Key to Korean species of the genus Libnotes Westwood, 1876

1. Vein Sc 1 reaching wing margin approximately at the level of Rs branching point, basal deflection of CuA 1 just slightly beyond branching point of M ( Fig. 7A ) ··· Libnotes (Afrolimonia) ladogensis ( Lackschewitz, 1940)

- Vein Sc 1 reaching wing margin far beyond branching point of Rs, basal deflection of CuA 1 at least its own length beyond branching point of M ( Fig. 7 B­G) ········ ···················································· Libnotes (Libnotes) 2

2. 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 ( Fig. 7B, C ) ·························································· ············ 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 ( Fig. 7 D­G) ······························ 3

3. Longitudinal veins, especially Cu and branches beyond cord patterned with lots of small spots ( Fig. 7E, G ) ··············································································· 4

- Longitudinal veins without small spots ( Fig. 7D, F ) ··· ···················································································· 5

4. Large species, wing length exceeds 15 mm. Small elongate spots distributed only along longitudinal veins ( Fig. 7E ) ······································································ ········ 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 ( Fig. 7G ) ····················································· ················· Libnotes (Libnotes) puella Alexander, 1925

5. Costal area of wing before humeral vein distinctly dark brown. Entire vein Cu surrounded by dark area, Rs has dark spot only at base ( Fig. 7D ) ······················· ····· Libnotes (Libnotes) basistrigata ( Alexander, 1934)

- Costal area at wing base not darkened. Vein Cu not surrounded by dark area, dark area extends along entire Rs ( Fig. 7F ) ·································································· ··············· Libnotes (Libnotes) nohirai Alexander, 1918
