Synopsis of Schizopteridae (Hemiptera, Heteroptera, Dipsocoromorpha) from the United States, with description of seven new species from the US and Mexico

Abstract

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 Glyptocombus saltator Heidemann, 1906, Corixidea major McAtee & Malloch, 1925, Nannocoris arenarius Blatchley, 1926, and Schizoptera bispina McAtee & Malloch, 1925, but also six undescribed species. These new taxa are described as Glyptocombus halbertae sp. n., Glyptocombus suteri sp. n., Nannocoris anophorus sp. n., Nannocoris brevipilus sp. n., Schizoptera (Cantharocoris) rileyi sp. n., and Schizoptera (Schizoptera) henryi sp. 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, Glyptocombus mexicanus 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.
