          Abstract

          Abstract Popularly known as "witch ants" or "velvet ants", mutillids are solitary ectoparasitoids wasps of immature insects. Atillum André, 1903, is a genus endemic to South America composed of 49 valid species. This study was motivated by the inconsistency of the available information, where, depending on the consulted bibliography, the number of Atillum species in Brazil varies. This contribution aims to reduce the knowledge gap on this genus, verifying the real number of species that comprise it and which actually inhabit Brazil. The specialized bibliography for Mutillidae and Atillum was consulted, in addition to carrying out an exhaustive consultation of the specialized bibliography. Additionally, to validate some of the records found, Atillum specimens deposited in the main collections that house this group were examined. As a result, records were found for ten Atillum species in Brazil, nine of which were confirmed as present in the country, and unpublished records of presence of Atillum and Atillum bucephalum (Perty, 1833) in four Brazilian states and eight municipalities located in the Northeastern region of the country.

          Resumen Popularmente conocidas como "hormigas-brujas" u "hormigas de terciopelo", los mutílidos son avispas solitarias ectoparasitoides de insectos inmaduros. Atillum André, 1903, es un género endémico de América del Sur compuesto por 49 especies válidas. Este estudio fue motivado por la inconsistencia de la información disponible, donde, dependiendo de la bibliografía consultada, varía el número de especies de Atillum en Brasil. En este aporte se pretende reducir la brecha de conocimento sobre este género, verificando el número real de especies que lo componen y cuales habitan efectivamente en Brasil. Se consultó la bibliografía especializada para Mutillidae y Atillum. Adicionalmente, para validar algunos de los registros encontrados, se examinaron especímenes de Atillum depositados en las principales colecciones que albergan a este grupo. Como resultado, se encontraron registros para diez especies de Atillum en Brasil, nueve de las cuales fueron confirmadas como presentes en el país, y también se entregan registros inéditos de presencia de Atillum y Atillum bucephalum (Perty, 1833) en cuatro estados brasileños y ocho municipios localizados en la región noreste del país.

            Repeated evolution in overlapping mimicry rings among North American velvet ants.

            Müllerian mimicry, in which two or more harmful species share a similar appearance for mutual benefit, is a widely appreciated, yet relatively uncommon natural phenomenon. Although Müllerian mimicry occurs in vertebrates, most studies are focused on tropical, herbivorous invertebrates. Here we identify a large Müllerian mimicry complex in North American velvet ants (Hymenoptera: Mutillidae). These are conspicuous, diurnal parasitoids of bees and wasps that defend themselves with a powerful sting. We investigate morphological and genetic variation and ask whether morphological similarities are the result of convergent evolution or shared ancestry. We find that 65 species in the velvet ant genus Dasymutilla can be placed into one of six morphologically distinct and geographically delimited mimicry rings. Müllerian colour patterns are primarily the result of independent evolution rather than shared, phylogenetic history. These convergent colour syndromes represent one of the largest known Müllerian mimicry complexes yet identified, particularly in the Northern Hemisphere.
