A new species of Hipposideros is described from South-East Sulawesi, Indonesia. Morphologically, it shows close affinities to Hipposideros papua but is substantially smaller. It is currently only known from Rawa Aopa Watumohai National Park, an area of semi-disturbed lowland rainforest, where it was the most common species of hipposiderid recorded. In this paper, data on its morphometrics and echolocation are included, along with a brief discussion of its ecology and reproductive biology.
Since its discovery, the taxonomic status of the only species of Kerivoula (Chiroptera: Vespertilionidae: Kerivoulinae) to be found on Taiwan has been confused. Previous studies have assigned this species to either Kerivoula hardwickii or K. titania, both of which occur on continental SE Asia. This uncertainty supports repeated suggestions in the literature that specimens of K. hardwickii collected and/or sampled across SE Asia are likely to represent multiple cryptic taxa. To address these issues, we combined new and existing data from the genus Kerivoula on Taiwan and continental Asia, and performed diagnostic analyses in steps. First, phylogenetic reconstructions based on mitochondrial and nuclear DNA revealed a well-supported group comprising all taxa currently recognized as K. hardwickii, together with the Taiwanese Kerivoula and Kerivoula kachinensis to the exclusion of all other congeneric species. Second, focusing on all members of this monophyletic clade (i.e., K. hardwickii complex) together with K. titania, we used multivariate statistical methods to separate taxa based on morphometric data. Our results provide strong evidence that among these bats, the Taiwanese Kerivoula is a new species that also occurs on continental Asia, for which we provide a formal description and name. In addition, we show that the subspecies K. hardwickii depressa should be elevated to species status. We discuss our findings and the caveats of this and similar studies.
A new species of Kerivoula is described. Currently, it is known only from Namdee Forest in southern Kachin State, Myanmar. Externally, superficially similar to Kerivoula papillosa and with a dentition comparable to that of Kerivoula lenis, it is distinguished by its flattened skull. It was collected in evergreen forest in an area that also includes some mixed deciduous forest, shifting cultivation, and bamboo groves.
We conducted surveys of bats in China between 1999 and 2007, resulting in the identification of at least 62 species. In this paper we present data on 19 species, comprising 12 species from the family Rhinolophidae and seven from the Hipposideridae. Rhinolophids captured were Rhinolophus affinis, R. ferrumequinum, R. lepidus, R. luctus, R. macrotis, R. siamensis, R. marshalli, R. rex, R. pearsonii, R. pusillus, R. sinicus and R. stheno. Because of extensive morphological similarities we question the species distinctiveness of R. osgoodi (may be conspecific with R. lepidus), R. paradoxolophus (which may best be treated as a subspecies of R. rex), R. huananus (probably synonymous with R. siamensis), and we are skeptical as to whether R. sinicus is distinct from R. thomasi. Hipposiderids captured were Hipposideros armiger, H. cineraceus, H. larvatus, H. pomona, H. pratti, Aselliscus stoliczkanus and Coelops frithii. Of these species, two rhinolophids (Rhinolophus marshalli and R. stheno) and one hipposiderid (Hipposideros cineraceus) represent new species records for China. We present data on species’ ranges, morphology and echolocation call frequencies, as well as some notes on ecology and conservation status. China hosts a considerable diversity of rhinolophid and hipposiderid bats, yet threats to their habitats and populations are substantial.
We studied the chiropteran diversity of Andaman Islands between July 2012 and January 2016 from 38 different localities spread throughout the islands. Our surveys revealed the presence of 17 species of bats. One species — lesser bamboo bat Tylonycteris pachypus — reported earlier could not be found during the present study. Our study adds four new species records (Andersen's roundleaf bat Hipposideros pomona, diadem roundleaf bat Hipposideros diadema, Indian pipistrelle Pipistrellus coromandra, and greater bamboo bat Tylonycteris robustula) for the Andaman Islands. A brief review of each species including details on its distribution (earlier and present), and external and craniodental measurements is provided. We also provide a database of echolocation calls for the Islands' echolocating bat fauna, and confirm the reliability of acoustic monitoring as a method to noninvasively document chiropteran diversity there. This database allows comparisons with taxa from the mainland that are currently considered conspecific, but which show acoustic divergence, and deserve further taxonomic study.
Recent studies have shown the importance of Myanmar for the conservation of bat diversity. In March–April, 2003, twenty-five localities in Kachin and Shan States and Mandalay and Sagaing Divisions in Upper Myanmar were surveyed using mist nets and harp traps. Of the twenty-three bat species collected, thirteen were recorded from two localities in Kachin State, one of which has already been described as a new species, Kerivoula kachinensis, and a further two (a Rhinolophus and a Kerivoula) are putative new species. Murina tubinararis, Murina cyclotis and Rhinolophus shameli were recorded for the first time in Myanmar for over 65 years, while our records of Rhinolophus stheno and Rhinolophus malayanus are the most northern localities for these species in Myanmar. Species are discussed individually with external, cranial and dental measurements summarised. We also present descriptive statistics for echolocation calls recorded from five taxa. This represents the first bat survey of northern Myanmar forests for nearly 70 years. Kachin is already known to support high biodiversity and these recent records confirm the importance of its forests for the conservation of Myanmar's mammal fauna.
A new species of woolly horseshoe bat in the Rhinolophus trifoliatus species group is described from Sabah in Malaysian Borneo. Two specimens from Central and West Kalimantan, Indonesia are referred to this species. A fourth specimen from western Thailand is referable to this species but on the basis of ~10% genetic divergence at the cytochrome oxidase-I gene is described as a separate subspecies. Morphologically and acoustically the two subspecies are similar. With a forearm length of 52.90–54.70 mm, a skull length of 24.27–26.57 mm and a call frequency of 49.2–50.0 kHz, the new species overlaps in size and call frequency with the sympatric R. trifoliatus. However, it differs significantly in having a dark noseleaf and a uniformly dark brown pelage, resembling, but being intermediate in size between R. sedulus and R. luctus, which have a skull length of 18.99–20.17 and 26.35–32.07 mm, respectively. It also differs from R. trifoliatus in the shape and size of the rostral inflation. It can be distinguished from R. beddomei (forearm length 55.00–63.44 mm) and R. formosae (forearm length 53.85–62.40 mm), which are endemic to the Indian Subcontinent and Taiwan, respectively, by its relatively smaller body size. Acoustic and genetic data are included in the comparison between the species. Both character states support the conclusions based on morphology. Further surveys in intact evergreen forest together with a re-examination of museum specimens may reveal that this species is widespread in Southeast Asia.
