Advertisement A. australis australis, as the subspecies of A. australis, is the first confirmed valid species. As far as I konw, it was originally defined as a completely yellowish scorpion with no dark areas. The AA in the picture below seems AAA to me. Well, my current defination is that, AAA is completely yellow but appears orange in pedipalps and metasoma. Its vesicle is also reddish orange.
