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 Ceratocapsideabahamaensis sp. n., from the Bahamas; Ceratocapsideabaranowskii sp. n., from Jamaica; Ceratocapsideadominicanensis sp. n., from the Dominican Republic; Ceratocapsidearileyi sp. n., from Texas; Ceratocapsideataeniola sp. n., from Jamaica; Ceratocapsideatexensis sp. n., from Texas; Ceratocapsideatransversa sp. n., from Mexico (Neuvo León); and Ceratocapsideavariabilis sp. n., from Jamaica; and Ceratocapsusballi Knight, comb. n., Ceratocapsuscomplicatus Knight, comb. n., Ceratocapsideaconsimilis Reuter, comb. n., Ceratocapsusfusiformis Van Duzee, comb. n. (as the type species of the genus), Ceratocapsusnigropiceus Reuter, comb. n., and Ceratocapsusrufistigmus Blatchley, comb. n. [and a neotype designated], Ceratocapsusclavicornis Knight, syn. n. and Ceratocapsusdivaricatus Knight, syn. n. are treated as junior synonyms of Ceratocapsusfusiformis Van Duzee. The genus Marininocoris Carvalho and the only included species Marinonicorismyrmecoides Carvalho are redescribed. The genus Pilophoropsis Poppius is redescribed and revised, Renodaeustexanus Knight, comb. n. is transferred into it and the three new species Pilophoropsisbejeanae sp. n., from Sonora, Mexico; Pilophoropsiscunealis sp. n., from Oaxaca, Mexico; Pilophoropsisquercicola sp. n., from Arizona, USA, are described. Pilophoropsidea gen. n. is described to accommodate the 12 new species Pilophoropsideabrailovskyi sp. n., from Federal District, Mexico; Pilophoropsideacuneata sp. n., from Chiapas, Mexico; Pilophoropsideadimidiata sp. n., from Durango, Mexico; Pilophoropsideafuscata sp. n., from Durango, Mexico and Arizona and New Mexico, USA; Pilophoropsideakeltoni sp. n., from Durango, Mexico; Pilophoropsideamaxima sp. n., from Durango, Mexico; Pilophoropsideapueblaensis sp. n., from Puebla, Mexico; Pilophoropsideaschaffneri sp. n., from Neuvo León and San Luis Potosi, Mexico; Pilophoropsideaserrata sp. n., from Michoacan, Mexico; Pilophoropsideatouchetae sp. n., from Mexico (Puebla); Pilophoropsideatruncata sp. n., from Mexico (Guerrero); Pilophoropsideatuberculata sp. n., from Mexico (Guerrero); and Ceratocapsusbarberi Knight, comb. n., Ceratocapsuscamelus Knight, comb. n. (as the type species of the genus), and Ceratocapsusfascipennis Knight, comb. n. Pilophoropsita gen. n. is described to accommodate Pilophoropsideaschaffneri sp. n. from Costa Rica and Mexico (Jalisco, Nayarit, Oaxaca). The genus Renodaeus Distant is redescribed and the new species Renodaeusmimeticus 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 Zanchismeopsideadiegoi sp. n. from Argentina (Santiago del Estero). Provided are habitus illustrations for certain adults (Pilophoropsideacamelus, Pilophoropsisbrachyptera Poppius, Renodaeusmimeticus, and Zanchismemexicanus 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.
