Diagnosis. Thaumatotibia salaciae is superficially similar to Cryptophlebia illepida (Butler, 1882) and C. ombrodelta (Lower, 1898) with a distinct dark brown to rust brown triangular pretornal spot on a grayish to grayish brown or brown ground color. However, males of T. salaciae can be distinguished from those of all species of Cryptophlebia and Thaumatotibia by the presence of a narrow pouch of modified sex scales near the distal end of the discal cell in the hindwing, represented by a small ovoid swelling on the upper surface and by a narrowly open pouch bearing blackish scales on the lower surface (Fig. 41). The male genitalia of T. salaciae differ from those of all other described congeners in the presence of a group of enlarged spines at the outer edge of the sacculus and the extremely long, slender phallus.

Description. Male. Head: Vertex blackish brown and ferruginous; frons pale ferruginous; labial palpus blackish brown on outer surface, whitish on inner surface, length ca. 1.3 times horizontal diameter of compound eye. Thorax: Notum blackish brown and ferruginous, distal end of tegula steel gray; hindtibia in male slightly swollen by cream colored secondary sex scales. Forewing length 6.5 mm (n = 1); forewing expanding distally, termen straight; ground color grayish, costal area and basal 0.33 of dorsum mixed ferruginous and dark gray, basal area blackish brown; faint, narrow, cream patch along dorsum before middle; striations dark gray in posterior 0.33; subterminal fascia slender, ill-defined, ferruginous at costa, dark gray below; pretornal patch triangular, rust colored; costal strigulae fine, whitish, divisions rust; fringe ash gray. Hindwing pale brownish gray with darker striations; a small oblong pouch of scales near distal end of discal cell at intersection of veins CuA1 and M3, slightly elevated and concolorous with wing on upper surface, black scales concealed in narrowly opened pouch on lower wing surface (Fig. 41); fringe much paler than ground color. Abdomen: Male genitalia ( Fig. 23 ) with tegumen relatively broad, subrectangular; uncus, socius, and gnathos absent; basal half of valva broad; cucullus subtriangular, hairy, sacculus ending before middle of valva, with distinct angle bearing a patch of short, strong spines; ventral incision large, semicircular; cucullus subtriangular, densely spined/hairy along ventral margin; phallus very slender, long, strongly curved proximally.

Female. Head and thorax: Essentially as described for male [although in very poor condition]; forewing length 7.0 mm (n = 1); lacking pouch of sex scales on hindwing; frenulum with two bristles. Abdomen: [Missing].
