  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 Hamataliwa Keyserling, 1887 from Xizang, China (Araneae, Oxyopidae)

Abstract

Three new species of Hamataliwa Keyserling, 1887, collected from Xizang, China, are described: H. jinlini Wang & Mi, sp. nov. (♂♀), H. qomolangma Wang & Mi, sp. nov. (♂♀), and H. shufui Wang & Mi, sp. nov. (♂♀). The dissected bulb of the genus is shown for the first time. Diagnostic photos of the habitus and copulatory organs, as well as a map of the collecting localities of the type specimens for the new species, are provided. DNA barcodes of all new species were obtained for future reference.
