Etymology. Rubra is taken from the Latin for red and refers to the reddish color of the forewings and body of the moth.

Diagnosis. Hypotrix rubra can be recognized by the reddish-brown forewing with the maculation obscure except for a diffuse reddish-brown medial line that is sharply

angled at the reniform spot, a dark-gray spot in the lower part of the reniform spot, and an almost straight red subterminal line. It is most closely related to H. parallela , both species having similar male and female genitalia with a bulbous cornutus on a submedial diverticulum in the vesica. They differ in that H. rubra lacks spiniform setae on the middle and hind tibiae, the uncus is much broader apically, the cucullus extended farther ventrally, and the vesica in the male and appendix bursae in the female are correspondingly longer.

Description. Adults. Male and female similar in size, color, and maculation. Forewing length: 12–16 mm. Head – Male antenna with individual segments swollen laterally, slightly diamond-shaped; ventral setae with tendency to divide into two tufts on each side. Female antenna filiform, minutely setose ventrally. Palpi and head unicolorous, clothed with deeplyforked, reddish-brown scales. Thorax – Covered with deeply-forked, reddish-brown scales; without tufting. Legs: Covered with reddish-brown scales with scattered dark-gray scales, especially on outer side of tarsi. Tibia without spiniform setae. Wings: Dorsal forewing reddish brown (occasionally reddish-gray) with maculation obscure except for a diffuse red medial line, sharply angled at reniform spot, a dark-gray spot in lower part of reniform spot, and an even, slightly concave red subterminal line; some specimens with patch of gray scales near apex of wing. Fringe similar to forewing ground color, or slightly darker red. Dorsal hindwing dirty white or very pale fuscous with darker fuscous on discal spot, wing veins, and wing margin. Fringe pale reddish buff with diffuse darker medial line. Male genitalia – Uncus gradually widening from base, then abruptly expanded and wedge shaped at apex. Valve with well-defined triangular cucullus with narrow “neck,” dorsoapical corona, and one stout seta at protruding anal angle; digitus short, tapered and lightly sclerotized, projecting into base of ventral notch proximal to cucullus; clasper a slightly upcurved rod extending to dorsal margin of valve; membranous part of sacculus extends along ventral half of valve to notch anterior to cucullus; lower margin of valve evenly curved into notch. Aedeagus with cluster of small spines at apex on right side. Vesica very long and gently coiled, about 6 × as long as aedeagus; vesica swollen at base with 16–18 long stout cornuti forming longitudinal row along swollen area and transverse row across middle of it; cornutus with bulbous base on a short diverticulum at about 1/5 from base of vesica. Female genitalia – Corpus bursae membranous, rounded; appendix bursae long, narrow, and coiled, about 3 × as long as corpus bursae. Ductus bursae about as long as corpus bursae, heavily sclerotized on sides, more so on left side. Anal papillae narrow and sharply pointed with large bulbous base.

Distribution and biology. Hypotrix rubra occurs from southwestern New Mexico and southeastern Arizona southward to the State of Durango in northern Mexico. Adults have been collected between early May and early July in ponderosa pine forests and mixed woodlands of pine and oak.
