Trox Hamatus Robinson (Troginae) Using A Canthon (Scarabaeinae) Brood Ball And New Records Of North American Trox (Coleoptera: Scarabaeidae), Brett C. Ratcliffe
University of Nebraska State Museum: Entomology Papers
Trox hamatus Robinson was observed feeding on an abandoned Canthon brood ball in southeastern Nebraska. Although some Aphodiinae and Scarabaeinae have been reported feeding on or stealing other scarabaeine dung balls, this represents the first reported observation of this behavior for a member of the Troginae. It is suggested that the brood ball was opportunistically used by the Trox, and the event is rare. In addition, new state records are provided for Trox aequalis Say, T. atrox LeConte, T. laticollis LeConte, and T. tesselatus (LeConte).

During the past several years a number of new taxa of Dynastinae have been described which we feel are synonymical with existing taxa. We have also accumulated a small number of new distributional records in the Pentodontini and Oryctini. In this paper we clarify some of these taxonomic "loose ends" by proposing several new synonyms and two new combinations. Dechambre examined the type of Heterogomphus niger Endrodi, and Ratcliffe examined the types of the three Endrodi species of Strategus and Endroedianibe bozzolai Chalumeau. We also list the new distributional records we have found.
