Vailimia is a genus of Asian jumping spiders. The type species was described in 1907 from a single male about 6 millimetres (0.24 in) long. It was originally thought to be close to Harmochirus, but the male pedipalp, chelicera, and cephalothorax drawn by Proszynski in 1984, and information gained from later collected specimens indicates otherwise. Subsequently, five more species have been identified. It may be a synonym for Pancorius.
Psechridae is a family of araneomorph spiders with about 70 species in two genera. These are among the biggest cribellate spiders with body lengths up to 2 centimetres (0.79 in) and funnel webs more than 1 metre in diameter.
The Tiaojishan Formation is a geological formation in Hebei and Liaoning, People's Republic of China, dating to the middle-late Jurassic period. It is known for its exceptionally preserved fossils, including those of plants, insects and vertebrates. It is made up mainly of pyroclastic rock interspersed with basic volcanic and sedimentary rocks. Previously, the Tiaojishan Formation was grouped together with the underlying Haifanggou Formation as a single "Lanqi Formation." The Tiaojishan Formation forms a key part of the Yanliao Biota assemblage.
Phrurolithidae is a family of araneomorph spiders first described by N. Banks in 1982. First included in the Corinnidae as the subfamily Phrurolithinae, later phylogenetic studies justified a separate family.
Utivarachna is a genus of Asian araneomorph spiders in the family Trachelidae first described by Kyukichi Kishida in 1940. It was largely ignored until Christa L. Deeleman-Reinhold revised the sac and ground spiders in 2001, transferring some species from Trachelas and adding several new ones. The genus was further expanded in 2014 and 2015.
This list of fossil arthropods described in 2012 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that have been described during the year 2012. The list only includes taxa at the level of genus or species.
Hermosa is a genus of jumping spiders first described by G. W. Peckham and E. G. Peckham in 1892, and synonymized with Myrmarachne in 1901. In 2016, Jerzy Prószyński split up Myrmarachne, creating nine new genera, all with names beginning "Myrm". However, it turned out that Myrmavola volatilis, the type species of Myrmavola, was also the type species of Hermosa, and Myrmavola was made a junior synonym. It is part of the Myrmarachnini tribe within the Salticoida clade of Salticinae.
Troglocoelotes is a genus of east Asian funnel weavers. It was first described by B. Li, Z. Zhao and C. T. Zhang in 2019, and it has only been found in China.
Erigomicronus is a genus of sheet weavers erected by A. V. Tanasevitch in 2018 for two east Asian species. In the following week, B. K. Seo published the new genus Collis for three Korean species. Further investigation revealed that all five belonged to the same genus, and preferences was given to the one published mere days before the other.
Kakameganula is a monotypic genus of east African jumping spiders containing the single species, Kakameganula holmi. The genus was first described by Angelika Dawidowicz & Wanda Wesołowska in 2016 under the name "Kakamega", and was placed in subtribe Thiratoscirtina within the tribe Aelurillini of the Salticoida clade of Salticinae.
Bucliona is a genus of sac spiders first described by Pierre L.G. Benoit in 1977. As of November 2021 it contains only three species: B. dubia, B. jucunda, and B. kirilli. It was synonymized with Clubiona in 1997, but was elevated back to genus in 2021. The type species was originally described under the name "Clubiona dubia".
Indopadilla is a genus of jumping spiders first described by J. T. D. Caleb, P. M. Sankaran and K. S. Nafin in 2019. It was placed into the tribe Baviini in the Salticoida clade of Salticinae. Several species have been transferred from the genus Bavia.
Shuqiang Li is a Chinese arachnologist and a professor at the Institute of Zoology of the Chinese Academy of Sciences. Li is best known for his work with spiders and has described hundreds of new species and many genera. He is Editor in Chief of the journal Zoological Systematics.
Asianopis is a genus of Asian net-casting spiders first described by Y. J. Lin, L. Shao and A. Hänggi in 2020.
Halocosa is a genus of wolf spiders first described by G. N. Azarkina and L. A. Trilikauskas in 2019. As of December 2021 it contains only three species: H. cereipes, H. hatanensis, and H. jartica. The type species, Halocosa cereipes, was originally described under the name "Lycosa cereipes".
Tangguoa is a small genus of east Asian cellar spiders. It was first described by Z. Y. Yao, Y. P. Luo and S. Q. Li in 2021, and it has only been found in China. As of March 2022 it contains only two species: T. laibin and T. tongguling.
Bosselaerius is a genus of Asian spiders in the family Phrurolithidae. It was first described by Alireza Zamani and Yuri M. Marusik in 2020. As of March 2022 it contains only three species: B. daoxianensis, B. hyrcanicus, and B. tajikistanicus.
