  A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala Abstract  A new species of the spider genus Euagrus Ausserer, 1875 from temperate pine-oak forests in the states of Tlaxcala and Hidalgo, Mexico is described: E. pulque sp. nov. The description of the new species is based on male and female adult specimens. Additionally, Euagrus gus Coyle, 1988 is recorded for the very first time in the state of Tlaxcala. These species have sympatric distributions in La Malinche National Park, Tlaxcala. With this description, the diversity of the genus increases to 23 species, with Mexico harboring the highest diversity with 17 described species.  Valdez-Mondragón, A., Salinas-Velasco, H.

Scorpion sting envenomation: should it be considered a neglected tropical disease?

Abstract

At least 2772 species of scorpion (Arachnida: Scorpiones Koch, 1837) have been described.1 Of these, only 104 species (3.8%) are medically relevant.2 Mexico has the highest biodiversity, with 12% of all scorpion species worldwide.3,4 Other countries with a high incidence of scorpion sting envenomation include Brazil, Iran and Morocco2,5–7 (Table 1). Despite the high incidence and the disproportionate number of cases in marginalized areas of the world, scorpion sting envenomation is not formally recognized as a neglected tropical disease (NTD) by the World Health Organization (WHO).8 However, snakebite envenomation is an official NTD according to the WHO, and PLOS (Public Library of Science) Neglected Tropical Diseases acknowledges that scorpion sting envenomation has many features that characterize NTDs.9
