A. geniculata - Brazilian White Knee - 35mm (1.3") DLS Male

Edited to confirm this is male
Looks like a male and what we're looking at is the gonopore and accessory organs.

Here's one of my females of a similar size for comparison:


 
@vicareux I see what you're saying. I'm unsure though as the only pic I can find of A. genic male accessory organs they look like tiny round nubs - https://arachnoboards.com/gallery/a-genic-juvenile.57566/ - whereas these are on stalks like snail eyes. I wish it was easier to find images of these things to compare.

Guess I'll wait for the next molt to be sure. At least it's a genic so I shouldn't have to wait long.

Hm, i do see what you mean by 'snail eyes'. I did not notice that. If i know what a spermatheca of a species looks like, and i see a '-' shape instead, i think male. This is interesting, post again once this one molts again. Take a look at my A.geniculata thread, where i posted multiple images of a spermatheca of 3 different specimen.
