The Beetles Of St. Lucia, Lesser Antilles (Insecta: Coleoptera): Diversity And Distributions, Stewart B. Peck
The Beetles Of St. Lucia, Lesser Antilles (Insecta: Coleoptera): Diversity And Distributions, Stewart B. Peck
Insecta Mundi
The published beetle fauna of the island of St. Lucia is summarized. It contains 135 genera, and 175 species in 25 families. Four species are accidentally introduced by human activities. Twenty three species are endemic (restricted) to the island. Twenty seven species on St. Lucia are shared only with other islands of the Lesser Antilles, and 22 species are widespread Antilles endemics. The remaining 56.6% of the fauna is otherwise mostly one which is widely distributed in the Antilles and the Neotropics. This suggests that it is mostly an immigrant fauna originating in the continental Neotropics. Undoubtedly, the actual numbers …

Generic Reassignment Of Species In The Tribe Cephaloleiini Chapuis, 1875 (Coleoptera: Cassidinae), C. L. Staines
Generic Reassignment Of Species In The Tribe Cephaloleiini Chapuis, 1875 (Coleoptera: Cassidinae), C. L. Staines
Insecta Mundi
Thirty-one species of Cephaloleiini are assigned to new genera, creating new combinations: 19 to Parimatidium Spaeth, 10 to Stilpnaspis Weise, and two to Demotispa Baly. Demotispa peruana membrata Uhmann, 1957 is raised to full species status. As the transfer of Cephaloleia limbatum Pic to Demotispa creates a homonymy, the species is renamed Demotispa pici nomen novum.

Xyloryctes Hope, 1837 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) In The United States. Qui Es Et Ubi Fuisti Et Quo Vadis?, Brett C. Ratcliffe
Insecta Mundi
Two species of Xyloryctes occur in the United States: X. jamaicensis (Drury) and X. thestalus Bates. Identification and distribution of these species has long been confused but is reviewed and clarified here. Xyloryctes jamaicensis occurs only in the eastern half of the U.S. and not in the southwestern U.S. as previously thought, while X. thestalus occurs in Guatemala and southern Mexico northwards to the southwestern United States. This hypothesis is corroborated by biogeographical and host plant data. Three new synonyms are listed for X. thestalus: X. faunus Casey 1915, X. hebes Casey 1915, and X. thestalus borealis Endrödi. The …

A New Fossil Species Of Stag Beetle From Dominican Republic Amber, With Australasian Connections (Coleoptera: Lucanidae), Robert E. Woodruff
Insecta Mundi
The first New World amber member of the family Lucanidae is described from the Dominican Republic. Its age is presumed to be Miocene (20-30 million YBP). It is also the fourth known amber species, the second Miocene fossil species, the second fossil species in the subfamily Syndesinae, and the first species (fossil or extant) of Lucanidae from the entire Caribbean. It is especially interesting because it is a member of the Australasian genus Syndesus MacLeay. Other such disjunct Dominican amber insect fossils are also discussed.

Beetle Species Diversity In The Lesser Antilles Islands: How Many Species Are Really There?, Stewart B. Peck
Beetle Species Diversity In The Lesser Antilles Islands: How Many Species Are Really There?, Stewart B. Peck
Insecta Mundi
Recent extensive and intensive field work by the team of M. A. Ivie on the Lesser Antillean island of Montserrat suggests that a mean of 827 beetle species may be expected on that island. This datum makes possible the generation of hypotheses of the probable beetle species diversity on other islands of the Lesser Antilles as a function of the areas of the islands. Figures are given for the presently known, estimated total, and estimated number of unknown species for each principal island. This predicts that many hundreds (if not thousands) of beetle species remain to be discovered. This is …
