Diagnosis. The new species is superficially similar to Dicerapanorpa triclada , but can be differentiated from the latter by the following characters: in males, 1) T2–T5 black with distinct yellow median stripe ( Fig. 13 ) (vs. lacking) and A6–A9 yellowish brown ( Fig. 13 ) (vs. mostly black); 2) ventral valves of aedeagus short ( Fig. 16 ) (vs. strongly protruded); and in females, 3) medigynium broadening from base towards apex ( Fig. 18 ) (vs. nearly parallel marginally in distal half).

Description. Measurements (mm). Male (holotype): AtL 12.5, AbL 13.3, BL 18.0, FL 14.2, FW 3.3, HL 13.0, HW 3.2. Male (paratypes): AtL 12.3–12.5, AbL 13.2–13.3, BL 18.0–18.2, FL 14.0–14.2, FW 3.2–3.3, HL 13.0–13.1, HW 3.1–3.2. Female (paratypes): AtL 13.0–13.2, AbL 10.0–12.5, BL 14.0–16.8, FL 14.2–14.6, FW 4.0–4.2, HL 13.0–13.3, HW 3.8–4.0.

Male. Head ( Fig. 13 ). Vertex yellow, with large black spot on each side, and three smaller, blurred spots encircling each large one. Rostrum yellow, with two black frontal stripes.

Thorax ( Fig. 13 ). Pronotum with six black thick setae along each side of anterior margin. Meso- and metanotum black laterally, with yellow median stripe.

Wings ( Fig. 13 ). Membrane colorless and hyaline. Pterostigmal band presented as a small spot. Pterostigma light yellowish brown.

Abdomen ( Fig. 13 ). T2–T5 black laterally, with narrow yellow median stripe. A6 yellowish brown with pair of divergent anal horns on dorsal apex. A7 and A8 yellowish brown, greatly constricted at base.

Genitalia ( Figs 15, 16 ). Genital bulb broad oval, yellowish brown. Epandrium broad, deeply emarginated terminally and forming pair of finger-like, divergent processes laterally. Hypandrium split into pair of hypovalves. Hypovalve dark brown with row of long stout bristles along inner margin. Gonostylus shorter than gonocoxites, with well-developed basal lobe and subtriangular middle tooth; basal lobe with greatly curved, hook-like apex. Paramere trifurcate: ventral branch elongated; median branch slightly longer than ventral branch; dorsal branch slightly longer than twice length of ventral branch. Ventral valves short with rounded apex.

Female. Habitus ( Fig. 14 ) similar to males. Subgenital plate ( Fig. 17 ) subtrapezoidal with apex greatly narrowed, and bearing long stout setae marginally. Medigynium ( Fig. 18 ) with main plate slightly broadening from base towards apex; earlobe-like process in middle of each side of main plate; posterior arms shorter than 1/3 of main plate.

Etymology. The new species is named after the Nakhi People, a Chinese ethnic group inhabiting the foothills of the Yulong Snow Mountain. Noun in apposition.

Distribution. China: Yunnan (Lijiang) ( Fig. 54 ).
