The tribes Contradentini and Rectidentini (Unionidae) comprise a diverse clade of freshwater mussels endemic to South-east Asia. Our understanding of the diversity and phylogeny of this radiation has improved dramatically in recent years, but this systematic transformation has not yet benefited from comprehensive museum sampling or phylogenomic methods. A synthetic taxonomic revision of the Contradentini+Rectidentini that leverages these useful and accessible methods is needed. We set out to (1) generate a phylogenomic reconstruction of the supraspecific relationships of the Contradentini+Rectidentini using anchored hybrid enrichment, (2) revise the taxonomy and geographic boundaries of the generic and species-level diversity of the radiation, and (3) identify patterns of freshwater mussel diversity and distribution in this clade and discuss the processes that may have precipitated them. Our phylogenomic reconstruction using over 1600 loci, with a total alignment length of over a half a million nucleotides, recovers a well supported phylogeny of the clade that resolves four independent multispecies radiations endemic to the Mekong drainage. We examined, digitised, and imaged 1837 records from 15 natural history museums that provided the necessary data to document the morphological variation and geographic distributions of the focal taxa. We also analysed 860 COI sequences, 519 of which were generated in this study, to better understand the species boundaries and geographic distributions of the recovered clades. We recognise 54 valid species in the tribes Contradentini and Rectidentini, including 9 described herein as new to science. Out of this revision emerged several interesting biogeographic patterns that appear to have resulted from recent stream capture, historical confluence, and intradrainage barriers to dispersal. We hypothesise that these phenomena shaped the diversity and distribution of the Contradentini+Rectidentini, contributing to the formation of several characteristic freshwater mussel provinces in South-east Asia.

Since early 2000 years, the knowledge about the taxonomy of Aloninae (Cladocera: Chydoridae) has been in rapid progress. For this reason, the most of Brazilian fauna was affected concerning nomenclature, besides an increase in the number of known genera and species. Thus, in this study, we bring an updated species list of Aloninae in Brazil, as well as identification keys based in current nomenclature and morphological standards. Our finding pointed to the occurrence of 46 valid species, belonging to 21 genera and three groups of Alona sensu lato. Two of these genera are endemic to Brazil. So far, South-East Asia and Brazil have the most well-studied Aloninae fauna in the entire planet.

AbstractA group of externally very similar, grey species of the genus Nemophora Hoffmannsegg, whose females possess a brush of dark scales at the middle of their antenna, is revised. Five species of this group, all distributed in South-East Asia, are recognized: N. griseella (Walsingham) sp. rev. [= cyphozona (Meyrick) syn. n. ; = tricrates (Meyrick) syn. n.] from India, Burma and Nepal; N. ichnodesma (Meyrick) comb. n. from India and W Malaysia; N. cassiterites (Meyrick) comb. n. from India only; N. askoldella (Millière) [= irroratella (Christoph) ; = niphites (Meyrick) syn. n.] from China, S Korea, Japan, Khabarovsk and Primorye regions of Russia; N. chionites (Meyrick) comb. n. from India and Thailand. Data on all primary types are provided; lectotypes are designated where necessary. The monophyly of the group and the relationships of its species are discussed. Keys to species based on external characters and male genitalia are provided; adults and male genitalia are described and illustrated.

Distinct Genus

Ochralea was described by Clark in 1865 for a very large Oriental galerucine with elongate basal metatarsomeres. Subsequently, nigh more species were described in this genus. It was synonymised with Monolepta by Weise in the Catalogue to the Galerucinae in 1924, and accepted as such by most subsequent authors. Whilst revising the type species of Monolepta, M. bioculata (Fabricius, 1781), it became clear that Ochralea was a distinct genus. The revalidation and redescription of this genus, containing two valid species, is here proposed. Ochralea nigripes (Olivier, 1808) has one recognised junior synonym and Ochralea nigricornis Clark, 1865, and two new synonyms Ochralea pectoralis Harold, 1880 syn. nov. and Monolepta erythromelas Weise, 1922 syn. nov. This species is abundant and widely distributed in south-east Asia from Bengalia and Bangladesh to southern China, the Philippines and Sulawesi. Ochralea wangkliana (Mohamedsaid, 2005) comb. nov., is only known from a few specimens collected around Wang Kelian Perlis, Malaysia. Redescriptions of the genus and the two species are given, including illustrations of external and genital characters, and a distribution map.

Species Descriptions

Mezoneuron is a genus of 24 species that has often formerly been understood to belong within Caesalpinia s.l., but which on the basis of recent molecular evidence, along with a number of other segregates, is now considered a distinct genus. Mezoneuron is broadly distributed, with its centre of diversity in South East Asia, but with species also in Africa, Australasia, and Hawaii. This is the first study to conduct a complete revision of the genus across its geographical range. A key to the species is provided, along with full species descriptions, distribution maps, preliminary conservation assessments, and selected illustrations. This study examines the morphological evidence supporting the generic status of the group, particularly of the fruit type, which has traditionally been considered its defining feature.

To determine the immunization status of pediatric patients under age of 5 years visiting pediatric department of tertiary care hospitals in South East Asia. The aim of this study was to appreciate the awareness and implementation of vaccination in pediatric patients who came into pediatric outpatient Department with presenting complain other than routine vaccination. we can also know the count of patients who do not complete their vaccination after birth. we can differentiate between vaccinated and unvaccinated patients and incidence of severe disease in both groups. Immunization is a protective process which makes a person resistant to the harmful diseases prevailing in the community, typically by vaccine administration either orally or intravenously. It is proven for controlling and eliminating many threatening diseases from the community. WHO report that licensed vaccines are available for the prevention of many infectious diseases. After the implementation of effective immunization the rate of many infectious diseases have declined in many countries of the world. South-East Asia is far behind in the immunization coverage. An estimated total coverage is 56%-88% for a fully immunized child, which is variable between countries. Also the coverage is highest for BCG and lowest for Polio.

It had long been believed that none of the bird, egg or nest specimens that had been in the collection of Sir Hans Sloane at his death in 1753 had survived. However, a specimen of a rhinoceros hornbill, originally in Sloane's hands, was discovered in the Natural History Museum's collections in London in 2003, and three more Sloane hornbill specimens have subsequently come to light. In addition, we report here a most unexpected discovery, that of the head of a woodpecker among the pages of one of Sloane's bound volumes of pressed plants. The context suggests that the head, like its associated plant specimens, was probably collected in south-east Asia about 1698–1699 by Nathanael Maidstone, an East India Company trader, the material reaching Sloane via William Courten after the latter's death in 1702. A detailed description of the head is provided, along with observations on its identity and possible provenance.
