Epimelitta postimelina Giesbert, 1996 and Odontocera apicula Bates, 1885 are transferred to the new genus Odontomelitta. Epimelitta postimelina, with closed procoxal cavities, cannot remain in Epimelittta Bates, 1870, a genus characterized by open procoxal cavities. The short elytra and tegmen (with caliper-shaped lateral lobes) of the aedeagus of both species excludes them from the genus Odontocera Audinet-Serville, 1833, with long elytra and tegmen (with strap-shaped lateral lobes). Both species are illustrated, and host plant and host flower records provided for O. apicula.

The island arc of the Lesser Antilles lies at the eastern margin of the Caribbean Sea in the Western Hemisphere, and stretches from the eastern end of the islands of the Greater Antilles (at the Virgin Islands), south to a position near the continental islands of Trinidad and Tobago at the north eastern corner of South America. The islands are a part of the West Indian Islands biodiversity “hotspot” and have been available for terrestrial colonization for about the past 15 million years. This is a status report on present knowledge of the beetle faunas of these islands, which is composed of 90 families, 1210 genera, and 2612 recognized species. Many additional species are not yet identified, or are unnamed, or remain to be discovered. Reported for the first time from the Lesser Antilles are four families, 49 genera, 105 species, and 1253 new island records. The largest families are Curculionidae (588 species), Staphylinidae (389 species), Chrysomelidae (181 species), Tenebrionidae (142 species), Cerambycidae (138 species), Scarabaeidae (127 species), and Carabidae (126 species). There are differing patterns of species distributions: 154 species are probably introduced by human activities; 985 are endemic species (limited to a single island); 465 are species endemic to more than one island of the Lesser Antilles; 212 are species limited to just islands of the West Indies; and 800 are native (naturally occurring) species which also have part of their distributional range in North, Central, or South America. Most of the widely distributed beetle fauna has probably come from South America by over-water dispersal. There is no compelling evidence for a vicariance origin of any part of the beetle fauna. Earlier colonists have had more time to form endemic genera (18) and endemic species. The more widely distributed species probably represent distributions achieved in and since the Pleistocene.

The primary types of Onciderini Thomson, 1860 of the Muséum national d’Histoire naturelle (MNHN), Paris, are catalogued and illustrated. Data on the original combination, current name, gender, and type locality are verifi ed and presented. There are 139 primary types of Onciderini including 38 in Oncideres Lacordaire, 1830; 17 in Hypsioma Audinet-Serville, 1835; 10 in Hesycha Fairmaire and Germain, 1859; nine in Hypselomus Perty, 1832; and eight each in Eudesmus Audinet-Serville, 1835 and Trestonia Buquet, 1859. Of the 139 primary types, 71 were described by J. Thomson, 34 by H. W. Bates, 13 by the authors of this work, and 11 by J. B. L. Buquet. One neotype and 57 lectotypes are designated. Notes on additional Onciderini types once believed to be deposited at the MNHN are presented. A brief history of the Coleoptera collection at the MNHN is also presented.

In recent years, populations of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), have increased in rural citrus orchards and urban backyard gardens. In order to fi nd biological control options for D. citri, a search for natural enemies was conducted in the department of Valle del Cauca, Colombia. The collections were carried out in citrus orchards in rural areas and house gardens and street trees in urban areas.
Natural enemies were collected from D. citri found on Citrus spp. and Murraya paniculata (L.) Jack (Rutaceae). A total of 16 species of natural enemies of D. citri distributed in six families in fi ve orders are reported from Colombia.
Herein we provide an updated list of 95 species of arthropod (arachnids and insects) natural enemies of D. citri distributed in nine orders and 23 families recorded worldwide.

A new scarab species of the genus Lycomedes Brème, 1844 is described, totaling fi ve species of the genus reported for Colombia. Lycomedes salazari was collected in an oak forest at the high Andean region of Santurbán in the municipality of California, Santander Department, Colombia. Besides inhabiting the highest altitude known for the genus, L. salazari has affi nities with L. buckleyi Waterhouse, 1880, but differs on the cephalic, thoracic and leg morphologies. Biological notes and an updated key for the adults of the genus are included.

Two new species of Corimbion Martins, 1970 are described from Bolivia: Corimbion kuckartzi and Corimbion ledezmae. A previous key to the South American species of Corimbion (Martins 2009) is herein modified to include the new species. Dorsal, ventral and lateral habitus illustrations, as well as variation in color and dorsal pattern for C. kuckartzi, are also presented.

New species of anthophilous Cerambycinae (Coleoptera, Cerambycidae) are described from Bolivia:
Molorchini, Merionoedopsis zamalloae sp. nov.; Heteropsini, Chrysoprasis azurearegina sp. nov., and C. maryhowardae sp. nov.; Rhopalophorini, Dihammaphora densiserrata sp. nov., D. dilmanappae sp. nov., D. espinotibia sp. nov., D. fosterorum sp. nov., D. paraperforata sp. nov., D. pilcomayoensis sp. nov., and Rhopalophora santacruzensis sp. nov. All species are illustrated and host flower records are provided.

Klugiatragus gen. nov. is described for Epimelitta laticornis (Klug, 1825) because this species has closed procoxal cavities, a crucial diagnostic incompatible with Epimelitta Bates, 1870, which has open procoxal cavities. Both sexes of this species are illustrated.
