RESUMO
Euschistus Dallas is distributed throughout the Western Hemisphere and is composed of 67 species in three subgenera: Euschistomorphus Jensen-Haarup, Lycipta Stl, and the nominate subgenus. Euschistus (Euschistus) includes several economically important species. Due to the lack of a phylogenetic analysis for the subgenus Euschistus, its groupings are based primarily on male genitalia. In this paper, the following Nearctic taxa that were first grouped together by Stl (1872), namely E. ictericus (Linnaeus), E. variolarius (Palisot de Beauvois), E. servus servus (Say), E. servus euschistoides (Vollenhoven), and E. tristigmus tristigmus (Say), are reviewed and redescribed. Several other similar, and probably related, taxa are also included in this study: E. tristigmus luridus (Dallas), E. inflatus Van Duzee, and E. latimarginatus Zimmer. Morphological patterns pertaining to the internal and external male and female genitalia allowed us to formalize the ictericus group to include the above-mentioned species (except E. tristigmus). The morphological overlap between the subspecies and sympatric areas of distribution have led us to consider E. servus euschistoides as a junior synonym of E. servus servus, and to corroborate the synonymy first proposed by Uhler (1861) of E. tristigmus luridus under E. tristigmus tristigmus.

The species of Pentatomidae known to occur north of Mexico, comprising 223 species in 68 genera, are enumerated with taxonomic notes and updated and annotated distributions. Included in this update are 126 new state records reported for 62 pentatomid species in 30 genera. The copious annotations in these distributions and attendant bibliography serve as an extensive compilation of overlooked references that might contain distributional records for other insect, especially heteropteran, species.

Two new species of Tingidae are described from Panama: Acanthotingis deltoides sp. nov. and Stephanitis joceliae sp. nov. Descriptions and diagnosis for both Acanthotingis Monte and Stephanitis Stål are provided, and a key is given for the separation of the two known species of Acanthotingis. This is the first record of both genera from Panama. A checklist of all Neotropical species of both genera is presented.

The genus Acrophyma Bergroth currently contains two species, the Andean A. cumingii (Westwood) and the Neotropical A. bicallosa (Stål). The examination of types and new material revealed that among the Neotropical species the Brazilian population differs from the Colombian, and the first one belongs to a new species in this group. A morphological analysis of the genus indicated the Neotropical species are different from the Andean species. According to the current most used generic characters in acanthosomatids, Neotropical species should be placed in a new genus. This is also supported by biogeographical relationships. New distributional records for the species of this group are provided.

Sibaria Stål is a genus of Pentatomidae occurring exclusively in the Neotropical region. Since its description, little information has been added to the knowledge of the taxon. The hypothesis of monophyly of Sibaria was recently supported by a phylogenetic analysis based on morphological and molecular data. The purpose of this study is to provide a review of Sibaria, redescribe the valid species, and describe a new species. The genus includes four species: S. andicola Breddin, S. armata (Dallas), S. englemani Rolston, and S. amazonica sp. nov.. Diagnoses, macrophotographs (habitus, external and internal genitalia), an identification key, and distribution records of the species are also provided.

Kaytuesso flavolateralis gen. and sp. nov. is described from Papua New Guinea. The new genus is remarkable in that the only included species is one of the smallest species known within the Oncomerinae. The relationships among Kaytuesso and the related genera Agapophyta Guerin, Erga Walker and Musgraveia Leston and Scudder are discussed.

The Aeptini (Pentatomidae: Pentatominae) genus Menestheus Stål, 1868, is redescribed. The original misidentification of the type species for Menestheus is corrected by action of first reviser herein by establishing Paramenestheus nercivus non Dallas, 1851 sensu Stal (1868) = Menestheus cuneatus Distant, 1899 as the type species. Menestheus mcphersoni sp. nov. is described and illustrated. Characters separating the two species are discussed.

In accordance with the rules in the International Code of Zoological Nomenclature, the type species for the genus Edessa Fabricius, 1803 is now recognized to be Cimex antilope Fabricius, 1798 rather than the previously recognized Cimex cervus Fabricius, 1787. Edessa antilope is redescribed, as well as the following four species that have in the past been related or compared to E. antilope: E. arabs (Linnaeus, 1758) from French Guiana, Costa Rica and Panama (new record), E. helix Erichson, 1848 from Costa Rica, Panama, Venezuela, Suriname (new record), Guyana, Brazil (new record), Bolivia (new record) and Argentina (new record), E. ibex Breddin, 1903 from Costa Rica, Panama (new record), Ecuador, Brazil (new record), Peru and Bolivia (new record), and E. taurina Stål, 1862 from Mexico, Guatemala, Belize (new record), Honduras (new record). The distribution of Edessa antilope is expanded to Venezuela. The female of E. antilope and the male of E. taurina are described for the first time. Edessa antilope is removed from the synonymy of E. arabs and reinstated as valid species; additionally, E. costalis Stål, 1872 is removed from the synonym of E. helix and is placed as a junior synonym of E. antilope. Edessa saiga Breddin, 1903 is considered a junior synonym of E. ibex. Lectotypes are designated for all species. A key is provided for the identification of the species.
