Based off Whyte & Anderson (2017) I think it's a male A. ergandros. It's very white with an indistinct abdominal pattern so I don't think it's A. cruentata. There seems to be limited freely available information though. If you have access (Unfortunately I don't at the moment), the following might be a good source to explore! https://bioone.org/journals/annales-zoologici/volume-64/issue-3/000345414X684795/Revision-of-Australian-Species-of-the-Genus-Diaea-Araneae/10.3161/000345414X684795.short
