Abstract We describe a new species of the genus Tylototriton from Pu Hoat Nature Reserve, Nghe An Province, in the northern part of Central Vietnam, based on morphological and molecular evidence. The new species was previously confused with T. vietnamensis from northern Vietnam and T. notialis from Laos. The new species can be distinguished from T. notialis by the absence of orange coloration on posterior end of parotids (vs presence); an indistinct brown coloration on rib nodules (vs bright orange); a broader and slightly rounded head (vs narrower and angular); comparatively shorter limbs (vs longer); slightly fewer number, smaller size and irregular arrangement of rib nodules (vs larger rib nodules arranged in two dorsolateral series). Phylogenetic analysis of the ND2 and 16S rRNA mtDNA genes confirmed the placement of the new species to Clade I of the subgenus Yaotriton, and suggests it is a sister species of T. notialis (p-distance 3.0% in ND2 gene). The range of the new species is restricted to the Pu Hoat Mountain Range and is isolated from the range of T. notialis, which inhabits Northern Annamites (Truong Son) Mountains by the valley of the Ca River, an important biogeographic barrier. The new species is currently known only from the montane forests of Pu Hoat Nature Reserve (at elevations from 700 to 1000 m a.s.l.). We suggest the new species be classified as Endangered (EN) on the IUCN Red List.

EDITORIAL : Covid-19, biodiversity conservation and welfare of wild animals partially under human control
Vincent Nijman Section Editor: Taprobanica, the journal of Asian Biodiversity
It would feel wrong if I did not start this editorial with Covid-19 and its impact on biodiversity conservation in the broadest sense. There is no doubt that little will have had as much impact on biodiversity conservation throughout Asia as the Covid-19 pandemic. National and regional lockdowns, a shutdown of international travel, trade restrictions, temporary shutdowns of wet markets as well as live animal markets, closures of zoos and animal parks, closures of national parks to tourists, restriction of budgets for conservation agencies, etc.

The tallest canopy and the highest carbon stock for a forest stand in Sri Lanka

The height of the canopy of a forest has been noted as an important structural parameter in characterizing particular forest types in Sri Lanka. However, only limited studies have been carried out on the carbon stocks of different natural forest types, which is also an important structural parameter of forests. As per the scientific literature mentioned above, the tallest canopy forests are wet zone lowland rain forests in the south western part of the country. The forests are dominated by trees of the family Dipterocarpaceae and reach a maximum canopy height of 45 m. A preliminary botanical survey conducted in the hitherto unexplored Udakeeruwa forest in the eastern intermediate zone climatic zone, in Badulla district, revealed an unusually tall canopy of a natural forest patch dominated by dipterocarp trees.
The Dubai Desert Conservation Reserve (DDCR) is a 225 km2 natural reserve in the Emirate of Dubai in the United Arab Emirates. It was established in 2002 and comprises some 5% of the Emirate of Dubai's total landmass (DDCR 2020). It is home to many species of fauna and flora, including introduced Arabian mountain gazelles (Gazella gazella).

Chocolate pipistrelle (Hypsugo affinis) from Hantana, Sri Lanka, after 87 years

The Chocolate pipistrelle, Hypsugo affinis, is a comparatively small vesper bat (Chiroptera: Vespertilionidae) distributed in India, central Nepal, southern China, northeast Myanmar and the central highlands of Sri Lanka; its altitudinal range ascends up to 2,000 m a.s.l. In Sri Lanka, it has only been documented at three localities: West Haputale (~1,400 m), Ohiya (~1,700 m) and Nuwara Eliya (~1,900 m), but has not been recorded in the country since 1933. The National Red List for Sri Lanka listed it as Critically Endangered, although H. affinis is listed as of Least Concern in the IUCN Global Red List because of its wide occurrence across southern Asia. Herein we document the first observation of H. affinis from Sri Lanka after 87 years, including the first photographic evidence and the first roosting site observation.
