Dichomeris pueriensis Li, sp. nov.

(Figs 12, 30)

Type material. Holotype ♂, CHINA, Yunnan: Taiyanghe Nature Reserve [Pu'er City], 1450 m, 4.VIII.2014, leg. ZG Zhang, gen. slide No. LX 24449.

Paratypes (4♂). Yunnan: 1♂, same data as holotype, gen. slide No. LX 24448; 1♂, 23.VIII.2014, other data same as holotype, gen. slide No. LX 25261; 2♂, 2.IX.2014, other data same as holotype, gen. slide No. LX 24439.

Diagnosis. The new species is similar to D. similisexafurca sp. nov. and D. sexafurca Li & Zheng, 1996 in the male genitalia in having similar sicae. It can be separated from the latter two species by the apex of the forewing distinctly produced, which is slightly produced in the latter two species. The male genitalia are distinguished by the lateral arms of the vinculum with three processes, the left lobe of the sica with two spines on the outer margin, and the two lateral sclerotized lobes of the aedeagus unequal in length and the longer lobe with a small process on the inner side. In D. similisexafurca sp. nov., the lateral arms of the vinculum have two asymmetrical processes, the left lobe of the sica is serrate on the outer margin, and the lateral sclerotized lobes of the aedeagus are equal in length. In D. sexafurca, the lateral arms of the vinculum have two symmetrical processes, the left lobe of the sica is smooth on the outer margin, and the lateral sclerotized lobes of the aedeagus are unequal in length and the longer lobe is serrate on the inner side.

Description. Adult (Fig. 12). Wingspan 14.5–16.0 mm.

Head. Vertex grey, yellow laterally; frons yellow, dark brown laterally. Labial palpus dark brown on outer surface, pale yellow on inner surface; second segment about twice length of eye diameter, longer than third segment, without distinct scale tuft. Antenna with scape dark brown on dorsal surface, greyish brown on ventral surface; flagellum yellow, annulated with brown on dorsal surface.

Thorax. Mesonotum and tegula greyish brown; mesothoracic anepisternum with yellowish-brown hair pencils in male. Forewing subparallel from near base to before triangularly produced apex, termen obliquely straight; ground color dark brown, yellow along basal half of Sc vein, and along distal half of cell and fold; fringe deep yellowish brown in basal 2/3, greyish brown in distal 1/3. Hindwing and fringe dark brown. Fore- and midlegs dark brown on outer surface, yellowish white on inner surface; hindleg with femur pale brown, tibia and tarsus yellowish brown, tarsomeres pale brown apically on outer surface.

Abdomen. Male genitalia (Fig. 30). Uncus narrowed near base, parallel from near base to obtusely rounded apex. Gnathos longer than uncus, curved medially; culcitula subtriangular. Valva shorter than tegumen plus uncus, parallel from base to 2/3, convex at basal 3/4 on costal margin, obtusely rounded at apex; valvella digitate, approx. 1/4 length of valva, rounded apically. Setose patch digitated, approx. 1/2 length of valvella, with dense short setae. Vinculum with height slightly shorter than tegumen plus uncus; lateral arm slightly arched outward in posterior 3/4; with three lateral processes: a pair of spiniform lobes arising from above middle of lateral arm, apically extending to posterior end of lateral arm, with sparse setae, a single hooked lobe arising from anterior 2/5 of left lateral arm. Saccal region wide, straight on anterior margin; sica asymmetrical, approx. 2/5 length of lateral arm, separated from basal 1/3, U-shaped distally; left lobe with a large spine-shaped process and a small spine-shaped process on outer margin, right lobe with numerous denticles on outer margin. Aedeagus tapered from base to apex, with two lateral sclerotized lobes: left lobe horn-shaped, approx. 1/5 length of aedeagus, with a small process above middle on inner side; right lobe short, spiniform, approx. 1/2 length of left one.

Female unknown.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the type locality, Pu'er City, Yunnan Province.
