Debido a la fragmentación de esta información encontrada en registros bibliográficos, se tomó como objetivo reunir y actualizar esta información, determinar cuál es la ofidiofauna del Chaco y de sus subregiones, y elaborar mapas de registros de cada una de las especies. Además se analizó la diversidad funcional, taxonómica y filogenética entre las subregiones chaqueñas, bajo la hipótesis de que las características ambientales condicionan la diversidad funcional, -
Reserva Natural Laguna Blanca, Departmento San Pedro
Russian Journal of Herpetology Vol. 23, No. 1, 2016, pp. 25 – 34 RESERVA NATURAL LAGUNA BLANCA, DEPARTAMENTO SAN PEDRO: PARAGUAY’S FIRST IMPORTANT AREA FOR THE CONSERVATION OF AMPHIBIANS AND REPTILES? Paul Smith,1,2 Karina Atkinson,2 Jean-Paul Brouard,2 Helen Pheasey2 Submitted December 30, 2014. Geographical sampling bias and restricted search methodologies have resulted in the distribution of Paraguayan reptiles and amphibians being patchily known. Available data is almost entirely based on brief collecting trips and rapid ecological inventories, often several decades apart, which inevitably struggle to detect more inconspicuous species and patterns of abundance. This has led to a deficit in our knowledge of the true distribution and abun- dance of Paraguayan reptiles and amphibians. The establishment of the NGO Para La Tierra at Reserva Natural Laguna Blanca (RNLB), Depto. San Pedro, Paraguay allowed the first modern sustained, multi-method inventory of Paraguayan reptiles and amphibians to be performed at a single site. Despite the small size of the reserve (804 ha), a total of 57 reptiles (12 of national conservation concern) and 32 amphibians (one of national conserva- tion concern) were collected during five years of random sampling, qualifying RNLB as the most biodiverse re- serve for reptiles and amphibians in the country. Six species occurring at RNLB have been found at no other Para- guayan locality. Legal protection for this private reserve expired in January 2015 and the conservation implica- tions of the inventory results are discussed. It is proposed that the long term legal protection of the reserve be con- sidered a national conservation priority and that the diversity of the herpetofauna be recognized with the designa- tion of RNLB as Paraguay’s first Important Area for the Conservation of Amphibians and Reptiles. -

True Or False Coral Snake: Is It Worth the Risk? a Micrurus Corallinus Case
Strauch et al. Journal of Venomous Animals and Toxins including Tropical Diseases (2018) 24:10 https://doi.org/10.1186/s40409-018-0148-9 CASE REPORT Open Access True or false coral snake: is it worth the risk? A Micrurus corallinus case report Marcelo Abrahão Strauch1,2*†, Guilherme Jones Souza1,4†, Jordana Nahar Pereira3, Tyelli dos Santos Ramos1, Marcelo Oliveira Cesar1,2, Marcelo Amorim Tomaz2, Marcos Monteiro-Machado2, Fernando Chagas Patrão-Neto2 and Paulo A. Melo2* Abstract Background: Bites provoked by the genus Micrurus represent less than 1% of snakebite cases notified in Brazil, a tiny fraction compared with other genus such as Bothrops and Crotalus, which together represent almost 80% of accidents. In addition to their less aggressive behavior, habits and morphology of coral snakes are determinant factors for such low incidence of accidents. Although Micrurus bites are rare, victims must be rescued and hospitalized in a short period of time, because this type of envenoming may evolve to a progressive muscle weakness and acute respiratory failure. Case Presentation: We report an accident caused by Micrurus corallinus involving a 28-year-old Caucasian sailor man bitten on the hand. The accident occurred in a recreational camp because people believed the snake was not venomous. The victim presented neurological symptoms 2 h after the accident and was taken to the hospital, where he received antielapidic serum 10 h after the bite. After the antivenom treatment, the patient presented clinical evolution without complications and was discharged 4 days later. Conclusions: We reinforce that it is essential to haveahealthcarestructuresuitableforthetreatmentofsnakebite.

