Figs 1E , 2C , 3E

Diagnosis

The new species can be distinguished from its congeners by the smaller size (9.5‒10.0 mm), and the distally narrowed forewing with costal margin concave beyond middle.

Etymology

The specific epithet is derived from the Latin minisculus, referring to the small size of the adult.

Description

ADULT ( Figs 1E , 2C ). Wingspan 9.5‒10.0 mm. Head and antenna orange white. Labial palpus orange white except dark brown on outer surface of second palpomere. Thorax orange white; tegula dark brown. Forewing narrowed distally, costal margin gently concave beyond middle, apex roundly produced, termen shallowly concave; ground colour dark brown except pale orange from basal 2/5 to apex along costal margin, mixed with orange-white scales in distal 3/5; dorsum with an orangewhite spot at base; antemedian fascia orange white, from basal 2/5 of costal margin oblique outward to before middle of dorsum; discocellular stigma small, rounded, black; costal spot orange white, at distal 1/5; dorsal spot smaller, orange white, at distal 1/5; fringe greyish brown, basal band orange white; M 1 stalked with R 3+4+5, M 2+3 and CuA 1+2 almost arising from same point, CuA 1 and CuA 2 stalked for about half length of CuA 2. Hindwing and fringe pale greyish brown; fringe with orangewhite basal line and weak median line. Legs pale yellow except fore and mid femora and fore tibia dark brown ventrally.

MALE GENITALIA ( Fig. 3E ). Uncus wide at base, narrowed to middle, distal half clubbed. Gnathos with median process elongate, broad basally, uniform medially, distal ¼ slender, hooked, pointed at apex. Valva slightly extending dorsad distally, wide at base, narrowed to beyond middle, thereafter slightly narrowed to rounded apex; costa shallowly concave; sacculus broad basally, narrowed distally, straight ventrally, reaching 1/5 length of valva. Vinculum narrow, obtuse on anterior margin. Juxta shieldshaped, concave in broad V shape on posterior margin, rounded on anterior margin; posterolateral lobe subquadrate, straight at apex. Aedeagus slightly shorter than valva, wide at base, slightly narrowed to apex, curved ventrad at basal ¼, with dense granules in vesica; cornuti consisting of cluster of spinules at basal ¼ and cluster of spines distally.

FEMALE. Unknown.
