Taxonomic Notes:
This informal genus-group is used here for the group of genera related to Cypa identified by Kitching & Cadiou (2000: 17) as forming a putatively monophyletic group. Unfortunately, none of the included genera were studied by Kawahara et al. (2009) and the monophyly of the group remains to be demonstrated. At present, the only (rather weak) diagnostic character is the presence of a fan of scales covering the ventral part of the eye.
