Key to Korean species of the genus Libnotes Westwood, 1876

1. Vein Sc1 reaching wing margin at or close to the level of branching point of Rs, basal deflection of CuA1 just slightly beyond branching point of M ( Fig. 1 )........................................................ Libnotes (Afrolimonia) ... 2

-. Vein Sc1 reaching wing margin far beyond branching point of Rs, basal deflection of CuA1 at least its own length beyond branching point of M ( Fig. 5 ).......................................................... Libnotes (Libnotes) ...3

2. Thorax generally dark brown, paramere of male genitalia with triangle-shaped distal part, hypogynial valve of ovipositor ends distinctly before tip of cercus................................ Libnotes (Afrolimonia) ladogensis ( Lackschewitz, 1940)

-. Thorax black, paramere of male genitalia with finger-shaped distal part ( Fig. 2 ), hypogynial valve of ovipositor nearly reaches tip of cercus ( Fig. 3 )........................................... Libnotes (Afrolimonia) plutonis ( Alexander, 1924)

3. General body coloration yellow ( Figs. 6, 7 )................................................................. 4

-. General body coloration brown ( Fig. 11 )................................................................... 5

4. Costal area of wing before humeral vein distinctly dark brown. Entire vein Cu surrounded by dark area.............................................................................. Libnotes (Libnotes) basistrigata ( Alexander, 1934)

-. Costal area at wing base not darkened. Vein Cu not surrounded by dark area ( Fig. 5 )..................................................................................................... Libnotes (Libnotes) charlesyoungi n. sp.

5. Wing patterned with large dark brown spots, which usually make cross bands at least at cord and at the level of stigma—distal margin of discal cell. Radial sector (Rs) entirely surrounded by distinct dark brown area.............................................................................................. Libnotes (Libnotes) amatrix ( Alexander, 1922)

-. Wing patterned with small brownish or grayish spots and narrowly darkened areas at cord and distal margin of discal cell at most................................................................................................ 6

6. Longitudinal veins, especially Cu and branches beyond cord patterned with many small spots........................ 7

7. Large species, wing length exceeds 15 mm. Small elongate spots distributed only along longitudinal veins.............................................................................. Libnotes (Libnotes) longistigma Alexander, 1921

-. Small species, wing length not exceeds 10 mm. Small rounded spots distributed not only along veins, but also in all cells...................................................................... Libnotes (Libnotes) puella Alexander, 1925

8. Middle of Rs not surrounded by dark area ( Fig. 11 )................................ Libnotes (Libnotes) jirisana n. sp.

-. Entire Rs surrounded by dark area..................................... Libnotes (Libnotes) nohirai Alexander, 1918
