A New Tribe, a New Genus, and a New Species of the Subfamily Dictyopharinae (Homoptera, Dictyopharidae) from Chile

摘要

Rancoda rakitovi gen. et sp. n. is described from Chile (the La Campana National Park, Valparaiso Region), for which a new monotypical tribe Rancodini trib. n. is established in the subfamily Dictyopharinae. The characteristic features of the new tribe are sharp brachyptery (the orgerioid habitus), the presence of sensory pits in the adults, two spines in the inner group on the apex of the hind tibia, a simple median carina on the abdominal ter-gites, and the straight margin between the metope and the clypeus. Similarity between the advanced representatives of the subfamily Orgernnae (sensory pits in the adults) is convergent and is combined with the primitive characters which are absent in all the Orgeriinae but present in the Dictyopharinae.
