Two new species of the spider genus Loxosceles (Araneae, Sicariidae) from the Ecuadorian Andes

Abstract

Two new species of the spider genus Loxosceles (Araneae: Sicariidae) from the Ecuadorian Andes are described: Loxosceles guayllabambasp. nov. (male, female) and Loxosceles binfordaesp. nov. (male, female). Both species are part of the second most speciose “laeta” group, which include twenty-four described species. Only three species are known to occur on mainland Ecuador, and one species in the Galapagos. The synonymy of L. alicea under L. rufescens is rejected, detailed SEM of the female internal genitalia and a map of all the species from mainland Ecuador are presented.
