Type material. Holotype ♂: CHINA, Yunnan, Longchuan, Huguo, 9.VIII.2013, leg. Yanju Dong. Paratype: 1♂: same data as the holotype.
Diagnosis. This new species is similar to P. acutiparamerus Liu & Shi, but is distinguished by the thin lateral lobes of the epiphallus which are bent outwards and the epiphallus parameres distinctly bent inwards at apex. In P. acutiparamerus, the lateral lobes of epiphallus are rather wide and straight, and the epiphallus parameres only slightly bend inwards at apex.
Description. Male: Body small and slender (Fig. 3). Head rather short, frontal rostrum as wide as scapus; median ocellus small and transverse oval, lateral ocellus nearly round, eyes rather oval and distinctly projecting; apical joint of maxillary palpus widened and sloped at apex, rather longer than third joint; apical joint of labial palpus widened, longer than second joint. Pronotum obviously wider than long; anterior margin slightly straight, posterior margin sinuate and protruding on midway; lateral lobes longer as same as high, anterior lower angles round, posterior lower angles nearly round, lower margin obviously round. Tegmina extending over apex of abdomen, dorsal area with four longitudinal veins; hind wings distinctly longer than tegmina, reaching apex of hind tibia. Fore tibia with a large and oblong internal tympanum, nearly half the length of the tibia, without external tympanum. Hind tibia with three long spines along either margin of dorsal side of apical part, and some very small spines on basal part, of which 2-3 are placed along the outer margin and 1–2 along the inner margin. Abdominal tergite I with a pair of swellings, II with a swelling in center and inclined forwards.
Supra-anal plate (Fig. 11) wider than long, mid-posterior membranous; dorsal area with two short setae area in centre; posterior margin nearly straight. Subgenital plate rather long, with posterior margin narrowly rounded and nearly straight. Genitalia (Figs. 8–10): epiphallus rather short; medial lobes of epiphallus long, thin with acute teeth; lateral lobes of epiphallus thin, long and sac-like covered with short spines, clearly bent outwards; epiphallus parameres long and acute at apex; ectophallus parameres rather short and bent outwards, acute at apex.
Female. Unknown.
Coloration. Body dark brown. Tegmina light brown with some irregular black spot; lateral field brown. All femora dark brown, tibia light brown.
Measurements (mm). Male: body 8.2–8.5, length with wings 14.2–14.6, pronotum 1.1–1.2, tegmen 9.5–9.6, hind femur 5.5–5.8.
Distribution. China (Yunnan).
Etymology. The specific name is derived from Latin soror (sisters), referring to this species similarity to P. acutiparamerus Liu & Shi.
