  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.

Abstract

Two new species from the family Araneidae are described: a new species from the monotypic orb-weaving genus Spinepeira Levi, 1995, Spinepeira erwini sp. nov. (♀), and a new species of Scoloderus Simon, 1887, Scoloderus neilli sp. nov. (♀), are described from the Ecuadorian Amazon. Both species were collected with insecticidal canopy knockdown. Furthermore, herein, we present the first images of Spinepeira’s internal genitalia, and the first country record of Pozonia Schenkel, 1953 is reported with Pozonia bacillifera (Simon, 1897) collected in the canopy of Tiputini in Ecuador.
