Box 141874 Gainesville, FL 32614-1874 USA http://centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non-marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi pub- lishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Ab- stracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Manuscript preparation guidelines are availablr at the CSE website.

Turnbow, Jr. 59 Brookview Ct. Enterprise, AL 36330, USA [email protected] Abstract. The Guadeloupe Archipelago, the French overseas Département de Guadeloupe, is a geographically associ- ated 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 intro- duced 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. Introduction The islands of the Caribbean are recognized as a “hotspot” for species biodiversity (Myers et al. 2000, Myers 2003, Mittermeier et al. 2004, Conservation International 2010a). This generalization is mostly based on data for only a few better-known groups such as vascular plants, terrestrial vertebrates and butterflies (Ricklefs and Lovette 1999). In reality, the terrestrial animal groups that are the most species diverse are the insect orders Diptera, Lepidoptera, Hymenoptera and especially Coleoptera (the beetles). These alone are estimated to account for some 20% or more of all the world’s animal species known to science (Wilson 1992). The goal and purpose of this report is to provide a summary and analysis of the species and distributions of all published records of the beetle fauna of the Guadeloupe Archipelago. This is a contribution to a longterm project to understand the diversity, evolution, and distribution of the beetles of the Lesser Antilles. The Islands Physical geography. The islands of the Guadeloupe Archipelago lie in the Leeward Islands group, in the upper half of the Lesser Antilles chain of islands of the West Indies (Fig. 1). Politically, the islands are 1 2 • INSECTA MUNDI 0352, February 2014 PECK ET AL. Figure 1.

They are a political unit of France equivalent to the status of Hawaii in the USA. All is French in language, customs, laws, etc., and there is also a creole language. The Archipelago is located between 15°50’ to 16°31’ N latitude and 61°00’ to 61°48’ W longitude. It lies be- tween the islands of Montserrat (53 km to the northwest) and Dominica (35 km to the south-southeast). It is composed of the
