Lyriothemis defonsekai van der Poorten, 2009 is a nationally Critically Endangered odonate species in Sri Lanka.  It is endemic to the country and was known only from the type locality, Kudawa, Sinharaja Forest Reserve and its vicinity thus it was considered to be a point endemic.  We report the first ever record of the species outside Sinharaja extending the known range of the species.  The present observations were recorded from Yagirala Forest Reserve where an immature male and one or two mature females of the species were observed.  We also discuss the observations on its habitat and distribution range.

Ayerbe’s snail-eater Sibon ayerbeorum is a nocturnal, tree-dwelling snake which was recently described based on four specimens collected in the proximity of Munchique National Natural Park, department of Cauca, Colombia, above 1000 m altitude. We here expand the distribution range of S. ayerbeorum into the department of Chocó, Colombia. The new record extends the distributional range of the Ayerbe’s snail-eater by nearly 288 km in a straight-line north-western ward from its type locality and is more than 1000 m below it.

A New Species

A new species of frog tentatively assigned to the genus Polypedates is described from the Gilimale forest reserve of theSabaragamuwa province of Sri Lanka. This tree frog is characterized by unique osteological characteristics in the skullwhich distinguish it from all other congeners, such as the presence of a series of maxillary teeth progressively changingorientation from horizontal to vertical from posterior end to anterior; a laterally-curved spine in the quadratojugal bone;and bony co-ossification on the skull resulting in four dorsal spines which are externally seen as protrusions in the parietalarea. Bioacoustic observations of Polypedates ranwellai sp. nov. revealed three distinct call types. High rates of deforestation and anthropogenic activities at the type locality threaten the survival of the species.

Distribution of Kerivoula hardwickii, Hardwicke's woolly bat, in Sri Lanka is restricted to the central highlands and to northeastern region of the country, and so far, only recorded from four distinct locations. In Sri Lanka, this species was last documented in the year 1994, and no subsequent surveys recorded this species in Sri Lanka, thus considered rare in Sri Lanka. In contrast, within its southern Asian biogeography, K. hardwickii is widely distributed, particularly in Southeastern Asia. In this study, a single male of K. hardwickii was observed in lowland rainforest ecoregion of Sri Lanka near Labugama-Kalatuwana Forest Reserve where the bat was roosting on a curled live banana frond. The bat was roosting 1.8 m above the ground. This was the first instance K. hardwickii was recorded in the lowland rainforests of Sri Lanka, which extends this species’ biogeography of Sri Lanka into the lowland wet zone. Thus, distribution range of K. hardwickii in Sri Lanka could be broader than historically documented. However, intensive surveys, particularly in lowland rainforest region, are required to validate the true distribution of this bat in Sri Lanka.

This paper is based on the observations from Tamil Nadu. The presence of this critically endangered Theraphosidae, P. metallica has been recorded for the first time outside of its known distribution, wherefore, expanding its range to further south from its type locality. The present sighting extends its distribution ranges along the Eastern Ghats by approximately 370 Km to further south from its type locality (Pocock 1899).

A New Species

Elatostema monandrum var. rigidiusculum, confined to the Bambarabotuwa Forest Reserve in Sabaragamuwa province of Sri Lanka, is reclassified to the rank of species as E. rigidiusculum. We compare it to the morphologically most similar, E. monandrum. The main diagnostic features of E. rigidiusculum are obovate leaves 0.3–1.5 cm long whose laminae are apically crenate, and the presence of sessile receptaculate involucrate inflorescences in both sexes. The proposed IUCN conservation status of E. rigidiusculum is Critically Endangered (CR).

Carbon dioxide has gained lot of attention in recent past as a greenhouse gas, and therefore it has a potential to affect the climate pattern of the world. Several anthropogenic activities are known to be responsible for the increased level of carbon in the atmosphere and disruption of the global carbon cycle. However, nature has its own mechanism of sequestering and storing the carbon in its “reservoirs”. Forest has the ability to sequester carbon in their biomass and reduce the rate of increase of atmospheric carbon dioxide. The carbon sequestered in the forest trees are mostly referred to as the biomass of a tree or a forest. It has been identified five carbon pools of the terrestrial ecosystem, involving biomass. The study was designed to estimate biomass stock and then the carbon stock of the Udawattakele Forest Reserve (7°17'58 "N, 80°38'20’’E) in Kandy, Sri Lanka. Allometric equations were used to calculate biomass of trees. The total biomass stock was estimated to be 9475.56 t ha-1 (Mega gram-Mg) and the total carbon stock was estimated to be 4,453.55 t ha-1 (Mg) in the Udawattakele Forest Reserve (UFR). This amount is equivalent to 16,344.52 Mg of carbon dioxide in the atmosphere. UFR holds a moderate amount of biomass/carbon stock and the total carbon density of natural forest and plantations was found to be 36.55 Mg ha-1 and 44.89 Mg ha-1 respectively.
