@boina is this a male?

I think I can see clear spermathacae, but it's a little hard to tell

Yes, I'd go with male on this one. @jaycied the structures you see look much more like male accessory organs than spermathecae. They are very far apart and there's no uterus externus ('flap') between them. The light colored, half moon shaped structure in the middle, on the other hand, looks like a field of epiandrous fusillae.
