Abstract
Light trap surveys of adult Culicoides Latreille in the Republic of Korea (ROK) resulted in the capture of three previously unreported species, C. nasuensis Kitaoka, C. pallidulus Yu and C. jacobsoni Macfie. These new records are supported by supplementary morphological descriptions and DNA barcodes (mitochondrial cytochrome oxidase I or COI). An updated checklist of species reported from the ROK is provided.
