Abstract:

We describe a new genus of anomaline scarab, Anomalorhina (Coleoptera: Scarabaeidae: Rutelinae: Anomalini) from Costa Rica and Nicaragua. Anomala turrialbana Ohaus is transferred into this genus, and a new species, Anomalorhina osaensis, is described. Anomalorhina is characterized by the clypeal apex that is abruptly reflexed, the base of the frons that has prominent tubercles in males, the pronotum with a depressed fovea in males, and the pronotum with the apical bead posteriorly produced and V-shaped at the middle in females. We summarize the biological importance of the 16 genera of New World anomaline scarabs, including comments on agricultural pests, larvae, and natural history. We provide an overview and synopsis of each of the New World anomaline genera with comments on biology and characteristics for identification.RESUMEN Se describe un género nuevo de escarabajos anomalinos, Anomalorhina (Coleoptera: Scarabaeidae: Rutelinae) de Costa Rica y Nicaragua. Se transfiere Anomala turrialbana Ohaus a este género nuevo, y se describe una especie nueva, Anomalorhina osaensis. Anomalorhina se caracteriza por tener el ápice del clípeo abruptamente elevado, los machos presentan dos tubérculos prominentes en la base frontal de la cabeza y una fovea en el pronoto, y las hembras tienen el pronoto con el área media del margen anterior proyectado posteriormente en forma de V. Se presenta un sumario sobre la importancia biológica de los 16 géneros de Anomalini del nuevo mundo que incluye comentarios sobre las plagas agrícolas, larvas e historia natural. Se provee una sinopsis de cada género de Anomalini del nuevo mundo con comentarios sobre su biología y características para su identificación.
