Host. Unknown. There are three species of Megaxyela Ashmead , which are distributed in the South Korea : M. parki Shinohara, 1992 , M. gigantea Mocsáry, 1909 and undescribed species (Blank et al. in litt.), which may be the potential hosts of Proctorenyxa koreana sp. nov. Distribution. South Korea (Gyeongsangbuk-do, Gangwon-do). Etymology. The species is named after the type locality.
