Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
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.
Paraneaetha is a monotypic genus of Egyptian jumping spiders containing the single species, Paraneaetha diversa. It was first described by J. Denis in 1947, and is only found in Egypt. The name is a combination of the Ancient Greek "para" (παρά), meaning "alongside", and the salticid genus Neaetha.
