“…In this context, and taking into account the recommendation 72F of the International Code of Zoological Nomenclature (ICZN, fourth edition, January 1999) about the role of collections in making the types available to researches, catalogues have been published aiming to list all Hymenoptera types specimens deposited in the MZUSP collection. These catalogues cover, until this moment: ants (Brandão, 1991;Klingenberg & Brandão, 2005;Brandão et al, 2010;Esteves et al, 2011;Prado & Brandão, 2013;Ulysséa & Brandão, 2013;Ulysséa et al, 2015), bees (Ramos et al, 2015), "Symphyta" & "Parasitica" wasps (Onody et al, 2014), Chrysidoidea (Santos et al, 2017) and Pompiloidea, Thynnoidea and Vespoidea wasps (Andrade et al, 2018). The most recent ones include also images of the primary types to avoid long distance loans and unnecessary movement of these specimens.…”
