  • Title
    A sighting of Plastingia naga (de Nicéville, [1884]) (Lepidoptera: Hesperiidae: Hesperiinae) from central Assam, India
    Type
    Journal Article
    Description
    The species Plastingia naga, de Niceville 1884is a very rare butterfly, and it occurs widely from Assam to Myanmar, Malay Peninsula, Sumatra, Borneo and Philippines (Evans, 1932). Except India, recently this species was recorded from Singapore, Sumatra and Thailand.On 10 Oct 2014 around 10:00hr, a solitary individual of Plastingia naga was sighted in Panbari Reserve Forest, Central Assam. Apart from the fact that these records constitute existence of this species in North-East India, this is probably the first photographic record from North-East India.

  • Title
    Sallywalkerana, a replacement name for Walkerana Dahanukar et al. 2016 (Anura: Ranixalidae)
    Type
    Journal Article
    Description
    Dahanukar et al. (2016: pp. 9234) made available the genus name Walkerana (type species: Ixalus diplostictus Günther, 1876: 574, Pl. 63 fig. C) within family Ranixalidae for the monophyletic group with reduced webbing endemic to the Western Ghats of India south of Palghat gap. We were unaware that this name was preoccupied by Walkerana Otte and Perez-Gelabert in Otte 2009, in Insecta: Orthoptera: Gryllidae. As a result, a replacement name for this genus of frogs becomes necessary. Here we propose Sallywalkerana gen. nov. as the replacement name for Walkerana Dahanukar, Modak, Krutha, Nameer, Padhye & Molur, 2016.

  • Title
    Reappearance of the rare Shingle Urchin Colobocentrotus (Podophora) atratus (Camarodonta: Echinometridae) after eight decades from the rocky shore of Kodiyaghat (Port Blair), South Andaman Islands, India
    Type
    Journal Article
    Description
    The present work is aimed at facilitating conservation efforts of a rare species of sea urchin ( Colobocentrotus atratus) reported nearly eight decades after its initial description by Bell (1887) and later by Clarke (1925) from the coastal waters of south Andaman Islands. Recently, during a three years study (2011-14) on the macrobenthic epifauna along the south Andaman coast, five live specimens of C. atratuswere recorded from Kodiyaghat (11 031'532''N; 092 043'457'' E), south Andaman Islands. Available information shows that this species has reappeared in the south Andaman Islands seventy nine years after the citation by Sastry (1994) collected in the year 1935. The disappearance of this species from the literature in the intermittent years and a sparse population in coastal reaches of south Andaman Islands at present suggest that this species makes a candidate taxa for inclusion in the list of ‘endangered’ or ‘vulnerable’ Indian marine species following IUCN Red List criteria to Wild species.

  • Title
    Heavy metal distribution in mangrove sediment cores from selected sites along western coast of India
    Type
    Journal Article
    Description
    Sediment cores were collected from four different mangrove areas of northern Kerala and southern Karnataka, western coast of India. The cores were analysed for the concentration of five heavy metals (Pb, Ni, Zn, Cu Fe) using Atomic Absorption Spectrometry. The levels of heavy metals in the present study from all the four sediment cores were in the order Fe > Pb > Zn > Ni > Cu and the mean concentrations of each elements in different cores were comparable. According to Sediment Quality Guidelines (SQG), the mangrove sediments analysed here were moderately contaminated with Ni and heavily contaminated with Pb. The increased concentration of Ni and Pb in the sediments might be due to their atmospheric deposition or water discharge from different far away sources since the areas selected for study were not disturbed by direct anthropogenic impacts. Elevated levels of Fe which is considered to be a common phenomenon in mangrove sediments have also been found in the present study. Heavy metal levels in sediments showed statistically significant correlations with pH, calcium carbonate and organic matter. This suggests the influence of physico-chemical parameters on the adsorption, deposition and persistence of heavy metals in mangrove sediments. The heavy metal concentration and the pollution status of the mangroves of west coast, especially the areas selected in this work are less studied before. Hence the data provide from the present baseline study would be further helpful in remediation and management of mangrove ecosystem.

  • Title
    An update on the distribution pattern and endemicity of three lesser-known tree species in the Western Ghats, India
    Type
    Journal Article
    Description
    The present communication reports an update on the distribution of three endemic tree species of the Western Ghats-Sri Lanka biodiversity hotspot, namely, Atuna indica (Bedd.) Kosterm., Paracroton integrifolius (Airy Shaw) N.P.Balakr. & Chakrab. and Phaeanthus malabaricus Bedd. The discovery of these taxa in the Makutta Ghat of Kodagu District results in the extension of their northern range limits and further enriches the flora of Karnataka state by three more tree species. Within the Western Ghats, these taxa were previously recorded only from the states of Kerala and Tamil Nadu, while Paracroton integrifolius (Airy Shaw) N.P.Balakr. & Chakrab. has also been recorded from Sri Lanka. Nomenclature updates, detailed descriptions, conservation status and relevant notes on the habitat, phenology and distribution localization are supplied. Additionally, field photographs and scanned herbarium specimens are provided to facilitate easy identification of these taxa in the field.

    Type
    Journal Article
    Description
    We report a checklist of spiders based on a survey made from August 2013 to July 2014 in Gujarat University Campus, an urban area located in the middle of Ahmadabad City, Gujarat State. A total of 77 species of spiders belonging to 53 genera and 20 families of spiders were recorded from the study area represented by 31.74% of the total 63 families reported from India. Salticidae was found to be the most dominant family with 18 species from 14 genera. Guild structure analysis revealed six feeding guilds, namely stalkers, orb-web builders, space-web builders, ambushers, foliage hunters and ground runners. Stalkers and orb-web builders were the most dominant feeding guilds representing 28.58% and 20.78% respectively among all studied guilds. Species Eilica tikaderi (Platnick, 1976) is reported for the first time from Gujarat with additional description and detailed genitalic illustrations.
