CH, CNC, CSUC, DNHC, LGC, TM. Differential diagnosis. Aseptis harpi (Figure 32) is most likely to be confused with Aseptis serrula (Barnes and McDunnough, 1918) (Figure 33) and Aseptis susquesa (Smith, 1908) (Figure 34). Both of these similar species are from the deserts of southern California, southern Nevada, and Arizona. Although neither species is known currently from Utah, they could potentially occur with A. harpi near the Arizona-Utah border. Figures 32-34. Aseptis adults. 32 A. harpi , male, USA, Utah, San Juan County, 1.6 km N of Bluff, 33 A. serrula male, USA, Arizona, Maricopa County, Cave Creek 34 A. susquesa , male, USA, Arizona, Mohave County, Wikieup 9 km WSW. DNA barcodes suggest that A. serrula is the closest relative to A. harpi . Males are distinguished easily because the antenna of A. harpi is filiform, whereas that of A. serrula is serrate. Aseptis harpi has a lighter, more mottled, and more colorful forewing than A. serrula , with patches of pale gray and orange tan rather than powdery dark gray. The hindwing of A. harpi is gray distal to the postmedial line, whereas the entire hindwing of A. serrula is whitish. Superficially, Aseptis harpi most closely resembles Aseptis susquesa . Both species have narrow male antennae and forewings with patches of orange brown. The forewing spots and postmedial and subterminal lines of A. harpi are more sharply defined and conspicuous than in A. susquesa . Pale filling of the postmedial line and whitish "W" marks of the subterminal line on veins below the apex and on M3 and CuA1 are particularly prominent in A. harpi . Hindwing color differences between these species are similar to those between A. harpi and A. serrula . The male genitalia of A. harpi (Figure 35), A. serrula (Figure 36), and A. susquesa (Figure 37) are similar. The angle between the digitus and the valve is narrower in A. harpi than in the others, approximately 30° in A. harpi compared to nearly 50° in the other species. The digitus of A. harpi extends a shorter distance below the valve than in the other species. Females of can be identified by characters of the papillae anales. The papilla analis of Aseptis harpi (Figure 38) has a single short apical process and lacks long basal setae. That of Aseptis serrula (Figure 39) has a finger-like apical process with adjacent scale-like tubercles and a dense basal collar of long seta. Aseptis susquesa (Figure 40) lacks an apical process and has few very long setae at the base. The appendix bursae of A. harpi is longer than those of the other two species. The barcode of A. harpi (BOLD:ADH0685; n = 2) differs from those of A. serrula and A. susquesa by approximately 5 %. Aseptis harpi and A. serrula form a sister pair closest to Aseptis catalina (Smith) on a similarity tree. Major haplotypes of other Aseptis species are listed in Mustelin and Crabo (2015 : 59-60).

Etymology . The eponym honors Chuck Harp of Littleton, Colorado who recognized this moth as an undescribed species and brought it to our attention. Most of the known specimens of this species have been collected by him. Distribution and ecology. Aseptis harpi has a limited range in eastern and southeastern Utah (Figure 48). It has been collected in the red rock country of Garfield, Grand, and San Juan counties. The habitat is shrub steppe. Collection dates are from May and early June. The early stages are unknown. The larva is probably a climbing cutworm that feeds on woody shrubs based on the habits of other Aseptis species ( Mustelin and Crabo 2015 ). Discussion. The discovery of this species is a surprise to us since we revised Aseptis recently ( Mustelin and Crabo 2015 ). No new species were recognized at the time, although two new genera were described and the number of recognized species was reduced significantly.
