  Systematics of the Aliatypus erebus Group (Mygalomorphae, F. Antrodiaetidae): Exploring a Possible Ring of Species Around the California Central Valley (Full Text Dissertation or Thesis) The Aliatypus erebus group represents a monophyletic radiation of trapdoor spiders with a ring-like distribution around California's Central Valley, shaped by long-term geological events and exhibiting substantial cryptic diversity and geographic structuring. Additional topics discussed include: Phylogenomic methods using ultra conserved elements (UCE) Impact of tectonic activity and fault systems on species diversification Cryptic speciation and species delimitation in low-dispersal arthropods Hays, T.

A new species of the genus Sarax Simon, 1892 (Amblypygi, Charinidae) from China

Abstract

A new species of the whip spider genus Sarax Simon, 1892 collected from Guangdong Province, China is diagnosed and described based on morphological characters: Sarax quinquespinus sp. nov. (♂♀). With this third Sarax species recorded in China, the geographical gap in its distribution between Yunnan to Fujian is filled. In addition, a distribution map and the photos of living male and female, copulatory organs and other structures are provided.
