Delphacidae is the most diverse group in the Superfamily Fulgoroidea (Hemiptera: Auchenorrhyncha: Fulgoromorpha) with more than 2000 reported species worldwide. This group is commonly called planthoppers, because most members are grass-feeding species. Some members are known as vectors of economically important plant viruses, and damage to several crops in many countries. Stenocranus is one of the biggest groups in the Delphacidae. In Korea, there have been eight recorded species. In this presentation, we present taxonomic review of the Stenocranus with a new record in Korea. Morphological characters and key to Korean species are presented.
