First record of the genus Alluaudomyia (Diptera: Ceratopogonidae) with five species in the Republic of Korea

The genus Alluaudomyia Kieffer, 1913 (Diptera: Ceratopogonidae) represents a diverse group of predaceous midges for their small size, pale coloration, and characteristic dark spot patterns on their wings, with a global distribution and 206 species documented to date. This study presents the first record of five Alluaudomyia species in the Korean Peninsula with a taxonomic key for these species and provides DNA barcoding data with COI region. Specimens were collected over a two-year period from the Republic of Korea using black light traps. The newly identified species were A. lucania Lee and Yu, 1997, A. quinquepicina Yu and Zhang, 2005, A. signosoma Yu and Zhang, 2005, A. tiberghieni Neveu, 1978, and A. tripartita Okada, 1942. These findings provide a foundation for further taxonomic studies and biodiversity assessments of Ceratopogonidae in Korea.
