  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.

Integrative taxonomy describes a new species of the genus Dicranolasma Sørensen (Opiliones: Dicranolasmatidae) from Turkey

ABSTRACT

A new species, Dicranolasma gumushanensis sp. n., is described from the Gümüşhane Province of the northeastern region of Turkey, based on morphological and genetic evidence. The newly described species differs from similar species within the genus, particularly due to morphological characteristics such as the structure of the chelicerae and genitalia, and its molecular characteristics. A detailed description and diagnostic characteristics of the new species are provided, in addition to images of its body in dorsal view, chelicerae, pedipalps and genitalia. The nuclear (28S rRNA) and mitochondrial (COI) gene regions of the species were sequenced, revealing its phylogenetic relationships within the genus Dicranolasma.
