back to Identification Keys Identify Cerambycoid Family: 1/3 In general, members of the superfamily Chrysomeloidea (families: Cerambycidae, Chrysomelidae, Disteniidae, Megalopodidae, Orsodacnidae, Oxypeltidae, and Vesperidae) are phytophagous beetles which possess the following characters: antennae without club, pseudotetramerous tarsi, emarginate eyes, and cucujiform aedeagus. The four Cerambycoid families can be broadly defined as having the following characters: antennae generally long, antennae arising from raised tubercles, and pseudotetramerous tarsi.
