Local superderivations of Block Lie superalgebras $S(q)$

We prove that every even or odd local superderivation of the Block Lie superalgebra $S(q)$ is a superderivation for every $q\in\mathbb{C}$, with both basis indices ranging over $\mathbb{Z}$. The superderivations used in the local condition have the same parity as the map. The proofs use the known description of homogeneous superderivations, bracket computations, and coefficient comparisons.
