Phoberus disjunctus is a species of hide beetle in the subfamily Troginae discovered by coleopterologist Werner P. Strümpher in 2016.

[3] Within the genus Phoberus, P. disjunctus is most similar to P. capensis and P. herminae due to their shared evolutionary history, and historically researchers have often confused the three species for each other.

Specifically, its geographical distribution follows the Cape Fold Mountains, a pattern of range seen across many beetle groups in South Africa.

Rapid climate changes leading up to the ice ages likely prompted this evolution, as they affected hide beetle populations unequally.

In the mountains, the ancestors of P. disjunctus were isolated from P. capensis groups that had taken refuge in other patchwork biomes, leading to allopatric speciation (evolution from geographic separation).
