Eupithecia phyllisae is a moth in the family Geometridae first described by Rindge in 1963. It is found in the US states of New Mexico and Arizona.
The length of the forewings is 7-8.5 mm for males and 7–9 mm for females. The forewing ground color is pale grayish white, heavily overlain with pale reddish-brown scales. The upper portion of the median area is broadly grayish black. The hindwings are concolorous with the forewings, but with a sinuate, grayish-black median band and a brownish-red extradiscal band, separated by a prominent stripe of the ground color.
Etymology
The species is named in honor of the wife of the author, Phyllis Rindge.
