Bostra and Clonistria, belonging to Bacunculides, have the median segment almost as long as the metanotum.
The American genera Pterinoxylus, Haplopus, and Candaules, as well as the African Palophus, possess winged females.
The African and Australian genera Orobia and Paraorobia, although they have a short median segment, are placed in the tribe Phasmides of this division.
This character is evidently erroneous as regards the males of the genus Phyllium.—D. S.
