Taxonomic and distributional assessments of chaerephon plicatus from Vietnam

This paper provides taxonomic and ecological assessments with an emphasis on morphological measurements, colony size, roosting habitats and national distributional range of Wrinkle-lipped Bat within Vietnam. | TAP CHI SINH HOC 2014, 36(4): plicatus 479-486 Taxonomic and distributional assessments of Chaerephon DOI: 10.15625/0866-7160/v36n4.5980 TAXONOMIC AND DISTRIBUTIONAL ASSESSMENTS OF Chaerephon plicatus (Chiroptera: Molossidae) FROM VIETNAM Vu Dinh Thong Institute of Ecology and Biological Resources, VAST, vietnambat@gmail.com ABSTRACT: To date, Wrinkle-lipped Bat (Chaerephon plicatus) is the only species of the family Molossidae in Vietnam. It is found throughout much of Asia but rarely recorded in the country. Every published record of this species from Vietnam was only resulted from a single individual with little data on morphology. Particularly, the previous publications did not include any information about either colony size or roosting site of the species within Vietnam. Between 2001 and 2014, a series of field surveys was conducted throughout the country with an intensive search for free-tailed bat species. The obtained results indicate that Wrinkle-lipped Bat is a widespread bat species but its known roosting sites in Vietnam are quite distjunct. Its colony size is in both seasonal and geographical variations ranging from several hundreds to over three million individuals. The species inhabits seasonally and permanently in northern and southern regions, respectively. This paper provides taxonomic and ecological assessments with an emphasis on morphological measurements, colony size, roosting habitats and national distributional range of Wrinkle-lipped Bat within Vietnam. Keywords: Asia, behavior, free-tailed bat, habitat, Mammalia, seasonal variation. INTRODUCTION Wrinkle-lipped Bat (Chaerephon plicatus) is a free-tailed species, which was originally described as Vespertilio plicatus (Buchannan 1800). Subsequently, the species was reclassified as Tadarida (Chaerephon) plicata [1, 6], Chaerephon plicata [2, 12] and Chaerephon plicatus [5, 9]. Freeman (1981) [10] delineated that Tadarida and Chaerephon are two distinct genera. This paper identifies .
