<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>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.

Wanda Wesołowska is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s.

<i>Afraflacilla karinae</i> Species of spider

Afraflacilla karinae is a species of jumping spider in the genus Afraflacilla that is found in South Africa. The spider was first defined in 2011 by Charles Haddad and Wanda Wesołowska. They originally placed the species in the genus Pseudicius, but Jerzy Prószyński moved it in 2017 to Afraflacilla on the basis of shape of its copulatory organs. Only the male has been described. The spider is brown and medium-sized, with a carapace typically 2.1 mm (0.083 in) long and an abdomen 2.7 mm (0.11 in) long. The spider has brown legs, with longer and thicker front legs. It stridulates using its legs and carapace. Afraflacilla karinae is superficially similar to many other spiders in both the genera Afraflacilla and Pseudicius. It is most like Afraflacilla zuluensis, particularly in its size, external appearance and distribution. The species is best identified by the short blunt dorsal apophysis, or appendage, on its palpal bulb.

<i>Afraflacilla roberti</i> Species of spider

Afraflacilla roberti is a species of jumping spider in the genus Afraflacilla that is found in Kenya. The spider was first defined in 2011 by Wanda Wesołowska. She originally placed the species in the genus Pseudicius, but Jerzy Prószyński moved it in 2017 to Afraflacilla on the basis of shape of its copulatory organs. The species is named after Robert Jackson, the collector who found the first example. The spider is small, with a cephalothorax between 1.7 and 1.6 mm long and an abdomen between 1.7 and 2.4 mm long. The female is larger than the male. The carapace is a dark brown elongated oval with a black eye field covered in white hairs. The abdomen is blackish-brown and is marked by two pairs of white patches and a small number of faint chevrons at the very rear. Some female examples have a generally featureless dark abdomen and others have additional small rounded patches at the edge. Some have light stripes to the front of the abdomen. The spider has yellow legs, apart from the front pair, which are brown, longer and stouter. It stridulates using its legs and carapace. Afraflacilla roberti can be differentiated from other species in the genus by its copulatory organs. The male has a long thin tibial apophysis. The female has narrow coiled insemination ducts.

<i>Afraflacilla refulgens</i> Species of spider

Afraflacilla refulgens is a species of jumping spider in the genus Afraflacilla that lives in Zimbabwe. The spider was first described in 2008 by Wanda Wesołowska and Meg Cumming. Originally allocated to the genus Pseudicius, it was moved to its current name by Jerzy Prószyński in 2016. The spider is small, with a dark carapace that is between 1.7 and 2.2 mm long and an abdomen between 1.9 and 3.0 mm long. It has a very dark, nearly black, eye field, although the male has a very thin white line behind the first row of eyes. The male abdomen is black with a pattern of white spots. The female abdomen is very dark brown, nearly black at the front and yellow to the rear. Both have a distinctive iridescent patch at the back of the abdomen that is recalled in the name of the species, which is a Latin word that can be translated “brilliant”. It is this iridescent patch that helps to distinguish the species, although a study of the copulatory organs is needed to confirm its identity. The legs are generally yellow, apart from the front pair on the male, which are brown, longer and stouter and used for stridulation.

<i>Afraflacilla altera</i> Species of spider

Afraflacilla altera is a species of jumping spider in the genus Afraflacilla that lives in South Africa and Zimbabwe. The spider was first described in 2000 by Wanda Wesołowska and originally allocated to the genus Pseudicius. It was moved to its current name by Jerzy Prószyński in 2016. The spider is small, with an elongated carapace and abdomen that are between 1.6 and 17 mm and between 2.1 and 2.6 mm long respectively. The male and female are similar in size and shape, although the female is generally lighter. They have a similar pattern of three white dots on each side of the brown abdomen. The spider is superficially almost indistinguishable from other species in the genus, particularly Afraflacilla karinae and Afraflacilla venustula. It can be best differentiated by its copulatory organs, particularly the shape of the male tibial apophyses, or appendages, and the arrangement of pouches and openings on the female epigyne.
