The easiest way to tell Missulena and Atracidae apart is the eye arrangement. Missulena eyes will be spread across the caput region of the cephalothorax (top of the head area next to the chalicerae), while Atracid eyes will be tightly grouped together. Missulena have a more stocky appearance compared to Atracids and they have much more chonkier looking Chalicerae (the large appendage at the front of the head where the fangs attach to the body).
I'd be happy to help if you have any further questions
