  • Title
    Erhaia Davis & Kuo (Gastropoda, Rissooidea, Amnicolidae) also in Bhutan
    Type
    Journal Article
    Description
    The occurrence of at least one species of Erhaia in Bhutan, viz. Erhaia wangchuki sp. n., is confirmed by DNA sequencing. A second unnamed species from Bhutan, that might be congeneric, is known from only a single shell. According to the molecular analysis, E. wangchuki is most closely related to a still undescribedErhaia species from China. These two species together with E. jianouensis and Akiyoshia kobayashii,both also from China, form a well supported clade. Awaiting additional molecular data, the apparent inconsistency regarding Erhaia versus Akiyoshia is not dealt with here. The extant true sister species of E. wangchuki could be among the four SE Himalayan species from Bhutan and Nepal that are classified with Erhaia on the basis of conchological data only.

  • Title
    Rediscovery of Ludlow's Bhutan Glory, Bhutanitis ludlowi Gabriel (Lepidoptera: Papilionidae): morphology and biology
    Type
    Journal Article
    Description
    The papilionid butterfly,Bhutanitis ludlowi, Gabriel, was rediscovered after a lapse of 76 years since it was first collected in Trashiyangtse Valley of Trashi Yangtse, eastern Bhutan. The immature stages of this butterfly are recorded and illustrated for the first time. The morphology and biology of adult, egg and larval stages are compared with those of theBhutanitisspecies, in particularBhutanitis lidderdaliiAtkinson.Aritolochia griffithii(Aristolochiaceae) is recorded as the larval hostplant ofB. ludlowi.The habitat, conservation needs and biogeography of the butterfly are also briefly discussed.

  • Title
    Primates of Bhutan and Observations of Hybrid Langurs
    Type
    Journal Article
    Description
    Six, possibly seven, species of non-human primates occur in Bhutan: slow loris (Nycticebus bengalensis), Assamese macaque (Macaca assamensis), Rhesus macaque (Macaca mulatta), Hanuman langur (Semnopithecus entellus), golden langur (Trachypithecus geei), and capped langur (Trachypithecus pileatus). A variant of the Assamese macaque, named Macaca munzala, has also been recorded there. Natural hybrids between golden and capped langur occur in an area in south-central Bhutan. The Assamese macaque is the most abundant and widespread primate, while slow loris is the least abundant, with a small range in Bhutan. Primates are not hunted for food in Bhutan, there are large areas of contiguous habitats for primates, and there is, besides, a good network of protected areas in the country. Overall, it would appear that primates have a secure future in Bhutan. The main conservation issues come from development, such as the construction of road networks and hydroelectric projects, grazing by domestic stock in some areas at high elevations, and people living in protected areas.

  • Title
    A preliminary report on the reptile fauna of the Kingdom of Bhutan with the description of a new species of scinid lizard (Reptilia: Scinidae)
    Type
    Journal Article
    Description
    The herpetofauna of the Kingdom of Bhutan has been poorly studied and few collections of Bhutanese reptiles have been made. Reptiles collected by the 1972 expedition of the Naturhistorisches Museum Basel (Switzerland) are presented as a basis for a preliminary species list for this eastern Himalayan country. Specimens representing seven families and 18 species were examined. Included is a new species of scincid lizard of the genus Mabuya. An additional five species have been reported from Bhutan and numerous other taxa are known from adjacent regions of Sikkim and Assam. Most of the fauna is pan-oriental in derivation and is widespread to the east, west and south. A number of species, however, are primarily Indo-Chinese in their affinities and extend only as far west as eastern Nepal. Collections from eastern Bhutan and from elevations over 1500 m are particularly small and additional field work will be required to provide a complete picture of the reptiles of the country.

  • Title
    Additions to the herpetofauna of Royal Manas National Park, Bhutan, with six new country records
    Type
    Journal Article
    Description
    We present the results of a rapid herpetofaunal inventory conducted in Royal Manas National Park, Bhutan, in June 2014. Visual encounter surveys, opportunistic searches, and pitfall traps were used during four days of fieldwork to document diversity. Twelve species of amphibians and 20 species of reptiles were recorded during the survey. Six species (Uperodon globulosus, Ingerana borealis, Calotes maria, Cnemaspis assamensis, Ptyctolaemus gularis, Trimeresurus properirum) are new additions to the herpetofauna of Bhutan.

    Mosses of Bhutan 11: A checklist of the mosses of Bhutan
    Type
    Journal Article
    Description
    A checklist is given of the mosses of Bhutan based on published reports. Totals of 156 genera and 282, species are recorded. The main past collectors of mosses in Bhutan are listed, together with sources of erroneous reports; 44 erroneous and doubtful taxa are excluded. The name Breutelia setschwanica is applied to the only Himalayan member of the genus. The name Barbula [lavicans is proposed as an avowed substitute for the illegitimate Tortula flavescens Hook. & Grev. (Barbula fuscescens C. Mull. nom. inval.)

    Type
    Journal Article
    Description
    Opportunistic survey of dragonfly diversity and distribution was done in Toebirongchhu sub-watershed within Punakha Dzongkhag, Western Bhutan to give updated list of species within the study area and the Dzongkhag, and update the species list for Bhutan. Total of 24 species belonging to 19 genera and 11 families were recorded of which 22 species are new record for the study area, 20 species for the Punakha Dzongkhag and 1 for Bhutan. The updated list of species for Punakha Dzongkhag is 28 species and for Bhutan is 85 species. Important records are Anisogomphus caudalis a Data Deficient species and a new record for Bhutan, Aristocypha (Rhinocypha) cuneata, another Data Deficient species, Epiophlebia laidlawi a Near Threatened species and Anisopleura bella a recently described species currently recorded only from Bhutan.

  • Title
    Species diversity and spatial distribution of snakes in Jigme Dorji National Park and adjoining areas, western Bhutan
    Type
    Journal Article
    Description
    This paper presents the results of a study conducted on the diversity and spatial distribution of snakes along the elevation gradients of Mochu River valley in Jigme Dorji National Park and its adjoining areas. The survey was conducted from July–September 2014 and May–July 2015. The study aimed to assess the diversity and distribution of snakes using opportunistic the visual encounter survey technique. A total of 17 species of snakes belonging to 15 genera and three families were documented during the study period. More than 53% of species were recorded in the lower sampling sites (between 1,200–500 m) indicating more favourable climatic conditions and habitat types for snakes assemblages at lower elevations indicating the importance of protecting low land forest areas for the conservation of snakes in the Bhutanese mountain ecosystem.

  • Title
    Gastropods in Bhutan, The genus Rahula (Pulmonata: Helicarionidae)
    Type
    Journal Article
    Description
    Two species of the poorly known genus Rahula are described as new to science from Bhutan. These species bridge the distributional gap that hitherto existed between Sikkim in the west and Arunachal Pradesh in the east. Additionally the taxa that are considered Rahula species in the literature are listed. On the basis of these data, the fragmentary distribution of the genus, from the E Himalaya southwards to Vietnam, Indonesia and Malaysia, is summarized.
