  Species diversity in the segmented spider genus Songthela (Mesothelae, Liphistiidae), with descriptions of 12 new species from Guizhou Province, China Abstract Twelve new species of the primitively segmented spider genus Songthela Ono, 2000, from Guizhou Province, China, are described based on the genital morphology of both sexes: S. chenjiapian sp. nov . (♂♀), S. cuantang sp. nov . (♂♀), S. fengxiang sp. nov . (♂♀), S. fuyan sp. nov . (♂♀), S. nanqiao sp. nov . (♂♀), S. parallela sp. nov . (♂♀), S. qingganglin sp. nov . (♂♀), S. tianba sp. nov . (♂♀), S. tudiao sp. nov . (♂♀), S. yanhe sp. nov . (♂♀), S. yinchiba sp. nov . (♂♀), and S. yuhu sp. nov . (♂♀). All new species are assigned to the multidentata -group based on the morphology of the male palp and female genitalia. Detailed diagnoses, descriptions, photographs, and a distribution map are provided. Mitochondrial cytochrome c oxidase subunit I ( COI ) sequences are also provided for the holotypes ...

Resurrection of Grammostola australis (Araneae: Theraphosidae) after seven decades: integrating molecular data, morphology, and distribution

Abstract

The name Grammostola australis Gerschman et Schiapelli, 1948, syn. resurr. is herein resurrected from synonymy with G. inermis Mello-Leitão, 1941, based on morphological and molecular evidence. The holotypes of both species are redescribed, and the female of G. australis is described for the first time. Diagnoses of these species are also provided. Phylogenetic analyses recovered G. inermis as a distinct lineage from G. australis, suggesting that both species are more closely related to Brazilian and Uruguayan species of the genus Grammostola Simon, 1892, than to other Argentinean species. Similarly, Chilean species appear distinct from other Grammostola species, indicating that the Andes act as a geographical barrier.
