Abstract Anisopodus subarmatusMelzer, 1931 is synonymized with A. jaculus (Gyllenhal, 1817) and a discussion about the type-locality of the latter is provided. Photographs of the lectotype of the former and of the holotype of the latter are provided.

Abstract The validity of two forgotten names, EryphusKlug, 1829 and E. rubricollisKlug, 1829, is discussed. The former is considered a nomen oblitum and synonymized with EriphusAudinet-Serville, 1834, a nomen protectum; the latter is revalidated and Eriphus purpuratus Chevrolat, 1862 is considered a junior synonym of Eriphus rubricollis (Klug, 1829). A lectotype is designated to Eryphus rubricollisKlug, 1829. The date of the work where EriphusAudinet-Serville, 1834 was described is corrected. A new genus is described in Dichophyiini Gistel, 1848 to include the species currently allocated in Eryphus sensuNapp & Martins (2002). The dates of publication of genera and species described by Fairmaire & Germain (Révision des Coléoptères du Chili (suite)) are corrected.

Abstract Twenty three new state records of Cerambycidae are provided for Espírito Santo State, Brazil. Forgotten geographical records for Desmiphora (Desmiphora) cirrosa Erichson, 1847, and Cipriscola fasciata (Thomson, 1860) are mentioned. Notes on Metacriodion capixaba Fragoso, 1970, Potiaete maculata Martins & Galileo, 1999, and Eriphus mexicanus Audinet-Serville, 1834 are presented. The female of Trestonia griseaMartins & Galileo, 1990 is described for the first time. Stenoeme annularisMartins, 1980 is redescribed and a key to species of Stenoeme is provided. Four new species are described from the Brazilian state of Espírito Santo: Microibidion fiuzai, Iquiracetima venturai, Adesmus culiki, and Xenofrea simplicioi.

Abstract We studied 18 cerambycid beetle species native to South America. Seventeen represent new state records in Brazil. Particularly, Chlorethe scabrosaZajciw, 1963 is newly reported for the state of Rio de Janeiro with exclusion of C. brachypteraZajciw, 1963. The Brazilian state of the type locality of Dufauxia guaicurana Lane, 1955 is fixed. Pirangoclytus mendosus (Galileo & Martins, 1996) is synonymized with P. mniszechii (Chevrolat, 1862), and its holotype is a female. Variation on Trypanidius maculatus Monné & Delfino, 1980 is commented. New country and department records for Paraguay are also provided.

Abstract The mating behavior of M. angulata (Fabricius, 1775) is described, illustrated and discussed. Additionally, we also comment on the possible new host plant of this species based on two plants (Luehea cymulosa Spruce ex Benth. (Malvaceae) and Doliocarpus dentatus (Aubl.) Standl (Dilleniaceae) on which copulation occurs.

Abstract In this study, two new genera of Desmiphorini (Lamiinae) are proposed: Cleidaria gen. nov., to include Cleidaria cleidae sp. nov. from the state of Chiapas in Mexico, and Obscenoides gen. nov. for Desmiphora (D.) comptaMartins & Galileo, 2005. The shape of tarsal claws of Cleidaria cleidae sp. nov. (abruptly narrowed from basal half) is so far, not found in any current genera of the tribe. With respect to Obscenoides compta (Martins & Galileo, 2005) comb. nov., the genitalia of males have an unusual shape with non-retractile parameres. The character combination related to this genital structure is unknown to us in other species in the family, and hypotheses about its function are suggested.

Abstract Two new species of Elaphidiini from Colombia are described: Sphaerion costae sp. nov., and Mephritus costae sp. nov. The keys to species of Sphaerion Audinet-Serville, 1834 and Mephritus Pascoe, 1866 are translated and modified to include the new species. Chromatic variations of Mephritus apicatus (Linsley, 1935) are reported. Moreover, the geographical distribution is expanded for 12 species of Elaphidiini.

Abstract Oxylopsebus Clarke, 2008 is considered as a junior synonym of Oxycoleus Lacordaire, 1868. Equescollum is proposed as a new genus for E. birai sp. nov. from Costa Rica, which is described and illustrated.

ABSTRACT Three new species and one new genus are described: Psyrassa lisitskyi sp. nov., from Peru (Elaphidiini); Ophtalmibidion antonkozlovi sp. nov., from Colombia (Neoibidionini); and Nappella gen. nov., is proposed to N. antonkozlovi sp. nov., from Peru (Calliini). Epectasis mexicana Breuning, 1954 is redescribed, and figured for the first time, and recorded for Colombia. Psyrassa lisitskyi is included in a modified couplet from a previous key. A key to species of Ophtalmibidion and genera of Calliini are provided. Chorenta biramiguelus is recorded for Peru.

Abstract The genus Jupoata is redescribed and Jupoata antonkozlovi, a new species from Costa Rica is described. An updated key to species of the genus and a new geographical record are provided.

Abstract Based on material recently collected in Peru (Loreto department) the female of Poeciloxestia plagiata (Waterhouse, 1880), and the male of Iuati spinithorax Martins & Galileo, 2010 are described and figured for the first time. Both species are recorded for the first time from Peru.

Abstract Glyptoscapus letiziae, a new species of Hexoplonini Martins, 2006, is described from Brazil (Minas Gerais). Glyptoscapus cicatricosus Aurivillius, 1899 and G. vanettii Martins, 1959 are synonymized with G. pallidulus (White, 1855). A key to species of Glyptoscapus is provided. New state records are presented for Thoracibidion io (Thomson, 1867) (Neoibidionini), Coleoxestia rafaeli Santos-Silva & Wappes, 2017 and C. denticornis (Gahan, 1892) (Cerambycini). The female of C. rafaeli is described for the first time.
