Adult (Fig. 25). Wingspan 15.0−22.0 mm. Head white, with scattered ochreous brown scales. Labial palpus with first palpomere black, second and third palpomeres white; second palpomere black in basal 1/4, ringed with black beyond middle, with loose long scale tuft on ventral surface; third palpomerewith black ring near base, at middle and at 2/3 respectively, black at apex, about same length as first and second palpomeres together. Antenna with scape grayish white, mottled blackish brown scales on dorsal surface; flagellum grayish white, with dark brown annulations. Thorax and tegula white, with ochreous brown scales. Forewing ground color white, sprinkled with ochreous brown and black scales, with dense ochreous brown scales along posterior margin; distal half of costal margin with five short blackish brown streaks alternated with white extending obliquely outward; terminal band widening along posterior half of termen; ochreous brown dot at 1/6 and 1/4 below costal margin respectively; sub-elliptical ochreous brown spot placed at anterior 1/3 near base; broad ochreous brown fascia from between before 1/3 and middle of costal margin reaching approximately posterior 1/5, oblique inward, longitudinally with black scales at its anterior 1/4, 1/2 and 3/4; discocellular spot rhombic, ochreous brown, edged with black scales anteriorly; subterminal spot round, ochreous brown, anteriorly meeting terminal band, longitudinally with black scales along middle line; dorsum with ochreous brown spot near base, with ochreous brown stripe from 1/5 extending obliquely outward across fold to about 2/5 of cell, widened anteriorly; tornal spot smaller than subterminal spot, joined with terminal band posteriorly; cilia dark gray, with a row of short blackish brown scales at base, except white above and beneath apex. Hindwing and cilia from gray to dark gray. Forelegs with coxae and femora dark brown on ventral surface, grayish white on dorsal surface, tibiae blackish brown on outer surface, white on inner surface, tarsi black ringed with white; midlegs white, femora with scattered dark brown scales on ventral surface, tibiae black at middle on outer surface and with black broad rings near apex, tarsi black with white rings; hindlegs grayish white, tibiae with scattered brown scales on outer surface and covered with dense long pale yellowish white hairs dorsally, tarsi brown ringed with white distally.
Male genitalia (Fig. 39). Uncus gradually widened toward almost straight apex, with dense long setae on ventral surface. Gnathos curved beyond middle, distal 2/5 heavily sclerotized, pointed apically. Tegumen slightly convex at middle on anterior margin. Valva with basal 3/5 narrow, distal 2/5 elliptically expanded and covered with dense long hairs. Valvella about 1/4 length of valva, crescent-shaped, curved outward, with dense long setae on outer surface. Juxta sub-trapezoidal, roundly protruded and with long setae posterolaterally. Saccus longer than valvella, tapered to bluntly rounded apex. Aedeagus curved in S shape, dilated spherically in basal 2/5, slender in distal 3/5, bluntly rounded apically.
Female genitalia (Fig. 52). Papillae anales with dense setae. Anterior apophyses about 1/4 length of posterior apophyses. Eighth segment gradually widened anteriorly; eighth tergite slightly convex and sclerotized on posterior margin; lateral band widened anteriorly, joined at anterior 2/5, truncate at anterior end. Ostium bursae elliptical. Ductus bursae slightly coiled, about half length of corpus bursae, sclerotized at base. Ductus seminalis arising from posterior end of corpus bursae. Corpus bursae somewhat elongate elliptical; signum transversely subelliptical, placed at posterior 2/5, with transverse carina.
Diagnosis. Encolapta lunata sp. nov. can be separated from its congeners by the crescent-shaped valvella in the male genitalia, and the apically truncate lateral band in the female genitalia. It is superficially similar to E. bifasciaria sp. nov., and the differences between them are stated under the latter species.
Distribution. China (Hainan, Yunnan).
Etymology. The specific name is derived from the Latin lunatus, meaning crescent-shaped, referring to the shape of the valvella.
