ABSTRACT A new species of Ananteris Thorell, 1891 (Scorpiones, Buthidae C. L. Koch, 1837) is described from rain forest in the area of the Ouarimapan river in the South of French Guyana. The new species Ananteris sabineae n. sp. is related to Ananteris pydanieli Lourenço, 1982. The two species can readily be distin- guished by: 1) much paler pigmentation of pedipalps and legs in A. sabineae n. sp., with only diffused spots; 2) darker pigmentation of carapace and KEY WORDS tergites in A. sabineae n. sp., with less conspicuous yellow spots; 3) differences Arachnida, Scorpiones, in cheliceral dentition: in A. sabineae n. sp. the movable finger has two basal Buthidae, teeth, whereas in A. pydanieli only one is present; the median and basal teeth Ananteris, of the fixed finger are more conspicuous in A. pydanieli. This is the fourth French Guyana, neotropics, species of Ananteris described from French Guyana. The total number of new species. species in the genus is now raised to 24.

Tityus antilla~us (Thorell, 1877), originally described from two juveniles from the "Antilles," is a junior synonymof T. crassimanus.

  • Effects of Brazilian Scorpion Venoms on the Central Nervous System
    Nencioni et al. Journal of Venomous Animals and Toxins including Tropical Diseases (2018) 24:3 DOI 10.1186/s40409-018-0139-x REVIEW Open Access Effects of Brazilian scorpion venoms on the central nervous system Ana Leonor Abrahão Nencioni1* , Emidio Beraldo Neto1,2, Lucas Alves de Freitas1,2 and Valquiria Abrão Coronado Dorce1 Abstract In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus, T. bahiensis, T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus, T. silvestres, T. brazilae, T. confluens, T. costatus, T. fasciolatus and T. neglectus are also found in the country, but the incidence and severity of accidents caused by them are lower. The main effects caused by scorpion venoms – such as myocardial damage, cardiac arrhythmias, pulmonary edema and shock – are mainly due to the release of mediators from the autonomic nervous system. On the other hand, some evidence show the participation of the central nervous system and inflammatory response in the process. The participation of the central nervous system in envenoming has always been questioned. Some authors claim that the central effects would be a consequence of peripheral stimulation and would be the result, not the cause, of the envenoming process. Because, they say, at least in adult individuals, the venom would be unable to cross the blood-brain barrier. In contrast, there is some evidence showing the direct participation of the central nervous system in the envenoming process. This review summarizes the major findings on the effects of Brazilian scorpion venoms on the central nervous system, both clinically and experimentally.

  • Homeowner Guide to Scorpions and Their Relatives
    HOMEOWNER Guide to by Edward John Bechinski, Dennis J. Schotzko, and Craig R. Baird CIS 1168 Scorpions and their relatives “Arachnid” is the scientific classification category for all eight-legged relatives of insects. Spiders are the biggest group of arachnids, with nearly 3800 species known from the U.S and Canada. But the arachnid category includes other types of eight-legged creatures that sometime cause concern. Some of Idaho’s non-spider arachnids – such as scorpions -- pose potential threats to human health. Two related non-spider arachnids – sun scorpions and pseudoscorpions – look fearsome but are entirely harmless. This publication will help you identify these three groups and understand the threats they pose. All three of these groups almost always are seen as lone individuals that do not require any control.

Mitchell2 Introduction shrimp can deliver to an unsuspecting finger during sorting of the shrimp from the by-catch. The only whip scorpion found in the United States is the giant whip scorpion, Mastigoproctus giganteus giganteus (Lucas). The giant whip scorpion is also known as the ‘vinegaroon’ or ‘grampus’ in some local regions where they occur. To encounter a giant whip scorpion for the first time can be an alarming experience! What seems like a miniature monster from a horror movie is really a fairly benign creature. While called a scorpion, this arachnid has neither the venom-filled stinger found in scorpions nor the venomous bite found in some spiders. One very distinct and curious feature of whip scorpions is its long thin caudal appendage, which is directly related to their common name “whip-scorpion.” The common name ‘vinegaroon’ is related to their ability to give off a spray of concentrated (85%) acetic acid from the base of the whip-like tail. This produces that tell-tale vinegar-like scent. The common name ‘grampus’ may be related to the mantis shrimp, also called the grampus. The mantis shrimp Figure 1. The giant whip scorpion or ‘vingaroon’, Mastigoproctus is a marine crustacean that can deliver a painful wound giganteus giganteus (Lucas). Credits: R. Mitchell, UF/IFAS with its mantis-like, raptorial front legs. Often captured with shrimp during coastal trawling, shrimpers dislike this creature because of the lightning fast slashing cut mantis 1.

  • A Redescription and Family Placement of Uintascorpio Perry, 1995 from the Parachute Creek Member Of
    ARTÍCULO: A REDESCRIPTION AND FAMILY PLACEMENT OF UINTASCORPIO PERRY, 1995 FROM THE PARACHUTE CREEK MEMBER OF THE GREEN RIVER FORMATION (MIDDLE EOCENE) OF COLORADO, USA (SCORPIONES: BUTHIDAE) Jorge A. Santiago-Blay, Michael E. Soleglad & Victor Fet Abstract: The monotypic genus Uintascorpio Perry, 1995 from the Parachute Creek Member of ARTÍCULO: the Uinta Basin in the Green River Formation, Colorado, USA (Middle Eocene; ap- A redescription and family proximate age 48 Ma) is redescribed and placed in the family Buthidae (parvorder placement of Uintascorpio Perry, Buthida). The placement of this fossil in the Buthidae is supported by the diagnostic 1995 from the Parachute Creek carination of the pedipalp, metasoma, and other morphological details. This fossil is the Member of the Green River most ancient known record of the Buthidae in the New World and the oldest North Formation (Middle Eocene) of American scorpion fossil since Carboniferous. The existence of Uintascorpio halandra- Colorado, USA sorum reflects a long Cenozoic history of buthid evolution in North America.
