The seven genera and 13 species of dynastine scarabs recorded from the Bahamas are reviewed. Two of those species are endemic, including Cyclocephala dolichotarsa Ratcliffe and Cave, new species, described from Great Inagua Island. Eleven species are also known to occur in the USA and/or Cuba. Six species are probably not established based on infrequency of collection.

Trypoxylon (Trypargilum) mexicanum (Hymenoptera: Crabronidae) belongs to the albitarse group, which includes the larger species of the genus. Its native distribution extends throughout Central America from Mexico to Panama. Here it is reported for the first time from Hispaniola, West Indies. Because it is difficult to envisage such a conspicuous species having eluded capture any naturalist or aculeate specialist previously, I consider that it has recently arrived on the island. It may have arrived due to the trade with Central America, since the nests, made of mud, can easily transport the immatures that subsequently emerge and disperse after their arrival on the island. T. mexicanum is established at least in the Dominican Republic, with a wide distribution and large populations. This demonstrates the ecological success of a recently established population on the island, perhaps due to escape from natural enemies and an absence of other limiting factors. The females were observed at puddles of water on the roads where they pick up mud with which they construct their tubular nests. Brood cells were provisioned exclusively with several species of spiders of Araneidae. An endemic spider, Eustala bisetosa Bryant was also used as prey. Other data about natural history is also provided.

The genus name Drepanocanthoides Schmidt has recently been applied to Australian and North American taxa, based on generic concepts following separate designations of different type species. Drepanocanthoides, type species Aphodius walshii Horn, is a Nearctic genus that is not congeneric with the Australian members. The new name Ozodius, n. gen., is here proposed for the Australian taxa, with Aphodius neglectus Schmidt designated as the type species. All Australian members of Drepanocanthoides are transferred to Ozodius.

Nomenclatural errors associated with the nymphalid butterfly, Speyeria atlantis greyi Moeck, have persisted in the literature and electronic databases. We present here a synonymy of the various combinations and misspellings associated with it and clearly indicate the correct name and spelling based on Moecks (1950) original description. Additionally, color images of the holotype and allotype specimens are published herein for the first time.

Generic placement of Nearctic species of Ochodaeinae has lagged behind changes in generic concepts in the group. In order to place Nearctic species into the appropriate genus-level taxa, several nomenclatural changes are made. The new generic name Xenochodaeus is proposed for species with an elongate, subparallel sulcus on the propygidium and a longitudinally impressed mentum. The genus contains 6 species. Xenochodaeus americanus (Westwood), new combination, is valid and is removed from synonymy with X. musculus (Say), new combination. A neotype is designated for Odontaeus musculus. Ochodaeus opacus LeConte is synonymized under X. americanus. Other new combinations include Xenochodaeus luscinus (Howden), X. planifrons (Schaeffer), X. simplex (LeConte), and X. ulkei (Horn). The new generic name Cucochodaeus is proposed for species having the propygidial sulcus absent, stridulatory peg absent, and possessing 9 antennomeres. The genus contains 1 species, C. sparsus (LeConte), new combination. Ochodaeus mandibularis Linell is placed into synonymy with C. sparsus. Ochodaeus gnatho Fall is transferred to the genus Codocera Eschscholtz, resulting in C. gnatho (Fall), new combination. Two new combinations result from Nearctic species transferred to Neochodaeus Nikolajev: N. repandus (Fall) and N. striatus (LeConte). Three Nearctic species are transferred to Parochodaeus Nikolajev, resulting in new combinations: Parochodaeus californicus (Horn), P. duplex (LeConte), and P. peninsularis (Horn). A lectotype is designated for Ochodaeus kansanus Fall, and that same specimen is designated as the neotype of Ochodaeus duplex (LeConte), objectively synonymizing O. kansanus with O. duplex. A checklist of Nearctic species and key to Nearctic genera are provided.

New South American taxa of Odontolochini Stebnicka and Howden (Coleoptera: Scarabaeidae: Aphodiinae)
(2007)
Recently discovered Neotropical taxa belonging in the tribe Odontolochini Stebnicka and Howden (Coleoptera: Scarabaeidae: Aphodiinae) are described. New genera are: Amerilochus, type species Amerilochus cinereus, new species; and Stebnickiella, type species Stebnickiella zosterixys, new species. Three additional new species are: Saprolochus lobatus, Saprolochus tridentatus, and Saprositellus kenodontus. Updated keys are presented to the New World genera of Odontolochini as well as keys to species in the genera Saprolochus Stebnicka and Galante and Saprositellus Balthasar. New country records are presented for Saprositellus ariquemes Stebnicka.

New locality records for Culiseta inornata (Williston) are reported from Big Pine Key, Grassy Key, and No Name Key in Monroe County, Florida. Five specimens were collected in dry ice-baited light traps. An old, previously unrecognized record for Anopheles grabhamii Theobald from Miami, Dade County, Florida, is reported based on specimens found in the Florida State Collection of Arthropods.

Mutual grooming in two genera of silvanid beetles is described, and appears to be the first report of this behavior in the order Coleoptera. In Uleiota debilis (LeConte), allogrooming recipients were either stationary or moved away during the acts, without solicitation or facilitation. In Nausibius major Zimmermann, allogrooming was much more extensive and the individual being groomed appeared to facilitate the process by immobility or by changes in posture, there were no recognizable sexual overtones, no solicitations, and no avoidance movements. Gregarious behaviors of some other silvanid beetles are reviewed.
