Identification of caddisfly specimens from Vietnam collected by scientific field staff of the Royal Ontario Museum and the American Museum of Natural History revealed 19 new country records. All but one species were reported from other Oriental region countries, particularly Thailand and Indonesia. However, Goera kawamotonis Kobayashi 1987 was only known from the East Palaearctic region (Japan and Russian Far East). The total number of species now recorded from Vietnam is 400.

The genus Haroldiataenius Chalumeau, 1981 (Aphodiinae: Eupariini) from southern United States, Mexico, and Central America is revised and nine species are recognized. The subgeneric name Sayloria Chalumeau, 1981 is synonymized with Haroldiataenius (sensu stricto) and Ataenius sabinoi Cartwright, 1974 is synonymized with A. lucanus Horn, 1871. Five species are transferred to Haroldiataenius from the genus Ataenius Harold creating the following new combinations: H. convexus (Robinson), H. griffini (Cartwright), H. lucanus (Horn), H. saramari (Cartwright), and H. semipilosus (Van Dyke). One new species,Haroldiataenius buvexus is described from Texas, USA. A key to species of Haroldiataenius is included and pertinent morphological details are illustrated.

The New World euparine scarab genera Parataenius Balthasar, 1961 and Pseudataenius Brown, 1927 are revised. Ataenius brunneus Schmidt is transferred to the genus Parataenius becoming Parataenius brunneus (Schmidt), new combination. The monospecific genus Ataenioides Petrovitz, 1973, is synonymized with Pseudataenius Brown, 1927, (new synonymy) and the type species, Ataenioides gracilitarsis Petrovitz, is given the new combination Pseudataenius gracilitarsis (Petrovitz). New species of Parataenius are described from southern South America: Parataenius selvae, P. estero, and P. martinezi. Keys for species of both genera are presented and pertinent morphological details are illustrated.

A taxonomic overview for the fritillary genus Speyeria Scudder (= Argynnis Fabricius) and its placement within the Heliconiinae (Nymphalidae) is presented. Taxonomic accounts, type images, and relevant literature for the 25 subspecies within the Speyeria atlantis (Edwards) and Speyeria hesperis (Edwards) complexes and the 16 nominate Speyeria species are included. Errors in nomenclature are identified, taxonomic, life history, and distributional information are updated, and type locality information is discussed. Images of primary type specimens for all 16 Speyeria species and the 25 subspecies in the atlantis - hesperis complexes appear together in color here for the first time. One new combination of a species-subspecies is created: Speyeria hesperis hanseni Emmel, Emmel, and Matoon, 1998, new combination, which was previously Speyeria atlantis hanseni Emmel, Emmel, and Matoon.

The beetle fauna of the island of Barbados is summarized. It is now known to contain 202 genera, and 254 species (in 40 families), of which 232 are named at the species level. Undoubtedly, the actual numbers of species on Barbados are much higher than now known. Nine species are possibly endemic to the island, 15 have been intentionally introduced, and 51 have probably been accidentally introduced through human activity. The remaining 157 named species may occur naturally as a result of natural over-water dispersal processes. These species mostly have a wide distribution in the Antilles and Latin America. The total named fauna is thus about 72% naturally occurring, and 28% the result of human-aided dispersal.

Review of the Natural History of the Handsome Fungus Beetles (Coleoptera: Cucujoidea: Endomychidae)
(2009)
The literature pertaining to natural history of Endomychidae (Coleoptera: Cucujoidea) is reviewed. One hundred fungal host records are provided for 32 endomychid species. Twenty-three records of endomychid yeast endosymbionts are compiled. Summaries are also presented for feeding preferences, interactions with natural enemies, non-lethal symbiotic relationships, and pest activity within the family. Unusual endomychid behaviors and habitats are reviewed, with particular attention to gregariousness and defensive strategies within Endomychidae.

