Etymology.

The specific epithet refers to the pygofer without medioventral process.

Measurements.

Body length (from apex of vertex to tip of tegmina): male 5.2-5.7 mm (n = 6); female 6.3-6.8 mm (n = 10); tegmen length: male 4.4-4.9 mm (n = 6); female 5.3-5.9 mm (n = 10).

Diagnosis.

The salient features of the new species include the following: tegmina milky-hyaline, veins with black hair-bearing granules, many dark markings on veins (Figs 13, 18); pygofer with medioventral margin V-like (Fig. 19); aedeagus with phallus slender, acute at apex (Fig. 21).

Description.

Coloration. General color milky white to yellowish brown (Figs 13-18). Vertex yellowish green, submedian carinae brown. Frons yellow at basal half and milky white at apical half. Genae white. Postclypeus yellow at basal half and white at apical half. Anteclypeus milky white. Rostrum black brown at apex. Antennae yellowish brown. Eyes and ocelli reddish brown. Pronotum yellowish green, lateral margin milky white, with dark brown markings at apex of lateral carinae. Mesonotum yellowish green, with dark brown markings at near apex of lateral carinae and apex of scutellum. Tegmina milky white, hyaline, veins white with short dark brown stripes. Wings hyaline. Legs with longitudinal stripes, dark brown.

Head and thorax. Vertex (Figs 13, 15) quadrate, wider at base than length about 1.17: 1, width at apex narrower than at base (0.4: 1), anterior margin sinuate, carinae distinct, submedian carinae uniting at apex. Frons (Figs 16, 17) longer at midline than wide at widest part, about 1.19: 1, widest at apex, carinae distinct. Postclypeus as wide at base as frons at apex, median carina distinct. Antennae with first segment rectangular, with central ridge, longer in middle line than widest part about 3.67: 1, longer than the second about 1.48: 1. Pronotum (Figs 13, 15) shorter than vertex (0.72: 1). Mesonotum longer in middle line than vertex and pronotum together, about 1.57: 1, median carina reaching the end of scutellum, lateral carinae not attaining hind margin. Tegmen (Fig. 18) longer than widest portion about 3.7: 1. Spinal formula of hind leg 5-6-4.

Male genitalia. Anal segment (Figs 19, 20) at widest part narrower than pygofer, large, broad, flattened dorsoventrally and apex rounded. Anal style moderately long. Pygofer (Figs 19, 20) slightly compressed laterally, in posterior view with opening longer than wide, medioventral margin V-like. Aedeagus (Fig. 21) with phallus slender, long, with base broad, then become of slender gradually, acute at apex. Phallobasal forked at apex, in profile broad, apex with two finger-like processes and near base with a stout tooth-like process. Genital styles (Fig. 22) large, broad at base, tapering apically.

Plant associations.

Bamboo.

Distribution.

Southwest China (Yunnan).

Remarks.

This species is similar to P. theognis Fennah, 1978 but differs from it by: (1) tegmina (Fig. 18) with transverse veins milky white, without brown stripe border (tegmina with transverse veins bordered with brown stripe in P. theognis ); (2) pygofer of male (Fig. 19) without medioventral process (pygofer with medioventral process in P. theognis ); (3) genital styles (Fig. 22) with base broad, not twisted apically (genital styles slender, with apical quarter twisted in P. theognis ).

This species is also similar to P. maculata Muir, 1916 but differs from it by: (1) pygofer of male (Fig. 19) with medioventral margin V-like (pygofer with medioventral margin broadly U-shaped in P. maculata ); (2) anal segment of male (Fig. 19) with length longer than width, exceeding 1.6: 1 (anal segment with length longer than width about 1.1: 1 in P. maculata ); (3) aedeagus (Fig. 21) with phallus slender, acute at apex (aedeagus with phallus with apex rounded in P. maculata ).
