Based on the shape of the digging claws Im inclined to say is Neocurtilla hexadactyla. If you look at the second picture in the series, you can see that there are distinctly four claws arrayed in a row, which to my knowledge is typical of Neocurtilla.

I also beleive that in the Southern Mole Cricket, the wings almost fully cover the abdomen

This is definitely Neocurtilla hexadactyla; the distalmost branches of vein Sc in the tegmen point back towards the wing base. This is one of the defining characters of the genus Neocurtilla; in Gryllotalpa all the Sc branches point towards the tegminal apex.

Both Gryllotalpa and Neocurtilla have four protibial dactyls, though Scapteriscus has only two.
