( Fig. 29 )

Holotype worker: CHINA: Guangxi: Guilin City, Longsheng County, Huaping Village , 949 m, 25.6039° N, 109.0975°E, 11.VIII.2019, Chunxuan Luo leg., No. GXNU192346 [ GXNU] ; Paratypes: same data as holotype [1 worker, GXNU; 1 worker, SWFU] .

Other material examined. CHINA: Zhejiang: Qiangdaohu , 29.IV.2018, Yuhao Zhao leg., GXNU186721 [2 workers, GXNU] .

Diagnosis. Concolorous species, whole body yellow. Head in full-face view distinct longer than broad (CI 74–77), with straight posterior margin, rounded posterolateral corners; maximum diameter of eyes distinct broader than the width of apical funiculus. Subpetiolar process cuneiform, anteroventral corner angular and posteroventral corner broadly rounded. Body smooth and shiny, except sparsely shallow piligerous punctures.

Holotype worker. HL 0.68, HW 0.52, CI 76, SL 0.32, SI 61.54, ED 0.15, MSL 0.90, PW 0.40, PL 0.36, PH 0.40, DPW 0.36, LPI 111.11, DPI 100, TL 3.36.

Paratype workers. HL 0–0.65–0.68, HW 0.49–0.52, CI 74–77, SL 0.32–0.37, SI 61–74, ED 0.14–0.15, MSL 0.86–0.90, PW 0.35–0.40, PL 0.34–0.36, PH 0.36–0.40, DPW 0.34–0.36, LPI 108–113, DPI 100–102 TL 2.90–3.36 (n=2).

Head. In full-face view subrectangular, distinctly longer than broad (CI 74–77), lateral margins convergent anteriorly, and posterior margin straight, posterolateral corners rounded. Anteromedial portion of clypeus concave, lateral portion of clypeus forming angular lobe. Frontal carina short, separate and nearly parallel. Antennae with 11 segments. Eyes large, maximum diameter distinct broader than the width of apical funiculus, ommatidia with a clear edge. Mesosoma. In lateral view dorsal outline of mesosoma feebly convex, pronotmespleural suture obscure, posterodorsal corner obtuse-angulate, posterior edge of propodeum carinate, declivity of propodeum straight. In dorsal view, propodeum slightly broader than pronotum and mesonotum. Metasoma. Petiole in lateral view, appears rounded, with steep anterior margin and convex posterior margin, dorsum strong convex; subpetiolar process cuneiform, anteroventral tooth sharp and posteroventral corner broadly rounded. In dorsal view, petiole lateral margins convex, anterior margin straight and carinate, anterolateral corner angular and posterodorsal corner rounded. Abdominal segment III in lateral view first gastral segment rounded, higher than long; in dorsal view abdominal segment III subtrapezoidal, broader posteriorly, broader than long; lateral margins convex. Sculpture. Body smooth and shiny, except sparsely shallow piligerous punctures. Pilosity. Body entirely and densely covered with suberect long hairs. Color. Body yellow.

Notes. This species is verily similar to P. muiri , but can be separated from the latter by a combination of the following characteristics: body light yellow; in lateral view, dorsal outline of mesosoma slightly convex; in dorsal view, first gastral segment broader posteriorly.

Distribution. China (Zhejiang, Guangxi).

Etymology. The new species is named after an excellent katydids taxonomist, Fuming Shi (Hebei University, China), who is the doctoral supervisor of the first author.
