COVER-DEPENDENCY OF ANURANS IN THE RIVERSTONE, KNUCKLES MOUNTAIN FOREST RANGE, SRI LANKA
Senarathge R. Weerawardhena* & Anthony P. Russell *Corresponding author. E-mail: zoosrw@kln.ac.lk
Abstract The species composition of anurans was studied in the disturbed and undisturbed sub-montane forest habitats in the Riverstone of the Knuckles Mountain Forest Range of Sri Lanka. Twenty one anuran species were encountered. The distribution pattern of collected anuran species was related to the percentage of vegetational cover and they were categorized in relation to dependency on the vegetational cover.

Abstract Physoschistura tuivaiensis is described from Likhailok on the Tuivai River, a tributary of the Brahmaputra River in southern Manipur, India. It is distinguished from congeneric species except P. shanensis and P. yunnaniloides by having a complete lateral line. It can be distinguished from those two species by the presence of 12-14 dark olivaceous blotches on the flank, and 15-17 dark olivaceous saddles on the back, more branched caudal fin rays, and 4+8 pores in the infraorbital canal. Examination of the holotype of Physoschistura elongata shows lip morphology different from Physoschistura, and the species is referred tentatively to Schistura.

Whereas biological systematics and taxonomy are probably about the same kind of scientific enterprise, they were separated by Ernst Mayr in his classical text book, and taxonomy became cemented as a subset of systematics. A little over 40 years have passed since these definitions were expressed, and the work in which they appeared has become obsolete with the appearance of new technology and new philosophy about what are the fundamental aspects of species and higher taxa, especially with the development of phylogenetic systematics and facility of studying factors of inheritance at molecular level. Nevertheless, biological systematics remains the fundamental powerful scientific domain for understanding and expressing biological diversity, and keeps its definitions.

Rhinolophus rouxii and Hipposideros speoris are small-sized bats belonging to the Rhinolophidae and Hipposideridae families, respectively. Rhinolophus rouxii is widely distributed in Sri Lanka, India, Nepal, China and Vietnam, whereas H. speoris is found in Sri Lanka, India and more recently reported from Myanmar. These two species are listed as of Least Concern in both Global and National Red Lists of IUCN. As per the existing distribution records, they are commonly found in the low country: R. rouxii up to an elevation of 1,590 m, whereas H. speoris is at altitudes ranging up to 1,385 m.
