A reconnaissance survey was conducted in Southern Western Ghats, India to identify the wild populations of Terminalia paniculata. From the explorative survey, 16 natural populations from different localities of the study area were identified. Collected 36 fruits from each tree and fruit trait quantification of total 3456 fruits (36 x 16 x 6) from 16 populations were used for the study. Hierarchical clustering of selected populations and correlations among fruit traits and between tree traits and fruit traits visualised using a dendrogram. The results indicated significant differences in fruit traits like fruit fresh mass, fruit large wing length and fruit large wing width. Clustering of fruit characters for all the accessions revealed the genetic relatedness between accessions. It reveals that selected populations of T. paniculata belong to two major clusters and confirms that 16 populations are either adjacent or distant in-terms of fruit traits are independent of the geographical station. The relationship between fruit traits indicates a significant positive correlation between fruit traits ranging from 0.352 to 0.739. Even though fruit traits show significant correlation within, a non-significant and very week correlation was obtained with tree stand-up traits except tree girth with fruit large wing length (21.4 %).

A new subspecies, viz. Dimeria hohenackeri Hochst. ex Miq. subsp. kodaguensis Kiran Raj, Sivad. & Dileep from South Karnataka of the Southern Western Ghats in Peninsular India is described and illustrated. It mainly differs from D. hohenackeri Hochst. ex Miq. subsp. hohenackeri in having mat-forming habit with leaves crowded at culm-base, spikelets 3–4 mm long and glumes not widely divergent during anthesis.Bangladesh J.

A new butterfly taxon, Nacaduba sinhala ramaswamii ssp. nov. (Lepidoptera: Lycaenidae: Polyommatini), is described from Agasthyamalais of southern Western Ghats in peninsular India.  The new taxa can be diagnosed from all other Nacaduba of southern India and N. sinhala Ormiston, 1924  from Sri Lanka, by its distinct male genitalia.  The early stages, larval hostplants, flight periods, ecology and the known distribution of the new taxa are discussed.  The revised keys to all known Nacaduba of Western Ghats of peninsular India are provided.

We carried out a taxonomic revision of Ahaetulla species inhabiting Peninsular India, using a multiple criteria approach (including genetics, morphology, and geography). Our work included populations of the A. nasuta complex (widespread across the entire region, including the Western Ghats), the A. pulverulenta complex (in the Western Ghats, within Peninsular India) and the A. dispar complex (endemic to the Southern Western Ghats) which all revealed undocumented cryptic diversity. Here, we describe five new species and effect nomenclatural changes to some recognised taxa. In the A. nasuta complex, we describe four species from several latitudinal blocks of the Western Ghats and make nomenclatural emendations to the plains populations in the Indian peninsula. We effect nomenclatural change in the A. pulverulenta population of the Western Ghats and describe a new species from the A. dispar group. Our study highlights the use of a multi-criteria approach in unraveling cryptic diversity. This study also reveals a striking case of discordance between morphological and genetic divergence, and the way this is reflected in previous taxonomic and nomenclatural treatments of these populations.

Abstract Asian pit vipers belonging to the genus Craspedocephalus are a complex group of vipers, distributed in South and Southeast Asia. Their taxonomy is unresolved in many lineages across their distributional range. Here, we reassess the taxonomy and systematics of pit vipers of the genus Craspedocephalus in Peninsular India based on extensive field sampling, in particular in the Western Ghats. We build and expand on the previous findings of genetic relatedness between the peninsular Indian lineages with the Sundaic clade (C. puniceus complex) with greater evidence, based on additional taxa sequenced herein. We reconstruct the phylogeny of the group using three mitochondrial genes and delineated lineages using coalescent species delimitation methods. We then used multiple criteria including genetic divergence and separation in morphological and geographic space to designate taxonomic units. Our work revealed the presence of a South Asian radiation of the clade Craspedocephalus, with a few Sundaic members. Our study reveals the systematic relationships of four Peninsular Indian species of Craspedocephalus, including Peltopelor macrolepis and C. strigatus, sequenced here for the first time, that are classified or confirmed as members of Craspedocephalus. Hence, we place the genus Peltopelor in the synonymy of Craspedocephalus. Using our multi-criteria approach, we delimit four new cryptic evolutionary lineages within the Western Ghats escarpment of Peninsular India. These cryptic lineages belong to the C. malabaricus, C. gramineus and C. macrolepis complexes and are geographically and/or ecologically (in terms of habitat association) distinct from their sister lineages across their distributional range, while others are separated in morphological space. Our new phylogenetic tree and delimitation analysis thus reveals the presence of multiple clades with several cryptic lineages separated by geographical barriers or habitat association.

The present study observed that the family Elaeocarpaceae comprises three genera: Elaeocarpus, Sloanea and Muntingia in India. Of these, Elaeocarpus munronii, E. serratus, E. tectorius and E. tuberculatus were found infected with Asterina gamsii, A. elaeocarpi var. ovalis, A. elaeocarpicola and Asterostomella elaeocarpi-serrati in the Southern Western Ghats of peninsular India. All these species are described and illustrated in detail.

The monotypic genus Dravidogecko, represented by its type-species D. anamallensis, is singular amongst peninsular Indian gekkonid lineages in its endemism to the Western Ghats. Molecular species delimitation approaches reveal at least seven species-level lineages within the genus from its distribution range across the mid–high elevations of the southern Western Ghats of India. These lineages, albeit superficially cryptic, are patently diagnosable from each other by employing a limited but precise set of morphological characters. Six of these lineages that were obscured under the nomen D. anamallensis are herein recognized as distinct species. A reappraisal of the genus Dravidogecko is provided based on external morphology and osteological characters, along with a detailed redescription of the holotype of D. anamallensis. A key to the species based on diagnostic characters is presented. Gene-trees based on mitochondrial and nuclear DNA data recovered marginally disparate topologies and were consequently coalesced into a species-tree for phylogenetic inference. Timetree analysis reveals late Miocene cladogenesis in this group and establishes late Palaeocene divergence from its sister genus, Hemidactylus, making Dravidogecko one of the earliest, extant lizard lineages to have colonized peninsular India.
