Interpretive Summary: Plant bugs represent the largest family of true bugs and include numerous agriculturally important species. Many are serious crop pests, causing enormous economic losses in the United States annually. In addition, a large number of these bugs are valuable predators of various arthropods, such as lepidopteran eggs and larva, aphids, mites, and scale insects, making them of considerable interest to researchers involved in biocontrol. This paper provides a revision of a group of plant bugs that are largely predatory. Many of the bugs in this complex of genera are remarkable in their resemblance to ants, which affords them protection against larger visual predators. In this paper, seven plant bug genera, four of which are described as new to science, and 48 species, 26 of which are described as new to science, are presented. Color photographs of all adults and an identification key is provided to aid in species recognition. This information will be of interest to a wide range of researchers and regulatory personnel in Federal and state departments of agriculture working in insect pest management and biocontrol of crop pests.

Technical Abstract: The Renodaeus group, a monophyletic composition 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 as new combinations transferred from Ceratocapsus Reuter. The genus Ceratocapsidea, n. gen. is described to accommodate the new species C. bahamaensis, n. sp., from the Bahamas; C. baranowskii, n. sp., from Jamaica; C. dominicanensis, n. sp., from the Dominican Republic; C. rileyi, n. sp., from Texas; C. taeniola, n. sp., from Jamaica; C. texanensis, n. sp., from Texas; C. transversa, n. sp., from Mexico (Neuvo Leon); and C. variabilis, n. sp., from Jamaica; and Ceratocapsus balli Knight, n. comb., C. fusiformis Van Duzee, n. comb. (as the type species of the genus), C. complicatus Knight, n. comb., C. consimilis Reuter, n. comb., C. nigropiceus Reuter, n. comb., and C. rufistigmus Blatchley, n. comb. Ceratocapsus divaricatus Knight, n. syn. and C. clavicornis Knight, n. syn. 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, n. comb. is transferred into it and the three new species P. bejeanae, n. sp., from Sonora, Mexico; P. cunealis, n. sp., from Oaxaca, Mexico; P. quercicola, n. sp., from Arizona, USA, are described. The genus Pilophoropsidea, n. gen. is described to accommodate the 12 new species P. brailovskyi, n. sp., from Federal District, Mexico; P. cuneata, n. sp., from Chiapas, Mexico; P. dimidiata, n. sp., from Durango, Mexico; P. fuscata, n. sp., Durango, Mexico and Arizona and New Mexico, USA; P. keltoni, n. sp., from Durango, Mexico; P. maxima, n. sp., from Durango, Mexico; P. pueblaensis, n. sp., from Puebla, Mexico; P. schaffneri, n. sp., from Neuvo Leon and San Mexico, Luis Potosi; P. serrata, n. sp., from Michoacan, Mexico; P. touchetae, n. sp., from Mexico (Puebla); P. truncata, n. sp., from Mexico (Guerrero); P. tuberculata, n. sp., from Mexico (Guerrero); and Ceratocapsus barberi Knight, n. comb., Ceratocapsus fascipennis Knight, n. comb., and Ceratocapsus camelus Knight, n. comb. (as the type species of the genus). The genus Pilophoropsita, n. gen. is described to accommodate, P. schaffneri, n. sp. from Costa Rica and Mexico (Jalisco, Nayarit, Oaxaca). The genus Renodaeus Distant is redescribed and the new species R. mimeticus, n. sp. from Ecuador is described. The genus Zanchisme Kirkaldy is reviewed and the four known species are redescribed. The genus Zanchismeopsidea, n. gen. is described to accommodate Z. diegoi, n. sp. from Argentina (Santiago del Estero). Provided are habitus illustrations for certain adults (Pilophoropsidea camelus, Pilophoropsis brachyptera, Renodaeus mimeticus, and Z. mexicanus Carvalho and 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 inthe paper are arranged alphabetically by genus and species.
