Let $V$ be a $\mathbb{Z}_2$-graded vector space (aka super vector space) and $L(V)$ be the free $\mathbb{Z}_2$-graded Lie algebra (aka [super Lie algebra](https://en.wikipedia.org/wiki/Lie_superalgebra)). The free super Lie algebra is also graded by the number of generators (the generators $V$ sit in degree 1, and the Lie bracket itself has degree zero in this sense). So it has a decomposition by degrees, $L(V) = \sum_{n=1}^\infty L^n(V)$. The homogeneous components $L^n(V)$ may be called _(super) Lie powers_ of $V$ (by analogy with symmetric or alternating powers) and have an embedding $L^n(V) \subset V^{\otimes n}$, where the Lie (super)commutators are sent to tensor (super)commutators, $[a,b] = a\otimes b - (-)^{|a||b|} b \otimes a$. **Q**: What is the $\mathrm{GL}(V)$-representation theoretic description of $L^n(V)$? When $V$ is purely even (has no odd component), the question is answered by Klyachko's theorem (as explained in the answers to [MO187545](https://mathoverflow.net/q/187545)). So basically, I'm asking: What is the super Lie algebra analog of Klyachko's theorem? And what is a reference that clearly states it?
