An opportunistic mating attempt of a flower crab spider (Thomisus sp.), India

Flower crab spiders of the genus Thomisus, Walckenaer, 1805 have a crab-like habitus with its first two pairs of legs that are long and robust. The Thomisus spiders do not build webs, but instead capture their prey using ambush, or sometimes by active pursuit hiding in flowers, leaves, and leaf litter. Some species flatten their bodies to hunt inside crevices or tree trunks under loose bark. Most of the Thomisus species are sexually dimorphic, males are much smaller than females. On 2 November 2020, I observed a female crab spider capturing a chestnut bob butterfly (Lambrix salsala) while it was trying to feed on the nectar of Jamaican spike flowers, Stachytarpheta jamaicensis (Verbenaceae) in the Butterfly Garden located at Sanjay Gandhi National Park (SGNP), Maharashtra, India.
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.
