Bersta is an extinct genus of hemipteran in the monotypic family Berstidae.

[1] The genus is named after Berstuk, a shapeshifting Slavic forest deity of the Sorb and Wend peoples.

[1] The authors of the describing paper stated that the morphology strongly resembled those of beetles belonging to the families Tenebrionidae, Trogossitidae and Nitidulidae.

They proposed the Bersta could have been an aggressive mimic, using its morphology to fool potential prey by resembling them.

[1] A phylogenetic analysis found the genus to be a member of Miroidea, and the sister family to Tingidae.
