Disteniinae
disteniid longhorn beetles
Disteniinae is a subfamily of longhorn beetles (Cerambycidae) comprising approximately 400 described species, primarily distributed in tropical and subtropical regions of the Americas. Adults are characterized by their elongated, slender bodies, long filiform antennae that often exceed body length, and frequently metallic coloration. The group has undergone significant taxonomic revision, having been treated historically as a tribe within Lepturinae or Cerambycinae, as a separate subfamily, and even as a distinct family (Disteniidae) before current consensus places it as a subfamily within Cerambycidae. The North American fauna is depauperate, with Elytrimitatrix undata being the sole representative in the United States.
