Wappesia gen. nov.

Type species: Tethlimmena gahani Gounelle, 1911 .

Description. Head with well-marked median groove, reaching level of upper eye lobes. Pronotum with six tubercles, (antero- and posterolateral subfused): anterolateral tubercles delimited by sulcus at anterior margin; posterolateral (the largest) posteriorly delimited by sulcus that extends to inner side; anterocentral tubercle elongate, placed near anterior margin; and posterocentral tubercle elliptical, placed between posterolateral tubercles. Sides of prothorax with two tubercles, one centrally, another near anterior margin. Elytra covering or almost covering abdomen, slightly widened toward apex; without humeral carina; surface coarsely punctate; with slightly sinuous apex. Metatibiae slightly arched.

Female: Unknown.

Etymology. The generic name is in honor of our late friend James E. Wappes (1944–2021). Feminine gender.

Remarks. Júlio (1997) provided a key to species of Oxycoleus, which already indicated this genus was composed of two genera, except for the shape of the antennomeres (translated): “1. Elytra with carina; antennomeres cylindrical;” “Elytra without carina; antennomeres compressed.” However, the wide and sinuous shape of the elytral apices, easily separates Wappesia from others related genera.
