Diagnosis. The new species (Figs. 1–2) is externally similar to Stigmatophora roseivena (Figs. 3–4) and Stigmatophora (Pseudomiltochrista) zolotuhini (Figs. 5–6), but differs from S. roseivena by its slightly larger size, more angular forewings, and paler pinkish-yellow hindwings, whereas in S. roseivena forewings are more rounded and hindwings are pale red; from S. (P.) zolotuhini it differs by its significantly larger size, narrower and more angular forewings, broader red strokes on veins of forewings, red marginal area of forewings without submarginal transversal band, and paler, more yellowish hindwings, whereas in S. (P.) zolotuhini forewings are broader and with more rounded angles, the red strokes on veins of forewings are narrower, submarginal transversal band complete, the marginal area is yellow, and hindwings are more pinkish, with reddish suffusion on veins. The male genitalia of P. confusa (Figs. 7–8) principally differ from those of both externally similar species (Figs. 9–10).
Description. Adult (Figs. 1, 2). Length of forewing 10.5– 11 mm in males. Male antennae ochreous, finely ciliate. Head pale red with yellowish ochreous frons; tegulae yellowish ochreous, with pale red borders; patagiae yellowish ochreous, with pale red borders and medial longitudinal stroke; thorax yellowish ochreous with pale red medial longitudinal stroke; abdomen ochreous, with reddish suffusion dorsally. Forewing with arched costal margin. Forewing ground color bright yellow, pattern consists of pale red strokes along costal margin and all veins; terminal area pale red; cilia bright yellow. Hindwing ochreous yellow with slight pinkish suffusion; cilia ochreous yellow. Male genitalia (Figs. 7–8). Uncus long and narrow, laterally flattened, slightly curved, subdistally broadened and apically pointed. Tuba analis membranous, scaphium weakly sclerotized; tegumen short and narrow; vinculum very short, rectangular; juxta very broad, arrowhead-like, with rounded apex. Valve elongated and narrow, its distal half curved dorsally, costal margin with short and broad dorsal projection medially, apex with spine-like thorn. Sacculus narrow and short, reaching medial part of valve, with strong granulation and very short trigonal distal process with rounded apex. Distal half of valve curved dorsally, its ventral margin smooth, costal margin irregularly dentate; broad row of strong spine-like setae along ventral margin. Aedeagus elongated, distally curved and narrowed; vesica broad, with several bulbous membranous diverticula subbasally and medially, one broad elliptical diverticulum with granulation subapically, and one short and narrow apical diverticulum armed with long and narrow blade-like cornutus; basal plate of ductus ejaculatorius large, basally broad, heavily sclerotized. Female unknown.
Distribution. The species is known from East India (Arunachal Pradesh) (Kirti & Singh 2016), China (Sichuan, Hubei, Guangdong) (Dubatolov et al. 2012), North Vietnam.
Etymology. 'Confusa' means 'confused' in Latin. The specific epithet refers to its confusion with Stigmatophora roseivena.
