Pseudomogrus guseinovi

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.
