Antenna composed of 19 or more antennomeres. Pronotum smooth and flat. Anterior margin of the pronotum obtusely triangular, not spine-like and not projected above the head.

Type genus. -

Rusmithia Skejo, Kasalo, Thomas & Heads, gen. nov.

Composition. -

Two genera ( Danatettix and Rusmithia ), two species. Danatettix hoffeinsorum Thomas, Skejo & Heads, 2019 and the herewith described Rusmithia gorochovi Skejo, Kasalo, Thomas & Heads, gen. et sp. nov. Enigmatic Acrydium bachofeni (Zeuner, 1937), characterized by long wings ( Zeuner 1937) might also belong to this tribe as well as the genus Succinotettix Piton, 1938 (with one species, S. chopardi Piton, 1938) whose antennae are reported to have at least 19 segments ( Piton 1938). However, we refrain from transferring these genera to Rusmithini as we were unable to examine the type specimens.
