Diagnosis. This new species is similar to P. planidorsalis Gorochov, 1988, but differs from the ectoparameron distinctly wider, and lateral lobe rather long; the lateral part of ectoparameron obviously bent to the dorsal side, and the end hook different in shape.
Description. Male (Fig. 4). Body medium sized, pubescent. Head relatively short, and almost equal to anterior margin of pronotum. Frontal rostrum flat, scapus almost 2.0 times as wide as frontal rostrum. Eyes rather bulging. Lateral ocelli small, granular, medial ocellus longitudinal and not clear. Pronotum distinctly widening posteriorly, disc flattened, with lateral margins angularly rounded into paranota. Tegmina with 3 long and 3 short oblique veins; lateral field with 15–17 subcostal veinlets, apical field is regular; mirror slightly longer than broad (13:11). Hind wings distinctly longer than tegmina. Metanotal gland (Fig.17) slightly wide, the upper half lateral margin short and distinctly swollen, length–width ratio (15:17), an obtuse angle protruding at posterior margin.Anterior tibia swollen at tympana, internal tympanum with a long slit–like opening on posterior side; external tympanum oval and free.
Supra anal plate (Fig. 20) is linked by the diaphragm at the end and covered with short hairs except for the central part, the posterior margin wider round. Subgenital plate distinctly narrowed posteriorly, with circular posterior margin. Phallus (Fig.10–12) relatively strong. Epiphallus rather long, slightly narrow in the middle, and with a pair of serrated protuberance at the end. Ectoparameron obviously wider than epiphallus, with long lateral lobe, the ends ossified hook, lateral margins bend distinctly to the back. Formula slightly ossified, lateral view can see the bone slices.
Coloration. Body greenish when alive. Head with narrow longitudinal yellowish stripes behind eyes. Antennae brownish. Disc of pronotum with a pair of slightly large round black spots on the middle, and lateral edges with yellowish stripes. Tegmen unicolor, with a yellowish stripe along lateral edge of dorsal area. All legs almost yellowish.
Female (Fig. 5). Female approximate male. But the body is slightly stronger than male. Tegmina with 10 longitudinal veins in dorsal part, later field with 13–15 subcostal veinlets.
Measurements (mm). Male: body 18.5–20.5, length with wings 26.5–28.0, pronotum 3.6–4.1, tegmen19.5– 20.5, hind femur 11.5–13.0; Female: body 18.5–21.5, length with wings 27.0–28.0, pronotum 3.7–4.0, tegmen 19.0–21.0, hind femur 14.5–15.5, ovipositor 9.5–10.5.
Remark. Ectoparameron slightly variation respectively from Guangdong and Guangxi material, with almost straight or slightly circular lateral margin in dorsal side.
Distribution. China (Guangdong, Guangxi).
Etymology. This new specific name is derived from the Latin transversus (transverse), a reference to ectoparameron distinctly transverse.
