We take pleasure in naming Hypotrix naglei after Ray Nagle, a Lepidopterist who has graciously opened his home in the Santa Catalina Mountains for Lepidoptera research and where some of the type series was collected. Diagnosis. Hypotrix naglei is a small silvery-gray or brownish-gray species with the maculation sharply defined in back, and a contrasting pale-orange patch in the lower half of the terminal area on the forewing. Th e male genitalia are characterized by an elongated, narrow cucullus, an apically rounded digitus, and a mesially broad uncus tapered to a double-toothed apex. Th e female genitalia have a heavily sclerotized ductus bursae and relatively small corpus bursae and appendix bursae. Hypotrix naglei belongs to the second clade of the genus in which the cucullus is elongated, without a distinct “neck,” the digitus is apically spatulate, and the uncus is not usually apically spatulate. Description. Adults. Male and female similar in size, color, and maculation, except female hindwing averages slightly darker than for male. Forewing length: 11–12 mm. Head – Male antenna with individual segments very slightly swollen laterally; ventral setae with tendency to divide into two tufts on each side, becoming doubly bifasciculate apically. Female antenna filiform, minutely setose ventrally. Palpi and head clothed with slightly-forked, strap-like scales; appearing grizzled because of areas of Figures 40–45. Hypotrix female genitalia. 40 H. basistriga 4Ι H. naglei 42 H. alamosa 43 H. trifascia 44 H. optima 45 H. hueco. white, gray, and brown on scales. Thorax – Mainly covered with scales similar to those of head, but black-tipped scales form a transverse band on back of prothoracic collar, around tegulae, and on dorsal metathoracic tuft. Legs: Tibiae and tarsi mainly blackishgray with ring of white scales at apex of each segment. Tibiae without spiniform setae. Wings: Dorsal forewing gray or brownish gray; maculation sharply defined in black; basal, antemedial and postmedial lines black, distinctly double with pale-gray filling; medial line dark gray but diffuse and indistinct; postmedial line defined on anterior half of wing only by contrast between orange-brown shading in terminal area and gray in subterminal area; posterior half of subterminal line black and contrasting and dividing pale orange-brown shading in terminal area from gray subterminal area; wing margin with continuous black terminal line, slightly concave between veins; kidneyshaped reniform spot and rounded orbicular spot surrounded by black outline and filled with dark gray. Fringe with orange-brown scales basally, blending into dark gray scales distally. Dorsal hindwing pale fuscous with darker fuscous on discal spot, wing veins, postmedial line, and marginal 1/3 of wing; terminal line continuous, dark fuscous. Fringe a mixture of white and dark-fuscous scales. Male genitalia – Middle of uncus expanded laterally, tapered to double-toothed apex. Valve with elongated, tapered cucullus with only slight “neck” cucullus setose but no differentiated corona; digitus sclerotized, rounded apically, extending beyond ventral margin of valve anterior to neck of cucullus; clasper mainly straight, on inner surface of valve, abruptly upturned proximal to digitus; sacculus well-differentiated as a heavily sclerotized lobe on basal 1/4 of valve with membranous part of sacculus forming small flap overlapping sacculus and tapering to narrow area at ventral notch in valve. Aedeagus unarmed, very long and slender, about 10 × as long as wide and 0.8 × as long as vesica. Vesica basal swollen area with three sclerotized plates, each with short thorn-like cornutus in middle; short and stout, about 3 × as long as aedeagus; apical 2/3 of vesica curving in half coil and cluster of preapical spines. Female genitalia – Corpus bursae membranous, oval; appendix bursae only slightly longer than corpus bursae, partial coil at base; ductus bursae 1.3 × as long as corpus bursae with heavily sclerotized ridges and rounded mesial bulge on left. Anal papillae narrow and sharply pointed; base sclerotized, bulbous. Distribution and biology. Hypotrix naglei is known from east-central Arizona (White Mountains), southeastern Arizona (Pinaleno, and Santa Catalina Mountains), south-central New Mexico (Capitan and Sacramento Mountains), and southwestern New Mexico (Mimbres Mountains). Adults have been collected from mid-June to mid-July in open meadows in forests of aspen and pine.
