This literally the name of my A.Robustus. For the amount I mention these I only have 1 poor quality photo, so here is one of my 2 juvies. The males have an extremely high rate of envenomation with their bites, and 2 vials of antivenom are needed every 15 minutes depending on the symptoms
@Venom100 just looked them up and dayum they are a fine looking pair of spiders. Probably just ventrally through the gallery, or once they get to a certain size it's normally pretty certain that if they don't have male pedipalps, they are definitely female.
If they are anything like Hadronyche or Atrax, they are completely identical before maturing, their colouration leaves little room for any sexual dimorphism to show itself
