Diagnostic characters of the first antennal segment, posterolateral margins of the pronotum, expansion of the humeri and humeral angles, outer dilations of the hind tibiae, and coloration patterns are given. Images of dorsal habitus, hind leg, male genital capsule, and parameres of the new species are provided. [ABSTRACT FROM AUTHOR]

Two species of Acanthocephalini are described, Ichilocoris carpinteroi Brailovsky, new species from Argentina and Salapia morenoi Brailovsky, new species from Peru. Color dorsal habitus images of each species are included. A key to the species of Ichilocoris is given. [ABSTRACT FROM AUTHOR]

Four monotypic genera, and the species belonging to each genus – Arioge germainii (Signoret), Eretmophora protensa Stein, Rochrosoma subaptera Reed, and Stiroptus lineaticornis Stål – are redescribed, and one new genus and one new species from Colombia are described in the tribe Coreini. Photographs and drawings of the adults and male genitalia and new distributional records to the redescribed species are given, and a lectotype for Eldarca germainii Signoret is designated.

Two new genera, Parypheroides new genus, and Sundarellus new genus, and two new species, Anasa albicans new species, from Argentina, and Sundarellus tiputinus new species, from Ecuador are described. Parypheroides is used to accomodate a species previously included in the binomen Paryphes imperialisStål, 1859. Photographs of the dorsal and ventral habitus, a close up of the head and pronotum, genital capsule and parameres of some species are included. [ABSTRACT FROM AUTHOR]

One new genus and one new species from Bolivia are described in the tribe Acanthocephalini (Coreidae). Photographs of the adult, the parameres, and male genital capsule are provided. Diagnostic information is given to distinguish Bermejanus bifidus from other genera and species of Acanthocephalini. A list of the genera included in the tribe is given. [ABSTRACT FROM AUTHOR]

Abstract. The New World lace bugs (Tingidae) Acalypta emarginata, n. sp., from Guatemala, and Cervantestingis galeata, n. gen. and n. sp., from Veracruz, Mexico, are diagnosed, described, and illustrated. The discovery of Acalypta emarginata in Central America represents one of the southern-most hemisphere records for a species of this largely temperate, moss-feeding genus of Tingidae. The relationship of C. galeata with species of Acalypta are discussed. [ABSTRACT FROM AUTHOR]

Neoquintius aracelianus new species, from Ecuador and Stentoquintius hasselinus new species, from Venezuela are described in the tribe Nematopodini (Coreidae); both are compared with the related species. Dorsal habitus photos, and drawings of male genital capsule are included. Keys to the known species of each genera are included. [ABSTRACT FROM AUTHOR]

Two new genera of Ozophorini (Lygaeoidea) are described, each containing a single new species: Cryptotrophora limonensis from Costa Rica, and Neolonginischus bocononus from Venezuela. Dorsal habitus for each are illustrated and photographed, and drawings of the male genital capsule and paramere of C. limonensis are provided. [ABSTRACT FROM AUTHOR]

The article discusses a research study on Neaplax baja which belongs to the family of Oxycarenidae and described as the second member of the genus from Mexico. An overview of the distributional records for Neaplax mexicana Slater is given as well as the six general recorded from the Western Hemisphere, including Anomaloptera Amyot and Serville, the monotypic genus Notocoderus Henry and Dellapé and Palearctic genus Oxycarenus Fieber. Also provided are an illustration of the new and known species.

The article presents a study on Euagona, a spartocerine coreid genus. It mentions that the species are collected from Bolivia and Peru in which each species is measured in millimeters. It discusses the characteristics of the species including its body length and shape, color, and structure. Results indicate that there are varieties of Euagona including the Euagona. Dallas, Euagona hamata Brailovsky, and Euagona juno Distant.

The article describes the new species Malvanaioides decorata and Malvanaioides galvina, key to the known Malvanaioides species from Brazil. It cites several classifications of the coreid genus Malvanaioides Brailovsky 1990 including M. flavolineata Brailovsky 1993, M. intricata Brailovsky 1990, and M. luridus Brailovsky 1995. An image depicting the dorsal view of a male Malvanaioides decorata is also presented.

The article describes a second species of the genus Meluchopetalops Breddin 1903 in South America. It notes that Meluchopetalops nigrolineatus assigned to the coreid tribe Acanthocephalini is classified from Colombia, Venezuela and Suriname as the second member of the genus. It outlines the new distributional records for Meluchopetalops banausus Breddin. Moreover, it provides an illustration of the new species Meluchopetalops nigrolineatus.

The article discusses the study of the three species of Anasa Amyot and Serville, commonly known as Heteroptera / Coreidae from the common group of coreid bugs from South America. It describes the species Anasa byssoidecerus from Peru, Anasa rapax and Anasa onorei from Ecuador. It includes several illustrations and drawings of the pronotum, male genitalia and paramere.
