Rivulinae
Rivulinae is a subfamily of moths in the family Erebidae, established by Augustus Radcliffe Grote in 1895. The subfamily is characterized by distinctive larval and adult morphological features: caterpillars possess long, barbed hairs and retain full prolegs on abdominal segments 3 through 6, while adults exhibit a unique microsculpturing proboscis. Taxonomic placement has been revised; Rivulinae was formerly classified within Hypeninae or Noctuidae but is now retained in Erebidae based on phylogenetic studies. The subfamily includes approximately 8 recognized genera, with members distributed across multiple continents.
