  The distribution, spatial clustering, and density of trapdoor spiders in two California coastal dune ecosystems Abstract Coastal dune ecosystems support endemic trapdoor spiders, yet population data for these species are limited. We conducted the first coastal dune trapdoor spider population estimation surveys at Moss Landing State Beach (California) and for Aptostichus stephencolberti Bond 2008 at Sunset State Beach using randomly selected 1m 2 quadrats across ~26,000 m 2 per site. Burrow densities were similar between sites (Sunset: 0.287 burrows/m 2 ; Moss: 0.453 burrows/m 2 ), yielding estimated population sizes of ~35,206 and ~30,959 individuals, respectively. However, spatial analyses revealed contrasting patterns of burrow distribution. At Sunset State Beach, burrow presence was strongly associated with vegetation and occurred closer to plants, despite vegetation being randomly distributed. In contrast, no vegetation–burrow association was detected at Moss Landing, alth...

Three new species of the wolf spider genus Sinartoria Wang, Framenau & Zhang, 2021 (Araneae, Lycosidae) from southern China

Abstract

Three new species of the wolf spider genus Sinartoria Wang, Framenau & Zhang, 2021 are described from China: Sinartoria dui sp. nov. (♂♀, Guangxi), S. maolan sp. nov. (♀, Guizhou) and S. nanling sp. nov. (♀, Guangdong). Morphological descriptions, photographs, illustrations of copulatory organs and a distribution map are provided. Additionally, photographs of living species of this genus are provided for the first time.
