I can't see anything in that spider that says "female", maybe it is and will show more obvious signs later. But I don't see anything convincing in this photograph (of course everyone's got a 50/50 shot with any answer they give).
The two spots that I have circled tell me it is a girl.
The stripe has a very light break in it. Males keep a very dark almost completely black stripe. The carapace on most males have very little to no coloring on it. This one has a deep black looking carapace. Now it is not 100% but if I was to place money on it I would say female just by that.
To the OP if you do not want me to use your picture just pm me and I will remove it.
you have a female there male have a purple colour to them , look at this males carapace the females have a grey white colour not pinkie purple like males and the males show differant colours at around 2inch
