description: <i>Hypotrix alamosa</i> (Barnes, 1904), comb. n. Figs 10, 11, 27, 42 <i>Taeniocampa alamosa</i> Barnes, 1904: 201. <b>Type material.</b> The species was described from a male and a female in USNM. Type locality: USA, Arizona, Huachuca Mts. Th e female is in better condition and represents the more common dark form, so it is here designated as <b>lectotype</b>. It is labeled “ <i>Taeniocampa alamosa</i> type &amp;female; Barnes/ Huachuca Mts. Ariz./ Photograph Pl. VI No. 18 [green printed label with “VI” and “18” hand written in black ink]/ Barnes Collection.” It is in good condition except that the antennae are missing. <b>Other material examined and distribution. USA:</b> Arizona: Cochise Co. (Chiricahua and Huachuca Mts), Pima Co. (Santa Catalina Mts), and Santa Cruz Co. (Santa Rita Mts). <b>Diagnosis.</b> <i>Hypotrix alamosa</i> (forewing length 14–16 mm) occurs in two forms. In the darker, more common form (Fig. 10) the forewing is reddish brown with the <b>Figures 46–48.</b> <i>Hypotrix</i> and <i>Anhypotrix</i> male genitalia. <b>46</b> <i>H</i>. <i>lunata</i> <b>47</b> <i>H</i>. <i>purpurigera</i> <b>48</b> <i>Anhypotrix tristis</i>. maculation sharply defined by dark-red lines. Th e medial area is similar in color to the remainder of the forewing and the postmedial line touches, or almost touches, the reniform spot. Superficially this form is most similar to <i>Hypotrix hueco</i> (see under <i>H</i>. <i>hueco</i>) and <i>Xestia bolteri</i> (Smith), both of which occur with <i>H</i>. <i>alamosa</i>. It differs from <i>Xestia bolteri</i> in that <i>H</i>. <i>alamosa</i> has smaller reniform, orbicular, and claviform spots, and in lacking spiniform setae on the tibiae; <i>Xestia bolteri</i> is illustrated in Lafontaine 1998. Th e pale form of <i>H</i>. <i>alamosa</i> looks like the specimens have been bleached, so the forewing is light orange with the maculation weakly defined by fine yellow lines. Th e dark and light forms frequently occur together and the two syntypes of <i>H</i>. <i>alamosa</i> represent a specimen of each form. The <i>male genitalia</i> differ from those of other species in many features: the valves are tapered from the base to apex a slightly indented “neck” at the base of the triangular cucullus; the sacculus is very large with a rounded lobe projecting from the dorsal margin and the membranous saccular flap overtops almost the entire sclerotized part; the digitus is wide and truncated apically; the apical half of the uncus is broad and spatulate; the vesica has a mass of cornuti near the apex of the aedeagus, and the apical part of the vesica has four tight coils. In the <i>female genitalia</i> the appendix bursae has four tight coils, corresponding to those in the vesica, and the ductus bursae is heavily sclerotized with a prominent posterior bulge to the left. <b>Distribution and biology.</b> <i>Hypotrix alamosa</i> in known only from southeastern Arizona. Collecting dates range from early June to mid-July and early to late September.
