Tobochares luteomargo species group

Diagnosis.

Members of this species group can be recognized by the straight anterior margin of the eye in lateral view (Fig. 2E ), the longitudinally aligned and undifferentiated elytral punctures with about the same size and degree of impression (Fig. 5A ), the short and narrow glabrous patch on the metaventrite (Fig. 5C ), the scantiness of the hydrofuge pubescence on the abdominal ventrites (Fig. 5C ), and the reduced (in number and size) metatibial spines.

Composition.

This species group currently contains only a single species, T. luteomargo sp. nov.
