A catalogue of the type specimens of the family Buprestidae (Insecta: Coleoptera) housed at the "Museo of La Plata", Argentina.

We provide information on the type specimens of Neotropical species of Buprestidae (Coleoptera: Buprestoidea) deposited at the Museo de La Plata (MLP). Among them, there are syntypes of 45 species of J. Obenberger, and syntypes, holotypes or paratypes of species described by C. Berg, A. Cobos and Ch. Kerremans, plus lectotypes and paralectotypes designated based on syntypes of Obenberger' species. Besides, we compiled a list of 37 species which specimens are labeled as types (metatypes or homotypes), but in fact these specimens were compared with the types by the authors of the species (e.g. C. Burmeister, J. Obenberger, Ch. Kerremans). Moreover, we provide information on missing types (formerly at the MLP but not in the collection at present) and specimens labeled as types of species never described. Most species herein treated were collected in Argentina by the specialist M. Viana, but there are also species from Brazil, Uruguay and Perú. For each species, we bring information on original and valid names, bibliographic references, category of types, sex of the specimens (if it is indicated) and code numbers assigned to them in the MLP entomological collection.
