Description. Imago (Fig. 7). Wingspan 9.5–10.0 mm. Head with vertex pale white, frons grayish brown.
Labial palpus with second segment ochreous brown on outside, ochreous yellow on inside; third segment black except white at base. Antennal scape white; flagellum with basal several flagellomeres white, remaining flagellomeres white ringed with dark brown on dorsal surface, dark brown on ventral surface. Thorax and tegula deep ochreous brown. Forewing ochreous brown; markings white edged with black: a broad fascia extending obliquely from costal 1/4 to before middle of dorsum, a large rounded patch before costal 3/4, extending posteriorly to 2/3 width of wing; cilia along apex white on basal 2/3, ochreous yellow on distal 1/3, along termen to tornus yellowish gray mixed with black. Hindwing and cilia gray. Tibia of midleg with a tuft of long white scales at apex.
Male genitalia (Fig. 19). Uncus oval in basal 3/4, distal 1/4 digitate, rounded at apex. Gnathos very small, rounded apically; lateral arms rather long, longer than uncus, band-shaped. Valva parallel sided dorsoventrally; apex obliquely truncate, with a thin dorsoapical spine and a hairy digitate ventroapical process; costa short, about 1/3 length of sacculus, slightly concave basally. Sacculus narrow. Juxta slender, rounded anteriorly; lateral lobes extremely long, reaching as long as apex of uncus, pointed apically. Saccus broad, almost 1.4 times length of uncus, slightly narrowed to bluntly rounded apex. Aedeagus almost same length as valva, straight, broadened basally and distally, thin medially; cornutus a long spine, placed distally, about 2/5 length of aedeagus.
Female genitalia (Fig. 27). Apophysis anterioris about 3/5 length of apophysis posterioris. 8th sternite almost roundly concave on posterior margin, forming kidney-shaped projection laterally. Lamella postvaginalis heavily sclerotized, irregularly rectangular, concave at middle on posterior margin. Ductus bursae slightly shorter than corpus bursae, with a narrow sclerotized band on ventral surface, membranous on dorsal surface, broadened to a spanner shape anteriorly. Corpus bursae elongate, with a sclerotized plate at base bearing several thorn-like spines, shrunken lateromedially, anterior 2/5 rounded; two large, toothed, crescent-shaped signa sometimes overlapping with each other.
Diagnosis. This species is most similar to the new species P. clavata sp. nov. in the male genitalia, but differs from it in having a very small gnathos, the valva with a longer spinous dorsoapical process, and the cornutus about 2/5 length of the aedeagus.
Etymology. The name is derived from the Latin lunularis (= crescent-shaped), referring to the shape of the signum.
