Etymology.

Paul Dognin likely name this species arbosioides in reference to its similarities to Gaujonia arbosi , which was described previously.

Diagnosis.

Millerana arbosioides is closely related to three species: M. austini , M. cajas , and M. cundinamarquensis ; however, M. arbosioides can be recognized by the black antenna and haustellum. Forewing length in males is 16-18 mm. Millerana arbosioides shares more external characters with M. cundinamarquensis , but it can be distinguished from it by the antemedial line, which is well developed in M. arbosioides , the reniform spot is better defined, and the lunate marking is small; these features in M. cundinamarquensis are barely visible, but it presents four black tufts in the middle of 1A-4A, whereas M. arbosioides has three on A1-3A. The genitalia in M. arbosioides have a semi-squared cucullar area and some protuberances in the outer margin that are present in M. tigrina and M. cajas as well however, both species differ from M. arbosioides by their apexes that are rounded and their outer margins of the cucullar area, which are straighter.

Immature stages.

Unknown.

Distribution.

The species is known only from coniferous forests in Ecuador at very high elevations ca. 2500-3500 m (Fig. 94 ).

Biology.

Unknown.

Remarks.

One of the additional examined specimens was in very poor condition and only identifiable by genitalia examination.
