Although the original description of Solanum polyphyllum Phil. was made in 1891, this species was not seen until it was re-discovered 128 years later in 2019 in the Atacama Desert. Fruits and seeds were previously unknown and a complete description is provided here. This species was not treated in the most recent monograph of Solanum sect. Regmandra, but it should be incorporated in this section due to its glabrous, sessile and entire leaves, which are decurrent onto the stem. Morphologically, S. polyphyllum is similar to S. paposanum, also of section Regmandra, but differs in the entire leaves (against margins with 4–5 acute lobes in S. paposanum) and glabrous leaves (moderately pubescent adaxially and velutinous abaxially in S. paposanum). The rediscovery of S. polyphyllum at a new locality at the same altitudinal belt as the type, re-affirms its restricted distribution and endemism and supports a potential conservation status as an endangered species.

Some of the taxonomic characters originally argued for the Cuban monotypic genus Cubacanthozomus Teruel, 2007, are unsubstantial. Others were misinterpretations of drawings given in the original description of Schizomus rowlandi Dumitresco, 1973, the only source of taxonomic information on which Teruel (2007) based the new genus. Recently a new collection of this species was made in a small cave about 350 m from one of the caves mentioned in the original description: Cueva de Majana, Baracoa municipality, Guantánamo province. On the basis of new morphological evidence found during examination of two females and a male, both the genus Cubacanthozomus and its type-species are herein redescribed. Cueva de Majana is recognized as the true type locality of C. rowlandi, which male holotype was erroneously listed as being collected in a cave from central Cuba, 600 km away. Additional data are provided on the morphology, natural history and conservation status of C. rowlandi, which is now being proposed as an endangered species.

Eugenia subamplexicaulis belongs to Eugenia sect. Pilothecium and was described based on a collection made in São Paulo state by C.F.P. von Martius in 1817. After that, no other collection of this species was made until May 2018, over 200 years later, when this species was rediscovered in the rocky formation Monumento Natural da Pedra de Itaocaia, a protected area located in Rio de Janeiro state. This study provides an enhanced morphological description of the species, notes on its morphological affinities, geographic distribution and conservation status. The species can be recognized by its subsessile leaves, dichasial inflorescences and oblate fruits with up to three seeds. The fruits are described for the first time, since the original description was based only on a single flowering specimen. Additionally, the first photographic documentation of the live plant in its habitat is presented.

AbstractThe co-extinction of parasitic taxa and their host species is considered a common phenomenon in the current global extinction crisis. However, information about the conservation status of parasitic taxa is scarce. We present a global list of co-extinct and critically co-endangered parasitic lice (Phthiraptera), based on published data on their host-specificity and their hosts’ conservation status according to the IUCN Red List. We list six co-extinct and 40 (possibly 41) critically co-endangered species. Additionally, we recognize 2–4 species that went extinct as a result of conservation efforts to save their hosts. Conservationists should consider preserving host-specific lice as part of their efforts to save species.

Avicularia diversipes (C. L. Koch 1842) known previously only from its original description is redescribed along with Avicularia sooretama sp. nov. and Avicularia gamba sp. nov. The three species are endemic to Brazilian Atlantic rainforest. With other Avicularia species, they share a procurved anterior eye row, slender embolus and medially folded spermathecae, whereas they have unusual characters, such as a very long and spiraled embolus (A. diversipes) and spermathecae with multilobular apex (A. sooretama sp. nov.). Furthermore, the three species lack a tibial apophysis in males and share a distinctive color pattern ontogeny that is not known in any other Avicularia species. The conservation status of the three species is discussed, especially with respect to endemism, illegal trafficking and habitat destruction. The creation of protected areas in southern State of Bahia, Brazil, is recommended, as well as the inclusion of these species in IUCN and CITES lists. Appendices with figures and species information are presented to facilitate correct specimen identification by custom officers, in order to limit illegal traffic.

The main objectives of the Nepal National Bird Red Data Book were to provide comprehensive and up-to-date accounts of all the bird species found in Nepal, assess their status applying the IUCN Guidelines at Regional Levels, identify threats to all bird species and recommend the most practical measures for their conservation.  It is hoped that the Bird RDB will help Nepal achieve the Convention on Biological Diversity target of preventing the extinction of known threatened species and improving their conservation status.  As population changes of Nepal’s birds have been studied for only a few species, assessments of species’ national status were mainly made by assessing changes in distribution.  Species distribution maps were produced for all of Nepal’s bird species except vagrants and compared to maps that were produced in 1991 using the same mapping system.  Of the 878 bird species recorded, 168 species (19%) were assessed as nationally threatened. These comprise 68 (40%) Critically Endangered species, 38 (23%) Endangered species and 62 (37%) Vulnerable species.  A total of 62 species was considered Near Threatened and 22 species Data Deficient.  Over 55% of the threatened birds are lowland grassland specialists, 25% are wetland birds and 24% tropical and sub-tropical broadleaved forest birds.  Larger birds appear to be more threatened than smaller birds with 98 (25%) non-passerine species threatened and 67 (14%) passerine species.  Habitat loss, degradation and fragmentation are the most important threats.  Other threats include chemical poisoning, over-exploitation, climate change, hydropower, invasive species, intensification of agriculture, disturbance, and limited conservation measures and research.  Measures to address these threats are described.  It was also concluded that re-assessments of the status of certain bird groups carried out every five years and the setting up of a national online system for storing and reporting bird sightings would be useful.

Background and Aims: Gustavia sessilis is a neotropical tree, belonging to the Lecythidaceae family, until now known from the Colombian Chocó region only. In this paper, we report G. sessilis for the first time for Central America. Methods: Central American specimens of G. sessilis were collected in 2019 from the Darién Province (eastern Panama). Plant identifications were confirmed by comparing collected specimens with those identified earlier and housed in the MO, PMA, SCZ and UCH herbaria. Type specimens were examined by consulting the JSTOR Global Plants database. The estimations of the conservation status were made based on the criteria of the IUCN.Key results: The record of G. sessilis for Central America is presented, based on a collection made from eastern Panama (Darién Province). Photographs, taxonomic comments, and conservation notes are provided. Additionally, a key for the Central American Gustavia species is included.Conclusions: The distribution of G. sessilis now ranges from Bahía Piñas, Darién Province, Panama to the Condoto river, Chocó region, Colombia, highlighting the importance of the Chocó Panama-Colombia region for the conservation of biodiversity, since it could act as a natural corridor for species. Taking into account the small number of records and the restricted natural range of this species, we recommend considering G. sessilis as an endangered species.
