  Huntsman spiders of the genus Sinopoda (Araneae, Sparassidae, Heteropodinae) from the Honghe Hani and Yi Autonomous Prefecture, southwestern China, with descriptions of two new species Abstract Spiders of the genus Sinopoda Jäger, 1999 from Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, China are studied. A total of four species are reported and illustrated of which two, Sinopoda honghe Yu & Zhong, sp. nov . and Sinopoda kuan Yu & Zhong, sp. nov ., are described as new to science. The other two previously described species from this region: S. tengchongensis Fu & Zhu, 2008 and S. tumefacta Zhong, Jäger, Chen & Liu, 2019 are also illustrated. Detailed descriptions, diagnoses, illustrations and DNA barcodes of the two new species are given. A distribution map of these four species in Honghe is provided.

Revisiting evolutionary relationships of Antrodiaetus (Araneae, Mygalomorphae, Antrodiaetidae) using phylogenomics; implications for species diversity and biogeography of a persistent Holarctic lineage

Abstract

Antrodiaetus is a lineage of mygalomorph spider (Mygalomorphae: Antrodiaetidae) that has persisted since the late Cretaceous and has a disjunct Holarctic distribution and strong morphological conservatism. These folding-door spiders possess a life history (i.e., limited dispersal, conserved environmental niche) that closely ties their evolution to geology. This study produces a robust, well-supported phylogenomic inference of all currently recognized Antrodiaetus species using UCEs (Ultraconserved Elements), corroborates previous biogeographical hypotheses, and proposes new hypotheses about diversification patterns. We also confirm that previously suspected cryptic diversity within A. pacificus is underestimated, as this nominal species comprises multiple divergent and cryptic lineages. Our phylogeny now serves as a foundation for understanding Antrodiaetus species relationships, biogeography, and speciation.