This study provides a species-level phylogeny and morphological characterization for the Neotropical brassoline genus Dasyophthalma Westwood, 1851. A revised generic definition is given, and two species groups are proposed. Diagnoses and illustrations of habitus and genitalia are provided for all species. Wing color, male scent organs, and male and female genitalic morphology are characterized and discussed.

Two samples of the chordeumatidan family Rhiscosomididae (Rhiscosomides mineri Silvestri, 1909) and 35 of the Conotylidae establish these taxa in the Alexander Archipelago and continental parts of the Alaskan Panhandle, USA, and northern coastal British Columbia (BC), Canada. Rhiscosomides mineri is also recorded from southwestern BC and, for the first time, from Washington State, USA. Two conotylids were recovered, a juvenile male of ?Bollmanella Chamberlin, 1941, and 3 males and 33 females of a possibly parthenogenetic form of Taiyutyla Chamberlin, 1952, conforming generally to T. shawi and T. lupus, both by Shear, 2004, on Vancouver Island. Diplopoda are predicted to inhabit the southern Yukon Territory.

The formerly monotypic weevil genus Platytenes Pascoe (Coleoptera: Curculionidae: Cryptorhynchinae: Cryptorhynchini: Cryptorhynchina) as treated here, includes two commonly encountered and broadly distributed species in the eastern Indo-Australian region. Label data indicate that both species are associated with semicultivated betel palm (Areca catechu L., Arecaceae) and human mediated dispersal is suggested to have influenced their present-day distribution. Herein, we provide a diagnosis for Platytenes and redescribe its type species, P. varius Pascoe. We also describe P. occultus Setliff and Larson, a new species from the Solomon Islands. New host and locality records are provided, including the first records of the genus occurring on Ambon Island, the Bismarck Archipelago, D’Entrecasteaux Islands, and many previously unreported localities on New Guinea. A full bibliography, key to species, and distribution map for the genus are also provided.

Megatharsis buckleyi Waterhouse, 1891 is newly recorded from Brazil, extending its distributional range beyond Ecuador and Peru. A further new provincial record from Ecuador is presented in detail, and the species’ distribution and habitat is discussed. Color variation within the species, with a possible geographic correlation, is reported here for the first time.

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 of importance to land management and conservation interests on these rapidly changing and ecologically fragile islands.

New distribution records for the State of Florida are given for several genera and species of water beetles. These include Dytiscidae: Acilius confusus Bergsten; Dytiscus carolinus Aubé; Matus bicarinatus (Say); Elmidae: Oulimnius nitidulus LeConte; Stenelmis mera Sanderson; S. morsei White; Hydrophilidae: Laccobius minutoides d’Orchymont; Scirtidae: Sarabandus robustus (LeConte); Scirtes oblongus Guérin-Méneville. Additional information is provided on the distribution, morphology and three color forms of S. oblongus which is considered to be a senior synonym of Scirtes sexlineatus Chevrolat and S. interruptus Chevrolat.

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.

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 decline of Fraxinus spp., the food plant of Xyloryctes species, as a result of damage caused by the introduced emerald ash borer (Agrilus planipennis Fairmaire; Buprestidae) in the United States might portend a similar decline for Xyloryctes species in North America.

Six species of the tribe Oryctini, one species of Agaocephalini, and two species of Dynastini are presently recorded from the Cayo district of western Belize. The following five species are newly recorded from Belize: Heterogomphus mniszechi (Thomson), Strategus longichomperus Ratcliffe, S. jugurtha Burmeister, Spodistes mniszechi (Thomson), and Dynastes hercules (Linnaeus). The following two species are newly recorded from Cayo: Enema endymion Chevrolat and Strategus aloeus (Linnaeus). Biological and distributional comments relating to these records are presented and briefly discussed.

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 of species on St. Lucia are many times higher than now reported and may originally have been as high as around 1400 species. Of the St. Lucia species known to occur on other islands, the largest numbers are shared with Guadeloupe (102), St. Vincent (79), and Martinique (55).
