Diagnosis. The new species can be distinguished in the male genitalia by the transtilla extended ventrad triangularly, the valva with a setose pad at base on the ventral margin, and the aedeagus with a short preapical spine; in the female genitalia by the ductus bursae with dense tiny denticles at posterior 3/5.

Description. Adult ( Fig. 13 View FIGURES 10−15 ). Forewing length 5.0– 6.5 mm.

Head yellow. Labial palpus yellow, with scattered greyish-brown scales on outer surface of first and second palpomeres, denser at apex of second palpomere; third palpomere 2/3 length of second palpomere. Antenna yellow on ventral surface; scape greyish brown, flagellum yellow annulated with greyish brown on dorsal surface.

Thorax and tegula greyish brown, mixed with yellow. Forewing ground color yellow, covered with greyishbrown scales, denser basally and distally; discal and discocellular dots greyish brown, discocellular dot banded; plical dot greyish brown, beyond middle of fold; black dots extending from middle of costal margin to before apex, evenly spaced; terminal dots black, smaller; fringe yellow. Hindwing grey; fringe greyish brown. Legs yellowish white; on ventral surface, femur of foreleg greyish brown, tibia greyish brown mixed with yellowish white, femur of midleg greyish brown apically, tibia greyish brown except yellowish white at middle and at apex respectively, tarsi of fore- and midlegs greyish brown except yellow at base of basal tarsomere as well as at apices of basal two and apical one tarsomeres, tibia of hindleg with scattered greyish-brown scales.

Male genitalia ( Fig. 25 View FIGURES 22−27 ). Uncus elongate, sub-parallel to before narrowly rounded apex. Tegumen narrowed medially; lateral arm uniform, obtuse at apex. Valva sub-parallel in basal half, slightly wider and sub-parallel from middle to before obtuse apex, setose in distal half, with an ovate setose pad at base on ventral margin; costa narrowly banded, basal half uniform, distal half narrowed to before tip of costal margin; transtilla narrowed toward middle, extending ventrad triangularly, dentate laterally. Sacculus sub-quadrate, apex shallowly concave below middle, produced to a sub-triangular process dorsoapically; dorsal margin heavily sclerotized; ventral margin folded, forming a wide band. Saccus shorter than uncus, wide at base, narrowed to rounded apex. Juxta U-shaped. Aedeagus as long as valva, inflated medially, with a small spine at pre-apex, with short spines beyond basal 2/3; cornutus absent.

Female genitalia ( Fig. 35 View FIGURES 32−35 ). Papilla analis quadrate, setose on dorsal surface. Apophyses posteriores twice as long as apophyses anteriores. Eighth tergite sub-trapezoidal, straight on anterior and posterior margins. Eighth sternal plate spiculate, arched and lined with long setae on posterior margin. Lamella antevaginalis concave in broad U-shape medially on posterior margin, trapezoidally produced posterolaterally, widely concave medially on anterior margin, with a sub-ovate plate anterolaterally. Ductus bursae weakly sclerotized from posterior 1/5 to 3/5, with dense tiny denticles at posterior 3/5; ductus seminalis arising from posterior 3/5 of ductus bursae. Corpus bursae ovate; signum small, with an apical spine.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the Latin pro- and spina, referring to the aedeagus with a spine at pre-apex.
