Nigorella is a spider genus of the Salticidae family (jumping spiders) from Africa.
Nigorella species are robustly built salticids with a body length ranging from 5.5 to 11 millimetres (1⁄4 to 1⁄2 in). The first pair of legs is just the longest. They are dark in colour with no distinct patterning. The genus is distinguished from others by the structure of the copulatory organs. The male pedipalp has a single short apophysis (outgrowth) on the tibia and bears a palpal bulb with a rounded tegulum and a short embolus with an additional terminal apophysis. The female epigyne is wider than long with two lateral copulatory openings. The inlet to the seminal ducts is hidden in deep cavities.
The genus Nigorella was erected in 2008 by Wanda Wesołowska and Beata Tomasiewicz for their newly described type species Nigorella aethiopica. The generic name was described as "an arbitrary combination of letters", feminine in gender. Three previously species described were transferred to the genus: Pachypoessa albimana as N. albimana, Philaeus manicus as N. manica, and Euophrys plebeja as N. plebeja. Subsequently it was discovered that Euophrys plebeja was a nomen dubium, with no known type specimen.N. hirsuta was added to the genus in 2009.
As of March 2017[update], the World Spider Catalog accepted the following species:
