Abstract. Rhynchotermes nasutissimus (Silvestri) is a leaf litter species with Neotropical distribution. We found for the first time this species associated with rat carrion in an urban area of Brasília, Distrito Federal, Brazil. Ten soldiers and 36 workers were spread in the cavities and between internal leathers of the carrion's dry remains of the animal that have been exposed during a week in the soil, in March 2012, at end of the wet season. We believe that this uncommon behavior may reflect a nutritional need.Keywords: Cerrado; Necrophagous insects; Neotropical; Termites. Primeiro Registro de Rhynchotermes nasutissimus (Silvestri) (Isoptera: Syntermitinae) Associado à Carcaça de Rato em Brasília, BrasilResumo. Rhynchotermes nasutissimus (Silvestri) é uma espécie que se alimenta de folhas de serrapilheira e que possui distribuição Neotropical. Encontrou-se pela primeira vez esta espécie associada com carcaça de rato, em uma área urbana de Brasília, Distrito Federal, Brasil. Os dez soldados e 36 operários se encontravam dispersos entre as vértebras e restos secos do animal que foi exposto durante uma semana no solo em março de 2012, final da estação chuvosa. Acredita-se que este comportamento raro seja resultado de alguma deficiência nutricional.

Giant (Myrmecophaga tridactyla) and collared anteaters (Tamandua tetradactyla) are common mammals in the Cerrado biome. They are specialized in eating termites (Isoptera, Blattaria) and ants (Formicidae, Hymenoptera). This study tested the preference of the giant anteater for termites with different defense strategies: 1) soldier with chemical defense and a soft nest (Nasutitermes), and 2) soldier with mixed defenses-chemical and mechanical-and a hard nest (Cornitermes). Pieces of nests of both genera of termites were provided to captive giant anteaters, their behaviors were observed, and the time spent feeding in each termite nests was recorded. The anteaters exploited both termite species, although no significance difference was found, they spent more time feeding on Cornitermes than on Nasutitermes. The stomach contents of one road-killed giant anteater and one collared anteater were analyzed. The collared anteater fed on a wider diversity of termite species with different defense strategies, but showed a preference for Cornitermes. We argue that the preference of anteaters for a termite species that has a harder nest, and soldiers with mixed defense, may be due to the presence of terpenoids in the chemical apparatus of Nasutitermes, absent in Cornitermes. Also, the much higher proportion of soldiers in Nasutitermes may influence the anteaters' choice.

ABSTRACT. Checklist of species of Ropalomeridae, Sphaeroceridae and Ulidiidae (Diptera, Acalyptratae) of the state of Mato Grosso do Sul, Brazil. In this paper it is provided a checklist of the Ropalomeridae, Sphaeroceridae and Ulidiidae species registered in the state of Mato Grosso do Sul, Brazil. The Ropalomeridae is represented by eight species distributed in four genera: Dactylissa Fischer (1), Kroeberia Lindner (1), Ropalomera Wiedemann (5) and Willistoniella Mik (1). A single species of Sphaeroceridae is recorded for the state: Neosphaerocera fl avicoxa (Malloch, 1925), as well as of Ulidiidae: Notogramma cimiciforme Loew, 1868.
