Species descriptions, keys to genera and species, and geographical distributions are presented for 43 species of the family Bruchidae (Coleoptera: Chrysomeloidea) for Chile. Of these species, seven are described as new:
Acanthoscelides aricae sp. nov., Lithraeus chillan sp. nov., L. comptus sp. nov., L. elguetai sp. nov., L. limari sp. nov., L. lonquimay sp. nov., and L. penai sp. nov. Eight species are endemic to Chile. A list of true host plants and floral records for those with known host associations is presented. Habitus photographs and drawings of pertinent body parts, including male genitalia, are provided. References pertaining to the previously described species are listed.
The Guadeloupe Archipelago, the French overseas Département de Guadeloupe, is a geographically associated group of islands and a natural biogeographic unit. The islands have been available for terrestrial colonization since the late Tertiary. From the viewpoint of beetle systematics and biodiversity, this is the most important set of islands of the Lesser Antilles because more species have been described or recorded from Guadeloupe than any other island or group in the Lesser Antilles. We present a summary of the 1338 beetle species recorded in the literature from the archipelago, in 60 families, and 719 genera. The families with the largest numbers of species are Curculionidae (420), Staphylinidae (153), Chrysomelidae (75), Cerambycidae (69), Scarabaeidae (64), and Tenebrionidae (59). Four hundred eighty two species are known only from one or more islands of the Guadeloupe group and likely speciated there. Guadeloupe is the type locality for an additional 59 species. At least 61 species have been accidentally introduced by human activities. A total of 261 species are known only from the Lesser Antilles including Guadeloupe. The remaining species are naturally more widespread in the Lesser Antilles, or the West Indies, and elsewhere in the New World. The actual number of species on the Guadeloupe Archipelago is estimated to be around 1850 or more species.
Neoma, a new genus of Cerambycidae (Coleoptera: Cerambycidae: Prioninae: Macrotomini) is described for Mallodonopsis corrosus Bates, 1879, compared to related genera (Aplagiognathus Thomson, 1861; Archodontes Lameere, 1903; and Mallodonopsis Thomson, 1861), and its tribal position discussed. A lectotype for Mallodonopsis corrosus is here designated with the species redescribed and figured.
This article outlines changes in procedures and production policies for the journal Insecta Mundi. Background data and discussions leading to these necessary changes are explained. Updated instructions for authors are presented. A full current version of author instructions will be posted on the latest Center for Systematic Entomology URL.
The New World genus Dysmerus Casey, currently with one valid species, is revised. Lectotypes are designated for two species, Dysmerus caseyi (Grouvelle), new status, and Dysmerus sulcicollis Grouvelle, new status. Both are revived from synonymy with D. basalis Casey. Twelve new species are described: Dysmerus boliviensis Thomas, new species, Dysmerus curvicornis Thomas, new species, Dysmerus genaspinosus Thomas, new species, Dysmerus hamaticornis Thomas, new species, Dysmerus impolitus Thomas, new species, Dysmerus skelleyi Thomas, new species, Dysmerus mexicanus Thomas, new species, Dysmerus monstrosus Thomas, new species, Dysmerus politus Thomas, new species, Dysmerus rondoniensis Thomas, new species, Dysmerus symphilus Thomas, new species, and Dysmerus trinidadensis Thomas, new species. A key to adults of the species and illustrations are provided.
The species of the genus Lathropus Erichson are reviewed for Florida and the West Indies, excluding the Lesser Antilles. Seven species are recorded from this region, three of which are described as new: Lathropus chickcharnie Thomas, new species, Lathropus jamaicensis Thomas, new species, and Lathropus rhabdophloeoides Thomas, new species. A lectotype is designated for Lathropus vernalis Casey, and Lathropus striatus Casey is synonymized under Lathropus vernalis Casey, new synonymy. Illustrations and a key to the species of this geographgic region are provided.
The Mesoamerican species of Telephanus distinguished by the presence eight lateral pronotal spines
and long temples are reviewed. The group includes T. serratus Nevermann and two previously undescribed species
that are described herein: T. bellus Thomas, new species, from Costa Rica, and the flightless T. monstrosus
Thomas, new species, from Mexico.
