 Abstract  Materials and Methods The mycophagous gall midges belonging to the family Cecidomyiidae contain 1,365 described • Adult specimens were collected by malaise traps, light traps, and sweeping in species in 114 genera six subfamilies worldwide. In Korea, 64 species were added, and one the Korean Peninsula (fig. 1). species was excluded from the Korean checklist of mycophagous gall midge by Bae, Ham, and • All samples were cleared in creosote reagent or potassium hydroxide(KOH), and Jaschhof from 2016. Now, 70 species in 32 genera from four subfamilies (Lestremiinae, Micro- made slide preparations under a stereomicroscope (Olympus AZ51, Tokyo, myinae, Winnertziinae, and Porricondylinae) are listed in the Korean checklist with three Japan) using canada balsam or hoyer. unrecorded species (Campylomyza abjecta Mamaev, 1998, Micromyia lucorum Rondami, 1840, • Microscopic images of the specimens were taken using an optical microscopy and Porricondyla gemina Jaschhof and Jaschhof, 2020). We provide the list, Korean names of all (Olympus BX50), with the aid of a microscope-attached camera (Nikon D750, the species, and diagnosis characters of newly recorded species. Tokyo, Japan). • The terminology used in the present study generally follows Jaschhof and  Introduction Jaschhof, 2013 • Cecidomyiidae is divided into three groups, phytophagous, predaceous, and sapro-myco- phagous gall midges, based on feeding habits of larvae (Yukawa 1971; Harris, 2004). Malaise trap • The mycophagous cecidomyiids contain 1,365 described species in 114 genera from six subfamilies worldwide (Gagné and Jaschhof, 2017). • In Korea, 64 species were added, and one species (Lestremia yasukunii; nomen dubium) was excluded from the Korean checklist of mycophagous gall midge by Bae, Ham, and from 2016 (Ham and Bae, 2016a; 2016b; 2017; Ham et al., 2018; Jaschhof, Ham, and Bae, 2018; Ham and Bae, 2018; Ham, Bae, and Jaschhof, 2019; 2020). • In Korea, 70 species in 32 genera from four subfamilies (Lestremiinae, Micromyinae, Winnertziinae, A B and Porricondylinae) are listed in the Korean checklist with three unrecorded species (Campylo- Figure 1.
