We compiled a checklist of the amphibians and reptiles of the state of Hidalgo, Mexico. The herpetofauna of Hidalgo consists of a total of 175 species: 54 amphibians (14 salamanders and 40 anurans); and 121 reptiles (one crocodile, five turtles, 36 lizards, 79 snakes). These taxa represent 32 families (12 amphibian families, 20 reptile families) and 87 genera (24 amphibian genera, 63 reptile genera). Two of these species are non-native species (Hemidactylus frenatus Duméril and Bibron, 1836 and Indotyphlops braminus (Daudin, 1803)). This herpetofauna represents a mixture of species from both the Sierra Madre Oriental and the Transvolcanic Belt. In addition, 26% of all categorized amphibian and reptile species in Hidalgo are considered Vulnerable, Near Threatened, Endangered, or Critically Endangered by the IUCN Red List. Thus, Hidalgo represents a relatively unique and threatened diversity of amphibians and reptiles.

We compiled an inventory of the amphibians and reptiles of the Cuautlapan Valley, Veracruz, Mexico based on field surveys and museum and literature records. We found a total of 78 species: 28 amphibians (6 Salamanders and 22 anurans); and 50 reptiles (three turtles, 18 lizards, and 29 snakes). These taxa represent 26 families (eight amphibian families, 18 reptile families) and 60 genera (19 amphibian genera, 41 reptile genera). Two of these species are not native to the area (Rhinoclemmys pulcherrima and Hemidactylus frenatus). According to the IUCN red list, five species are Critically Endangered, two are Endangered, four are Near Threatened, and four are Vulnerable. In the SEMARNAT (Secretaría del Medio Ambiente y Recursos Naturales) listing, one species is Endangered, eight species are Threatened, and 25 are Subject to Special Protection. Even though the Cuautlapan Valley is represented by a relatively small area it hosts a rich diversity of amphibian and reptile species, many of which are at risk and protected under Mexican law. This valley lies between the growing cities of Orizaba and Cordoba which have contributed to habitat degradation threatening the existence of the wildlife that occurs there.

AbstractThe Bermudian rock lizard or skink Eumeces longirostris is categorized as Critically Endangered on the 2000 IUCN Red List. Skinks are vulnerable to habitat loss, introduction of non-native species and mortality caused by discarded bottles and cans that act as selfbaiting traps. This study describes the population characteristics of the Bermudian skink on two islands of the Bermudian archipelago: Nonsuch and Southampton islands. Nonsuch Island is a nature reserve but has populations of introduced lizards of the genus Anolis, lizard-eating birds and (a new finding) the cane toad Bufo marinus. Southampton Island is relatively isolated and has no introduced species. The skink population on Nonsuch Island was not investigated in detail, but appears to be small, localized to human habitation (where cover and food scraps are available) and dominated by large, old (some possibly >27 years) animals that exhibit high mutilation rates. Breeding occurs, but survival to adulthood appears poor. All of neighbouring Southampton Island was intensively trapped, with traps placed at the intersections of a 10-m grid. The population was estimated by mark–recapture trials to be c. 400 adults and juveniles; hatchlings are insectivorous and not susceptible to trapping. The population on Southampton Island is currently the largest known on Bermuda and appears to be viable; sustained isolation from predators and people is essential to its maintenance.

The authors present a list of regionally extinct, threatened, lower risk and insufficiently status taxa of lichens in whole Poland. It is thirth edition of our list. Status of threat to the lichen species used has been determined according to the IUCN Red List Categories in version 3.1 (modified by GlNSBURG 2001). The Red List includes 886 taxa, which constitute 55.4% of the Polish lichen biota. The status of threatened biota has the following categories: Regionally Extinct (RE) - 141 taxa, Critically Endangered (CR) - 179, Endangered (EN) - 201, Vulnerable (VU) - 165, Near Threatened (NT) - 68, Least Concern (LC) - 22 and Data Deficient (DD) 110.

