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

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 Guérin’s 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 varians Monrós, 1945 and Plesioagathomerus vittatus Monrós, 1945, originally described as junior synonyms, are considered unavailable names. The subspecific epithet ngriapex is emended into Agathomerus bifasciatus nigrapex Guérin, 1949. An overview of the MZUSP Megalopodidae collection is presented with a history of the arrival of Guérin’s specimens.

A revision of Peltariosilis Wittmer (Coleoptera: Cantharidae), a surprisingly diverse Amazonian radiation

Abstract PeltariosilisWittmer, 1952 is a South American Silinae genus characterised by the highly modified male pronotum and scutellum with a remarkable lamellar projection. Six species were previously recognised. The study of numerous specimens from previously unsampled localities and the revision of previously studied material shows that Peltariosilis is far more diverse than previously recognised. 15 species are here recognised as valid, nine of which are described as new: P. brancuccii, P. brunneoapicalis, P. cleidecostae, P. diversicollis, P. flavicornis, P. gracilicornis, P. major, P. orientalis and P. parviscutellaris spp. nov. A comparative study and new morphological terminologies are introduced for pronotum, scutellum and male genitalia. All Peltariosilis species are described and illustrated, including the first illustration of a female pronotum, and an identification key is provided. A map is given, including records of all known Peltariosilis, showing a distribution confined to the Amazonian subregion (Suriname, French Guiana, N Brazil, E Peru and NE Bolivia). The identity of the type species P. scutulata (Wittmer, 1952), hitherto considered as broadly distributed and highly variable, is addressed through study of their type series and additional specimens from widespread localities.

Systematics, bionomy, and metamorphosis of Coleoptera (Insecta): Papers celebrating the 80th birthday of Cleide Costa

We present a brief biography of Dr. Cleide Costa, eminent entomologist from Museu de Zoologia da Universidade de São Paulo (MZUSP). She has been dedicating the last six decades to the study of adults and immatures of Coleoptera. Dr. Costa is the pioneer in collecting and rearing immature beetles in Brazil, being responsible for establishing the most extensive Latin American collection of reared immatures Coleoptera. We discuss central aspects of her personal history, as well as career landmarks and achievements. A compilation of taxa introduced to science by her, taxa named in her honor, and a full list of her scientific, educational and cultural production are provided in chronological order. More than a biographical account, this publication is an acknowledgment of Dr. Cleide Costas legacy to entomology.
