Systematics, Morphology and Physiology


We present a list of Passalidae species found in the westmost Brazilian Amazon region, which is considered to be a diversity-rich area due to being a tectonic and geographic transition zone in relation to Brazilian Amazon lowlands and the Andean range. The specimens acquired in field collections and museums were analyzed. Their geographical distributions were estimated based on data from labeled specimens and the literature. Twenty-nine species belonging to two subfamilies, six genera, and four subgenera were listed. Among them, 20, 1, and 2 showed to be new records for the region, Brazilian Amazon, and Brazil, respectively. An identification key is provided for the species being listed.

We would like to thank Fernando Bernardo Gouveia Pinto, Gleic Sá, João Vicente, and Plínio for their support in the field collections; the curators of the collections, Márcio Luis de Oliveira (INPA), Fábio Siqueira Pitaluga de Godoi (UFAM), and Orlando Tobias Silveira (MPEG) who kindly let us study the analyzed samples; Dmitri V. Logunov (MUHD) for kindly sending us the holotype of Passalus umbriensis Hincks; Sônia Casari (MZSP) for kindly receiving MB at the Museu de Zoologia de São Paulo and allowing the study of the syntypes Passalus elfriedae Luederwaldt; and Jorge Manuel Antunes for his help on revising the English version of the original manuscript.

Authors’ Contributions

MB analyzed and identified the vouchers, took the photos, and wrote the article. CRVF planned and executed the project, analyzed the species, and reviewed the article.

Funding Information

We would like to thank the Instituto Nacional de Pesquisas da Amazônia (INPA) for funding the collections. MB thanks Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES for granting the scholarship by way of PROTAX 001/2015 “Estudos sistemáticos para as famílias Psephenidae, Scarabaeidae e Torridincolidae (Coleoptera: Polyphaga e Myxophaga) e análise filogenética do subgênero Ontherus (Scarabaeidae: Scarabaeinae): grupos taxonômicos negligenciados na Amazônia”.
