  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
A new species of the genus Actinopus Perty, 1833, belonging to the cucutaensis group, is described from Colombia. The new species, Actinopus embera sp. nov., was discovered in the departments of Córdoba, Bolivar, Sucre, and Atlántico, located along Colombia’s Caribbean coast, and is readily distinguished by genital organ morphology. Additionally, we report a possible case of phoresis between a mite of the family Acaridae Latreille, 1802 and a female and three immature specimens of Actinopus embera sp. nov. from one of the type localities (Tiquisio, Bolí var). Finally, based on prior evidence and the events leading to the destruction of the type material, we propose Actinopus cucu taensis Mello-Leitão, 1941 as a species inquirenda.
