The fauna of Dynastinae (Scarabaeidae) on the island of Saba, Dutch Caribbean, was investigated through fi eldwork during 2006 to 2015. Three species, belonging to the three tribes Cyclocephalini, Pentodontini and Phileurini, are newly recorded from Saba and are discussed, with summaries of all relevant information from the West Indies. Detailed locality data, temporal distributions, and habitus photographs are presented for each species.
The fauna of Phanaeini of the northeast of Brazil was investigated through fieldwork in the States of Ceará, Maranhão and Piauí, and through study of preserved material from other states. Seven species of Phanaeini are newly recorded from these three states. Of these, two species are also new records for the northeast region: Phanaeus melibaeus Blanchard and an unidentified Dendropaemon Perty species. A total of 13 new state records are given for eight of the 15 species of Phanaeini recorded from the northeast to date, including three new state genus records. A key is provided for identification of all species. Detailed distributional information is presented together with habitat and bait preferences and other ecological data for each species. The diversity and distribution of the tribe in the northeast is discussed in the context of regional biotopes and wider geographic ranges. The fauna is shown to be more diverse than previously believed, containing both endemic and widespread elements occurring in species assemblages that differ according to habitat type and elevation, leading to substantial complementarity of diversity amongst the main biogeographic provinces and biotopes of the region.
