Habitus Fig. 16 View FIGURES 13–20 , 27. Male genitalia Fig. 54 View FIGURES 51–56 , 77–78 View FIGURES 73–80 .

Narcaea atrax Dognin, 1891 , Le Naturaliste 13: pp. 125–126. Type locality: Ecuador: Loja (Holotype ♂, USNM)

Material examined. Type material: Narcaea atrax Holotype ♂. Ecuador: Environs de Loja Equateur SJ., Narcaea sp. n. “I have described the genus in the Biologia, Narcaea atrax Dgn , type, type figure 1894, Dognin Collection”, Type No. 32294 U.S.N.M., USNMENT00973692, USNM slide 148640

Diagnosis. Rejectaria atrax and R. splendida are differentiated from other species by the presence of fine, white, entire am and pm lines on the forewing, the absence of frosting in the median field, and the presence of chalky-white patches in the postmedian field. Rejectaria paratrax lacks whitish frosting and R. ritaashleyae lacks an am line.

Supplement to original description. Head. Frons, vertex dark brown; male antennae setose-ciliate; male palpi (Fig. 27) predominantly brown with scattered white scales, overall shape squared, the 1 st and 2 nd segments forming right angles, 1 st segment turning upward at a 90˚ angle before meeting the 2 nd segment; 2 nd segment curving gently for most of its length before turning sharply backward, well above the head. Everted hair pencils tannish.

Thorax. Wings ( Fig 16 View FIGURES 13–20 )—(male, 24.5, n=2) FW with dark brown median field, heterogeneous pale frosting in basal and postmedial fields, frosting in the postmedial area concentrated in the subapical patch and towards the pm line where it meets the inner margin; st line faint a discontinuous series of white markings, terminal line a series of white dashes; finge brown; pm, st and terminal lines continue on HW. Legs ( Fig. 31 View FIGURES 31–38 ) — (Fig. 27) Predominantly chocolate brown, male foretibia cream-colored laterally; pronounced chocolate-brown tuft with scattered white scaling; female foreleg and midleg with additional white scaling at segments; incomplete cream-colored segmental bands on legs and at base of tibial spurs.

Abdomen. Gray-brown above, concolorous with hindwing uppersides.

Male genitalia. ( Figs 54 View FIGURES 51–56 , 77, 78 View FIGURES 73–80 ) Indistinquishable from splendida (below); valva also similar to that of paratrax in having uneven (as opposed to smooth) outer margin.

Female genitalia. Unknown.

Immature stages. Unknown.

Biology. Unknown.

Distribution. Ecuador

Remarks. The male holotype of atrax from Ecuador may be conspecific with the Costa Rican syntypes of splendida based on habitus and genitalia, but since no other specimens are available for comparison and there are neither barcode nor larval data available, we have chosen to maintain both names.
