  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.

First record of the spider genus Diphya Nicolet 1849 (Araneae, Tetragnathidae) and new species from northern Peru

Abstract

Spiders of the genus Diphya (Nicolet) are characterized by having tibiae-tarsi I and II with stiff, curved prolateral setae. Currently, the genus comprises 21 species, six of which are recorded from America: the type species and three others from southern Chile (one also recorded in Argentina), one from Ecuador, and one from Brazil. Ba-sed on males and females collected in a montane forest in Cañaris, Lambayeque, northern Peru, a new species of Diphya, D. muchik sp. nov., is diagnosed, described, and illustrated. This represents the first record of the genus in Peru.
