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.
Menemerus davidi is a species of jumping spider in the genus Menemerus that lives in North Africa and the Middle East. The species was first identified in 1999 by Jerzy Prószyński and Wanda Wesołowska working initially independently, and then together. The first description was published by Wesołowska, one of over 500 descriptions she produced during her lifetime. The spider is small, with a carapace that ranges between 2.3 and 3.0 millimetres long and an abdomen that is 2.2 and 3.2 millimetres long, although the female is larger than the male. The carapace is generally a uniform dark brown while the abdomen has a pattern of a light brown stripe and white patches that serves to distinguish it from the related Menemerus animatus. Otherwise, it is its copulatory organs that most distinguish the species from others in the genus. It has distinctive internal structure to the female epigyne. The wide copulatory openings lead down the centre of the spider to the spermathecae while there is also a short narrower channel that runs to the rear of the spider with a prominent scent pore at the end. The male has a noticeably smaller embolus and a distinctive dorsal tibial apophysis.
Menemerus desertus is a species of jumping spider in the genus Menemerus that lives in Algeria. The species was first described in 1999 by Wanda Wesołowska, one of over 500 descriptions she produced during her lifetime. The spider is small, with a carapace that ranges between 2.5 and 2.7 millimetres long and an abdomen that is 2.7 and 4.7 millimetres long, although the female is larger than the male. The carapace is generally a uniform dark brown while the abdomen has a yellow stripe. Otherwise, it is its copulatory organs that most distinguish the species from others in the genus. The female epigyne has ridges at the entrance to the insemination ducts. The male has a distinctive dorsal tibial apophysis.
Evarcha flagellaris is a species of jumping spider in the genus Evarcha that lives in Kenya and South Africa. The species was first described in 2011 by Charles Haddad and Wanda Wesołowska. The spider is small, with a carapace measuring between 2.0 and 2.4 mm long and an abdomen between 1.9 and 3.6 mm long. The female is larger than the male, particularly in the size of its abdomen. Both have stripes on the abdomen, the male being more distinct with four brown stripes contrasting with a yellow background. This is similar to the related Evarcha striolata, from which it can be distinguished by the presence of an orange scutum. It can also be identified by its copulatory organs. The female has very wide looping insemination ducts that lead to heavily sclerotized multi-chambered spermathecae. The male has a long straight projection from its tibia or tibial apophysis and a whip-like embolus. It is after the latter feature that it is named.
Evarcha acuta is a species of jumping spider in the genus Evarcha that lives in Namibia, Seychelles and South Africa. The species was first described in 2006 by Wanda Wesołowska. The spider is small, with a carapace measuring typically 1.6 mm (0.06 in) long and an abdomen between 1.4 and 1.9 mm long. The carapace is light brown with a short black eye field. The abdomen has patterns that vary depending on geography. The holotype, found near Brandberg Mountain in Namibia, has lines of brown patches on the top. Examples found in Free State, South Africa, have black lines on the top and sides. The spider can be most easily distinguished from other spiders in the genus by its copulatory organs. The male has a distinctive notch on a long straight projection from its tibia known as a tibial apophysis and a long embolus. The female has not been described.
