Abstract

The holotype of Delphacodes guianensis Muir, a delphacid planthopper (Hemiptera: Fulgoroidea: Delphacidae) currently nominally in the polyphyletic genus Delphacodes Fieber, was examined and found to bear lateral teeth on the hind basitarsus, a synapomorphy of the genus Nilaparvata Distant. We determined that Delphacodes guianensis is a senior synonym of Nilaparvata serrata Caldwell. Here we move this species into Nilaparvata to provide the new combination Nilaparvata guianensis (Muir) and give Nilaparvata serrata as a new junior synonym.
