| Revisão do gênero Antiteuchus Dallas (Heteroptera, Pentatomidae, Discocephalinae). O gênero Antiteuchus Dallas, 1851 com 46 espécies descritas é revisado; as espécies são redescritas com base na morfologia externa da genitália do macho e em algumas características da morfologia geral do corpo. Neodine Kirkaldy, 1909 é considerado sinônimo junior de Antiteuchus. As espécies foram subdivididas em seis grupos aqui propostos: A. amplus, A. supinatus, A. peruensis, A. tesselatus, A. marmoratus e A. mixtus. Oito novas espécies são descritas: A. amapensis sp. nov., A. beckerae sp. nov., A. doesburgi sp. nov., A. exiguus sp. nov., A. ledeburi sp. nov., A. marini sp. nov., A. melanicus sp. nov. and A. similis sp. nov. Nove espécies e uma subespécie são... |

| Revision of the genus Paramecocephala Benvegnú, 1968 (Heteroptera, Pentatomidae). The Neotropical genus Paramecocephala Benvegnú, 1968 is revised based on morphological characters, particularly of the genitalia of both sexes. Formerly monobasic with P. foveata Benvegnú, 1968, type species, the genus received two species recently transferred from Mecocephala Dallas, 1851: M. fusca Haglund, 1868 and M. uruguayensis Pirán, 1970. Five new species are herein described: P. australis Frey-da-Silva & Grazia sp. nov., P. bachmanni Frey-da-Silva & Grazia sp. nov., P. bergrothi Frey-da-Silva & Grazia sp. nov., P. guianensis Frey-da-Silva & Grazia sp. nov. and P. subsolana Frey-da-Silva & Grazia sp. nov.

| Revision of the genus Mecocephala Dallas, 1851 (Heteroptera, Pentatomidae). The genus Mecocephala Dallas, 1851 is revised, and some taxonomic and geographical distribution data are evaluated. The following species are considered to belong to this genus: M. acuminata Dallas, 1851 = M. holmbergi Pirán, 1969 syn. nov., M. curculionoides Pirán, 1959, M. bonariensis sp. nov., M. magna sp. nov., M. maldonadensis sp. nov., and M. zikani sp. nov.; their distribution is restricted to southern Neotropical Region. Other species, formerly placed in Mecocephala, are considered, respectively: M. rubripes Berg, 1894 incertae sedis, M. darwini Kirkaldy, 1909 incertae sedis, M. atra Bergroth, 1914 incertae sedis, Paramecocephala uruguayensis (Pirán, 1970) comb. nov.,... |

| ABSTRACT Despite its important effect on the maintenance of tritrophic interactions among plants, insect herbivores, and ants, there is still a paucity of natural history and basic biology information involving trophobiosis among Heteroptera stink bugs. Here, based on previous observations of a new trophobiotic interaction between Edessa rufomarginata (De Geer, 1773) and Camponotus rufipes (Fabricius, 1775) ants, we describe the chemical profile of the honeydew obtained by Gas Chromatography–Mass Spectrometry. There were mainly three different sugars (trehalose, glucose, and sorbose) within our samples. The extrafloral nectaries of Caryocar brasiliense Camb., the host plant of E. rufomarginata, attracts a wide assemblage of Cerrado ants with varying... |
