    Diversity assessment and molecular characterization of the geometridae moths (Lepidoptera: Heterocera) in Nanda Devi Biosphere Reserve, Uttarakhand.
    (wildlife Institute of India, Dehradun, 2018) Dey, Pritha; Chandra, Kailash; Uniyal, V.P.
    The study aims to combine traditional morphological and modern molecular tools to answer the questions on diversity, the patterns and the factors governing the patterns. The study was conducted in Nanda Devi National Park area which is a part of the Nanda Devi Biosphere Reserve (NDBR), Uttarakhand, India. The study area (Nanda Devi Biosphere Reserve) was stratified on the basis of elevation & vegetation and sampled at every 200m along the elevation between 2000-3800m. Two mountain gradients 1) Joshimath and 2) Data were chosen for a comparative study. DNA extraction and sequencing were performed at the CCDB, University of Guelph. Sequences of further specimens from the Zoologische Staatssammlung München from western Himalaya (Himachal Pradesh and Kashmir) and eastern Himalaya (Sikkim) were included into the analysis. Our results revealed one new species (Prometopidia sp. nov.), one new distribution record for India (Alcis paghmana) and considerable distribution extensions of 15 other species within India. Four species from Sikkim show deep genetic divergences (K2P distance) from conspecifics, indicating potential crypsis
