We propose a conjectural formula for $DR_g(a,-a) \lambda_g$ and check all its
expected properties. Our formula refines the one point case of a similar
conjecture made by the first named author in collaboration with Guéré and
Rossi, and we prove that the two conjectures are in fact equivalent, though in
a quite non-trivial way.
