Figs. 3, 4 , 10 , 15 Diagnosis. The male and female genitalia of this species differ from those of other species of Loboschiza by a pair of nipple-shaped projections possibly representing uncus and the spiniform setae on the base of gnathos in male, and by a narrow band forming an incomplete ring near the origin of the ductus seminalis in female. Description. Head: Upper frons orange, lower frons yellowish orange, vertex orange; labial palpus porrect, first segment yellowish orange, second segment distally strongly widened, yellowish orange, slightly darker to orange distally, with small blackish patch dorsoapically, third segment small, yellowish orange. Antenna short, not reaching middle of forewing costa, dark brown, dorsobasally with narrow, longitudinal band of yellowish orange scales. Thorax: Pronotal collar, tegulae, and mesonotum greyish brown mixed with orange; hindlegs unmodified in male. Forewing broad, subtriangular, length 4.9–5.0 mm in male (n = 5) ( Fig. 3 ), 4.9–5.0 mm in female (n = 2) ( Fig. 4 ), termen moderately oblique, costal margin with well developed, small blackish striae; two-toned wing pattern with basal 2/3 with well-defined orange spots and bands on greyish yellow to light brown ground, distal portion with blackish ground color with wide orange sinuous scribbles. Underside greyish brown, with white spots alternating with brown along costa. Hindwing dark brown, paler towards base especially in male, anal margin with row of long, light brown hair tufts. Underside pale brown. Abdomen: Male genitalia ( Fig. 10 ) with tegumen subovate, apically broadly rounded, moderately sclerotized, lateroapically with dense scale sockets on anterior surface, a pair of nipple-shaped projections possibly representing uncus; socii rather large, distally free, membranous, densely bristled lobes; gnathos with two lateral arms, moderately sclerotized bands, extending from middle of tegumen, with distinct group of moderately long spiniform setae at base; vinculum moderately sclerotized; juxta small; caulis moderately long; phallus moderately long, wide at base and slightly narrowing to apex, nearly straight but ventral surface slightly concave, with dense cornuti sockets; valva moderately sclerotized, simple, sinuate; sacculus rather small, projection in a nearly right angle, with dense patch of scale sockets along ventral margin; neck distinct; cucullus elongate-ovate, distally rounded, densely setose, with small, single thorn from below middle of ventral margin. Female genitalia ( Fig 15 ) with papillae anales with dense setae. Tergum VIII smooth except for lateral triangular extensions with dense microtrichia; sternum VII moderately sclerotized, with moderately dense scale sockets, denser along concave, curved posterior margin; ostium bursae behind posterior margin of sternum VII, sterigma a semicircular ridge with two bands of microtrichia extending from each of its end onto lamella postvaginalis; colliculum just below ostium, a moderately wide and sclerotized irregular ring, narrower anteriorly; ductus bursae as long as corpus bursae, widening towards corpus bursa, with sclerotized, narrow band forming an incomplete ring below origin of ductus seminalis; ductus seminalis arising near middle of ductus bursae; corpus bursae large, ovate, signum a depressed, elongate area of scobination near neck of corpus bursae.
