Hemidactylus paucifasciatus (Squamata: Gekkonidae), a new species of large-bodied, tuberculate gecko from Northern Odisha, India.

A new Hemidactylus belonging to the H. prashadi group is described herein, based on a series of four specimens from the Chota Nagpur Plateau in northern Odisha. Hemidactylus paucifasciatus sp. nov. can be diagnosed from regional congeners by its large body size (SVL up to 117.7 mm), the number of dorsal tubercle rows at mid-body, three or four bands on the dorsum, the number of enlarged tubercles in paravertebral rows, the number of femoral pores and poreless scales separating the left and right series on the femoral-precloacal row in males, and the number of ventral scales across the belly at mid-body. A mitochondrial phylogeny demonstrates that the new species is nested within the H. triedrus complex of the northern clade within the H. prashadi group, with 16.2-16.5 % pairwise divergence in ND2 sequence data from members of the H. triedrus complex and > 21 % from other members of the prashadi group. Hemidactylus paucifasciatus sp. nov. is the first endemic gecko to be described from the Chota Nagpur Plateau.

King or royal family? Testing for species boundaries in the King Cobra, Ophiophagus hannah (Cantor, 1836), using morphology and multilocus DNA analyses.

In widespread species, the diverse ecological conditions in which the populations occur, and the presence of many potential geographical barriers through their range are expected to have created ample opportunities for the evolution of distinct, often cryptic lineages. In this work, we tested for species boundaries in one such widespread species, the king cobra, Ophiophagus hannah (Cantor, 1836), a largely tropical elapid snake distributed across the Oriental realm. Based on extensive geographical sampling across most of the range of the species, we initially tested for candidate species (CS) using Maximum-Likelihood analysis of mitochondrial genes. We then tested the resulting CS using both morphological data and sequences of three single-copy nuclear genes. We used snapclust to determine the optimal number of clusters in the nuclear dataset, and Bayesian Phylogenetics and Phylogeography (BPP) to test for likely species status. We used non-metric multidimensional scaling (nMDS) analysis for discerning morphological separation. We recovered four independently evolving, geographically separated lineages that we consider Confirmed Candidate Species: (1) Western Ghats lineage; (2) Indo-Chinese lineage (3) Indo-Malayan lineage; (4) Luzon Island lineage, in the Philippine Archipelago. We discuss patterns of lineage divergence, particularly in the context of low morphological divergence, and the conservation implications of recognizing several endemic king cobra lineages.

A novel, diminutive Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) from a sacred grove in Odisha, eastern India.

We describe a distinct new species of Hemiphyllodactylus from a sacred grove near Humma in Ganjam District of Odisha state, eastern India. Hemiphyllodactylus minimus sp. nov. is the smallest member of the genus and can be diagnosed from all peninsular Indian congeners by its small body size (SVL ≤32.2 mm, n=11), having 15-18 dorsal scales and eight or nine ventral scales at mid-body contained within one longitudinal eye diameter, nine or ten precloacal pores separated by 4-6 poreless scales from a series of six or seven femoral pores on each thigh in males, lamellar formula of manus 2222 and of pes 2332 2333, as well as subtle colour pattern differences. Additionally, the new species is 16.0-22.7 % divergent from all other peninsular Indian Hemiphyllodactylus in uncorrected ND2 sequence data. The new species is the first member of the genus described from Odisha state and also the first Hemiphyllodactylus known from < 100 m asl. The discovery of Hemiphyllodactylus minimus sp. nov. from a low elevation coastal locality in the Eastern Ghats open ups the possibilities that the genus could be more widespread than currently understood and potentially harbour many more distinct undescribed lineages. Therefore, dedicated fine-scale sampling efforts are needed to uncover the true diversity and distribution of Hemiphyllodactylus in the region.

"Endangered or an artifact of unsound taxonomy? Case of the critically endangered bush frog Philautus sanctisilvaticus Das and Chanda, 1997".

We investigated the phylogenetic relationship of the Critically Endangered bush frog Philautus sanctisilvaticus Das and Chanda, 1997 and other species distributed across the fragmented forests of Deccan Peninsula and the northern Eastern Ghats. A short fragment of the mitochondrial 16S rRNA gene was employed to assess phylogenetic relationships across Philautus sanctisilvaticus Das and Chanda, 1997, Raorchestes terebrans (Das and Chanda, 1998) and Philautus similipalensis Dutta, 2003. All sequenced specimens, including material from near the type localities of P. sanctisilvaticus (Amarkantak) and P. similipalensis (Simlipal) were genetically extremely similar, with pairwise uncorrected distances 1% in the 16S gene, and were phylogenetically placed within the genus Raorchestes. The results based on morphology are ambiguous and do not go hand in hand with molecular data, which however do not provide support for a three species hypothesis either. our findings advocate the need for making nomenclatural amendments. Philautus sanctisilvaticus Das and Chanda, 1997, is the first available nomen for this taxon, and we propose to include this species in Raorchestes as Raorchestes sanctisilvaticus (Das and Chanda, 1997), and to consider the nomina Philautus terebrans Das and Chanda, 1998 syn. nov. and Philautus similipalensis Dutta, 2003 syn. nov. as junior subjective synonyms for this nomen following the Principle of Priority in article 23.1 of the ICZN. The findings are notable from the point of conservation of the species and present a novel case with remarkable genetic homogeneity across the fragmented forests of Deccan Peninsula and Eastern Ghats.

A new genus and species of arboreal toad with phytotelmonous larvae, from the Andaman Islands, India (Lissamphibia, Anura, Bufonidae).

