Peleserphidae is an extinct family of wasps belonging to the superfamily Proctotrupoidea.
It is currently known from four species in three genera.
One (Arkadiserphus) from the Middle-Late Jurassic Karabastau Formation of Kazakhstan, and the others (Peleserphus and Peleproctus) from mid Cretaceous Burmese amber from Myanmar.
[1][2] They are suggested to have targeted hosts hidden in substrates like wood, such as insect larvae.
