Dicerapanorpa harmonia sp. nov.

( Figs 1–6 )

Type material. Hඈඅඈඍඒඉൾ: CHINA: Yඎඇඇൺඇ: ♁ ( DALU: CN- 21Di00059), Diqing Tibetan Autonomous Prefecture, Weixi County, northern hillside in an alpine ravine, 27°20′58.92″N, 99°18′12.23″E, 2940 m, 17.vii.2021, leg. Ji-Shen Wang. Pൺඋൺඍඒඉൾ: 1 ♀ ( DALU: CN- 21Di00058), same data except 16.vii.2021.

Diagnosis. The new species superficially resembles D. zhongdianensis , but can be differentiated from the latter by the following characters: 1) male paramere with ventral branch longer than half length of middle branch ( Fig. 3 ) (vs. shorter), and 2) female medigynium with main plate narrower towards base ( Fig. 6 ) (vs. with parallel lateral margins).

Description. Measurements (mm). Male (holotype): AtL 11.3, AbL 10.8, BL 14.8, FL 14.1, FW 3.3, HL 12.8, HW 3.2. Female (paratype): AtL 11.5, AbL 7.4, BL 12.3, FL 14.9, FW 3.7, HL 13.0, HW 3.6.

Male. Head ( Fig. 1 ). Vertex yellow, with large black spot on each side, and three smaller, blurred spots encircling each large one. Ocellar triangle black. Rostrum yellow, with two black frontal stripes.

Thorax ( Fig. 1 ). Pronotum with five black thick setae along each side of anterior margin. Meso- and metanotum black laterally, with yellow median stripe.

Wings ( Fig. 1 ). Membrane colorless and hyaline, with greatly reduced, spot-like pterostigmal band. Pterostigma light yellowish brown.

Abdomen ( Fig. 1 ). T2–T5 black laterally, with broad yellow median stripe. A6 yellowish brown with pair of divergent anal horns on dorsal apex. A7 and A8 greatly constricted at base, yellowish brown with irregular black textures.

Male genitalia ( Figs 3, 4 ). Genital bulb oval. Epandrium (T9) broad, deeply emarginated terminally and forming pair of finger-like processes laterally. Hypandrium (S9) split into pair of long, stripe-like hypovalves. Hypovalve with row of long stout bristles along inner margin. Gonostylus shorter than gonocoxites, with well-developed basal lobe and subtriangular middle tooth. Paramere trifurcate: ventral branch long and straight; median branch longest and straight; dorsal branch slightly longer than half length of middle branch and slightly curved. Ventral valves of aedeagus membranous with rounded apex.

Female. Habitus ( Fig. 2 ) similar to males. Subgenital plate ( Fig. 5 ) broad, with apex greatly narrowed and subtriangular, bearing long stout setae marginally. Medigynium ( Fig. 6 ) with main plate narrower towards base, and pair of earlobe-like processes on lateral margin.

Etymology. The new species is named after Harmonia, the immortal goddess of harmony and concord in the Greek mythology, to commemorate a harmonious and high- -yielding expedition in northwestern Yunnan (July, 2021) conducted by the author and his companions (Drs Hao Xu, Lu Qiu, and Mr. Guo-Cong Huang). Noun in apposition.

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