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.

Five new species of geckos are described from Sri Lanka by morphological comparison and morphometric analysis leading to review the genus Cnemaspis in the country. The type series of these species were identified from following localities: C. alwisi and C. kumarasinghei from the intermediate zone, C. retigalensis from the dry zone, C. molligodai from the lowland wet zone and C. samanalensis from the mountain region of the wet zone in the country. The high degree of endemicity (90%) shown by Cnemaspis in Sri Lanka could be attributed to geographical isolation. In addition, the taxonomic issue of C. jerdonii scalpensis is discussed and the species C. scalpensis is errected.

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.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.

A new species of Cnemaspis Strauch is described from Knuckles Range of Sri Lanka. This new species had been previously confused with Cnemaspis podihuna Deraniyagala. Cnemaspis kandambyi sp. nov. closely resembles C. podihuna and C. molligodai Wickramasinghe & Munindradasa. Cnemaspis kandambyi sp. nov. differs from C. podihuna by having 7–8 (versus 3–6) unpored scales in each side of the precloacal-femoral pores row, lacking (versus having) an internasal scale, body (axilla to groin) relatively long 47.7–48.3 (versus 38.1–38.7)% of SVL and dorsum dark brown (versus bright yellow). Cnemaspis kandambyi sp. nov. also distinguished from C. molligodai by having 4 (versus 5) precloacal pores, 5–6 (versus 7–9) femoral pores on each side, precloacal pores not in an inverted V-shaped arrangement (versus in inverted V-shaped arrangement), lacking (versus having) a distinct black marking on nape and a black lateral stripe begins behind eye extends laterally beyond the origin of forearm (versus not extending beyond the origin of forearm). Additionally, Cnemaspis kandambyi sp. nov. and C. molligodai show discrete distribution: former restricted to Knuckles Range and the latter confined to Lowland wet zone of Sri Lanka. We confirm that, no type material of Cnemaspis podihuna survive in the current collection of the National Museum of Sri Lanka.
