Binomial name | |
Marchena minuta (Peckham & Peckham, 1888)[1] | |
It forms a monophyletic group with the genera Afraflacilla, Pseudicius and Festucula.[3]
This species can easily be distinguished from others in its range by the tubercles on the first femur of its first legs.[2] M. minuta has a body length of about 4 mm.
The genus name is probably derived from the Spanish city of Marchena, Seville.[citation needed] As witnessed by other generic names, the describers had a habit of naming taxa after places unrelated to the species' distribution. The species name is Latin for "small, minute".
