The presence of a large pair of coremata just distal to the eighth
segment in the male abdomen appears to be the most constant feature for
this tribe, though the occurrence of a calcar (see Xanthorhoe Hübner)
is an additional diagnostic feature that is characteristic of many of the
component species. Coremata are generally absent in the sister-tribe, the
Cidariini (following), but do occur in some Ecliptopera Warren.
Patocka (1995) has described pupal characters in the tribe.
