A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala

  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.

Restriction of the Type Locality “Los Puentes”, Ecuador, for Several Species of Arachnida, Gastropoda and Plants

 


Restriction of the Type Locality “Los Puentes”, Ecuador, for Several Species of Arachnida, Gastropoda and Plants

“Los Puentes” in northwestern Ecuador has been cited as the type locality for several spider, gastropod, and plant taxa. Yet, earlier works ambiguously described it as “near Quito,” leading to confusion about its location. By examining historical documents, maps, and an official decree, I verify that “Los Puentes” lies near Nanegalito, Pichincha province, on the northwestern slopes of the Western Cordillera of the Andes of Ecuador, at 1200–1500 m elevation. I formally restrict the type locality for multiple species, including Isomeria bourcieri lutea Cousin 1887 (Gastropoda: Labyrinthidae), Guestieria locardi Jousseaume 1887 (Gastropoda: Scolodontidae), Proserpinella cousini Jousseaume 1887 (Gastropoda: Proserpinellidae), Mesembrinis vesperus Jousseaume 1887 (Gastropoda: Achatinidae), Idiophthalma robusta Simon 1889 (Arachnida: Barychelidae), Eurypelma (Lasiodora) augusti Simon 1889 (Arachnida: Theraphosidae), Eurypelma (Lasiodora) vespertinus Simon 1889 (Arachnida: Theraphosidae), Asplundia nonoensis Harling 1958 (Pandanales: Cyclanthaceae), and Blakea eriocalyx Wurdack 1979 (Myrtales: Melastomataceae), ensuring taxonomic clarity.
