What is "maileus"

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. No study has been published on the genus since its first description.
