Description of New Pseudeustetha species from Malaysia (Coleoptera: Chrysomelidae: Galerucinae s. str.)

The small oriental genus of Chrysomelidae, Pseudeustetha Jacoby, 1899 from Malaysia was studied. A total of eight species of the genus are recorded from Malaysia, of which seven are described as new to science: Pseudeustetha minima, P. nakasekoi, P. rufohirsuta, P. sabahcola, P. sarawacensis, P. sinarutensis and P. unicolor, n. spp. The occurrence of P. hirsuta (Jacoby) in Borneo (Sabah, Sarawak) and Peninsular Malaysia was not confirmed in this study. A tentative key to the 11 known species of the genus is provided.
