Maileus is a monotypic genus of jumping spiders containing the single species, Maileus fuscus. It was first described by G. Peckham & Elizabeth Peckham in 1907,2 and is only found on Borneo.1 It is closely related to the genus Microhasarius.2

M. fuscus is known only from a single female, which is about 6 millimetres (0.24 in) long. Although no published drawings exist, Zabka has drawn the genitalia, and Proszynski has drawn the genitalia of both sexes of what is probably a different species of Maileus.3 No study has been published on the genus since its first description.1

Name

The species name is derived from Latin fuscus "dusky, brown".
