Polia tristis Barnes & McDunnough, 1910: 152 .

Type material. Holotype ♁. USNM, examined. Type locality: USA, Arizona, [Cochise Co., Miller Canyon ], Palmerlee.

Other material examined and distribution. Mexico: State of Durango (Sierra madre Occidental) . USA: Arizona: Apache Co. (White Mts), Cochise Co. ( Chiricahua amd Huachuca Mts ) ; New Mexico: Catron Co. (Mogollon Mts), Colfax Co. ( Sangre de Cristo Mts ), Grant Co. ( Pinos Altos Mts ), McKinley Co. ( Zuni Mts ), and Socorro Co. ( San Mateo Mts ) .

Diagnosis. Anhypotrix tristis can be recognized by the blackish-gray and pale gray streaked forewing pattern. Th e streaked appearance is enhanced by the strongly zigzagged antemedial line and a deep V-shaped notch in the postmedial line with a black bar connecting it to the antemedial line. Th ere is also a black basal dash and a black and white patch near the anal angle of the wing, this latter patch giving the moth the appearance of a large (forewing length: 15–18 mm) Lacinipolia McDunnough. In many specimens there is some brown shading on or beyond the reniform spot, below the orbicular spot, and near the anal angle. Th e hind wing in males varies from dirty white (e.g., Fig. 18), to entirely fuscous, with dark-fuscous on the veins, postmedial line and wing margin. Th e hindwing in females averages darker than in the males. The male genitalia are best recognized by the massive ventral clasper, the tapered uncus, and the form of the vesica and the female genitalia by the rounded anal papillae and shape of the bursa copulatrix.

Distribution and biology. Anhypotrix tristis occurs from eastern Arizona and northern New Mexico southward in the Sierra Madre Occidental to the State of Durango in Mexico. Adults have been collected in conifer forest habitats from early May until early August.
