  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...

A new species of the genus Cicurina Menge, 1871 (Araneae: Cicurinidae) from Hachijojima Island, Tokyo, with notes on the congeners in Japan and China

Abstract
A new species of Cicurina, C. auster sp. nov. is described from Hachijojima Island, Tokyo, Japan. The morphology of the copulatory organs of the new species is similar to those of some Cicurina species known in China, while it is clearly different from all the known species from Japan. The results of a comparative examination between the new species and congeners from Japan and China are presented. A presumption about a possibility of the human introduction of the new species from the Ryukyu Islands is mentioned.