E-mail: [email protected] Abstract The genus Micrurus comprises 123 currently recognized taxa (species and subspecies) that are traditionally arranged in four species groups diagnosable mainly by color pattern characteristics. Here, we describe a new species of triadal coral snake from northeastern Brazil. The new species is distinguished from other sympatric triadal congeners (M. lemniscatus carvalhoi, M. ibiboboca and M. brasiliensis) mainly by the entirely black parietals and by a suite of external characters and hemipenial morphology. The new species appears to be restricted to tropical ombrophilous lowland coastal forests of northeastern Brazil and all recently collected specimens are known to occur in small forest patches surrounded by periur- ban environment, which calls for an urgent evaluation on its conservation status. -
First Record of Male Combat for Micrurus Hemprichii (Serpentes: Elapidae)
Herpetology Notes, volume 14: 181-183 (2021) (published online on 26 January 2021) First record of male combat for Micrurus hemprichii (Serpentes: Elapidae) Vinícius Mendes1,*, Diederik C. Lock2, Daniel Loebmann1, and Omar Machado Entiauspe-Neto1 Male combat is known to occur in several snake species Micrurus hemprichii (Jan, 1858) is a coral snake (Senter et al., 2014). The larger body in a male can allow species characterised by the presence of three to nine victories in these ritualistic combats, providing access black or grey triads (8–12 dorsals long), divided by to copulation. These behaviours are more frequently orange or brownish rings (3–4 dorsals long), black or present in dimorphic species in which males are larger grey head, usually with a yellow nuchal ring, single in body size than females (Shine, 1994), suggesting cloacal plate, 156–199 ventral scales, 22–34 subcaudals, that ritualistic combat can positively select larger males 1+1 temporals (Campbell and Lammar, 2004; Silva-Jr. et (Shine, 1978).

Cañas et al. Journal of Venomous Animals and Toxins including Tropical Diseases (2017) 23:9 DOI 10.1186/s40409-017-0100-4 CASEREPORT Open Access Envenomation by the red-tailed coral snake (Micrurus mipartitus) in Colombia Carlos A. Cañas1*, Fernando Castro-Herrera2 and Santiago Castaño-Valencia2 Abstract Background: Although the red-tailed coral snake (Micrurus mipartitus) is widely distributed in Colombia and its venom is highly neurotoxic and life threatening, envenomation by this species is rare. Therefore, this report may shed some light on the clinical presentation of M. mipartitus bites. Case presentations: Herein, we describe two cases of patients bitten by red-tailed coral snakes, illustrating the clinical presentation of the victims, the outcomes and treatment provided. Conclusion: Envenomation caused by M. mipartitus provokes predicable neurotoxicity, and its treatment should be based on respiratory support and use of specific antivenom. Keywords: Red-tailed coral snake, Micrurus mipartitus, snake envenomation, Colombia Background have a cylindrical body, rounded small heads, very small Envenomation caused by snake venoms remains a eyes and short thick tails.

The following is a work in progress and is intended to be a printable quick reference for the venomous snakes of the world. There are a few areas in which common names are needed and various disputes occur due to the nature of such a list, and it will of course be continually changing and updated. And nearly all species have many common names, but tried it simple and hopefully one for each will suffice. I also did not include snakes such as Heterodon ( Hognoses), mostly because I have to draw the line somewhere. Disclaimer: I am not a taxonomist, that being said, I did my best to try and put together an accurate list using every available resource. However, it must be made very clear that a list of this nature will always have disputes within, and THIS particular list is meant to reflect common usage instead of pioneering the field. I put this together at the request of several individuals new to the venomous endeavor, and after seeing some very blatant mislabels in the classifieds…I do hope it will be of some use, it prints out beautifully and I keep my personal copy in a three ring binder for quick access…I honestly thought I knew more than I did…LOL… to my surprise, I learned a lot while compiling this list and I hope you will as well when you use it…I also would like to thank the following people for their suggestions and much needed help: Dr.Wolfgang Wuster , Mark Oshea, and Dr. Brian Greg Fry. -

Paulo 48(3):141-145, May-June, 2006 BITES BY CORAL SNAKES (Micrurus spp.) IN CAMPINAS, STATE OF SÃO PAULO, SOUTHEASTERN BRAZIL Fábio BUCARETCHI(1,5), Stephen HYSLOP(2,5), Ronan José VIEIRA(3,5), Adriana Safioli TOLEDO(5), Paulo Roberto MADUREIRA(4,5) & Eduardo Mello DE CAPITANI(3,5) SUMMARY Coral snakes (Micrurus spp.) are the main representatives of the Elapidae in South America. However, bites by these snakes are uncommon. We retrospectively reviewed the data from 11 individuals bitten by coral snakes over a 20-year period; four were confirmed (snake brought for identification) and seven were highly suspected (neuromuscular manifestations) cases of elapid envenoming. The cases were classified as dry-bite (n = 1, caused by M. lemniscatus; did not receive antivenom), mild (n = 2, local manifestations with no acute myasthenic syndrome; M. frontalis and Micrurus spp.), moderate (n = 5, mild myasthenia) or severe (n = 3, important myasthenia; one of them caused by M. frontalis). The main clinical features upon admission were paresthesia (local, n = 9; generalized, n = 2), local pain (n = 8), palpebral ptosis (n = 8), weakness (n = 4) and inability to stand up (n = 3). No patient developed respiratory failure. Antivenom was used in ten cases, with mild early reactions occurring in three. An anticholinesterase drug was administered in the three severe cases, with a good response in two. No deaths were observed. Despite the high toxicity of coral snake venoms, the prognosis following envenoming is good.
