Distribution. Taiwan (Fig. 19).

Remarks. The species can be recognized by the dull green head, pronotum (partly with copper red in females) and scutellum; the dense rugosity on the pronotum and scutellum; the absence of a lateral setose spot on the disc of the pronotum. Also, the major hook of the internal sac is always with a lateral denticle (Fig. 18) thereby distinguishing E. cupreipes from all allied species from mainland China and Indochina. Adults are active from March to August in the low elevation montane areas of Taiwan below 1500 m in elevation (mostly under 1000 m) and feed on the flowers of trees, shrubs or herbs without any specific preference.
