The Trictenotomidae are a small family of beetles in the superfamily Tenebrionoidea, containing fifteen species in two genera.

The family is considered, based on larval characters as well as sequence-based studies,[1] to be closely related to the Salpingidae.

[2]Adult Trictenotomidae can be mistaken for Cerambycidae (Prioninae) or Lucanidae but their 5-5-4 tarsal formula makes them distinctive.

Adult beetles are attracted to lights and specimens are found widely in collections around the world however very little was known of their life-history until the habits of Trictenotoma formosana were studied in captivity in Taiwan in 2019.

Based on that species, these are thought to breed in wood, the eggs being laid under bark.
