Key to five subgenera of the genus Homoneura

(The following key is modified from the keys of Sasakawa (1992), Stuckenberg (1971) and Malloch (1929). The key of Stuckenberg (1971) is adequate to get to the genus Homoneura .)

- Mid tibia without a row of p ............................................................................. 3

2. Mesonotum with 2 sa (posterior sa at least 1/2 length of anterior sa); mid tibia with 4 apv (longer than the biggest diameter of mid tibia); mid femur with a row of strong pv, rarely absent...................................subgenus Chaetohomoneura Malloch, 1927a

- Mesonotum with 1 sa; mid tibia with 3 apv (longer than the biggest diameter of mid tibia); mid femur without strong pv..... ....................................................................subgenus Neohomoneura Malloch, 1927a

- Mesonotum without ia ................................................................................. 4

4. Mesonotum with anteriormost dc distinctly situated before or behind transverse suture............................... 5

- Mesonotum with anteriormost dc situated at transverse suture.................................................. 6

5. Mesonotum with anteriormost dc distinctly situated before transverse suture, 1+2 dc ...... subgenus Euhomoneura Malloch
