Skejo, Josip, Kasalo, Niko, Thomas, M. Jared & Heads, Sam W., 2024, A new long-winged pygmy grasshopper in Eocene Baltic amber raises questions about the evolution of reduced tegmenula in Tetrigidae (Orthoptera), Journal of Orthoptera Research 33 (1), pp. 21-26 : 21

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

Type species. -

Rusmithia gorochovi sp. nov.

Diagnosis. -

Antenna with 20 segments (or more, some articulations between antennomeres are not clear). Tegmenula extremely long (for a member of Tetrigidae ), reaching the mid-length of the hind femur.

Composition. -

A single species, Rusmithia gorochovi Skejo, Kasalo, Thomas & Heads, sp. nov., described herein. Acrydium bachofeni (Zeuner, 1937) may also belong to this genus if the long tegmenula (5 mm in length), cited in the original description, are taken into account ( Zeuner 1937). However, the type of A. bachofeni has not been examined by us, and we are unsure of its location.

Etymology. -

The new genus-group name is patronymic and honors Dr. Ru Smith, who kindly made the important specimen available to science. The name is feminine.
