Xyloryctes Hope, 1837 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) in the United States. Qui es et ubi fuisti et quo vadis?
(2009)
-
Brett C. Ratcliffe
- 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.

- With documentation of an unidentifiable adult female and juvenile Tingupidae (Chordeumatida), Kodiak Island, Alaska, becomes the westernmost indigenous diplopod locality in North America including continental islands. The northernmost and most proximate locality, Yakutat, lies ca. 935 mi (1,496 km) to the eastnortheast, while Haines, the type locality of Tingupa tlingitorum Shear and Shelley, some 1,196 mi (1,914 km) in this direction, is the most proximate familial site. Kodiak is also one of the most remote indigenous milliped localities in the Pacific, the most proximate ones to the west and south, Kamchatka, Russia, and the Hawaiian Islands, United States, being over 3,300 mi (5, 280 km) distant. Tingupidae is recorded for the first time from Canada excluding the Queen Charlotte Islands, and geographically remote, ostensibly indigenous records from the North Pacific Ocean and environs are tabulated.

The milliped families Spirostreptidae (Spirostreptida) and Paradoxosomatidae (Polydesmida) in the Middle East; first records of the Diplopoda from Saudi Arabia
(2009)
-
Rowland M. Shelley
- The class Diplopoda, represented by the families Spirostreptidae (Spirostreptida) and Paradoxosomatidae (Polydesmida), is recorded from Saudi Arabia for the first time. Archispirostreptus transmarinus Hoffman, 1965 (Spirostreptidae) inhabits the Jabal Al-Hijaz Mountains in the southwest, and the Paradoxosomatidae, represented by an unidentifiable, indigenous female, occurs in a “wadi” in the center of the country. Other Middle Eastern familial records are documented, and occurrences in the Arabian Peninsula are mapped. Males, necessary to identify the paradoxosomatid, may be encountered if samplings are timed to coincide with seasonal rains.

The Indo-Australian weevil genus Platytenes Pascoe, 1870 (Coleoptera: Curculionidae: Cryptorhynchinae)
(2009)
-
Gregory P. Setliff
Peter A. Larson
- 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.

The beetles of St. Lucia, Lesser Antilles (Insecta: Coleoptera): diversity and distributions
(2009)
-
Stewart B. Peck
- 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).

The beetles of Barbados, West Indies (Insecta: Coleoptera): diversity, distribution and faunal structure
(2009)
-
Stewart B. Peck
- 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.

Taxonomic redefinition of the genera Parataenius Balthasar and Pseudataenius Brown, with descriptions of three new species (Scarabaeidae: Aphodiinae: Eupariini)
(2009)

- 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.

Taxonomic overview of the greater fritillary genus Speyeria Scudder and the atlantis - hesperis species complexes, with species accounts, type images, and relevant literature (Lepidoptera: Nymphalidae)
(2009)

James C. Dunford
- 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.
