Pachycondyla Bulldog Ants

I see that the genus Hagensia is now in Pachycondyla.

According to Wiki :

Pachycondyla workers are similar to and easy to confuse with Cryptopone, Hypoponera and Ponera (other Ponerine genera).

Pachycondyla have a large comb-like and a smaller simple spur on the hind leg.

How does one tell the species apart and how many are there in the Cape Flora?

There are 28 genera and 1600 species worldwide of Ponerine Ants. But according to Wiki: expect lots of changes.

All Ponerines have a constricted abdomen (gaster) which makes them quite distinct from other ant subfamilies.

Ponerines in the Cape Flora

Our project has sites all over the Western Cape and we've found about 7 Ponerine species in the 8 years we've done sampling. I hope the following helps with telling the species apart (All of these were previously Pachycondyla):

Hagensia peringueyi
- big and black with a triangular petiole

Mesoponera caffraria
- has a rounded triangular petiole, is much smaller in overall size vs. peringueyi and is brown in colour

Bothroponera cavernosa
- has a pitted alitrunc with short white hairs allover and reddish appendages (legs, antennae, jaw)

Bothroponera granosa
- big, black and pitted allover
- yellow/goldish pubescent hairs covering the body with reddish/dark, short standing hairs allover
- eyes are smaller than pumicosa and its overall size is bigger (compared to cavernosa and pumicosa)

Bothroponera pumicosa
- small eyes but bigger than granosa
- pitted allover with reddish/gold hairs with reddish antennae
- the smallest in overall size when compared with granosa and cavernosa

Ophthalmopone hottentota
- large, black species with big eyes
- goldish pubescence allover and long mandibles
- rounded, rectangular shaped petiole

Restio

Please add the interaction: Not sure though that we can ID the restioid: any ideas Charles?
