Some Neotropical Lepturini are studied: Euryptera latipennis Audinet-Serville, 1828 (type species) redescription, Strangalia dimidiate (Redtenbacher, 1868) new combination (= Strangalia melanophthisis (Berg, 1889) new combination, new synonymy, and lectotype designation), Strangalia fulvicornis (bates, 1872), new record from Argentina; Strangalia melanùra (Redtenbacher, 1868) new combination from Brazil; Strangalia rubricollis (Bates, 1870) new record from Peru. “Leptura” bonariensis Burmeister , 1865 is not a true Leptura, being exotic for Argentina and for the Neotropical fauna; the type-specimen was mislabeled as coming from Buenos Aires. Elytral patterns, posterior tarsi, antennae, 5th apparent urosternite, and elytral apices of E. lapipennis, and S. dimidiate are illustrated. A key to Argentinian genera and species is provided.
This revision of the Neotropical predaceous midges of the genus Brachypogon (Brachypogon) Kieffer, recognizes 18 extant species, including the following 12 new species: Brachypogon (B.) apunctipennis, bifidus, bimaculatus, ecuadorensis, ethelae, insularis, monicae, pseudoparaensis, schmitzi, spatuliformis, telesfordi, and woodruffi. Two species groups are recognized, the fuscivenosus and impar groups. The hitherto unknown male of B. paraensis Wirth & Blanton is described and illustrated, and the female of that species as well as both sexes of B. impar (Johannsen) and B. fuscivenosus (Lutz) are redescribed and illustrated. Diagnoses are provided for previously described species, as well as a key for the recognition of all Neotropical species. New records of B. impar are from Brazil, Colombia, and Argentina.
Se rivalida el genero Cubobolus Chamberlin (1918) para Cuba; en el se incluyen algunas especies ubicadas anteriormente en Rhinocricus Karsch (1881) y Anadenobolus Silvestri (1897): Cubobolus sagittatus (Loomis 1938), Cubobolus pertenuis (Loomis 1938), Cubobolus sinuosus (Loomis 1938), y Cubobolus perplicatus (Loomis 1938). Se describen ademas seis nuevas especies: Cubobolus potrerillo, C. escambray, C. dentatus, C.jibacoa, C. monitongo, y C. cuba. Se comenta la exclusion, hasta el momento, de representantes del genero Anadenobolus en la isla de Cuba.
Se describen 5 especies nuevas del generoAmphelictogon para la isla de Cuba, estas son: A. turquinensis,A. blairi, A. loomisi, A. estebani, y A. albertoi. Se presentan los principales caracteres utilizados para la diferenciaci6n de las especies, asi como una clave taxon6mica. Se realizan comentarios sobre la ecologia y biogeografia de este grupo en la isla.
Se analizan las relaciones filogeneticas de las especies del genero americano Poecilopompilus Howard y se contribuye al esclarecimiento de las relaciones filogeneticas con los generos hermanos Austrochares, Batozonellus, Episyron y Sericopompilus; 38 caracteres fueron analizados cladisticamente utilizando el programa para Ms-DOS Pee-Wee (Goloboff, 1993). En el arbol resultante, los generos considerados conforman un grupo monofiletico. El genero BatozonelIus esta mas relacionado filogeneticamente con Poecilopompilus y estos a su vez con Austrochares. Poecilopompilus es un genero monofiletico. Ademas se presenta una clave para la identificaci6n de las 10 especies conocidas de Poecilopompilus e ilustraciones.
Mesolecanium deltae Lizer y Trelles, 1917 y Lecanium perlatum Cockerell, 1898, son conocidas co mo plagas de citrus en Argentina, Brasil, Paraguay, y Uruguay. EI estudio deI materiailleva a la conclusion de que son sinonomos, y que la especie estaria mejor ubicada en el genero Parthenolecanium, por 10 que se propone a Parthenolecanium perlatum (Cockerell) como una nueva combinacion.
Taxonomy, synonymy, distribution, and biologies of Nearctic (and a few Neotropical and Pale arctic) Anthribidae are reviewed, new keys are provided, and four new genera and eleven new species are described. Allandrus Leconte, 1876 (=Tropiderinus Reitter, 1916). Anthribus Geoffrey, 1762 (=Pseudobrachytarsus Pierce, 1930). Araecerus Schoenherr, 1823 (=Araeocorynus Jekel, 1855); Araecerus coffeae Fabricius, 1801 (=Tropideres (Rhaphitropis) mateui Cobos, 1954). Brachycorynus n. gen., type species Tropideres rectus Leconte, 1876; congeneric: Homocloeus distentus Frieser, 1983 from Cuba and Florida, and B. hirsutus n. sp. from Texas. Choragus major n. sp., Ohio, etc., striolatus n. sp., Ohio, and exophthalmus n. sp., Virginia. Corrhecerus Schoenherr, 1826 (=Paranthribus Jordan, 1904) resulting in Corrhecerus rufescens (Jordan, 1904), new combination. Eurymycter Leconte, 1876, and Gonotropis Leconte, 1876, are removed from synonymy with Tropideres Schoenherr, 1823, and returned to full generic rank. Eusphyrus Leconte, 1876 is removed from synonymy with Ormiscus Waterhouse, 1845, and returned to full generic rank; Tropideres (Opisthotropis) vasconicus Hoffmann and Tempere, 1954, from France is transferred to Eusphyrus, with Opisthotropis a generic synonym; Eusphyrus pulicarius Boheman, 1859, Brasil, is transferred from Brachytarsus, and the species eusphyroides Schaeffer and quercus Schaeffer are transferred from Ormiscus. Gymnognathus triangularis n. sp., Texas. Habroxenus n. gen., type species H. politus n. sp., Texas and Maryland, also H. fuscus n. sp., Guatemala, and H. sarmenticola n. sp., Haiti.

Introgressive hybridization is invoked for the Trigonorhinus limbatus-griseus complex. New keys are provided for the species of Brachycorynus, Choragus, Habroxenus, Neoxenus, Phoenicobiella, Trigonorhinus, and Eusphyrus, plus a new key to Nearctic tribes and genera, and a new Nearctic checklist. New distribution and life-history data are given for many species.
Afralampes capensis is described as a new genus and species in the Megalonotini. The systematic position of Serranegra Lindberg is discussed, a new species is described from South Africa and a key to species included. A new species of Diniella Bergroth is described from South Africa and a key to the African species included. A new species of Polycrates Stal is described from South Africa. The immature stages of Polycrates consutus (Germar) are described with notes on its distribution and biology. The first records of the occurrence of species of Lampropunctus Scudder and Lamproceps Reuter from South Africa are included. Wing polymorphism is discussed. Lispolophus Bergroth is reduced to junior synonymy with Diniella. Diniella nitens (Wagner) is reduced to a junior synonym of Diniella laevicollis.
