Revision of the New World Plant Bug Genus Cyrtocapsus (Heteroptera: Miridae: Bryocorinae: Eccritotarsini), with New and Revised Synonymies, Lectotype Designations, and Descriptions of 12 New Species.

The New World eccritotarsine genus Cyrtocapsus Reuter (Miridae: Bryocorinae) is revised. Cyrtocapsus andinus Carvalho, 1954, n. syn. is synonymized as a junior synonym of Capsus caligineus Stl, 1859; Pirithous pallipes Distant, 1884, is resurrected from synonymy as the next available name for C. caligineus of authors; Miccus elutipes Bergroth, 1910, is resurrected from synonymy as the next available name for C. femoralis of authors and is considered the senior synonym of C. nanus Carvalho, 1954, n. syn.; C. xinguanus Carvalho, 1985, n. syn. is synonymized as a junior synonym of C. intermedius Reuter, 1909; the identities of C. caligineus and C. femoralis Reuter are clarified; lectotypes are designated for five species (Capsus caligineus, Cyrtocapsus femoralis, Cyrtocapsus intermedius, Cyrtocapsus rostratus Reuter, 1908, and Miccus elutipes); and 12 new species are described: C. apicalis, n. sp.; C. atrametatibialis, n. sp.; C. costatus, n. sp.; C. discalis, n. sp.; C. fiuzai, n. sp.; C. glabratus, n. sp.; C. lazelli, n. sp.; C. mesoamericanus, n. sp.; C. metafemoratus, n. sp.; C. schaffneri, n. sp., C. spatulatus, n. sp., and C. suturalis, n. sp. A color dorsal illustration of the adult male and SEM micrographs of C. lazelli, color habitus images of all species, and male genitalia for 19 species are provided, and a revised identification key to the 25 known species of the genus is given to facilitate identification.
