Se presenta una lista actualizada de los escorpiones de Bolivia. Se rnencionan 24 especies (tres de elias con dudas) y una subespecie, perte­ necientes a las familias Bothriuridae, Buthidae e luridae.

Twenty four species (three of them, with doubts) and one subspecies, belonging to the families Bothriuridae, Buthidae and luridae are listed. For each species, an abbreviated bibliographic reference and the com­ plete list of known localities are given. Brachistosternus ferrugineus (Thorell) and the Andean genus Orobothriurus Maury (Bothriuridae) are mentioned for the first time from Bolivia. Seven nominal species cited by previous authors are excluded from the Bolivian scorpiofauna, and the reasons for these exclu­ sions are discussed. All Bolivian localities where scorpions have been collected are listed in a gazetteer. KEYWORDS. Neotropics. Bolivia. Checklist. Scorpiones. Distribution.

E-mail: [email protected] & [email protected]; [email protected] Abstract Bothriurus nendai n. sp. is described. This species is endemic to the upper level of the Somuncura plateau, a Patagonian island placed in the Monte Phytogeographic province. This is the third known endemic scorpion from this area. Bothriurus nendai n. sp. is closely related to the patagonicus group; however, several morphological characters separate B. nendai from the species of this group. New data on the scorpion species of the plateau are also provided. Key words: Scorpiones, Patagonia, Argentina, Somuncura, Bothriuridae, Bothriurus, endemism Introduction The Patagonian scorpion fauna has received little attention by taxonomists until recent years; however, in the last decade several papers have been published on this subject (Acosta 2003; Mattoni 2007; Ojanguren- Affilastro 2001, 2003, 2007; Ojanguren-Affilastro & Cheli 2009; Ojanguren-Affilastro & Roig-Alsina 2001). Most of the scorpions of this area belong to genus Bothriurus Peters 1861, with five described species: B. burmeisteri Kraepelin 1894, belonging to the burmeisteri group; B. patagonicus Maury 1969, B. sanctaecrucis Mattoni 2007, and B. ceii Ojanguren-Affilastro 2007, belonging to the patagonicus group (Mattoni 2007; Maury 1969; Ojanguren-Affilastro 2007); and B.

On the other hand, Brachistosternus coquimbo n. sp occurs at high altitudes in the Andes mountain chain and is related to Brachistosternus (L.) montanus Roig Alsina, 1977, and to several Andean species from Argentina and Chile.

  • Taxonomic Updates in Scorpions
    The Scorpion Files – Occasional Papers 1. 2007 (ISSN 1504-7342) Taxonomic updates in scorpions (Arachnida: Scorpiones) since the publication of the Catalogue of the Scorpions of the World (1758-1998) (Fet, Sissom, Lowe, & Braunwalder, 2000). Part 1: Bothriuridae. Jan Ove Rein1 1Medical Library, University Library in Trondheim – Norwegian University of Science & Technology, St. Olav Hospital, Parkbygget, N-7006 Trondheim, Norway Summary: In the end of 2006, the Family Bothriruridae consists of 14 genera and 129 species: Bothriurus (41), Brachistosternus (36), Brazilobothriurus (1), Centromachetes (3), Cercophonius (7), Lisposoma (3), Orobothriurus (9), Pachakutej (6), Phoniocercus (2), Tehuankea (1), Thestylus (3), Timogenes (5), Urophonius (11) & Vachonia (1). Introduction: Bothriuridae has representatives in South America, Africa (southern part), Asia (India) and Australia, where they are found in temperate and subtropical habitats. One genus has recently been discovered in the Himalayas (Cercophonius). Members of this family are found in small burrows, under stones, in cracks and crevices, and in self-made burrows up to 40 cm deep. Methods: Information about taxonomical changes in the period 1998 - 2006 has been collected through intensive searching in major databases like Zoological Records, Biological Abstracts, Pubmed (Medline) and others. Another important source of information has been researchers around the world sending me new papers on scorpion taxonomy, or informing me about new changes. Results/Discussion: New genera and species and genera and species that have undergone taxonomic updates since the Catalogue of the Scorpions of the World (Fet et al., 2000) are listed alphabetically. Genera- and species-names in brackets [ ] are no longer considered valid. Genera- and species-names in quotation marks “ “ are taxa with an unresolved status/incertae sedis.

Thus, stenotopic species and those with low-dispersal ability will likely be negatively affected by landscape modifications that reduce environmental complexity.

[email protected] The Western Ghats, one of the “biodiversity hot spots” of the world, is home to large numbers of arachnids of which spiders have a huge share. However, compared to other hot spots of the world, spiders of the Western Ghats are a poorly worked out group. Biota of this area is the product of drastic climatic, ecological and biogeographical history. A few studies are conducted to reveal the faunal affinity of the Western Ghats with other regions of the world.

The combination of an anatomical study using methylene blue as the contrast medium together with a histological analysis using hematoxylin-eosin and Heindenhain´s iron hematoxylin techniques permitted the identkfication of a large number of nerves in B. bonariensis. Many of these are also present in a variety of other species of scorpions, belonging to distinct families of the order Scorpiones. Nev- ertheless, two pairs of nerves from B. bonariensis originating in the cheliceral ganglion, one pair of esophageal nerves and one pair of nerves from the aortic arch, appear to diverge from this basic orga- nization. They have not been previously described, nor have any equivalents been reported in research on other scorpion species, in which the current homological criteria have been employed. Key-words: scorpion, Bothriurus, nervous system, ganglia, anatomy.

  • Love Bites – Do Venomous Arachnids Make Safe Pets?

Hauke 1,#, and Volker Herzig 2,#,* 1 Munich, 81377, Germany; [email protected] 2 School of Science & Engineering, GeneCology Research Centre, University of the Sunshine Coast, Sippy Downs, QLD 4556, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-7-5456-5382 # These authors contributed equally to this study Abstract: With a global estimate of tens of thousands of arachnid enthusiasts, spiders and scorpions are gaining increasing popularity as pets in industrialised countries in Europe, Northern America and Asia. As most spiders and all scorpions are venomous and due to their mostly negative image in the public media, several governments are already considering introducing legislation to regulate the domestic care of potentially dangerous captive animals. We aimed to investigate the circumstances and effects of exposure to arachnids kept in captivity. Thus, we collected and analysed data from 335 reported bites and stings attributed to pet arachnids. Our data revealed that on average there were less than 20 recorded envenomations per year with ~90% preventable by due care. We also categorized the severity of the resulting symptoms and found that the vast majority of symptoms were either local (60.9%) or moderate (33.4%), 4.8% were asymptomatic, only 0.9% were severe and no fatalities were recorded. Based on our database of bite and sting reports, we performed a risk assessment for arachnid pet ownership and concluded that with the proper care arachnids can be safely kept as pets and pose a lower risk than many other recreational activities.
