| A survey of the scorpion fauna of the Island of Fernando de Noronha, Pernambuco (Brazil), was carried out in October 2005. Methods included active collecting and pitfall traps in several areas of the island under different degrees of human-caused alteration. Forty four scorpions, belonging to two species were collected: Isometrus maculatus (DeGeer, 1778), previously listed for the Island, and Tityus stigmurus (Thorell, 1877), here recorded for the first time. This species was probably introduced via cargo shipments from the continent and offers risk to the local population due to the gravity of the accidents. |

| Two new species of the Tityus genus are described. T. isabelceciliae n. sp lives on the northern central slope of the Cordillera de la Costa. It belongs to the discrepans group and is dangerous to man due to its high number, aggressive behavior, domiciliary habits, and high toxicity of its venom. T. isabelceciliae venom is similar to other Tityus in relation to the molecular weight range and the biological activity of its components. However, the proportions of each fraction in the venom pooled from many T. isabelceciliae differ from the proportions in other Tityus, indicating that these proportions may have a taxonomical value. The venom LD50 is 38.1 (36.3, 39.9) µg/g mouse (Death in 30 min, Dixon and Mood (14) sequential method, median and 95% confidence... |

| Two new scorpion species of the Buthidae family, Tityus ivic-nancor and Tityus sanarensis, are described in this paper. Both species belong to the "androcottoides" group and live from 1300 to 1400 m. above sea level near the town of Sanare (69º42'17.8"W, 9º45'3.9"N) in the southern part of the state of Lara in Venezuela. The number of Tityus species already known in Venezuela increases to 28 with the inclusion of these two new species. This paper includes a descriptive diagnosis and also a differential diagnosis of the species of Tityus that are geographically related to T. ivic-nancor and T. sanarensis. Drawings of the significant morphological characteristics of male and female specimens and a morphometric table are also included. |

| Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Costa Rica are produced by species in the genus Centruroides that are only mildly toxic to humans despite the existence of ion channel-active toxins in their venoms. Regional morbidity is low with the exception of Panama, where an incidence of 52 cases per 100,000 inhabitants was recorded for 2007, with 28 deaths from 1998 to 2006. Taxa belonging to the genus Tityus (also present in the Atlantic coast of... |

| Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil. Thelytokous parthenogenesis (with all-female broods) is most often observed. The only known exception to this is T. metuendus in which arrhenotoky (all-male broods) has been observed. In the present paper, current ideas regarding parthenogenesis in scorpions are summarized. The notion of geographic parthenogenesis ('parthénogenèse géographique'), coined by Vandel in 1928, is discussed. This rule is tentatively exemplified by a new case of parthenogenesis reported in a scorpion of the genus Tityus C. L. Koch,... |

| The present study aimed at verifying the impact of a Moroccan strategy against scorpion stings and, specifically, at identifying the epidemiological features of the patients envenomed or just stung by scorpions. The investigation included 4089 patients from a province of Morocco which were evaluated over three years (2001, 2002 and 2003). Most stings occurred during the hot period and mainly at night (between 6:00 p.m. and 12:00 p.m.). The average incidence was 2.8, the average age of the patients was 26.7±18.2 years, and the envenomation rate was 6.7%. Mortality rate was 0.05, and average lethality rate was 0.7%. Analysis of variance showed that young age, symptoms at admission, and long time elapsed between sting and admission were correlated with poor... |

| Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identified as L. quinquestriatus in Turkey) was classified as a new Leiurus species. This is the first report conducted on the lethality and biologic effects of L. abdullahbayrami scorpion venom in mice. In this study, the electrophoretic protein pattern of its venom was also determined. Two protein bands with molecular masses of 4 and 6 kDa were more strongly detected than other protein bands in the venom... |

| Ecuador harbors one of the most diverse Neotropical scorpion faunas, hereby updated to 47 species contained within eight genera and five families, which inhabits the “Costa” (n= 17), “Sierra” (n= 34), “Oriente” (n= 16) and “Insular” (n= 2) biogeographical regions, corresponding to the western coastal, Andean, Amazonian, and the Galápagos archipelago regions, respectively. The genusTityus Koch, in the family Buthidae, responsible for severe/fatal accidents elsewhere in northern South America and the Amazonia, is represented in Ecuador by 16 species, including T. asthenes, which has caused fatalities in Colombia and Panama, and now in the Ecuadorian provinces of Morona Santiago and Sucumbíos. Underestimation of the medical significance of scorpion envenoming... |

