Clytoctantes alixii is a bird that lives on the edges of old-growth, secondary and cleared forests undergoing regeneration and presents a distribution restricted to Colombia and Venezuela. The species is considered to be at risk of extinction (EN) due to its particular characteristics and restricted distribution. However, knowledge of its ecology and distribution is still incipient. The objective of this study was therefore to expand the knowledge of C. alixii in Caldas, present the southernmost record of the species and describe its behaviour. The species was monitored within the protected areas of the Manso Diversion in the period 2014 and 2017, using mist nets and fixed radius point counts. Two individuals of C. alixii were recorded, both by observation, with one of these subsequently also captured in a forest in an advanced state of succession. Recording of this population is important because it is the southernmost in the Cordillera Central and confirms that habitats with the presence of hollow stem plants largely define the presence of the species, as well as potentially determining the location of other populations of this species within its range of distribution.

The present communication consists of the first ever catalogue of Indian Notodontidae Stephens, 1829 comprising systematic accounts of 242 species (including nominotypical subspecies) and 10 subspecies under 116 genera of 10 subfamilies with four new records to India viz. Phalera (Phalera) birmicola Bryk, 1949, Spatalina desiccata stolida Schintlmeister, 2007, Hiradonta hannemanni Schintlmeister, 1989 and Kamalia tattakana (Matsumura, 1927). The account was prepared by compiling findings from both literature survey and field sampling carried out at various Protected Areas in the Indian Himalayas and Chhattisgarh state in the Deccan Peninsular region of India. Zoogeographic analysis of Indian Notodontidae reveals a majority of the assemblage showing Oriental (58.27%) and Palaearctic (40.49%) affinities with maximum species of Sundanian (80.00%), followed by Himalayan (77.65%) origins. In India, the majority of the species are distributed in the Himalayan (35.33%) and North-East (39.40%) biogeographic zones, reflecting maximum endemicity. Extensive surveys in the less explored southern part of the country are expected to enrich the inventory of Indian Notodontidae. The distribution map and detailed illustrations of the four new records are provided.

The northern part of the Cordillera Central in Colombia has been recognized as a region of particular relevancy in vertebrates biodiversity. We provide a list of non-volant mammal species in Jaguas and San Carlos, two protected areas around hydroelectric projects on the eastern slope of the Cordillera Central in Antioquia. As part of an ongoing monitoring project, we obtained records from a standardized survey in 2011 and sporadic surveys in 2014–2015 (capture and non-invasive methods), and from the revision of voucher specimens. From 132 records we generated a list of 34 species, 22 species in Jaguas and 27 in San Carlos, belonging to 20 families and seven orders. We record the occurrence of four endemic and four threatened species, including the endemic and Endangered Tamarin, Saguinus leucopus, highlighting the importance of these protected areas for mammal conservation in this highly diverse region.

Threatened species lists are used at global, national and regional scales to identify species at risk of extinction. Many species are listed due to restricted population size or geographic distribution, and decline is often inferred rather than quantified. Vascular plants comprise over 70% of nationally listed threatened species, but there is an incomplete picture of which species are most at risk of extinction, where these occur and the factors behind their declines. We compiled published information and the best available field knowledge including 125 expert interviews to identify declining and at risk species. The candidate list comprised 1135 taxa, which were mostly listed as Critically Endangered or Endangered under Federal and/or State legislation, but included 80 that are currently unlisted but considered to be highly threatened. In total, 418 taxa were assessed as having a documented, suspected or projected continuing decline. These were ranked based on extinction risk and magnitude of continuing decline, which suggest that 296 are at risk of extinction under current management regimes, including 55 at high risk of extinction. Declining and imperilled taxa are concentrated in a relatively small number of regions and habitats, and six threatening processes are driving the majority of declines. Field surveys and robust, repeatable monitoring are required to better inform population trends and extinction risk, as well as inform the status of almost 200 taxa that are potentially imperilled but poorly known. Identification of declining taxa can identify key issues for flora conservation across a continent, and allow for targeted and efficient recovery efforts.

We provide a list of amphibian and squamate species collected in the Raso da Catarina Ecological Station, Bahia state, Brazil, during two distinct periods. An initial visual inventory of amphibians was conducted monthly from March 2010 to February 2011, using transects in a forest and temporary ponds. The second inventory was conducted over a 30-day period between March and April, 2012, when 37 pitfall trap arrays, each consisting of four buckets and supplementary glue traps, were set in low scrub and forest, complemented by opportunistic searches. A total of 19 lizard species, two amphisbaenians, 21 frogs, and 11 snakes were recorded during the study. New records for the protected area include 10 lizards, one amphisbaenian, 15 amphibians, and 11 snakes (36 species in total). Several species typical of the Atlantic Forest were collected, reflecting the potential influence of this biome, especially in the sampled forest habitats (Mata da Pororoca).

Among other activities, the South African National Survey of Arachnida (SANSA) aims to survey the biodiversity of arachnids in protected areas of South Africa. The study presented here documents the diversity of spiders and scorpions collected from the Nylsvley Nature Reserve (NNR), South Africa over a 30-year period. The spider fauna of NNR contains 175 species (7.5% of the total recorded in South Africa), in 131 genera and 37 families. Thomisidae is the most diverse spider family in the reserve, with 33 species (18.9% of the total), followed by Salticidae, with 20 species (11.4%), and Araneidae, with 18 species (10.3%). The majority of species (125) are wandering spiders (71.4%), whereas 50 species (28.6%) build webs. Wandering grounddwelling spiders comprise 52 species, whereas 73 wandering species have been collected from the vegetation. A total of 158 species are new records for the reserve and Oxyopes tuberculatus Lessert, 1915 is newly recorded for South Africa. Six spider species may be new to science. The scorpion fauna of NNR comprises five species (5% of the total recorded in South Africa) in three genera and two families. Buthidae are more diverse in the reserve, with four species and two genera represented. The scorpion fauna of the reserve includes two fossorial and three epigeic species, representing five ecomorphotypes: semi-zpsammophilous, pelophilous, lithophilous, corticolous and lapidicolous. Five additional scorpion species may be recorded if the reserve is sampled more intensively using appropriate techniques.
