A recent study on the mosses of Meghalaya has revealed the occurrence of 6 taxa of the genus Entodon viz., E. concinnus (De Not.) Par. ssp. caliginosus (Mitt.) Mizushima, E. rubicundus (Mitt.) Jaeg., E. luridus (Griff.) Jaeg., E. plicatus C. Muell., E. scariosus Ren. & Card. and E. pulchellus (Griff.) Jaeg., out of which E. concinnus (De Not.) Par. ssp. caliginosus (Mitt.) Mizushima is a new addition to eastern Himalaya and E. scariosus is a new record to Meghalaya. Present paper provides the current status and morpho-taxonomic details of above mentioned species of Entodon in Meghalaya.

The original description of Parandricus mairei Kieffer, 1906 included a misinterpretation of a relevant forewing trait. The species was subsequently transferred to the genus Andricus, despite presenting two very peculiar morphological characters, namely a simple tarsal claw and the absence of irradiating carinae on the lower face. Similarly, the original descriptions of Andricus deqingis Wang, Gui, Chen, 2013 and A. flavus Pujade-Villar, Wang, Guo & Chen, 2014 included some relevant mistakes. Here, we present the results of a molecular analysis that reveals that individuals of the three species are genetically very similar; supporting the proposal that A. mairei is a senior synonym of the other two species, A. deqingis n. syn. and A. flavus n. syn. In addition, our results indicate that Parandricus renders Andricus paraphyletic, which supports that Parandricus is a junior synonym of Andricus. We re-describe and illustrate the relevant characters of A. mairei and provide additional comments on the characters erroneously interpreted in the former descriptions and give notes about the biology and intraspecific variability.

A region-specific species checklist is an important resource for biodiversity documentation and conservation. This review provides an updated mammal species checklist for the biodiversity hotspots of the Darjeeling-Sikkim landscape in Eastern Himalaya. The list was compiled by systematically reviewing 94 available publications spanning 178 years from 1841 to 2019, for mammals from the region. The species checklist is envisioned to aid in understanding the current status of mammal records, historical distribution, ranked conservation status of mammals, and research gaps. A total of 173 mammal species under 11 orders and 33 families, including the recently upgraded taxon, Sikkim Pika Ochotona sikimaria was enlisted. There are 25 species included in the IUCN threatened categories, 58 species listed in the CITES Appendices, and 112 species included in the schedules of the Wildlife (Protection) Act, 1972 in India. Although mammals receive the maximum research attention in the landscape, small mammals and bats have rarely been subjected to systematic studies in recent years.

During study on the family Mniaceae in Darjeeling and its neighbouring areas, three genera and six species (Mnium lycopodioides, Orthomnion bryoides, Plagiomnium acutum, P. confertidens, P. rhynchophorum and P. succulentum) have been identified. Of these Plagiomnium acutum is reported here for the first time from eastern Himalaya. A detailed morpho-taxonomic account of these species with their current status and a key to all the taxa of family Mniaceae in Darjeeling is provided here.

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.

Solid state x-ray sensing systems have been used for many years in conjunction with scanning and transmission electron microscopes. Such systems conveniently provide users with elemental area maps and quantitative chemical analyses of samples. Improvements on these tools are currently sought in the following areas: sensitivity at longer and shorter x-ray wavelengths and minimization of noise-broadening of spectral lines. In this paper, we review basic limitations and recent advances in each of these areas. Throughout the review, we emphasize the systems nature of the problem. That is. limitations exist not only in the sensor elements but also in the preamplifier/amplifier chain and in the interfaces between these components.Solid state x-ray sensors usually function by way of incident photons creating electron-hole pairs in semiconductor material. This radiation-produced mobile charge is swept into external circuitry by electric fields in the semiconductor bulk.
