Abstract
We report on the molecular phylogenetic position of the Western Ghats bronzeback, Dendrelaphis chairecacos (Boie, 1827), and new sightings from Dangs in Gujarat and Goa State in western India. Based on COI genes sequenced from two samples from Goa and the Dangs, we report that D. chairecacos was 5.59–5.60% (the total percentage of divergence is 5.77%), i.e. with an intraspecific variation of 0.67% nearly about 0.01%, divergent from D. tristis (Indian sample). Our record from the Dangs extends its range northwards by 350 km (from Satara) in the Western Ghats. We also used the geo-referenced and identified photo vouchers posted in citizen science portals to conduct a MaxEnt species distribution modelling for D. chairecacos for the first time. Our analysis run based on 27 data points including the new Dangs record and a previously published doubtful record from Yercaud (Southern Eastern Ghats), showed that the probability of occurrence in both these regions was very low (<20%). Areas in Malabar and the Konkan Coastal Plains from Kanyakumari to the Goa Gap had the highest probability of occurrence (>75%). We uphold the taxonomic ambiguity of the individual from Yercaud lacking loreal scale (as D. cf. chairecacos) and maintain that D. chairecacos s.str. is known only from the Western Ghats. We also re-identified a specimen (ZSI-R-22185) from Goa as D. chairecacos, which may be its earliest precise record from Goa (in 1969). Thus far based on nine preserved and two uncollected specimens mostly from the southern parts of its range, D. chairecacos stands better characterised based on 12 more live specimens, all from the northern parts of its range.

Abstract
Seven species of snakes described by Boie (1826) are currently recognized. They represent two families and six genera. Viperidae: Gloydius blomhoffii, and Colubridae: Hebius vibakari, Elaphe climacophora, E. quadrivirgata, Euprepiophis conspicillatus, Rhabdophis tigrinus, and Sibynophis geminatus. We provide the transcriptions and English translations of all seven original descriptions, which were originally written in Latin and German.

Abstract
Vanda tessellata is an indigenous, endangered, and protected orchid species with a wide range of flower variations in Sri Lanka. The plant has high ornamental and medicinal values and therefore faces serious threats due to over-exploitation and habitat destruction. Thus, sound knowledge of pollination biology is important in the conservation and propagation of the species. The current study investigates the diurnal and nocturnal pattern of pollinators’ behaviour with the volatile fragrance profile of V. tessellata. Gas chromatography-mass spectrometry (GC-MS) analysis was carried out to identify the odour profile. The detailed GC-MS results produce 65 peaks of 36 volatile compounds. The diurnal pollinator, Xylocopa tenuiscapa (order Hymenoptera) and the nocturnal pollinator, Daphnis nerii (order Lepidoptera) visitations to V. tessellata flowers and the intensity of floral odours were well correlated proving the ability of V. Tesselatta flowers to attract both diurnal and nocturnal pollinators for successful cross-pollination.