In this paper we present an updated checklist of mammals found in Meghalaya.  Using online databases and search engines for available literature, we provide the scientific names, accepted English names, conservation status as per IUCN Red List, Indian Wildlife (Protection) Act schedules, appendices in CITES, local distribution status, endemism, last reported sighting, an account of previous studies carried out relative to mammals and a tentative bibliography of the mammalian species found in Meghalaya.  A total of 162 species were found to be existing in the state with Chiropterans forming the largest group and 27 species found to be threatened, seven Near Threatened and seven Data Deficient.

The native species of amphibians and reptiles of Uruguay were categorized according to the IUCN Red List criteria. Out of 47 amphibian species, seven are listed as Critically Endangered (CR), five as Endangered (EN), one as Vulnerable (VU), three as Near Threatened (NT), and two as Data Deficient (DD); the remaining species are considered to be Least Concern (LC). Among the 64 species of reptiles evaluated, one is listed as Critically Endangered (CR), seven as Endangered (EN), two as Vulnerable (VU), one as Near Threatened (NT) and seven as Data Deficient (DD); the rest are considered to be Least Concern (LC). The use of these results as an additional criterion in the definition of protected areas in Uruguay will contribute towards the conservation of the aforementioned threatened species and their associated ecosystems.

The Leeward Blindsnake (Antillotyphlops geotomus) is a near threatened species according to the IUCN Red list (Powell et al., 2016), and was known only to occur on Antigua, Barbuda, St. Kitts, and Nevis, where it is considered a native species (Thomas 1966). Here we report the discovery of A. geotomus on St. Eustatius, Caribbean Netherlands. We obtained a DNA sequence of the mitochondrial 16S rRNA gene from a specimen collected on St. Eustatius in 2018 using the primers 16Sar (5’-CGCCTGTTTATCAAAAACAT-3’) and 16Sbr (5’-CCGGTCTGAACTCAGATCACGT-3’) (Palumbi 1996). The sequence was deposited in Genbank (MT256921). Blast analysis of the sequence resulted in 100% and 99.8% identity to sequences in Genbank of A. geotomus from Nevis (KF993199) and Antigua (AF366789) respectively. A 98.5% identity match was found with its nearest relative Antillotyphlops monastus (AF366708, KF993209). This species identification (A. geotomus) is consistent with the absence of pigment on the underside of the tail, a diagnostic trait of A. geotomus compared with A. monastus (Thomas 1966). The collected specimen had a total length of 125 mm, although they are known to reach lengths of up to 213 mm (Hedges et al. 2014). Furthermore, St. Eustatius is geographically in close proximity to St. Kitts & Nevis, which lie on the same shallow submarine bank only to be separated by the sea after the last ice age. Therefore, A. geotomus is likely native to St. Eustatius and not introduced. The other snake known from the island is the Red-bellied Racer (Alsophis rufiventris, native).

Drosera viridis Rivadavia, a Brazilian endemic species of carnivorous herb, has its geographical range extended in South Brazil, including the first records for Rio Grande do Sul, from subtropical highland grasslands in the northeastern region of the state. Taxonomic notes, habitat information, an updated distribution range, and an identification key for the Drosera L. species from Rio Grande do Sul are presented. Based on the updated distributional range and potential threats in Brazil, we suggest the species to be classified as Near Threatened, following IUCN Red List categories and criteria.

The genus Vitex L. (Lamiaceae, Viticoideae) comprises 45 native species in Madagascar, all but one of which are endemic to the country. Several new species are still to be described, and we propose here three new species from the littoral forests: V. mcphersonii Callm. & Phillipson, V. rabenantoandroi Callm. & Phillipson, and V. zigzag Callm. & Phillipson. These three distinctive new species grow in the threatened littoral forests of the east coast of Madagascar. The risk of extinction to these species was assessed following the IUCN Red List Criteria, revealing that V. mcphersonii should be assessed as “Vulnerable,” V. rabenantoandroi as “Near Threatened,” and V. zigzag as “Critically Endangered.” Each new species is provided with a discussion of its morphological affinities and a line drawing.
