ABSTRACT. Leuserattus gunung Prószyński et Deeleman-Reinhold, 2012, the type species of a monotypic genus, is redescribed in the light of new morphological data. The known distribution of this species is extended from Sumatra to Java, Indonesia. A second species — Leuserattus pristinus sp.n. (♂♀) from the canopy rainforest of Borneo — is diagnosed and described. The new species is distinct from L. gunung by the body colour pattern, cheliceral armament, and the conformation of copulatory organs in both sexes. A close relationship of the genus Maileus with Leuserattus is suggested; relationships with Saaristattus Logunov et Azarkina, 2008 and Muziris Thorell, 1878 are discussed. The epigyne of the type specimen of Maileus fuscus Peckham et Peckham, 1907 is illustrated.

KEY WORDS: Aranei, canopy fogging, jumping spiders, Southeast Asia, taxonomy, tropical rainforest.
