Diagnosis. Rejectaria magas is most similar in appearance to R. richardashleyi sp. n., below, and to Bleptina albidiscalis . Rejectaria magas shares most of the wing pattern elements of R. richardashleyi but can be differentiated from both species by the paler tannish-brown (as opposed to dark brown) coloration, and can be further differentiated from richardashleyi by the lack of large hind-femoral tufts. The valva is similar to that of richardashleyi with sclerotization confined to the basal half of the costa and no free protrusion at the valva’s terminus, but with a minute protrusion at the terminus of the sclerotized basal part of the costa. The female genitalia share a distinctly configured band of signa with ritaashleyae , villavicencia , and villosa but with fewer (12–13) toothed discs than the latter two species.

Supplement to original description. Head. Vertex and collar mixed with beige and cream-colored scales; antennae setose-ciliate; male palpi missing from specimen examined; female palpi ( Fig. 39 View FIGURES 39–42 ) with 2 nd segment nearly straight, 3 rd segment fine, ~half as long as 2 nd, closely scaled with beige at each end, with an uneven band of larger, gray scales in the middle.

Thorax. Wings— (male, 20mm, n=1; female 18mm, n=2). Male costa distinctly tan, concolorous with collar, darker brown shading concentrated beneath costa towards base; FW and HW tannish brown overall, paler between pm and st lines; basal line absent; FW am line wavy, shaded brown outwardly, paler inward; pm line straight, inwardly a diffuse dark brown band, outwardly a more sharp, tannish brown line, angled inward near costa; subterminal band a series of brown dashes tipped outwardly pale; terminal line a series of fine black dashes. FW pattern recapitulated on HW. Legs— ( Fig. 39 View FIGURES 39–42 ) Male forefemoral tuft present; legs uniformly tannish brown, with bands faint, if present.

Abdomen. Tannish-brown, concolorous with uppersides of wings

Male genitalia. (Fig. 55,81–82) Uncus elongate, setose, sheepsfoot-shaped; costal margin sclerotized in basal half, entirely fused with valva except for minuscule terminal nubbin comparable to but smaller than that in villavicencia ; outer margin of valva rounded; vinculum bluntly tapered; small phallic ridge present; vesica multilobate; microspines distributed on phallus at base of vesica, concentrated on subbasal lobe and more diffusely throughout lower vesica.

Female genitalia. ( Fig. 93 View FIGURES 93–94 , 99 View FIGURES 95–102 ) Ductus bursae with broad sclerotization along most of its length; corpus bursae swollen near junction with ductus; appendix bursae partially coiled but not whorled as in villosa ; corpus bursae with mid-ventral band of micro-spinules well-developed ( Fig. 99 View FIGURES 95–102 ), punctuated by a series of 12-13 internal perpendicular ridges as in villavicencia , villosa , richardashleyi , and ritaashleyae ; faint secondary band includes faint internal ridges, appearing to echo primary band.
