  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...

Three new species of the orb-weaving spider genus Alpaida O. Pickard-Cambridge, 1889, the real male of A. guimaraes Levi, 1988 and the male of Aculepeira apa Levi, 1991 (Araneae: Araneidae)

Abstract

Three new species of Alpaida O. Pickard-Cambridge, 1889 are described from the Brazilian Amazon region: Alpaida tukano sp. nov., A. kayapo sp. nov. and A. tupinamba sp. nov. Alpaida murtinho Levi, 1988 is newly synonymized with A. guimaraes Levi, 1988 and the male originally associated with A. guimaraes is redescribed as A. tupinamba sp. nov. The true male of A. guimaraes is redescribed, and the male of Aculepeira apa Levi, 1991 is described for the first time.
