The Rivulinae are a subfamily of moths in the family Erebidae described by Augustus Radcliffe Grote in 1895.

Caterpillars in the subfamily typically have long, barbed hairs and have full prolegs on abdominal segments 3 through 6.

The adults have a unique microsculpturing[clarification needed] proboscis.

Recent phylogenetic studies did not discover a close relationship with the Hypeninae but keep it within the Erebidae.