A new bufonid amphibian, belonging to a new monotypic genus, is described from the Andaman Islands, in the Bay of Bengal, Republic of India, based on unique external morphological and skeletal characters which are compared with those of known Oriental and other relevant bufonid genera. Blythophryne gen. n. is distinguished from other bufonid genera by its small adult size (mean SVL 24.02 mm), the presence of six presacral vertebrae, an absence of coccygeal expansions, presence of an elongated pair of parotoid glands, expanded discs at digit tips and phytotelmonous tadpoles that lack oral denticles. The taxonomic and phylogenetic position of the new taxon (that we named as Blythophryne beryet gen. et sp. n.) was ascertained by comparing its 12S and 16S partial genes with those of Oriental and other relevant bufonid lineages. Resulting molecular phylogeny supports the erection of a novel monotypic genus for this lineage from the Andaman Islands of India.

Hematology and plasma biochemistry of wild-caught Indian cobra Naja naja (Linnaeus, 1758).

BACKGROUND: Hematology and plasma biochemistry parameters are useful in the assessment and management of snake physiological status. Although reference ranges are readily available for many snake species, they are lacking for most venomous ophidians. We determined hematology and plasma biochemistry reference ranges for the wild-caught Indian cobra, Naja naja. RESULTS: Blood samples, taken from the ventral tail vein, were assessed for erythrocyte count, total leukocyte count, hemoglobin concentration, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration, considering the sex of snakes. Results revealed the erythrocyte numbers (male, 390000 ± 12503.33/mm(3) and female, 347500 ± 7505.55/mm(3)), shapes and the centrally located oval nuclei. Leukocytes were round, circular or disk-shaped, and the mean size was larger in male than female snakes. The maximum number of leukocytes was found to be 11700 ± 100/mm(3) in male and 12100 ± 200/mm(3) in female snakes, and mean values of differential leukocyte count differed statistically between male and female snakes. The total leukocyte levels were found to be higher in female snakes, but the levels of hemoglobin, hematocrit, and MCV values were higher in male snakes. However, the MCH and MCHC values remained higher in female snakes throughout the study period. Mean protein and cholesterol contents differed significantly between male (45.32 ± 1.76 and 3.76 ± 0.06 mg/mL) and female (12.47 ± 0.82 and 4.72 ± 0.2 mg/mL) snakes. CONCLUSIONS: In conclusion, monitoring snake hematological and biochemical parameters can serve as a means to evaluate the physiological and health status of N. naja populations, which may be a useful indicator of their environmental status.

The first teresomatan caecilian (Amphibia: Gymnophiona) from the Eastern Ghats of India--a new species of Gegeneophis Peters, 1880.

A new species of caecilian amphibian, Gegeneophis orientalis sp. nov., is described based on a series of nine specimens from high elevation (ca. 1,200 m) habitats in the Eastern Ghats in the states of Andhra Pradesh and Odisha, India. This species differs from all other congeners in having only bicuspid teeth in the outer as well as inner rows. The new species is the first caecilian reported from the state of Odisha, the first teresomatan caecilian from the Eastern Ghats, and is the only Indian indotyphlid known from outside the Western Ghats region.

A new species of Duttaphrynus (Anura:Bufonidae) from Northeast India.

A new species of montane toad Duttaphrynus is described from Nagaland state of Northeast India. The new species is diagnosable based on following combination of characters: absence of preorbital, postorbital and orbitotympanic ridges, elongated and broad parotid gland, first finger longer than second and presence of a mid-dorsal line. The tympanum is hidden under a skin fold (in male) or absent (in female). The species is compared with its congers from India and Indo-China. We propose to consider Duttaphrynus wokhaensis as junior synonym of Duttaphrynus melanostictus.

In Vitro Antibacterial and Antioxidant Studies of Croton roxburghii L., from Similipal Biosphere Reserve.

In vitro antibacterial activities of acetone, ethanol, methanol and water extracts of leaves and bark of Croton roxburghii L. studied against ten human pathogenic bacterial strains showed significantly higher activity in acetone extract and least activity in case of aqueous. Minimal inhibitory concentration (MIC) values of all extracts ranged between 0.62 and 10 mg/ml, while minimal bactericidal concentration (MBC) values ranged from 1.25 to values greater than 10 mg/ml. The antioxidant assays viz. DPPH, hydrogen peroxide scavenging, iron reducing and iron chelating assays along with total phenol and ascorbic acid content were carried out with aqueous extracts of leaves and bark. While the total phenol contents in leaves and bark extracts were 0.766 ± 0.014 and 0.735 ± 0.028% respectively their ascorbic acid contents were found to be 0.252 ± 0.019 and 0.431 ± 0.013% respectively. DPPH activities in both (leaves and bark) extracts increased with the increase in concentrations. Iron chelating capacity of leaves extract is significantly higher than that of the bark. Leaves extract showed an increase in percentage of scavenging property with the increase in concentrations. Plant extracts showed low amount of iron reducing property at all concentrations. Hydrogen peroxide scavenging properties of bark was low than that of the leaves.

Histology of vitamin A induced ectopic limbs and normal hind limbs in tadpoles of Polypedates maculatus.

Marked histological similarities were observed between normal and vitamin A induced ectopic limb buds of P. maculatus. However, close association of nephric tubule and lateral plate mesoderm, as seen in normal hind limb bud does not seem to be essential for ectopic limb development. The ectopic limbs tend to develop in pairs.
