Observations.

The new combination for I. ferruginea would be Zethus ferrugineus , which is a secondary junior homonym of Zethus ferrugineus de Saussure, 1852, which is a junior synonym of Zethus biglumis Spinola, 1841. Therefore, a new name has to be proposed.

Etymology.

The new name follows the intention of the name it is replacing, an epithet referring to color, which translates to a yellowish red.
