We describe the tadpole of the Botsford’s leaf-litter frog Leptobrachella botsfordi, a species endemic to Mount Fansipan in northwest Vietnam, for the first time. Tadpoles of this species were found in steep, fast-flowing streams at elevations between 2500–2600 m asl. We also report a previously unknown locality for this species on Mount Fansipan, which increases the species’ known Extent of Occurrence from 8 km2 to 36 km2. Our findings will inform subsequent conservation initiatives for this poorly known and highly threatened species.

Vital Component

Information based on the accurate identification of species is a vital component for achieving successful outcomes of biodiversity conservation and management. It is difficult to manage species that are poorly known or that are misidentified with other similar species. This is particularly problematic for rare and threatened species. Species that are listed under endangered species classification schemes need to be identified accurately and categorised correctly so that conservation efforts are appropriately allocated. In Australia, the emballonurid Saccolaimus saccolaimus is currently listed as ‘Critically Endangered’. On the basis of new observations and existing museum specimens, we used a combination of genetic (mitochondrial DNA sequence) and morphological (pelage characteristics, dig III : phalanx I length ratio, inter-upper canine distance) analyses to identify six new geographic records for S. saccolaimus, comprising ~100 individuals. Our analyses also suggested that there are likely to be more records in museum collections misidentified as S. flaviventris specimens. The external morphological similarities to S. flaviventris were addressed and genetic, morphological and echolocation analyses were used in an attempt to provide diagnostic characters that can be used to readily identify the two species in the field. We recommend genetic testing of all museum specimens of Australian Saccolaimus to clarify species’ distributions and provide data for reassessing the conservation status for both S. saccolaimus and S. flaviventris. Museum curators, taxonomists and wildlife managers need to be aware of potential species misidentifications, both in the field and laboratory. Misidentifications that result in misclassification of both threatened and non-threatened species can have significant implications.

One of the main task of Cibodas Botanical Garden (CBG) is to conserve the Indonesian plants species. Moreover, the preservation and enrichment of threatened plant collections based on IUCN red list categories became an important programme for plants conservation in CBG. The aims of this study are to inventory threatened plant collections and to review the status of CBG threatened plant collections. List of threatened plant collections was gathered from SINDATA, a system developed by CBG. The collection, was reviewed by inspecting current collections in CBG. Literature study was done to review the conservation status of the threatened plant collections. The conservation status was checked in IUCN red list website. The results shown that CBG had collected 86 species of threatened plants, which is 13 Critically Endangered (CR) species, 39 Endangered (EN) species, and 34 Vulnerable (VU) species. Critically endangered category consists of 13 species belong to 8 families and 10 genus. Endangered category consists of 39 species belong to 17 families and 34 genus. Vulnerable category consists of 34 species belong to 27 families and 28 genus. The largest collections of threatened species was genus Nepenthes, which is 16% (14 species) from the total threatened species in CBG. Furthermore, CBG had succeeded in collecting 40 species of Indonesian native plants in which Dipterocarpaceae species were dominate the collection with 7 species. These species are listed as critically endangered (3 species) and endangered (4 species).

SummaryLaos is an important country for bird conservation. Bird surveys between 1992 and 1996, the first since 1949, covered 20 main areas, with incidental records from many others.This paper reviews the status of all Lao species reported to be of elevated conservation concern (key species) in any of the following categories: Globally Threatened or Globally Near-Threatened (sensu Collar and Andrew 1988 and Collar et al. 1994), and At Risk or Rare in Thailand (sensu Round 1988 and Treesucon and Round 1990). Several additional species are covered which have clearly undergone a National Historical Decline in Laos. A comprehensive review of other Lao species was not possible, and some species which are in truth of conservation concern have doubtless been overlooked. Historical and modern records were reviewed and population trends identified where possible.Current global status listings (Collar et al. 1994) were supported, except that consideration should be given to changing Red-collared Woodpecker Picus rabieri and Sooty Babbler Stachyris herberti from Threatened to Near-Threatened. If the Lao situation is representative of the species throughout their range, then consideration should also be given to placing Ratchet-tailed Treepie Temnurus temnurus and River Lapwing Vanellus duvaucelii as Near-Threatened.Twenty-seven Globally Threatened species are known from Laos, of which there are recent records of 22. There are recent unconfirmed records of two more. Forty-seven Globally Near-Threatened species are known from Laos, of which there are recent records of 39; there are unconfirmed records of one further species. Five Globally Threatened and five Near-Threatened species were recorded for the first time in Laos in recent years, suggesting that further species of elevated conservation concern remain to be found.

Freshwater fish fauna of Krishna River, Sangli district was studied from 2013 to 2017. A total of 73 species belonging to 10 orders, 22 families, and 49 genera were recorded, of which, 29 species are endemic to the Western Ghats and 11 species endemic to the Krishna River system. Labeo kontius, an endemic barb of the Cauvery River System was recorded for the first time from the Krishna River, Maharashtra. As per the IUCN Red List of Threatened Species, 54 species are assessed as ‘Least Concern’, four species as ‘Near Threatened’, three species as ‘Vulnerable’, five as ‘Endangered’, and two as ‘Data Deficient’. The conservation status of two species has not yet been assessed. Fish fauna of the Krishna River within the study area is threatened as a result of alien species, and several anthropogenic stressors such as pollution from industrial as well as agricultural sources, human settlements, and overfishing.  Since, this small study area harbours 28 endemic and eight threatened species, their conservation should be given high priority.

<em>Dionysia involucrata</em> Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of <em>D. involucrata</em> were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of <em>D. involucrata</em> according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of <em>D. involucrata</em> should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of <em>D. involucrata</em> have relatively high level of separateness due to different species composition. We define the new association – <em>Dionysietum involucratae</em> – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of <em>Dionysietum involucratae</em> were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, <em>Campanula incanescens</em>, <em>Carex koshewnikowii</em> and <em>Scutellaria hissarica</em> were the most abundant and frequent taxa within the researched patches of vegetation.

The Trigonidiinae crickets of Rodrigues are examined. Two species widespread in South Western Indian Ocean islandsare recorded in Rodrigues for the first time: Trigonidium cicindeloides Rambur, 1839 and Natula longipennis (Serville,1839). Nemobius luteolus Butler, 1876 is a Trigonidiinae and not a Nemobiinae, it is transferred to Metioche Stål, 1877 asMetioche luteolus (Butler, 1876), n. comb. Two new species are described from the restored areas of the island. Thesenew species are tentatively considered as Metioche and included in the new subgenus Superstes n. subgen.: Metioche (Su-perstes) superbus n. subgen., n. sp. and Metioche (Superstes) payendeei n. subgen., n. sp. This new subgenus is charac-terized by the male genitalia asymmetry and the striking hyperthely of the left pseudepiphallic lophi and paramere. Elements of the ecology of endemic Trigonidiinae of Rodrigues are given, and their conservation status is assessed.
