Seven new species, two new combinations, two new synonyms, and four new country records of Elaphidiini longhorned woodborers (Coleoptera: Cerambycidae) from the Dominican Republic are presented. Elaphidion compressipenne Fisher is transferred to Ceresium Newman as C. compressipenne (Fisher), new combination. Callidium lucidum Olivier is transferred to Metaphrenon Martins as M. lucidum (Olivier), new combination. A neotype (USNM) is designated for Elaphidion fullonium Newman, and Elaphidion confusum Fisher is a new synonym of that species. Elaphidion pilosum Fisher is a new synonym of Anelaphus mutatum (Gahan). Nesiosphaerion testaceum (Fisher), Anelaphus crispulum (Fisher), and Elaphidion androsensis Fisher are recorded for the first time from the Dominican Republic. Taxonomic confusion concerning Elaphidion bidens (Fabricius) is clarified. The following new species are described from the Dominican Republic: Anelaphus praeclarus Lingafelter (type locality: Guaraguao, La Altagracia Prov.), Nesiosphaerion charynae Lingafelter (type locality: Cabo Rojo, Pedernales Prov.), Psyrassa woodleyi Lingafelter (type locality: Road 47 between Los Pinos and Angel Félix, Independencia Prov.), Elaphidion auricoma Lingafelter (type locality: Guaraguao, La Altagracia Prov.), Elaphidion iviei Lingafelter (type locality: Filipinas, Barahona Prov.), Elaphidion nearnsi Lingafelter (type locality: Punta Cana, La Altagracia Prov.), and Elaphidion wappesi Lingafelter (type locality: Puerto Plata, Puerto Plata Prov.). A key to the twelve Elaphidion species from Hispaniola is provided.
Tyrtaeus rufus Champion and Tyrtaeus dobsoni Hinton (Coleoptera: Tenebrionidae: Anopidiina) are reported for the first time from Florida. Diagnoses of both species are presented, with illustrations, distributional and known biological data. Tyrtaeus guadeloupensis Dajoz is synonymized under Tyrtaeus rufus Champion NEW SYNONYMY. Tyrtaeus rufus is redescribed, and reported for the first time from Mexico, Costa Rica, Panama, Columbia, Venezuela, and the West Indian islands of Grand Cayman and Dominica. New records for Tyrtaeus dobsoni are reported for Luzon, Leyte and Samar of the Philippine Islands, and Majuro Atoll of the Marshall Islands. Tyrtaeus is incorporated into the North American tenebrionid key to genera in American Beetles.
An updated list of 79 species of Coccinellidae for South Dakota is presented. The list represents a net increase in the state coccinellid fauna from a previously published list of 66 species and subspecific taxa, and it also includes nomenclatural updates. Thirteen species have been added to the list as new state records: Didion punctatum (Melsheimer), Didion nanum (LeConte), Scymnus paracanus linearis Gordon, Scymnus fraternus LeConte, Hyperaspis inflexa Casey, Hyperaspis lugubris (Randall), Hyperaspis troglodytes Mulsant, Hyperaspis brunnescens Dobzhansky, Hyperaspis quadrivittata LeConte, Brachiacantha decempustulata (Melsheimer), Brumoides septentrionis septentrionis (Weise), Hippodamia expurgata Casey, and Hippodamia sinuata crotchi Casey. Two specimens of Coccinella septempunctata L., collected in 1978 represent a new state record of this species from South Dakota. Eight other species were added after reviewing previously published species records and faunal distribution maps. Several entries were deleted from the list based on synonymies. Four others were deleted because of dubious collection records, and one because of misidentification. Comments on recent collection records for adventive and declining native species of coccinellids are also presented. One C. transversoguttata richardsoni Brown from 2006 represents the only known specimen of this species curated since 1979, and one of a few individuals recorded in South Dakota since abundance declined after establishment of C. septempunctata.
