B. emelia are one of the trickiest to ventral sex in my entire experiences with T.'s. It's always a guessing game if there aren't good pictures, I can't guarantee you my guess. But i'd say "suspect" female. These guys are super easy to sex with molts because their spermathecae is already infused when young, compared to other brachys that infused later on in their maturity life. If you'll hear me out, males for these species are like non-existent now, I haven't seen a male B. emelia in sooo long. Male B. emelia are more sought out now by breeders than females.
