  • Title
    Butterflies associated with major forest types in Arunachal Pradesh (eastern Himalaya), India: implications for ecotourism and conservation planning
    Type
    Journal Article
    Description
    A three year study (from December 2011 to December 2014 and in June 2015) on butterflies covering four major forest sub-types as classified by H.G. Champion & S.K. Seth in 1968 in ‘Forest Types of India’, which occupy 60% of the forest area lying below 2,500m across Arunachal Pradesh State in the eastern Himalaya of India, revealed 415 taxa belonging to six families (Hesperiidae: 74 species of 42 genera; Papilionidae: 37 species of 10 genera; Pieridae: 36 species of 15 genera; Lycaenidae: 85 species of 49 genera; Riodinidae: 7 species of 3 genera & Nymphalidae: 176 species of 71 genera, respectively). These included many endemic and rare species typical of these forest sub-types, i.e., (i) 2B/1S1 Sub-Himalayan Light Alluvial Semi-Evergreen Forest (32 species), (ii) 2B/ C1(a) Assam Alluvial Plains Semi-Evergreen Forests (5 species), (iii) 2B/2S2 Eastern Alluvial Secondary Semi-Evergreen Forests- (15 species) and (iv) 3/1S2 (b) Terminalia-Duabanga (3 species), respectively. The relative number of species and individuals sampled were the highest at altitudes below 500m, and gradually declined as the altitude increased to 2,000m, and above 2,500m species richness declined sharply. The number of species and their relative abundance were the highest during July–August (Monsoon-first peak) and then again in November-December (Autumn-second peak), while the numbers were lowest during winter. These findings suggest that these four forest types are important both for the purpose of ecotourism as well as conservation of endemic and rare taxa found in the eastern Himalaya and northeastern India at altitudes below 2,000m. A complete list of all the taxa sampled is given along with relative abundance status during sampling, Indian Wildlife (Protection) Act, 1972 status, and distribution in different forest types in the state. Ten potential butterfly ecotourism zones are suggested for the state. Planning land-use for biodiversity conservation based on butterfly-forest type associations, by taking forest sub-types as units of conservation, is suggested as an option for the eastern Himalaya.

  • Title
    New locality records of the ‘Dancing Girl’ of Mizoram, a rare zinger species
    Type
    Journal Article
    Description
    Mantisia spathulata (Roxb.) Schult. belonging to the family Zingiberaceae is a rare ornamental Zingiber distributed from eastern Himalaya to Myanmar. In India, this species is confined to very few localities of northeastern India. A new location for the species was discovered at Kolasib, Mizoram. The species was recorded growing at an altitude of 662m. A thorough ecological sampling was done for the population. Density of flowering individuals and non-flowering young individuals were estimated. The species has never been recorded at this altitude previously and, as per record, no ecological work has been done earlier. The average density of Mantisia spathulata within its growing patch is 18(±2) individuals per m2. A total of 120 juvenile individuals (without flowers) were recorded from a 1×1 m2 plot; indicating a very good regeneration of the species within the patch where it is growing.

    New records of Athyma whitei Tytler, 1940 (Lepidoptera: Nymphalidae: Limenitidinae) from northeastern India: a recently reported species from India
    Type
    Journal Article
    Description
    Tytler’s Sergeant, Atyma whitei was described by Tytler from Chin Hills, Myanmar in 1940. The taxon was not reported in India untill the record from Phura, Mizoram in November 2012. Recent surveys in northeastern India recorded the species four times in the forest of North Cachar (N.C.) Hills and E. Jaintia Hills. The new sightings are approximately 223km from Chin-type locality. These recent records of the rare insect gives an insight into the distribution range and habitat of the rare taxon in northeast India.

  • Title
    Dragonflies and damselflies (Insecta: Odonata) of Nagaland, with an addition to the Indian odonate fauna
    Type
    Journal Article
    Description
    We surveyed odonates in the districts of Kohima, Peren and Wokha in the state of Nagaland, northeastern India, during April and May 2012 and May 2013.  We recorded 69 species, including 43 additions to the known odonates of Nagaland, and one addition—Calicnemia erythromelas Selys, 1891—to the Indian odonate fauna. The known odonate fauna of Nagaland now consists of 90 species in 53 genera and 14 families.  We also describe for the first time the female of Coeliccia schmidti, and partially, a heterochromatic form of the female Ischnura mildredae.

  • Title
    Diagnosis and interrelationships of fishes of the genus Channa Scopoli (Teleostei: Channidae) of northeastern India
    Type
    Journal Article
    Description
    Diagnostic characters of nine species of the genus Channa Scopoli of northeastern India are given. Examination of morphological and osteological characters revealed that the fish under study comprised two phylectic groups: marulius and gachua. The Marulius group is characteristic by having a very prominent V-shaped sharp isthmus, cephalic sensory pores arranged in groups, absence of scales on the lower jaw, a sharp prominent spinelike hypurapophysis, more branchial toothplates than epibranchial, and an elongated urostyle. The Gachua group is characterized by a U-shaped isthmus, cephalic sensory pores evenly arranged in a single row, the presence of one or two large cycloid scales on each side of the lower jaw, absence of a sharp prominent spine-like hypurapophysis, absence or presence of one tooth plate in the epibranchial, and absence of an elongated urostyle. An elongated bone is present in between two last hemal spines of all species examined. A key to known species of Channa of northeastern India is also given

    First record of the catfish Gagata dolichonema He, 1996 (Siluriformes: Sisoridae) from India
    Type
    Journal Article
    Description
    Gagata dolichonema He, 1996 is recorded for the first time from the headwaters of the Chindwin drainage in Manipur, India. Mature individuals of this species are found to be sexually dimorphic. Males are distinguished by having long flexible distal tip of second dorsal spine extending well above the first branch ray. In females the spine terminates at the level of the first branch ray. Previous records of G. cenia from the Chindwin drainage are probably misidentifications of G. dolichonema.
