Tefflus is a genus of large, black and flightless Afrotropical ground beetles in the tribe Panagaeini.

They are broadly similar to the Anthiini ('oogpisters'), but are not colourful, and have a six-sided and flattish pronotum.

The distinct longitudinal carinae (ridges) on their elytra are separated by two rows of punctures running along the striae (grooves).

They have strong mandibles that can inflict a serious bite, and prey on a variety of invertebrates.

Some 14 to 15 species are native to the Afrotropics:[2] Media related to Tefflus at Wikimedia Commons
