A characterization of certain complex structures on conformally-flat domains in real dimension 4 is carried out in the context of Hermitian geometry and twistor spaces. The presentation is motivated by some classical surface theory, whilst the problem itself leads to a refined classification of quadrics in complex projective 3-space.

In this case, the Hermitian planar orthogonality can be transformed to non-Hermitian orthogonality on a contour due to a special identity [3, Lemma 3.1], and rigorous analysis is possible. The same identity was used in [22] in a study on moments of complex Ginibre matrices. the pine hanover