| Although the main Malian scorpion species of medical interest, Androctonus amoreuxi, is responsible for severe envenomings and perhaps some deaths, it has hitherto been considered not dangerous for humans. This population is located in the Saharian North-Eastern regions of Mali where it is accompanied by Leiurus quinquestriatus, a well known dangerous species of the Sahara. In the Gao district, divided by the Niger River, less desolate than the Tessalit and Kidal regions, one specimen of the dangerous species Androctonus australis was found. To summarize, Mali harbors at least three dangerous scorpion species: Leiurus quinquestriatus, Androctonus amoreuxi and A. australis, the latter recently having been identified in Mali for the first time. The absence... |

| Scorpions are venomous arthropods of the Arachnida class and are considered relatives of spiders, ticks and mites. There is not any study about the biochemical effects of Androctonus crassicauda (Olivier, 1807) venom. Therefore, in the present study, we aimed at evaluating the toxicity of the venom from A. crassicauda, which is responsible for a number of deaths of infants, children and adults in tropical and subtropical countries. For this purpose, rats (n=35) were divided into seven groups of five animals each; venom solutions (250µg/kg) were subcutaneously injected into rats; blood samples were taken from each animal at various times; and serum biochemical parameters were measured (levels of total proteins, total bilirubin, albumin, globulin, urea,... |

| Although it is a frequent accident in a few countries, scorpion envenomation during pregnancy remains scarcely studied. In the present study, the effects of repetitive maternal exposure to Buthus occitanus tunetanus venom are investigated and its possible embryotoxic consequences on rats. Primigravid rats received a daily intraperitoneal dose of 1 mL/kg of saline solution or 300 µg/kg of crude scorpion venom, from the 7th to the 13th day of gestation. On the 21st day, the animals were deeply anesthetized using diethyl-ether. Then, blood was collected for chemical parameter analysis. Following euthanasia, morphometric measurements were carried out. The results showed a significant increase in maternal heart and lung absolute weights following venom... |

| Among the various methods for evaluating animal venom toxicity, the calculation of the median lethal dose (LD50) is the most widely used. Although different protocols can be used to calculate the LD50, the source of the venom and the method of extraction, as well as the strain, age, and sex of the animal model employed, should be taken into consideration. The objective of the present study was to evaluate the influence of sex and age on the toxicity of Tityus serrulatus scorpion venom in Swiss mice. Although the symptoms of envenomation were similar in male and female animals, female mice proved to be more resistant to the venom. In females, age had no impact on the susceptibility to scorpion envenomation. Male mice were more sensitive to T. serrulatus... |

| Scorpion stings constitute a common type of accident in Turkey due to the geographic location, climate and socioeconomic structure of this country. Moreover, envenomation cases are considered a public health problem throughout Turkey. Based on data in the literature, the main clinical features of scorpion envenomations are defined as systemic manifestations including sweating, hypertension and vomiting, and among prominent causes of death are cardiorespiratory manifestations, toxic myocarditis and pulmonary edema. The most important health-threatening scorpions found in Turkey are: Androctonus crassicauda, Leiurus quinquestriatus, Mesobuthus gibbosus and Mesobuthus eupeus, all of which belong to the Buthidae family. This study indicates that there is no... |

| The following notes on gestation periods and litter size in seven specimens of Leiurus quinquestriatus are presented as observational data. Specimens of Leiurus quinquestriatus from southern Egypt and southern Israel were mated in the laboratory during 2007; afterwards, gestation periods and litter sizes of all females were recorded. Previous studies on this species reported that the gestation period ranged from 150 to 155 days and that litter size was between 12 and 99 offspring. In the present study, gestation periods in specimens from both geographic regions varied from 155 to 227 days and litter sizes were between 35 and 87 offspring. The current contribution expands on previously published data on gestation periods and supports previously reported... |
