The Renodaeus group, a monophyletic assemblage of genera within the New World orthotyline tribe Ceratocapsini, comprising eight genera, including four new ones, is defined; and 48 species are treated, including 26 described as new and 12 transferred from Ceratocapsus Reuter as new combinations. Ceratocapsidea gen. n. is described to accommodate the new species C. bahamaensis sp. n., from the Bahamas; C. baranowskii sp. n., from Jamaica; C. dominicanensis sp. n., from the Dominican Republic; C. rileyi sp. n., from Texas; C. taeniola sp. n., from Jamaica; C. texensis sp. n., from Texas; C. transversa sp. n., from Mexico (Neuvo León); and C. variabilis sp. n., from Jamaica; and Ceratocapsus balli Knight, comb. n., C. complicatus Knight, comb. n., C. consimilis Reuter, comb. n., C. fusiformis Van Duzee, comb. n. (as the type species of the genus), C. nigropiceus Reuter, comb. n., and C. rufistigmus Blatchley, comb. n. [and a neotype designated], Ceratocapsus clavicornis Knight, syn. n. and C. divaricatus Knight, syn. n. are treated as junior synonyms of Ceratocapsus fusiformis Van Duzee. The genus Marininocoris Carvalho and the only included species M. myrmecoides Carvalho are redescribed. The genus Pilophoropsis Poppius is redescribed and revised, Renodaeus texanus Knight, comb. n. is transferred into it and the three new species P. bejeanae sp. n., from Sonora, Mexico; P. cunealis sp. n., from Oaxaca, Mexico; P. quercicola sp. n., from Arizona, USA, are described. Pilophoropsidea gen. n. is described to accommodate the 12 new species P. brailovskyi sp. n., from Federal District, Mexico; P. cuneata sp. n., from Chiapas, Mexico; P. dimidiata sp. n., from Durango, Mexico; P. fuscata sp. n., from Durango, Mexico and Arizona and New Mexico, USA; P. keltoni sp. n., from Durango, Mexico; P. maxima sp. n., from Durango, Mexico; P. pueblaensis sp. n., from Puebla, Mexico; P. schaffneri sp. n., from Neuvo León and San Luis Potosi, Mexico; P. serrata sp. n., from Michoacan, Mexico; P. touchetae sp. n., from Mexico (Puebla); P. truncata sp. n., from Mexico (Guerrero); P. tuberculata sp. n., from Mexico (Guerrero); and Ceratocapsus barberi Knight, comb. n., Ceratocapsus camelus Knight, comb. n. (as the type species of the genus), and Ceratocapsus fascipennis Knight, comb. n. Pilophoropsita gen. n. is described to accommodate P. schaffneri sp. n. from Costa Rica and Mexico (Jalisco, Nayarit, Oaxaca). The genus Renodaeus Distant is redescribed and the new species R. mimeticus sp. n. from Ecuador is described. The genus Zanchisme Kirkaldy is reviewed and the four known species are redescribed. Zanchismeopsidea gen. n. is described to accommodate Z. diegoi sp. n. from Argentina (Santiago del Estero). Provided are habitus illustrations for certain adults (Pilophoropsidea camelus, Pilophoropsis brachyptera Poppius, Renodaeus mimeticus, and Zanchisme mexicanus Carvalho & Schaffner), male and female (when available) color digital images and figures of male genitalia of all species, electron photomicrographs of diagnostic characters for selected species, and keys to the genera and their included species. The taxa treated in this paper are arranged alphabetically by genus and species.
