The cyclocephaline scarabs (Scarabaeidae: Dynastinae: Cyclocephalini) are a speciose tribe of beetles that include species that are ecologically and economically important as pollinators and pests of agriculture and turf. We provide an overview and synopsis of the 14 genera of Cyclocephalini that includes information on: 1) the taxonomic and nomenclatural history of the group; 2) diagnosis and identification of immature life-stages; 3) economic importance in agroecosystems; 4) natural enemies of these beetles; 5) use as food by humans; 6) the importance of adults as pollination mutualists; 7) fossil cyclocephalines and the evolution of the group; 8) generic-level identification of adults. We provide an expanded identification key to genera of world Cyclocephalini and diagnoses for each genus. Character illustrations and generic-level distribution maps are provided along with discussions on the relationships of the tribe’s genera.

Cyclocephaline scarab beetles represent the second largest tribe of the subfamily Dynastinae, and the group includes the most speciose genus of dynastines, Cyclocephala. The period following publication of Sebő Endrődi’s The Dynastinae of the World has seen a huge increase in research interest on cyclocephalines, and much of this research has not been synthesized. The objective of this catalog and bibliography is to compile an exhaustive list of taxa in Cyclocephalini. This paper provides an updated foundation for understanding the taxonomy and classification of 14 genera and over 500 species in the tribe. It discusses the history of cataloging dynastine species, clarifies issues surrounding the neotype designations in Endrődi’s revision of Cyclocephalini, synthesizes all published distribution data for cyclocephaline species, and increases accessibility to the voluminous literature on the group by providing an easily searchable bibliography for each species. We propose the nomen novum Cyclocephala rogerpauli, new replacement name, for C. nigra Dechambre.

Diversity in the Weapons of Sexual Selection: Horn Evolution in the Beetle Genus Onthophagus (Coleoptera: Scarabaeidae)

et al. 2005

Abstract. Both ornaments and weapons of sexual selection frequently exhibit prolific interspecific diversity of form. Yet, most studies of this diversity have focused on ornaments involved with female mate choice, rather than on the weapons of male competition. With few exceptions, the mechanisms of divergence in weapon morphology remain largely unexplored. Here, we characterize the evolutionary radiation of one type of weapon: beetle horns. We use partial sequences from four nuclear and three mitochondrial genes to develop a phylogenetic hypothesis for a worldwide sample of 48 species from the dung beetle genus Onthophagus (Coleoptera: Scarabaeidae). We then use these data to test for multiple evolutionary origins of horns and to characterize the evolutionary radiation of horns. Although our limited sampling of one of the world's most species-rich genera almost certainly underestimates the number of evolutionary events, our phylogeny reveals prolific evolutionary lability of these exaggerated sexually selected weapons (more than 25 separate gains and losses of five different horn types). We discuss these results in the context of the natural history of these beetles and explore ways that sexual selection and ecology may have interacted to generate this extraordinary diversity of weapon morphology.Key words. Adaptive radiation, beetle horns, character divergence, male competition, Onthophagus, phylogeny, sexual selection, weapons.Received October 18, 2004. Accepted January 23, 2005 The history of life has been accentuated by several spectacular evolutionary radiations (Darwin 1871;Simpson 1949;Rensch 1959), and character divergence within these radiations frequently involves the exaggerated structures of sexual selection (Darwin 1871; West Eberhard 1983; Andersson 1994). The Hawaiian radiation of drosophilid flies, for example, has resulted in more than 900 extant species that differ most conspicuously in the wing patterns and courtship displays of males (Carson 1979;Templeton 1979;Kaneshiro and Boake 1987;Hoy et al. 1988;Kaneshiro 1988;Kambysellis et al. 1995). Similarly, radiations of birds-of-paradise, pheasants, and African Great Lake cichlids all involve the ornaments and displays of males (Beebe 1953;Gilliard 1969;Dominey 1984;Diamond 1986;Turner 1994;Deutsch 1997;Prum 1997;Frith and Beehler 1998; van Oppen et al. 1998). In fact, for a great many animals, the exaggerated structures of sexual selection display an evolutionary lability far surpassing that of other, not sexually selected structures (Darwin 1871;Geist 1966Geist , 1978Gilliard 1969; West-Eberhard 1983; Andersson 1994).Diversification of the ornaments and displays of mate choice is understandable-even expected. Numerous studies suggest that female choice can drive rapid divergence among populations (Lande 1981; West Eberhard 1983;Kaneshiro and Boake 1987;Endler and Houde 1995; van Oppen et al. 1998; Boake 2000;Uy and Borgia 2000;Boughman 2001;Masta and Maddison 2002;Mendelson 2003;Coleman et al. 2004).
