Abstract: The micropezid subfamily Eurybatinae is reviewed to include 33 species in the Australian region, 45 species in the Oriental region, one species in the Afrotropical region and two species in the Neotropical region. The subfamily is redefined to exclude the Metopochetini, and 20 of the 81 species in the subfamily are newly described. Phylogenetic trees are provided on the basis of molecular data from 26 species of Eurybatinae, representing eight genera. Eurybatinae (excluding Metopochetini) are recovered as monophyletic and sister to Taeniapterinae in all analyses. The subfamily can be arranged into two groups according to the presence or absence of a sclerotized postmetacoxal bridge. Most analyses recovered the “postmetacoxal bridge” group as monophyletic. This group, including Crosa Steyskal, Nestima Osten Sacken and Papeza McAlpine, is fully revised herein. The remaining members of the subfamily, which lack a sclerotized postmetacoxal bridge, fall into the following seven genera: Anaeropsis Bigot, Cothornobata Czerny, Crepidochetus Enderlein, Eurybata Osten Sacken, Notenthes Marshall, Paraeurybata Marshall and Trepidarioides Frey.
