L OURENÇO Abstract: A synopsis of the fossil scorpions found in amber, from the Lower Cretaceous to the Miocene, is presented. Scorpion remains are rare among the arthropods found trapped in amber. Only five specimens are known from Cretaceous amber, repre- senting four different taxa, whereas eleven specimens have been recorded from Baltic amber, representing nine genera and ten species. A few, much younger, fossils have also been described from Dominican and Mexican ambers. Key words: Cretaceous, Paleocene, Miocene, Scorpiones.

Tityus antilla~us (Thorell, 1877), originally described from two juveniles from the "Antilles," is a junior synonymof T. crassimanus. Tityus crassin~nus appears to be most closely related to Tityus michelii Armas,from Puerto Rico. Htyus obtusus (Karsch, 1879), from Puerto Rico, has been confused with, and erroneously suspected of be/rig a junior synonymof T. crasgmaT:us. INTRODUCTION Thoreil (1877) describedsix species in the genusIsometrus Hemprich and Ehrenberg, four of them from the NewWorld. Isometrus fuscus Thorell, 1877, from Argentina was subsequentlydesignated the type species of the genusZabius Thorell, 1894. Isometrus stigmurusThorell, 1877, fromBrasil wastransferred to Tit)~s C.

Isometruscrassimanus Thorell, 1877, fromMexico was also transferred to ~’tyus, whereit has remainedenigmatic (Hoffmann 1932) primarily because the genus ~tyus is otherwise unknownnorth of Costa Rica in either Central or North America(Pocock 1902, Lourenfoand Franckein press).

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. -

Tityus Asthenes (Pocock, 1893)
Tityus asthenes (Pocock, 1893) by Michiel Cozijn Fig. 1:T.asthenes adult couple from Peru, top: ♀, down: ♂ M.A.C.Cozijn © 2008 What’s in a name? Tityus asthenes has no generally accepted common name, but they are sometimes sold under names like “Peruvian black scorpion” or as other species like Tityus metuendus (Pocock, 1897). Etymology: The name ‘asthenes’ in apposition to the generic name (Tityus) literally means weak or sick in ancient Greek, but it refers to ‘a thin or slender habitus’ in this case. M.A.C.Cozijn © 2011 All text and images. E-mail :[email protected] 1 Fig.2: part of South and Central America (modified) © Google maps 2011 Distribution Colombia, Costa Rica, Ecuador, Panama, Peru (1). Natural habitat T.asthenes is a common element of the tropical forests of Eastern Amazonia. T.asthenes can be found on tree trunks, but also on the forest floor under fallen logs and other debris, aswell as in the rootsystems of large trees. They are more common in rural areas. In Costa Rica the species is considered rare (Viquez, 1999). Most of the specimens in the hobby circuit originate from Peru, leading me to believe it is rather common in that country. Venom The LD50 value of the venom is 6.1 mg/ kg, and this value seems rather high when compared to T.serrulatus Lutz & Mello 1922 (0.43 Zlotkin et al, 1978) or T.bahiensis Perty 1833 (1.38, Hassan 1984). A study in Colombia revealed that systemic effects occurred mostly in children. Eighty patients where studied, of which fourteen sought medical help in a hospital. -

ABSTRACT: This work reports the second record of the scorpion Tityus bahiensis Perty from Venezuela. The specimen was found alive in a wardrobe at a hotel resort in Margarita Island, northeastern Venezuela. Morphological characterization allowed its assignment to the Tityus bahiensis population inhabiting the southernmost area of the species’ geographic range, e.g. the state of São Paulo in Brazil, northern Argentina and Paraguay. The fact that the only available Venezuelan antiscorpion (anti-Tityus discrepans) serum does not neutralize the effects of alpha- and beta- toxin from Tityus serrulatus venom (which resembles in composition that of T. -
