The definition of the brachyuran genus Glyphithyreus Reuss, 1859 (= Plagiolophus Bell, 1858 non Pomel, 1857) is herein restricted such that the genus now embraces four species ranging from Paleocene to Oligocene in age. Other species previously referred to the genus have been placed in other genera, resulting in one new genus, Chirinocarcinus, and four new combinations, Chirinocarcinus wichmanni (Feldmann et al., 1995), Lobonotus sturgeoni (Feldmann et al., 1995), Stintonius markgrafi (Lorenthey, 1907 [1909]), and Titanocarcinus bitubercutatus (Collins and Jakobsen, 2003). The referral of Glyphithyreus to the Panopeidae Ortmann, 1893, extends the range of that family into the Paleocene. The geographic range of Stintonius Collins, 2002, is extended from England to include Egypt as well.
