Polyzosteria yingina is a bush cockroach (a member of the Blattidae family) found only in Tasmania.

[1] It was first described in 2020 by Shasta Henry and others.

[1][2] This species consists of two very distinct populations: one an alpine population found 1000 metres above sealevel and the other found at sealevel on Tasmania's east coast.

Mitochondrial molecular analysis indicates that these two populations are a single species.
