Maileus is a spider genus of the Salticidae family (jumping spiders). Its only species M. fuscus is only known from Sarawak and Sumatra. According to its original describers it is closely related to the genus Microhasarius.M. fuscus is known only from a single female which is about 6 mm 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.
