Deltocephalinae (Hemiptera: Auchenorrhyncha: Cicadellidae) is the largest subfamily of Cicadellidae, and caused direct damage on their host plants by feeding and spawning, or as vectors of plant pathogens such as viruses, phytoplasmas, and bacteria. It contains majority of cicadellid vector species of economically important plant disease.
Despite of economical pests, Deltocephalinae is difficult to identify due to morphological similarities and variations, yet, their biological information like host plants and taxonomical characters has not been constructed for accurate diagnosis of species.
In this study, we build a database of integrated biological information such as host plants, distributional records and dorsal habitus of specimens, male genitalia, and DNA barcoding data with illustrations and photographs.
