  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.

Redescription of Centruroides infamatus (Scorpiones: Buthidae) and description of a new species of “striped” scorpion of the “infamatus” subgroup from north-central México

Abstract

Centruroides infamatus (C.L. Koch) is redescribed based on individuals obtained from a population from the León, Guanajuato region, in central Mexico. The species is redescribed because in the original description only the country is mentioned as the type locality with no further details. Also, Centruroides rommeli sp. nov. is described based on individuals obtained from a population of scorpions from Jalpa, municipality of Jalpa in the southern region of the state of Zacatecas, Mexico. This species is placed in the subgroup "infamatus" as part of the "striped" scorpions. Morphological comparisons are carried out with C. suffusus (Pocock) and C. vittatus (Say), both species that belong to the same subgroup talso recorded in Zacatecas. Additionally, is included the redescription of C. infamatus, because the population of the new species was previously identified with this specific name. Centruroides rommeli sp. nov. is sympatric with Mesomexovis spadix (Hoffmann), scorpions of the Vaejovidae family.
