anticonformal mapping

An indirectly conformal mapping, sometimes called an anticonformal mapping, is a mapping that reverses all angles, whereas an isogonal mapping can reverse some angles and preserve others. For example, if w = f(z) is a conformal map, then (f(z))^_ is an indirectly conformal map, and f(z^_) is an isogonal mapping.
