<i>Afraflacilla</i> Genus of spiders

Afraflacilla is a genus of the spider family Salticidae. Most species are distributed in Eastern to Northern Africa and Australia, with two species found in Europe. This genus was for a time included in the genus Pseudicius, and the boundaries between both genera are disputed. In 2016 Jerzy Prószyński erected the genus Psenuc for some borderline species. The name Afraflacilla is combined from Africa, where most earlier described species were found, and FlacillaSimon, 1901, an obsolete salticid genus now called FlacillulaStrand, 1932. This genus name is in turn derived from Aelia Flaccilla, wife of Roman Emperor Theodosius I. Afraflacilla, Pseudicius, Festucula and Marchena are close relatives and form a monophyletic group.

<i>Langona</i> Genus of spiders

Langona is a genus of spiders in the family Salticidae. Langona species are similar to those of the genus Aelurillus. In 2015, it was listed in the subtribe Aelurillina. The subtribe is allocated to the tribe Aelurillini in the clade Saltafresia. In 2017, it was grouped with nine other genera of jumping spiders under the name Aelurillines.

<i>Menemerus</i> Genus of spiders

Menemerus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1868. They are 4 to 10 millimetres long, flattened in shape, and very hairy, usually with brown and grayish hairs. Most species have white edges on the thorax. The abdomen is often oval, or sometimes elongated or rounded.

<i>Pseudicius</i> Genus of spiders

Pseudicius is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek pseudo "false" and the salticid genus name Icius. The small genus Wesolowskana should possibly be included in this genus. There is some dispute whether Afraflacilla is a distinct genus or should be included in Pseudicius. Festucula and Marchena are other close relatives, these genera form a monophyletic group.

All species have two white longitudinal stripes on the carapace, and both sexes show strong bristles around the eyes. The name is a combination of the Greek sten- "narrow" and the salticid genus Aelurillus.

<i>Euophrys elizabethae</i> Species of spider

Euophrys elizabethae is a species of jumping spider in the genus Euophrys that is endemic to South Africa. The species was first described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith and named after the arachnologist Elizabeth Peckham. It is a small brown spider, with a body that consists of a cephalothorax that is between 2.2 and 2.3 mm long and an abdomen between 2.2 and 2.6 mm (0.10 in) long. The cephalothorax has a plain but darker carapace, or topside, and a lighter sternum, or underside, while the abdomen has a mosaic pattern of lighter and darker patches that differ in detail between the sexes. The copulatory organs are unique amongst spiders in the genus. The male has a shorter and wider tibial apophysis than related species. The female has shorter accessory glands and longer and more strongly curved insemination ducts.

<i>Euophrys leipoldti</i> Species of spider

Euophrys leipoldti or the Karoo Euophrys Jumping Spider is a species of jumping spider in the genus Euophrys that is endemic to South Africa. It lives in karoo and succulent karoo. The female was first described in 1903 by George and Elizabeth Peckham and the male in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith. It is a small spider, with a body that consists of an oval cephalothorax that measures between 1.9 and 2.1 mm long and a narrower abdomen that is between 1.8 and 2.4 mm long. The female has a larger abdomen than the male. The spider is generally yellowish-brown to brown, although some examples have a darker topside of the cephalothorax, or carapace. The spider has a mottled pattern on its abdomen. The male has slightly longer brown front legs, the remainder being yellow. The female has yellowish-brown legs that have brown patches and rings. Its copulatory organs are distinctive. The female has the longest insemination ducts in the genus and the male has an unusual spiral embolus.
