Abstract Pythonidae, an ancient group of Old World, wide-ranging, constrictor snakes, are known to contain a high degree of cryptic diversity. India harbours three python species, Python molurus, P. bivittatus, and Malayopython reticulatus. The former two species are not uncommon within their respective distribution range in India, but occurrence of the latter has only been confirmed in the Nicobar Islands, and there are two orphaned records from eastern West Bengal. We confirm the occurrence of P. bivittatus and M. reticulatus in Northeast India based on genetics using the mitochondrial cytochrome b gene and morphological characters. Our study reveals multiple lineages among M. reticulatus, corroborating previous studies, and further reveals the absence of a barcode gap between sequences submitted as P. molurus and P. bivittatus among the sampled DNA sequences, and an unexpected lineage of Northeast Indian P. bivittatus based on a sample divergent from the East and Southeast Asian populations that will need further systematic assessment.

A FURTHER TAXONOMIC REASSESSMENT OF Cyrtodactylus madarensis SHARMA, 1980 (SQUAMATA: GEKKONIDAE) NOW IN THE GENUS Eublephairs Gray, 1827 (SQUAMATA: EUBLEPHARIADE)

Abstract A recent phylogenetic study identified the population of Eublepharis Gray, 1827, from Rajasthan (India) as a distinct taxon from Eublepharis macularius (Blyth, 1854). A taxonomic reassessment of the population based on literature, existing museum material and molecular data allowed me to assign the name Eublepharis madarensis (Sharma, 1980) to this population. A redescription and rediagnosis of the species are presented based on museum material and images of uncollected individuals. A discussion on the assignment of the nomen ‘madarensis’ is presented. The species appears to be distributed along the Aravalli hills, and most records of the species lie outside of protected areas.

Abstract The montane agamid lizard Japalura austeniana (Annandale, 1908), is rare and is distributed across parts of the eastern Himalayas of India and China. Support from molecular and morphological data provide evidence for the existence of a species complex in the populations referred to as that binomen, and we here describe a morphologically cryptic allied new species. Evidence from molecular data suggests the presence of additional undescribed species across the distribution of that species complex. Elevation might be the restricting factor for gene flow explaining most of the diversification of that montane species complex across the Himalayas.

The Western Ghats of India is known across the world as a biodiversity hotspot due to its rich plant and animal diversity. Orchids are most abundant in this humid tropical and subtropical region. India has 1331 orchid species distributed over 186 genera, of which 400 are endemic. Many orchid species have been reported from Mulshi (alt. 600–1,131 m a.s.l.) which falls in the Northern Western Ghats of Maharashtra. Recently, Jalal & Jayanthi (2018, 2019) recorded 32 genera and 107 species of orchids from the northern Western Ghats. The vegetation is diverse from moist to dry deciduous forests with some semi evergreen elements and open grasslands.
Strobilanthes Blume consists of approximately 350 species, chiefly distributed in the tropical and sub-tropical parts of Asia but extending to the Pacific islands. Approximately 150 species of Strobilanthes are reported from India and, among them, around 70 species are restricted to South India. In the course of a floristic survey in the Megamalai Hills of Tamilnadu in 2016–2017, we collected a remarkable specimen of Strobilanthes, which was characterized by having viscous uninterrupted spikes with a subventricose corolla. Since it has spicate inflorescences, 5-partite calyces, two fertile stamens, and densely hygroscopic-pubescent seeds, the material belongs to the S. kunthiana group. After a critical examination of relevant literature and herbarium materials it was found that the specimen matches the type of S. humilis, hence our collections are the first verified collection after its type collections in 1836.
