Type material. CHINA, Yunnan: Holotype ♂, Pukawang Village (27.84°N, 98.32°E), Dulongjiang Town, Gongshan County , Nujiang , 1335 m, 8.VI.2017, leg. KJ Teng et al., slide No. ZXJ19369 . Paratypes: 12♂, 6‒12.VI.2017, other same data as holotype ; 4♂, 28‒30.V.2017, other same data as holotype, slide Nos. ZXJ20044, ZXJ20045, ZXJ20046 .

Diagnosis. The new species can be distinguished from its congeners by the valva with a bilobed process at basal 1/3 and a rounded setose process at middle on the ventral margin, and the sacculus with a hooked process.

Description. Adult ( Fig. 9 ). Forewing length 6.5–7.5 mm.

Head pale yellow. Labial palpus pale yellow; first and second palpomeres with scattered black scales on outer surface, second palpomere with a black ring at apex; third palpomere with a black line from base to before apex on ventral surface. Antenna with scape yellow mixed with blackish brown; flagellum blackish brown, alternated with yellow on ventral surface.

Thorax and tegula dark brown. Forewing greyish brown; costal margin with black dot at middle and at distal 1/3, between two spots suffused dense black scales, with yellow spot before middle and distal 1/4; discal, discocellular and plical dots black, plical dot smaller, at distal 2/5 of fold, discal dot at middle of cell, discocellular spot at outer margin of cell, banded; fringe yellowish brown, tipped with black and blackish grey around tornus. Hindwing and fringe deep grey. Legs yellowish white; on ventral surface, coxa and femur of foreleg with blackish-brown scales, tibia blackish brown except yellowish white apically, tarsus blackish brown except yellowish white at base of basal tarsomere and at apices of basal two tarsomeres, femur of midleg blackish brown except yellowish white at middle and at apex respectively, tarsus blackish brown except yellowish white at base of basal tarsomere and at apices of basal two tarsomeres, yellow at apical one tarsomere, tibia of hindleg blackish grey, tarsus with basal four tarsomeres blackish grey except yellowish white at apices.

Male genitalia ( Fig. 21 ). Uncus wide at base, narrowed to middle, distal half uniformly narrow to before pointed apex. Tegumen narrowed medially; lateral arm narrowed anteriorly, obtuse at apex. Valva with basal half sub-parallel, distal half narrowed toward rounded apex, setose ventrodistally; ventral margin with a large bilobed process at basal 1/3, which has dense stout setae on its ventral margin, with a large roundly produced setose process at middle; costa banded, narrowed to tip of costal margin; transtilla slender, narrowed toward middle, pointed at apex. Sacculus sub-quadrate; apex folded toward base, with a hooked process. Saccus as long as uncus, wide at base, narrowed to rounded apex. Juxta V-shaped; lateral arm slightly notched apically. Aedeagus slightly longer than valva, slender in basal 1/3, tubular from basal 1/3 to before apex, with horn-shaped distal process bent from preapex toward base in broad U-shape; cornutus absent.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the Latin bi - and processus, referring to the two differently shaped processes on the ventral margin of valva.
