(updated from Podenas, 2016)

1. Wing cells r3 and r5 with additional cross-veins (Fig. 2)................................. Libnotes (Laosa) charmosyne

- Wing cells r3 and r5 without additional cross-veins (Figs. 7, 11)................................................. 2

2. Basal deflection of CuA1 short distance beyond branching point of M .......................... Libnotes (Afrolimonia) 3

- Basal deflection of CuA1 at least its own length beyond branching point of M (Figs. 7, 11)............ Libnotes (Libnotes) 4

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

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

4. Vein Sc1 reaching wing margin far beyond branching point of Rs; body length above 6 mm ........................... 5

- Vein Sc1 reaching wing margin at or close to the level of branching point of Rs (Figs. 7, 11); body up to 5 mm long....... 11

5. General body coloration yellow.......................................................................... 6

- General body coloration brown........................................................................... 7

6. Costal area of wing before humeral vein distinctly dark brown. Entire vein Cu surrounded by dark area............................................................................................. Libnotes (Libnotes) basistrigata

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

7. 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

- Wing patterned with small brownish or grayish spots and narrowly darkened areas at cord and distal margin of discal cell at most................................................................................................ 8

8. Longitudinal veins, especially Cu and branches beyond cord, patterned with abundant small spots...................... 9

- Longitudinal veins without small spots.................................................................... 10

9. Wing more than 15 mm long. Small elongate spots distributed only along longitudinal veins. Libnotes (Libnotes) longistigma

- Wing up to 10 mm long. Small rounded spots distributed not only along veins, but also in all cells. Libnotes (Libnotes) puella

10. Middle of Rs not surrounded by dark area............................................ Libnotes (Libnotes) jirisana

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

11. Vein A2 long and nearly straight; basal section of R4+5 nearly longitudinal, at right angle to r-m; r-m beyond base of discal cell (Fig. 7).................................................................. Libnotes (Libnotes) byersiana n. sp.

- Vein A2 short, distinctly arched; basal section of R4+5 transverse, in alignment with r-m; r-m at base of discal cell (Fig. 11)................................................................................. Libnotes (Libnotes) divaricata
