Nigorella is a genus of jumping spiders that was first described by Wanda Wesołowska & Beata Tomasiewicz in 2008. The name is described as "an arbitrary combination of letters", feminine in gender.[2] 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.[2] Subsequently it was discovered that Euophrys plebeja was a nomen dubium, with no known type specimen.[3]

Description

They 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 the longest. They are dark in color, with no distinct patterning.

Members of this genus can be distinguished from others by the structure of the copulatory organs. The male pedipalp has a single short apophysis on its tibia. The palpal bulb has 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.[2][3]

Species

As of July 2019 it contains eight species, found in Asia and Africa:[1]

Nigorella aethiopica Wesolowska & Tomasiewicz, 2008 (type) – Ethiopia
Nigorella albimana (Simon, 1902) – West and Central Africa
Nigorella hirsuta Wesolowska, 2009 – Zimbabwe, South Africa
Nigorella hirticeps (Song & Chai, 1992) – China
Nigorella hunanensis (Peng, Xie & Kim, 1993) – China
Nigorella manica (Peckham & Peckham, 1903) – Zimbabwe
Nigorella petrae (Prószyński, 1992) – Thailand
Nigorella sichuanensis (Peng, Xie & Kim, 1993) – China

gollark: I, for one, am using my atoms for nonpaperclip purposes and somewhat need them.

gollark: So you're arguing that the marginal value of a vaccine to everyone isn't great because it does not get substantially closer to eradication?

gollark: And?

gollark: The effectiveness in general scales with how many people have it and how good the vaccines are individually. We want to maximize that. So... it's sensible to reduce one factor because the other is lower?!

gollark: This is a... very bizarre argument?
