Synonymies, new combinations, new status, revalidations, and generic transfers are presented for Western Hemisphere Cerambycidae. In the subfamily Prioninae, taxa are in the tribes Macrodontiini and Mallaspidini; in the subfamily Cerambycinae in the tribesCerambycini, Elaphidiini, Molorchini, Rhinotragini, Compsocerini, Callidiini, Clytini, Cleomenini, Heteropsini and Trachyderini; and in the subfamily Lamiinae in the tribes Pannenini, Lamiini, Onciderini, Pteropliini, Pogonocherini, Desmiphorini, Acanthoderini, Acanthocinini, Aerenicini and Calluni.
The fauna of Curculionoidea (exclusive of the subfamilies Scolytinae and Platypodinae of the Curculionidae) is surveyed for Dade and Monroe Counties in southern Florida. Numbers of genera and species represented are as follows: Anthribidae (12 genera, 22 species), Belidae (1 genus, 2 species), Attelabidae (3 genera, 3 species), Brentidae (6 genera, 14 species) and Curculionidae (115 genera, 249 species). No Nemonychidae are recorded from southern Florida. Included in the totals are 26 species considered as introduced to the region and 5 species likely not established in the region. Twenty apparently undescribed species are recorded. Fifteen are assignable to genera as follows; Ormiscus (2) (Anthribidae), and Podapion (1) (Brentidae), and Prosaldius (1), Acalles (6), Calles (1), Zascelis (1), Notolomus (1), Lixus (1), and Conotmchelus (1) (Curculionidae). The generic placement of 5 undescribed species of Curculionidae is uncertain and descriptions of new genera may be required. New generic records for the United States of America are Homocloeus Jordan (Anthribidae), and Stenotrupis Wollaston (Curculionidae; Cossoninae) and Heilus Kuschel (Curculionidae; Curculioninae). New species records for the United States are Homocloeus distentm Frieser and Homochw sexverrucatm (Suffrian) (Anthribidae) and Stenotrupis acicula Wollaston, Caulophilus rufotestuceus (Champion), Minominus minimus (Boheman) (Curculionidae; Cossoninae), and Anthonomus rubricosus Boheman and Heilus bioculatus (Boheman) (Curculionidae; Curculioninae). Particularly well-represented in terms of species diversity is the anthribid genus Ormiscus (6), the brentid genus Apion (9) and the curculionid genera Listronotus (21), Anthonomus (14), Acalles (13), Conotrachelus (11), Tyloderma (10) and Sphenophorus (10).
The names of previously described South American species of Oxybelus are listed, annotated, and synonymy given. Nomenclature changes are: brethesi is a new name for interruptus Brethes 1913; decipiens Brethes 1913 and pamparum Brethes 1913 are synonyms of catamarcensis Schmttky 1909; fritzi is a new name for modestus Brethes 1913; agnitus Brethes 1913 is a synonym of marginatus F. Smith 1866; joergenseni Brethes 1913 is a synonym of paraguayensis Brethes 1909; and tarijensis Brethes 1913 is a synonym of platensis Brethes 1901. Neotypes are established for platensis and catamarcensis, and lectotypes for americanus, argentinus, modestus, marginatus, and tarijensis.
The New World species formerly placed in Borborillus Duda (Sphaeroceridae: Copromyzinae) are transfemdto Norrbomia Papp. These are: N. lacteipennis (Malloch), n. comb., N. fumipennis (Stenhammar), n. comb., N. frigipennis (Spuler), n. comb., N. scripta (Malloch), n. comb., and N. sordida (Zetteretedt). Norrbomia fulvipennis, N. singusta, N. mexicana, N. triglabra, and N. yukonensis are described as new. Borborus articus Malloch is synonymized with N. fumipennis, and Borborus singularis Spuler is synonymized with N. scripta. All ten New World species of Norrbomia are keyed, illustrated and described. Their relationships are discussed and a cladogram is provided. Species in two of the defined clades are kleptoparasitic on dung rolling scarab beetles.
Males of Neohermes concolor (Davis) from the interior highlands of Arkansas, Oklahoma, and Missouri, and from Illinois, Indiana, and Kentucky exhibited considerable variation in male terminalia. Differences occurred in the size of the dorsal membrane of the ninth sternite and in the shape of the tenth tergite (anal plate) which varied from rounded to truncate-shaped. This observed variation does not appear to be geographically correlated. Females of N. concolor did not exhibit broad variation in terminalii. Little variation was observed among males of N. angusticollis (Hagen) and N. matheri Flint. The broad range of variation observed in the tenninalia of N. concolor could result in misidentification by collectors who rely only on the shape of the anal plate rather than the more constant shape of the aedeagus.
The following new species are described: Lydipta humeralis, sp. n. and Cacostola obliquata, sp. n., from Ecuador; Lochmaeocles leuripennis, sp. n., and Carenesycha velezi, sp. it., from Colombia; Oltcideres marauara, sp. it., from Brazil (Amazonas). Oncideres minuta Thomson, 1865, is recorded from Ecuador.
A specimen of Rhizophagus sayi Schaeffer collected in a flight trap at 29°34½'N82°29'W in Alachua County, Florida, on 23-1-1993, by R.W. Lundgren prompted a search of unidentified specimens in the Florida State Collection of Arthropods. The search resulted in the discovery of seven additional Florida specimens with the following data: "FLA., Dixie Co. 3.5mi. N. Old Town 13-1-1980 Coll. M.C. Thomas", 2; "FLORIDA: Alachua Co. Gainesville 3-XII-1983 Coll. M.C. Thomas", 1; "FLORIDA: Alachua Co. San Felasco Hammock 4-11-1983 M.C. Thomasn, 3; same, except date is 12-II-1983. These specimens comprise a new state record for R. sayi, which Bousquet (1990) recorded from most of the eastern United States except for Florida and Georgia.
