Diagnosis. The new species can be distinguished from other species of the group by the sub-quadrate uncus, the horizontally widened mesial plate of the gnathos, and the valva having three apical processes and one small trapezoidal lobe.
Description. Adult ( Fig. 14 View FIGURES 9‒16 ). Forewing length 4.5‒5.5 mm.
Head: Vertex shiny white, frons greyish brown, occiput dark ocherous brown. Labial palpus with basal and second palpomeres dark ocherous brown on outer surface, pale orange yellow on inner surface; third palpomere black except white at apex.Antenna with scape white on dorsal surface, greyish brown on ventral surface; flagellum black, annulated with white dorsally.
Thorax: Dorsum of mesothorax and tegula rust brown. Forewing orange yellow, mixed with grey and black scales between fold and dorsum; markings white edged with black scales: costal spot sub-triangular, from about basal 2/3 obliquely outward to middle of outer margin of cell; basal streak extending obliquely inward to base of fold; antemedian streak from dorsal 2/5 oblique inward to anterior margin of cell, subparallel with basal streak; dorsal streak from distal 1/4 oblique outward to posterior margin of cell, then curved outward to before posterior angle of cell; tornal spot represented by diffused blackish grey scales beyond dorsal streak; apical and terminal spots separated, apical spot larger; fringe orange yellow except grey along distal part of dorsum. Hindwing and fringe greyish brown. Fore- and midlegs with dorsal surface white, ventral surface black, tibiae with white scale tufts at apex, tarsi with wide white distal band at basal two tarsomeres respectively, apical tarsomere of midleg white; hindleg brown ventrally, greyish brown dorsally, tarsus with basal tarsomere white apically, rest tarsomeres white, with two black bands on second and third tarsomeres basally.
Abdomen: Male genitalia ( Fig. 36 View FIGURES 35‒39 ). Uncus sub-quadrate, widened and obtuse apically, slightly produced outward posterolaterally. Gnathos as long as uncus; mesial plate horizontally widened, produced outward anterolaterally; basal arms wide, longer than mesial plate. Valva sub-rectangular, bilobed apically: dorsal lobe very short, digitate, with small denticles and tufted long setae distally, with fine spines along ventral margin, ventral lobe very long, wide at base, slightly narrowed to furcate apex, with fine spines along dorsal margin; costa with a large process widely apart basally, flagellate distally, curved at basal 1/3 almost by a right angle, then extending outward, with a small trapezoidal process at base on outer margin. Sacculus wide at base, lightly narrowed to base of ventroapical process. Saccus long, clavate, longer than valva excluding length of distal process. Juxta sub-rectangular, with digitate processes basolaterally; basal lobe slender, clavate, slightly longer than uncus. Aedeagus slender, slightly longer than valva; cornutus absent.
Female genitalia ( Fig. 51 View FIGURES 51‒55 ). Apophyses anteriores about 2 times length of apophyses posteriores. Eighth segment rectangular, eighth sternum with a shallow longitudinal narrow groove medially. Antrum narrow, as long as ductus bursae. Ductus bursae membranous, uniformly broad. Corpus bursae ovate; signum a narrow band, with a line of small dentitions and ill-defined basal plate.
Distribution. China (Yunnan).
Etymology. The epithet of the new species is derived from the Latin quadri- and processus, referring to the four processes of the valva in the male genitalia.
