Cybaeidae is a family of spiders first described by Nathan Banks in 1892. The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.
Azerithonica is a genus of Asian funnel weavers containing the single species, Azerithonica hyrcanica. It was first described by E. Guseinov, Yuri M. Marusik & S. Koponen in 2005, and has only been found in Azerbaijan.
Paracedicus is a genus of Asian araneomorph spiders in the family Cybaeidae, and was first described by Victor R. Fet in 1993. First placed as a subgenus of Cedicus, it was elevated to genus status in 2003.
Cepheia is a monotypic genus of European araneomorph spiders in the family Synaphridae containing the single species, Cepheia longiseta. It was first described as Theonoe longiseta in 1881, and was moved to its own genus in 1894. Originally placed with the tangle-web spiders, it was moved several times before settling in the Synaphridae in 2003. Paolo Brignoli noted that it is an unidentifiable theridiid.
Synaphris is a genus of araneomorph spiders in the family Synaphridae, and was first described by Eugène Louis Simon in 1894. Originally placed with the tangle web spiders, it was moved to the Symphytognathidae in 1973, and to the Synaphridae in 2003.
Raveniola is a genus of spiders in the family Nemesiidae, first described in 1987 by Zonstein.
Carpathonesticus caucasicus is a species of araneomorph spider of the family Nesticidae. It occurs in Georgia, where it is found in caves.
Aelurillus brutus is a species of jumping spider in the genus Aelurillus that lives in Kazakhstan and Turkmenistan. The female was first described by Wanda Wesołowska in 1996 and the male by Galina Azarkina in 2003. The spider is small with a carapace that is between 2.5 and 3.2 mm long and an abdomen between 2.4 and 4.7 mm in length. The female is larger than the male. The spider is generally dark brown and hairy, but the male abdomen has a pattern of grey-yellow wavy lines. The difference between this species and others in the genus are subtle. The females are particularly difficult to distinguish. However, there are three distinctive stripes on the eye field and a pattern on the bottom of the abdomen.
Aelurillus kopetdaghi is a species of jumping spider in the genus Aelurillus that lives in Turkmenistan. It was first described in 1996 by Wanda Wesołowska. The species is dark brown and medium-sized, with a bristly carapace that is between 3.4 and 3.5 mm long and a hairy abdomen that is between 3.2 and 4.1 mm long. The female is larger than the male. They also differ in details, such as the colour of the pedipalps, which are orange and brown respectively. The copulatory organs of the female are superficially similar to other species in the genus, like Aelurillus v-insignitus, but the internal structure is more complex.
Chalcoscirtus lepidus is a species of jumping spider in the genus Chalcoscirtus that has been found in Afghanistan, Iran, Tajikistan,Turkmenistan and Uzbekistan. The spider was first described in 1996 by Wanda Wesołowska, although the first male was identified three years later. The spider is small, with a carapace between 1.06 and 1.2 mm long and an abdomen between 1.03 and 2.2 mm long. The female is larger and lighter than the male and has three narrower stripes on the back while the male has a large scutum. In both cases, the carapace is plain. The scutum and lack of pattern on the carapace help distinguish the spider from related species. It can also be identified by its copulatory organs, particularly the long curved embolus on the male and the position of the copulatory openings on the female epigyne, which differ from the otherwise similar Chalcoscirtus infimus.
Pseudomogrus mirandus is a species of jumping spider in the genus Pseudomogrus. It has been found in Turkmenistan on the steppe, although it may also live in Afghanistan and Iran. The species was first defined by Wanda Wesołowska in 1991, one of over 500 described by the arachnologist. She originally placed it in the genus Yllenus, but was moved to the new genus Logunyllus in 2016, and then to its present designation in 2019. The spider is small, with a carapace measuring between 1.6 and 1.78 mm long and an abdomen between 1.4 and 2.3 mm long. The male has a red-brown or dark brown carapace and dark grey abdomen, the female a brown carapace and greyish-brown abdomen. All have a covering of small white scales. The spider has yellow legs. The copulatory organs are distinctive and enable the spider to be distinguished from others in the genus. The female epigyne has a half-moon-shaped pocket and simple insemination ducts that lead to spherical spermathecae. The male lacks the ventral tibial apophysis common in other species and has a compound terminal apophysis that is of a similar length to its thin embolus.
Silometopoides is a genus of sheet weavers that was first described by K. Y. Eskov in 1990.
Cozyptila is a genus of crab spiders that was first described by Y. M. Marusik, Pekka T. Lehtinen & M. M. Kovblyuk in 2005. As of July 2020 it contains three species, found in Europe and on Cyprus: C. blackwalli, C. guseinovorum, and C. nigristernum.
Phintella parva is a species of jumping spider in the genus Phintella that lives in China, Japan, Korea and Russia. The species was first described by Wanda Wesołowska in 1981 based on a holotype from North Korea. However, retrospectively; it was recognised that other examples of the spider had been previously collected and, at one time, a description published without a species name. The spider is small, between 3.5 and 4 mm long, and yellow. The female is slightly larger than the male. The abdomen has a striped pattern and the carapace has circular markings, but the most distinguishing difference between this species and other members of the genus are its copulatory organs, particularly the short curved embolus on the male and long straight insemination ducts in the female.
Phintella pygmaea is an endemic species of jumping spider in the genus Phintella that lives in China. It was first described in 1981 by Wanda Wesołowska from a holotype discovered in Guangdong. Only the female has been identified. The spider is small, with a brown cephalothorax and yellow abdomen. It has distinctive half-crescent markings on the cephalothorax and a ridge marked by two depressions on the small epigyne.
Plexippoides regius is a species of jumping spider in the genus Plexippoides. The species was first described by Wanda Wesołowska in 1981 based on specimens from North Korea but its distribution has been extended to include China, Russia and South Korea, with examples found as far as Sichuan. The spider is small, with a body length between 6.9 and 8.65 mm, the female being generally larger than the male. It is distinguished by the two brown lines that stretch across the back of its carapace and abdomen that is recalled in its Korean name. Otherwise, the spider varies in coloration, with some examples having an orange or yellow-brown carapace and others dark brown. The male has a long embolus that encircles the palpal bulb. The female has complex seminal ducts that lead to heavily sclerotised and many-chambered spermathecae.
Persiscape is a genus of funnel weavers first described by Alireza Zamani and Yuri M. Marusik 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".
Yuri Mikhailovitch Marusik is a Russian arachnologist.
Pseudomogrus guseinovi is a species of jumping spider in the genus Pseudomogrus that lives in Azerbaijan, Kazakhstan and Turkmenistan. It thrives in desert and semidesert environments, including the Repetek Biosphere State Reserve in the Karakum Desert. The species was first described by Dmitri Logunov and Yuru Marusik in 2003. They originally placed it in the genus Yllenus, but it was moved to the new genus Logunyllus in 2016, and then to its present designation in 2019. The spider is small, with a carapace that is between 2.13 and 2.63 mm long and an abdomen between 2,13 and 2.7 mm long. The female is larger than the male. The male has a distinctive white pattern on its body, including two white stripes and a white "A" on its eye field. The female has a distinctive deep pocket in its epigyne that is shaped like the Greek letter Greek: Π. Other aspects of the female copulatory organs also help distinguish the spider from other members of the genus, including the shape of the insemination ducts and spermathecae.
