The first known fossils of the mite family Rhagidiidae, representing at least two species, are recorded from Baltic amber (Eocene). One of these is described as Zachardia flexipes n. gen. n. sp., which appears to differ from extant Rhagidiidae in having the femur of legs I and II divided into three segments. A second species is tentatively assigned to the extant genus Poecilophysis CAMBRIDGE, but the condition and probable immaturity of the single available specimen preclude a formal description.
