Abstract
Calisius balticus, previously known from the Middle-Late Eocene Baltic amber, is recorded for the first time in the Lowermost Eocene French amber. It is the second case of an insect species present in both these two ambers, representing a morphological stasis of ca. 10 Ma. It is the oldest record of the genus Calisius. Aradus andancensis n. sp. in Upper Miocene sedimentary deposit from France is also described.
