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 .)

1. Mid tibia with a row of distinctly strong p .................................................................. 2

- 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

3. Mesonotum with 1 distinct ia .................................................... subgenus Minettioides Malloch

- 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

- Mesonotum with anteriormost dc distinctly situated behind transverse suture, 0+3 dc ...........subgenus Homoneura Wulp

6. Face with lower margin at least three times as wide as height of gena in anterior view..... subgenus Euhomoneura Malloch

- Face with lower margin distinctly less than three times as wide as height of gena in anterior view..................................................................................................... subgenus Homoneura Wulp
