RESUMO
The genus Voragocoris Weirauch, 2012 is composed of Voragocoris schuhi Weirauch, 2012 and Voragocoris amrishi Makhan, 2013, previously recorded from Peru and Suriname, respectively. In this paper, a new species, Voragocoris weirauchae sp.n., is described based on specimens collected in the Brazilian Amazon, representing the first record of the genus from Brazil. We provide diagnosis, description, photographs of habitus, and scanning electron micrographs of the diagnostic features. A key to species based on males of Voragocoris is also presented.

Hoplonannus McAtee Maloch, 1925 comprises three species described from Central America. Females of all these species are known only from brachypterous specimens. This paper describes the first South American species of the genus, Hoplonannus australis sp. nov. The new species differs from its congeners, in females, by the submacroptery, presence of ocelli and a basal bulge in the seventh sternite; in males, it differs by the presence of a process in the eighth tergite and the right paramere bifurcate apically, with branches subparallel. These traits entail a new diagnosis for the genus.

Because species diversity of the small true bug family Schizopteridae is greatest in tropical and subtropical areas, it is not surprising that only four species have been described from the United States. As part of a larger project on the taxonomy and phylogenetics of Schizopteridae, 178 specimens from the United States were examined. This material contained representatives of the previously described species Glyptocombussaltator Heidemann, 1906, Corixideamajor McAtee & Malloch, 1925, Nannocorisarenarius Blatchley, 1926, and Schizopterabispina McAtee & Malloch, 1925, but also six undescribed species. These new taxa are described as Glyptocombushalbertae sp. n., Glyptocombussuteri sp. n., Nannocorisanophorus sp. n., Nannocorisbrevipilus sp. n., Schizoptera (Cantharocoris) rileyisp. n., and Schizoptera (Schizoptera) henryisp. n. Habitus images and genitalic illustrations of the previously described and the new species are provided as well as a map showing distribution ranges of these species in the United States and Mexico. To provide a comprehensive treatment of the small genus Glyptocombus Heidemann, 1906, Glyptocombusmexicanus sp. n. is also described that, to our knowledge, occurs only in Mexico, and the female of one additional undescribed Glyptocombus species is documented from Mexico.
RESUMO
The Neotropical biodiversity of the cryptic and tiny minute litter bugs in the family Schizopteridae-although thought to be the best documented tropical fauna of Schizopteridae-is still poorly known. Sixteen species of Schizopteridae have been described from Costa Rica, 13 of which during the past few years, and the last new genus of Schizopteridae from that country was described more than half a century ago. We here describe and document a new monotypic genus of Schizopteridae from Costa Rica, Meganannus n. gen. The new genus belongs to the "Ogeriinae" + Schizopterinae lineage of Schizopteridae and stands out among other litter bugs by the large body size, among other features. We provide habitus photographs and document morphological details using scanning electron, confocal, and light compound microscopic images. A map and measurements are also produced. An illustrated identification key to genus groups and/or genera of Neotropical Schizopteridae including this new genus is presented.
