When I first took these pics, I was pretty set on this one being male, but looking closer, it looks like spermatheca forming. It looks to me like there are the 2 "nubs" of geniculata spermatheca sticking up from the molt. The one on the left is definitely faint. I'm now really feeling female!
Actually I'm pretty sure it's a male. Yes, I see what you are seeing, but I think these are male accessory organs - the most common reason you get "molt sexed" females that turn out to be males (esp. likely in Phormictopus, but also in other species). Male accessory organs are significanly smaller than spermathecae, but you have a really big magnification here and those things are tiny, and I see no hint of an uterus externus, although that may develop later.
Still those things look like male accessory organs to me.
@boina I see your point but these still seem to scale to me.. I mean looking at the whole area the alleged spermathecae dont seem so tiny.. I really think this is female
@boina I thought male accessory organs dont get as tall/round looking as spermathecae. Also do they not only develope on the uper line of the furrow. Am I wrong? I havent read up much on them.
