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.

This preliminary checklist of Aphodiini south of the United States is prepared to provide published data for a future web-based checklist of all New World Aphodiinae. All species names are used in combination with their currently accepted generic name, creating many new combinations. A few genus-species combinations are discussed. New synonymies based on recent studies of type specimens are made: Aphodius azteca Harold = Aphodius multimaculosus Hinton; Aphodius ornatus Schmidt = Aphodius magnopunctatus Hinton; Aphodius caracaensis Petrovitz = Aphodius brasilicola Balthasar; Aphodius guatemalensis Bates = Aphodius striatipennis Petrovitz; Aphodius kuntzeni Schmidt = Aphodius amplinotum Gordon and Howden = Aphodius michiliensis Deloya; Aphodius bimaculosus Schmidt = Aphodius xalapensis Galante et al.; Aphodius caracanus Balthasar = Aphodius martinsi Petrovitz; Aphodius volxemi Harold = Aphodius squamifer Petrovitz.

The naturalist Edward Newman did not provide an etymology for the mecopteran Merope tuber when he described it in 1838. In 1872 Asa Fitch asserted that the genus was named after Merope one of the Pleiades sisters of Greek mythology; however, he provided no reason for his assumption. We researched several etymological alternatives. We concur with Fitch and conclude that Newman did indeed name the genus Merope after the dullest of the Pleiades sisters.

Three distinct tibial types are recognized within the Rhyparini (Scarabaeidae, Aphodiinae). Based on this, generic limits for the species of Termitodius Wasmann are reevaluated, with the Old World members being transferred to Termitodiellus Nakane. The resulting new combinations are: Termitodiellus besucheti (Paulian), Termitodiellus hammondi (Krikken and Huijbregts), Termitodiellus interruptus (Krikken and Huijbregts), Termitodiellus luzonensis (Howden), Termitodiellus monticola (Krikken and Huijbregts). New World members of Termitodius are split into two genera: Termitodius Wasmann and Aschnarhyparus Makhan. Aschnarhyparus soesilae Makhan is here relegated to a junior synonym of Termitodius peregrinus Hinton, new synonymy, with the resulting new combination being Aschnarhyparus peregrinus (Hinton). A full description of Aschnarhyparus is presented, and Termitodiellus and Termitodius are diagnosed.

A new species of Physoconops Szilady, P. (Pachyconops) weemsi, is described from Florida and Georgia. It is similar to two other species in the southeastern United States, P. floridanus Camras and P. brachyrhynchus Macquart, the main differential character being the shape of the female theca. The female thecae for all three are illustrated and a key to the three related Pachyconops species occurring in the southeastern United States is presented.

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.
