  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.

New georeferenced records of Tityus serrulatus Lutz & Mello, 1922 (Scorpiones: Buthidae) for state of Mato Grosso, midwestern Brazil

Abstract

We present additional records of Tityus serrulatus Lutz & Mello, 1922 (Scorpiones: Buthidae) for the state of Mato Grosso, midwestern Brazil. The record of this scorpion species, which can cause mild to severe envenomation, significantly contributes to the knowledge of scorpionism in the state, as well as to the mapping of its distribution in the Brazilian territory. A morphologically similar species is abundant in the area - Tityus confluens Borelli, 1899 (Scorpiones: Buthidae), also presenting a general uniform yellow coloration - but is usually responsible for less severe scorpion accidents. The correct identification of both species by health agents and the general population may be relevant for the appropriate treatment of local scorpion sting cases.
