  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.

An unusual new species of Burmesescorpiops Lourenço, 2016 from Cretaceous Burmese amber (Scorpiones: Palaeoeuscorpiidae: Archaeoscorpiopinae)

Abstract 

In this contribution a third new species of the rare genus Burmesescorpiops Lourenço, 2016 is described. The discovery of this new element belonging to the family Palaeoeuscorpiidae Lourenço, 2003 and to the subfamily Archaeoscorpiopinae Lourenço, 2015 brings further elements to support the validity of the genus Burmesescorpiops. This generic group remains however, poorly speciose. The remarkable degree of diversity in the Burmese amber-producing forests is once again highlighted.
