  On a new genus of dwarf tarantulas ( Araneae : Mygalomorphae : Theraphosidae ) endemic from Peru: evidence from morphology and molecular phylogeny, with description of three new species Abstract Recent field campaigns conducted in Peru along with the examination of museum specimens allowed us to identify small tarantulas that do not fit with any known Theraphosidae genera. Morphology and additional molecular evidence from the mitochondrial gene COI led us to propose Kiskalla gen. nov . from southern Peru, at Puno region. Three new species of Kiskalla gen. nov . ( K. ignacioi sp. nov ., K. yeisoni sp. nov . and K. zukuapasanka sp. nov .) are herein described, diagnosed and illustrated. Kiskalla gen. nov . differs from the known Theraphosinae genera in the presence of lateral stripes on the abdomen and a small dorsal arrowhead-shaped patch of type III urticating setae, presence of a large number of spines on all legs, short and stout setae on the dorsal metatarsi encirc...

New synonymy in Thalerommata Ausserer, 1875 (Araneae: Mygalomorphae: Theraphosidae)

Abstract

A morphological study of the type material of two Colombian theraphosid species in the genus Thalerommata Ausserer, 1875, deposited in the European spider collections of the Natural History Museum, London, and Muséum national d'Histoire Naturelle, Paris, enables us to establish a new synonym: T. macella (Simon, 1903) is designated as a junior synonym of T. gracilis Ausserer, 1875.
