| Abstract | A systematic study of the subfamily Dicyphinae Reuter (Heteroptera: Hiridae) resulted in a redefinition of the subfamily and included genera) and a revision of the genus Dicyphus Fieber in the Western Hemisphere. The study entailed examination of about 14,000 specimens, including numerous noudicyphine, cimicomorphan taxa to assess character transformations. New character sources, such as the thoracic pleura, were investigated to test current classifications, establish the present classification, and perform a preliminary phylogenetic analysis with included consideration of host associations and biogeography. In the first chapter, general information about the family Hiridae is given and the systematic problems of the Dicyphinae and the objectives of the study are elucidated. In the second chapter, a diagnosis of the subfamily is provided with some discussion of the intrafamilial relationships. Also the genera of the subfamily are redefined, redescribed, and included species for each genus are listed. Sixteen genera are recognized and one new genus, Glarisia n. gen., and one new subgenus, Uhlerella n. sgen., of the genus Dicyphus, are described. The six subgenera of Cyrtoeltis Fieber: Cyrtopeltis, Engytatus Reuter, Nesidocoris Kirkaldy, Singhaiesia China and Carvaiho, Tupiocoris China and Carvalho, and Usingerella China and Carvalho are elevated to generic rank, whereas the subgenera of Dicypbus are retained. Chapter three is a revision of the genus Dicyphus in the Western Hemisphere which contains nine species. There are eight endemic species belonging to the endemic subgenus D. (Uhlerella), including two new species nigracorium n. sp. and occidentalis n. sp.. A key is given to the species. |
