Subfamily Phasmatinae Identification Key

The following table by Bradley & Galil is pretty much useless. Australian authors include many genera Acrophylla, Ctenomorpha, Ctenomorphodes, Eurycnema, Onchestus and Paronchestus) which it fails to mention at all.

1. Both sexes, or at least female, apterous 6

- Both sexes alate or with wing rudiments 2

2. Cerci of female short and slender; male without ocelli; elytra or wings of female often strongly reduced 3

- Cerci of female strongly flattened and widened or elongate and lanceolate; ocelli of male distinct Phasmatini (Acrophylla, Anchiale, Ctenomorpha, Ctenomorphodes, Eurycnema, Onchestus, Paronchestus, Vetilia)

3. Operculum of female not exceptionally long 5

- Operculum of female extended broadly over apex of abdomen 4

4. Body slender, elongate, unarmed; no elytra Phasmatenionema

- Body elongate, spinose; elytra elongate-oval Achriopterini

5. Head swollen; middle and hind femora with tooth-like, Serrate inferior carinae. New Guinea Stephanacridini

- Head flattened; middle and posterior femora at most with few little thorns at apex. Australia Acauthomimini (Acanthomima)

6. Both sexes completely lacking organs of flight; median segment distinctly shorter than metanotum, usually much shorter 7

- Male alate; median segment of female almost or completely as long as metanotum Pharnaciini (Hermarchus)

7. Ceylon, India, Indonesia Baculini (Baculum)

- Australia, New Zealand Acanthoxylini (Arphax, Clitarchus)
