Popilius gibbosus (Burmeister, 1847) was known only from localities in the Cordillera Oriental of the northern Andes in Colombia and Venezuela and the southern section in Colombia between 1,350-3,000 m. Herein, we provide the first record for Bolivia at low elevations (< 1,000 m), thus extending the geographic and altitudinal range of this species. Information about characters not yet used and the first description of the aedeagus are provided, accompanied with figures of those characters that facilitate the identification of the species. An identification key for Popilius species in Bolivia and a P. gibbosus distribution map are also provided.

Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized.(AU)

Pupae of chafer beetle (Melolonthidae) Cnemida retusa (Fabricius, 1801) (Rutelinae, Rutelini) were collected in October and November of 2017 in a decaying log at Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brazil, and are described and illustrated. The pupa description is the first to the genus and a key to known pupae of Rutelini is added.
