Identification

Currently this species cannot be assigned to any of the species groups within the genus. From all species described from late Eocene European ambers, D. jonasi is characterized by the presence of pronotal teeth and the structure of the propodeum. Similar structure of the propodeum (presence of a chitinous ridge or ridge along the posterior edge of the main surface) was noted in species of the group D. balticus, but they have the main surface of the propodeum more convex, lacking a number of large setae along its posterior margin and no spines on pronotum. This species is similar in a number of ways to representatives the D. bidens and D. bispinosus + debilis + laminatus complexes (former genus/subgenus Monacis), living in South and Central America.

Distribution

This taxon was described from Rovno amber, Baltic Sea region, Europe (Priabonian, Late Eocene) and Baltic amber, Baltic Sea region, Europe (Bartonian, Middle to Late Eocene).
