Type material. Holotype, 1♂, CHINA: Yunnan Province, Mohan. 101.7025°E 21.2452°N, H, 950m, 13.V.2015, (light-trap), collected by Wu Yunfei. Paratype, 1♂, CHINA: Yunnan Province, Lianghe, 98.2068°E 24.7807°N, H, 980 m. 4.Ⅹ.2015, (light-trap), collected by Zhan Hongping.

Description. Length: male 3.3–3.5 mm.

Body (Fig. 1A, B) orange with mottled spots. Eyes (Fig. 1D) gray. Crown (Fig. 1C,F) rounded and protruding. Coronal suture short, mid length shorter than interocular width, width of the crown narrower than that of the pronotum. The base color of the crown is yellow, with red stripes in middle area. Anterior margin slightly red, and white arcuate spot on both sides of the tip. Face (Fig. 1E) yellowish–white and slightly raised, with multiple parallel horizontal stripes on the frontoclypeus area, anteclypeus white. Pronotum (Fig. 1C) dirty yellow, anterior margin arcuate with irregular yellow spots, posterior margin straight. Scutellum (Fig. 1C) yellow, darker at lateral corners, two brown spots above transverse indentation, brown longitudinal stripe extends to apical corner.

Forewing (Fig. 1A, B, G) orange and bearing irregular brown spots, brochosome area reddish–yellow, apical area becoming lighter and translucent. Hindwing (Fig. 1H) transparent, and anal veins and CuA veins forked.

Abdominal apodemes (Fig. 1I) only reaching the 4th abdominal sternite. Pygofer (Fig. 1J, K) broad, pygofer appendage slightly protruding on dorsal margin, a macroseta at the base of pygofer appendage, and a row of short peg-like setae along ventral margin.

Subgenital plate (Fig. 1J,K) fused at base, petal-shaped, the length exceeding pygofer, several densely-grouped macrosetae emerging in middle area, and some microsetae scattered apically. Style (Fig. 1M) long, with a broad basal section and a curved and slender neck. Connective (Fig. 1M) fused to the aedeagus, triangular shaped with prominent central process. Aedeagus (Fig. 1M) shorter than style, shaft tubular and curved dorsally, with short star-shaped process on anterior margin, posterior margin serrated at top of shaft. Gonopore apical.

Etymology. The specific epithet is the Latin noun stella, referring to the star-shaped aedeagal process.

Remarks. This species has an aedeagus very similar in form to that of P. arooni, but it differs from that species in having a star-shaped apical processes and a finely serrated shaft ( P. arooni has the shaft bearing numerous thornlike extensions).
