Additionally, researchers in the United States and South America have greatly expanded the agronomic literature on the tribe since publication of The Dynastinae of the World.
Many faunistic studies in Mesoamerica (especially Mexico) and South America have reported a great deal of cyclocephaline locality data that has yet to be synthesized. Starting in the mid-1970s, a growing body of research covering the floral ecology of cyclocephalines began to develop. The synonymy curve also includes names that were homonyms and later replaced. Species description accumulation was based on the compiled catalog. (Fig.1), 1), many new South American taxa are likely to be discovered, especially in the genera Cyclocephala and Stenocrates Burmeister ( Ratcliffe 2015).Ĭumulative number of described cyclocephaline species-group taxa by decade. While the most intense period of new species descriptions has probably passed (Fig. Over 170 new cyclocephaline species-group taxa have been described since 1985, and this has created challenges for species identification in several genera. unamas Ratcliffe (Spanish “una mas”) was named after the overwhelming feeling one gets after the discovery of yet another new Cyclocephala species, epitomized by the species name C. Papers on cyclocephalines now span all modern entomological disciplines from taxonomy, evolutionary biology, ecology, ethology, agronomics, and physiology.Įver-growing numbers of cyclocephaline species have, at times, engendered lighthearted dismay among researchers of the group. The post-Endrődi era of cyclocephaline research has been marked by ever diversifying interests and approaches to the group. This influence is most apparent in the scientific literature covering cyclocephaline scarab beetles. Endrődi’s foundational book revolutionized the study of the subfamily and paved the way for a veritable explosion of new research into dynastines. The last comprehensive, synoptic treatment of the tribe was The Dynastinae of the World ( Endrődi 1985a). Cyclocephala Dejean, the type genus of Cyclocephalini, is the most speciose dynastine genus and comprises over 350 species-group taxa as of 2017. The Cyclocephalini, a group first defined by French naturalist Francis de Laporte de Castelnau in 1840, represents the second largest tribe of the subfamily Dynastinae. We propose the nomen novum Cyclocephala rogerpauli, new replacement name, for C.
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. This paper provides an updated foundation for understanding the taxonomy and classification of 14 genera and over 500 species in the tribe. The objective of this catalog and bibliography is to compile an exhaustive list of taxa in Cyclocephalini. 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. Cyclocephaline scarab beetles represent the second largest tribe of the subfamily Dynastinae, and the group includes the most speciose genus of dynastines, Cyclocephala.
