Illustrated catalogue of type specimens of Megalopodidae (Coleoptera) deposited at the Museu de Zoologia da Universidade de São Paulo

Abstract The Museu de Zoologia da Universidade de São Paulo (MZUSP) houses an important Megalopodidae collection representing 144 species, especially from Brazil and the Neotropical fauna. The type specimens of some species have never been accessed since their original descriptions, and are thus unknown to a major part of the Megalopodidae researchers. Presented here is an illustrated catalogue of the megalopodid type specimens of 32 species deposited at MZUSP, featuring photos of habitus and labels, and complete label data of all the specimens, which originally belonged to Jacintho Guérins personal collection. Conflicting and inconsistent data provided in the literature and in the specimens labels are addressed. Taxa originally proposed as species varieties are here reaffirmed as valid, with subspecific rank. Agathomerus variansMonrós, 1945 and Plesioagathomerus vittatusMonrós, 1945, originally described as junior synonyms, are considered unavailable names. The subspecific epithet ngriapex is emended into Agathomerus bifasciatus nigrapexGuérin, 1949. An overview of the MZUSP Megalopodidae collection is presented with a history of the arrival of Guérins specimens.

Megalopodidae (Insecta, Coleoptera): new occurrence and host plant records for Brazil

Abstract The Brazilian Megalopodidae fauna consists of 147 species from 11 genera, of which Mastostethus Lacordaire is the most diverse, representing about half of the species. Nevertheless, knowledge about species distributions and their relationships with host plants is still scarce. Since this group has endophytic immatures and bore into branches, they are economically important as they mainly damage Solanaceae species. Thus, this study sought to determine the Megalopodidae species that occur in forest fragments of southwestern and western Paraná and associate them with their host plants. For this purpose, we used material collected with Malaise traps and active manual sampling to determine associations with host plants. A total of 170 specimens of 11 species were sampled, of which Pseudhomalopterus carinatus Pic, 1920 was the most abundant and collected in all fragments. Four species were sampled exclusively through manual collections and associated with their host plants, all of which were new association records for Brazilian megalopodides. Mastostethus pantherinus Lacordaire, 1845 was associated with an Asteraceae for the first time. Additionally, Mastostethus minutusMonrós, 1947 is a new record for Brazil.
