Diagnosis. Antoniejanse reducta is recognizable by greyish-white forewing with distinct black tornal spot on 2/3 of dorsal margin and black irroration (as a resembling species, A. griseoptera differs in fold distinctly mottled with black and less distinct tornal spot). Both species can also be separate by segment 3 of labial palpus that is 1/2 length of segment 2 in P. reducta (about as long as segment 3 in A. griseoptera). The male genitalia are distinguished in deeply emarginated tegumen in A. reducta, along with glandiductor that is subequal in length to sacculus and juxta process (distinctly longer in A. griseoptera). The female genitalia of A. reducta with three signa are characteristic.

Redescription (Figs 5–7). Wingspan 8–10 mm. Head white with yellow shadow; labial palpus recurved, segment 2 brown with white apex and inner surface, segment 3 white with brown medial ring and 1/3 length of segment 2; scape white mixed with light-brown, flagellum light-brown; thorax and tegulae covered with white brown-tipped scales; forewing light-grey with brown suffusion along costal margin, in fold and in apical area, small brown spot in middle under costal margin, brown tornal spot on 2/3 of dorsal margin; fringes grey tipped with brown; hindwing and its fringes grey.

Male genitalia (Fig. 26). Uncus subtrapezoid, posteromedial incision slender; gnathos membranous; tegumen broad at base, distal part narrow, anteromedial emargination deep, triangular; glandiductor broad, narrowed apically; sacculus digitate, apex rounded; juxta process slender, elongate; phallus strongly curved in basal half, then straight, ventral margin weakly bulged before apex.

Female genitalia (after Janse 1958: pl. 3; 1960: pl. 60h, 74f, g). Papillae anales ovate, covered with hair-like setae; apophyses posteriores long, thin; sternum VIII twice broader than long, weakly sclerotized, unmodified; apophyses anteriores 2/3 length and slightly thicker than apophyses posteriores, apex broadened; ductus bursae long, slender; corpus bursae pear-shaped, signa as tree elongate sclerites.

Biology. Larval stages and hostplant unknown. Adults have been collected in August and November.
