Paraindopamphantus gen. nov., containing one species, I. bruneiensis sp. nov., is reported from Brunei, as the first member of the subfamily Pamphantinae from South East Asia and the second from the Oriental Region. The strikingly myrmecomorphic P. bruneiensis, collected only from Bukit Sulang, nr Lamunin in Brunei in the canopy of Shorea johorensis Foxw. (Dipterocarpaceae) tree by insecticide fogging is described and illustrated. The genus is placed in tribe Indopamphantini, that at present contains only other genus Indopamphantus Malipatil recorded from the Western Ghats of India. The significance of the habitus and myrmecomorphy of this species, in relation to Indopamphantus makutaensis Malipatil, is discussed. A key to the two genera of Indopamphantini is provided.

AbstractGondwana break-up is one of the key sculptors of the global biogeographic pattern including Indian subcontinent. Myrtaceae, a Gondwana family, demonstrates a high diversity across Indian Western Ghats. A rich paleo-records in Deccan Intertrappean bed in India strive to reconcile two contending hypothesis of origin and diversification of Myrtaceae in India, namely Gondwana elements floated on peninsular India or lineages invading from south-east Asia. In this study, we have reconstructed the biogeographic history of Myrtaceae of Western Ghats of India combining fossil-calibrated phylogeny, ancestral area reconstruction, and comparing various dispersal models.Phylogenetic reconstructions divided lineages into multiple clades at the tribal level that mostly is in agreement with previous descriptions. Dated tree indicated a presumable Gondwanan origin of Myrtaceae (95.7 Ma). The Western Ghats taxa are relatively younger and seem to have arrived either through long-distance oceanic dispersal in middle Eocene (Rhodomyrtus tomentosa), and Miocene (Eugenia) or through major overland dispersals throughout Miocene (Syzygium). However, late Cretaceous fossilsin India lends support to the existence of proto-Myrtaceae on floating peninsular India. Taken together, we conclude that Myrtaceae lineages on the biotic ferry were perhaps extirpated by Deccan volcanism leaving a little or no trace of living Gondwanan link, while the Western Ghats was likely enriched by dispersed elements either from south-east Asia or from South America.

Critical Notes

Habenaria Willdenow (1805: 544) is a large genus represented by approximately 848 species making it by far the largest in subfamily Orchidoideae (Cribb 2001, Kurzweil 2009, Govaerts et al. 2014, Batista et al. 2011), with centres of diversity in Brazil, southern and central Africa, and East Asia (Kurzweil & Weber 1992). In India, it is represented by 72 species, of which 36 are endemic (Misra 2007).  About 45 species of Habenaria are known to occur in the Western Ghats of India, of which 21 species are endemic (Jalal & Jayanthi 2012). In Kerala, 26 species were reported so far with 17 endemic (Sasidharan 2013).

AbstractRainfall-induced landslide inventories can be compiled using remote sensing and topographical data, gathered using either traditional or semi-automatic supervised methods. In this study, we used the PlanetScope imagery and deep learning convolution neural networks (CNNs) to map the 2018 rainfall-induced landslides in the Kodagu district of Karnataka state in the Western Ghats of India. We used a fourfold cross-validation (CV) to select the training and testing data to remove any random results of the model. Topographic slope data was used as auxiliary information to increase the performance of the model. The resulting landslide inventory map, created using the slope data with the spectral information, reduces the false positives, which helps to distinguish the landslide areas from other similar features such as barren lands and riverbeds. However, while including the slope data did not increase the true positives, the overall accuracy was higher compared to using only spectral information to train the model. The mean accuracies of correctly classified landslide values were 65.5% when using only optical data, which increased to 78% with the use of slope data. The methodology presented in this research can be applied in other landslide-prone regions, and the results can be used to support hazard mitigation in landslide-prone regions.

Distribution and habitat associations of the Critically Endangered frog Walkerana phrynoderma (Anura: Ranixalidae), with an assessment of potential threats, abundance, and morphology. Little is known about Walkerana phrynoderma, a frog endemic to the Anamalai Hills of the Western Ghats of India. Baseline information (i.e., distribution, threats, habitat characteristics, activity patterns, and relative abundance) is provided for this species, with the aim of improving our understanding of the status of the species in the wild. Visual-encounter, transect, and time-activity budget surveys were conducted in and around the Anamalai Hills of the Western Ghats. The frog skin was swabbed to determine the presence/absence of Batrachochytrium dendrobatidis, and habitat and environmental characteristics were recorded at sites where W. phrynoderma was found. These data were compared with those of sites apparently lacking this species that had suitable habitat. Walkerana phrynoderma is restricted to evergreen forests between 1300 and 1700 m a.s.l. in the Anamalai Tiger Reserve and at Munnar; thus, its range was extended from the state of Tamil Nadu to the adjoining state of Kerala. Pesticide runoff and human disturbance are the most severe threats to the species; B. dendrobatidis was not detected. This nocturnal anuran prefers forest edges and is associated with well-shaded forest foors in cool areas near freshwater streams. Walkerana phrynoderma is rarely encountered whereas its congener, W. leptodactyla, is more common. The impact of anthropogenic disturbances, especially waste disposal and development of tourism infrastructure, should be evaluated. The land that is owned by the Forest Department peripheral to the protected areas could be designated as eco-sensitive sites to prevent changes in land use that could have an adverse effect on W. phrynoderma.
