How To sex Neurergus kaiseri?

Can anyone explain to me the best method for sexing these guys. I am pretty sure I have 2 females. I know for fact that one is a female 100%. But I am thrown in a loop on the other one all tho they both look the same. I think I may need to look for a Adult male.

They're not the easiest species to sex. Adult females in good condition are heavier-bodied than the males. males cloaca is also more swollen than the females while breeding, but I personally don't find this completely reliable in this species. Also, females lay eggs, males display and "fan" at the females ;-)
