  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.

Description of seven new species of Theraphosidae (Araneae, Theraphosinae; Ischnocolinae) from Ecuador, along with the identification of a new variation of type I urticating setae

Abstract

Seven Theraphosidae species are newly described from Ecuador: from the genus Pamphobeteus Pocock, 1901: Pamphobeteus contramina sp. nov. (male, female) and Pamphobeteus guacamayos sp. nov. (female); from the genus Thrixopelma Schmidt, 1994, Thrixopelma supay sp. nov. (female) and Thrixopelma michaeli sp. nov. (male); from the genus Hapalopus Ausserer, 1875, Hapalopus planetearth sp. nov. (female); and from the genus Holothele Karsch, 1879, Holothele incurva sp. nov. (male) and, Holothele tsala sp. nov. (female). Images of a male syntype of Pamphobeteus augusti (Simon, 1889) are included, along with a distribution map of all Pamphobeteus species found in Ecuador. The presence and distribution of urticating abdominal setae type I, III and IV are discussed, and a new variation of type I urticating setae is described.
