Re-evaluation of the Prosopinae von Meyer, 1860 (sensu Glaessner, 1969) has resulted in placement of the included genera into two superfamilies, the Homolodromioidea Alcock, 1900, and Glaessneropsoidea Patrulius, 1959. The previously recognized Goniodromitidae Beurlen, 1932, and Tanidromitidae Schweitzer & Feldmann, 2008 [imprint 2007], are confirmed as belonging to the Homolodromioidea. New taxa recognized herein include four new families, Bucculentidae, Lecythocaridae, Longodromitidae, and Nodoprosopidae; four new genera, Abyssophthalmus, Bucculentum, Protuberosa, and Ver rucare inus; five new species, Bucculentum bachmayeri, Glaessneropsis myrmekia, G. tribulosa, Lecythocaris obesa, and Prosopon abbreviatum; and eight new combinations. Taxa are classified based upon a comprehensive array of characters including features of the orbits and rostrum; the nature and development of the carapace grooves; and the development of the dorsal and subdorsal carapace regions. A new term is defined, augenrest, for the concavity in the dorsal carapace or frontal margin of the carapace that lies distal to the orbit to house the eye. Recognition of two superfamilies for these taxa confirms the previous hypotheses of Feldmann et al. (2006), Schweitzer et al. (2007), and Schweitzer & Feldmann (2008 [imprint 2007]) that Jurassic Brachyura were much more diverse than previously recognized.
