Need ID on hisser roach

[Moose9]

I just received these hissing roaches but don't know what species they are. The adults are a dark brownish to black in color and about 3" in length. Any help would be appreciated.

You can see a few more pics here!

Thanks,
Greg

This is a typical female Gromphadorhina portentosa. Aka "normal hisser".

Cheers.

p.s.- just about all the hissers out there are G. portentosa with few exceptions.
