  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.

Synanthropic species of spiders – those that live in associationwith or benefit from humans and their environments – mayhunt various types of arthropods inside houses (Uhlenhaut, 2001).Among other taxa, numerous species of synantrhopic spiders preyon other spiders. This feeding behaviour is particularly common in spiders of the genus Pholcus Walckenaer, 1805, which havebeen observed preying on a variety of araneomorph spider taxa (Uhlenhaut, 2001; Sherwood, 2019). In Poland, the genus Pholcus is represented by three species (Nentwig et al., 2024).
