  • Title
    Butterfly (Lepidoptera- Rhophalocera) Diversity in the Developing Urban Area of Gelephu, Bhutan
    Type
    Journal Article
    Description
    Urban development has led to substantial fragmentation of natural habitats of wildlife, depletion of water resources, and increase in air and soil pollution resulting in significant impact on biodiversity and ecological processes. Butterflies are good biological indicators of anthropogenic disturbance of environment. Considering the impact of habitat fragmentation and change in environment and climate variables, this study was undertaken to study butterfly diversity in and around the expanding Gelephu town in southern Bhutan. The survey was carried out from January to December, 2015 with an objec-tive to generate baseline information on the presence and status of butterflies in the urban area of Gele-phu. A total of 56 species of butterflies belonging to 5 different families were recorded. Family Nym-phalidae had the highest number of species (46%, n = 26) and the lowest was represented by family Papilionidae (5%, n = 3). Establishment of Green Park in the urban area could create good habitat for increasing butterfly biodiversity in urban area of Gelephu.

  • Title
    Taxonomic study of social vespid wasps (Hymenoptera: Vespidae: Vespinae & Polistinae) of Bhutan
    Type
    Journal Article
    Description
    15 species are reported as new records for Bhutan. Unlike other 14 species, Vespa fumida is treated as new record as the present geographical location of Padong is in the Indian state of Sikkim. Moreover, during the entire study period, Vespa fumida and Polistes (Stenopolistes) nigritarsus are reported only from Ngatshang, Mongar and Pasakha, Chukha respectively with single female specimen each. Recording species from single location may indicate its rareness in Bhutan, while Parapolybia varia is found commonly throughout Bhutan with altitudes ranging from 349 m to 2073 m. Dolichovespula lama has been reported from new altitudinal range of 1235 m above sea level. With exception of Vespula flaviceps, only females were caught and studied for Vespula vulgaris, V. structor and Dolichovespula lama. Therefore, the study of male specimens and the nest for Vespula vulgaris, V. structor and Dolichovespula lama are recommended.

    Eleven new species and one new record of black flies (Diptera: Simuliidae)from Bhutan
    Type
    Journal Article
    Description
    Eleven new species and one new record of black flies (Diptera: Simuliidae) are described on the basis of reared adult, pupal and/or larval specimens collected from Bhutan. They are assigned to four subgenera within the genus Simulium: Gomphostilbia (two new species), Montisimulium (two new species and one new record), Nevermannia (three new species of which one belongs to the feuerborni species-group and two to the vernum species-group), and Simulium (four new species of which two belong to the multistriatum species-group and two to the tuberosum speciesgroup). This study has increased the total number of simuliid species recorded from Bhutan from six to 18.

  • Title
    The first record of Amolops himalayanus (Anura: Ranidae) from Bhutan.
    Type
    Journal Article
    Description
    During a series of surveys carried out in areas of broadleaf forest in the eastern Himalayas in early spring, Amolops himalayanus was identified for the first time in Bhutan. Information is provided on the ecology, habitat, reproduction, and geographical distribution of the species together with notes on the water chemistry of the collection site. A brief synopsis is given of the morphological differences between A. himalayanus and A. formosus, with which latter species A. himalayanus is often confused. A. himalayanus has been reported hitherto from seven localities in northern India and Nepal but only the original description of the taxon from Darjeeling is based on incontrovertible data.

    Type
    Journal Article
    Description
    Seven species ofGarraare herein accounted for in Bhutan. Three new records of known species, G. arupi, G. birostris,andG. lissorhynchus,and two new species,G. bimaculacaudasp. nov. andG. parastenorhynchussp. nov., are reported from central and southern Bhutan.Garra bimaculacaudasp. nov. is most notably different from its congeners by the presence of two dark spots on the lobes of the caudal fin, having one spot on each lobe. Meristic and morphometric differences from northeastern Indian congeners exist as well.Garra parastenorhynchussp. nov. is differentiated from its congeners by the presence of a prominent, overhanging, club-shaped proboscis, and a suite of meristic and morphometric characters. Notes on the taxonomy are provided for some species. Notes are provided on the biology and ecology for most species, which have been inferred from field observations. Ranges are expanded for two recently described taxa from Northeast IndiaG. arupi, andG. birostris.A key is provided to the currently known species ofGarrawithin Bhutan.
