As a result of an ongoing systematic study of the genus Phasia Latreille in Korea, we have discovered P. aurigera and P. takanoi for the first time in Korea. We here provide detailed redescriptions and illustrations with their diagnostic characters indicated. Phasia aurigera can be distinguished from other congeners by the combination of the following characteristics: 1) scutum with distinct yellow pruinose spot; 2) male abdominal tergite 5 posteromarginally with V-shaped yellow pruinosity; 3) distiphallus divided into anterior and posterior processes; 4) female sternite 7 short, as long as or slightly longer than sternite 6 (visible part); and 5) female sternite 8 (ovipositor) bent dorsally. Phasia takanoi can also be distinguished by the combination of the following characteristics: 1) abdominal tergites strongly shiny; 2) surstylus strongly bent upward; and 3) posterior margin of female sternite 7 straight in ventral view.
