Pacullidae is a family of araneomorph spiders first described by Eugène Simon in 1894. It was merged into Tetrablemmidae in 1958, then raised back to family status after a large phylogenetic study in 2017.
Flexicrurum is a genus of spiders from China similar to the genera Althepus and Leclercera. Tong and Li originally placed the genus in Ochyroceratidae, but Tong later moved it to Psilodercidae. Males are generally smaller than 2 mm, but the size of females is unknown. The name is derived from Latin flex "curved", and crur "leg", referring to the inner turned palpal tibia of the male. As of 2019 three described species have been found in caves of Hainan Island.
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.
Merizocera is a genus of six eyed spiders in the family Ochyroceratidae, first described by Jean-Louis Fage in 1912.
Psiloderces is a genus of six eyed spiders in the family Psilodercidae, first described by Eugène Simon in 1892
Speocera is a genus of six eyed spiders in the family Ochyroceratidae, containing fifty one species.
Pranburia is a monotypic genus of Southeast Asian ant mimicking corinnid sac spiders containing the single species, Pranburia mahannopi. Christa L. Deeleman-Reinhold described the first male in 1993, and the first female in 2001. It has only been found in Thailand, Cambodia, Laos, and Malaysia. The species is named after Narong Mahannop, one of the collectors of the holotype, and the genus is named after the Pranburi Province, where the male holotype was collected.
Trilacuna is a genus of goblin spiders native to Southeast Asia, first described by Tong & Li in 2007. They look similar to members of Silhouettella, but males can be distinguished by their large palpal femur, among several other more complicated defining features. The name is a combination of the Latin terms "tri" and "lacuna", referring to the three-branched endites in males and the three-notched labium in females.
Ablemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Friedrich Roewer in 1963.
Christa Laetitia Deeleman-Reinhold is a Dutch arachnologist. She graduated from the Leiden University in 1978. She specializes in spiders from Southeast Asia and Southern Europe, particularly cave-dwelling and tropical spiders. She donated a collection of about 25,000 Southeast Asian spiders, the largest collection of Southeast Asian spiders in existence, to the Naturalis Biodiversity Center in Leiden, The Netherlands. In addition to numerous articles, she has written the book Forest Spiders of South East Asia (2001). She is married to arachnologist Paul Robert Deeleman, with whom she has co-authored multiple publications.
Althepus is a genus of spiders in the family Psilodercidae. It was first described in 1898 by Tamerlan Thorell. As of 2019, it contains 60 species, all from Asia.
Psilodercidae is a family of spiders first described as a subfamily of Ochyroceratidae by Machado in 1951 and raised to family rank by J. Wunderlich in 2008. These spiders can be distinguished by the "segestriid positioning" of their six eyes, the absence of leg bristles, strong apical bristles on the cymbium, and several pairs of spermathecae in females.
Luzonacera is a genus of spiders in the family Psilodercidae. It was erected by Feng-Yuan Li and Shu-Qiang Li in 2017. As of February 2019, it contains five species found on the Philippine island of Luzon.
Sinoderces is a genus of spiders from Thailand in the family Psilodercidae first described in 2017. As of February 2019 it contains only two species.
Thaiderces is a genus of spiders from Thailand in the family Psilodercidae, family first described in 2017. As of February 2019 it contains only two species.
Priscaleclercera is a genus of araneomorph spiders in the family Psilodercidae, containing seven species. The genus was first described by Jorge Wunderlich in 2017, and its fossils have been found in Burmese amber, while live specimens have been found in Indonesia (Sulawesi).
Relictocera is a genus of southeast Asian araneomorph spiders in the family Psilodercidae, containing the single species, Relictocera qiyi. It was first described by F. Y. Li & S. Q. Li in 2017, and has only been found in Vietnam.
