interest. 

The vespertilionid community in the HRL appears to be a geographical connection and a unique mix of species those found widespread in the Indochinese Region (e.g. M. cyclotis, M. feae, M. cf. eleryi, K. kachinensis, K. hardwickii, and K. furva), and those from the Indian Region (e.g. M. cf. jaintiana, M. cf. pluvialis). It indicates the importance of primary forests, and ongoing biogeographical processes of the HRL, underlining the significance of Myanmar’s endeavour to nominate the area as a Natural World Heritage Site.
