Description of a new species of Leuserattus Proszynski et Deeleman-Reinhold, 2012, with comments on the type species L. gunung Proszynski et Deeleman-Reinhold, 2012 and associated genera(Araneae: Salticidae)

摘要

Leuserattus gunung Proszynski et Deeleman-Reinhold, 2012, the type species of a mono-typic 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. (O1) 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 Malleus with Leuserattus is suggested; relationships with Saaristattus Lo-gunov et Azarkina, 2008 and Muziris Thorell, 1878 are discussed. The epigyne of the type specimen of Malleus fuscus Peckham et Peckham, 1907 isillustrated.
