Type material.-

Holotype ♀, 1300-1400m, Fenshuiling, Jinping, Yunnan, China, 4.IX.2016, George Ho Wai-Chun (HKES); Paratype 1♀, 1300-1400m, Fenshuiling, Jinping, Yunnan, China, 4.IX.2016, George Ho Wai-Chun (HKES).

Diagnosis.-

Paragongylopus (Planoparagongylopus) lii sp. n. is similar to Paragongylopus (Planoparagongylopus) nabanheensis sp. n., but can be easily distinguished by granulated body, nearly square mesonotum, rectangular metanotum and indistinct elevations on legs.

Description.-

Female (Figs 7-8, 22-23): Small size. Body flattened and stout. General color of body and legs brown. Head rounded in dorsal view, dorsoventrally flattened. Vertex flat and unarmed. Occiput flat. Median longitudinal furrow distinct. Compound eyes small and oval, its length about two times that of genae. Antennae short, with three distinct segments; scapus oval in dorsal view, more or less triangle-shaped in cross section, larger than compound eyes, about three times longer than pedicellus; pedicellus minute and indistinct, knob-like, smaller than compound eyes; third segment generally cylindrical, apices blunt, tapering basally, about three times longer than scapus, inner margin elevated medially, first half of inner margin with minute spine-like bristles. Thorax with inconspicuous granulations. Pronotum trapezoidal, expanded posteriorly, wider than head; anterior margin weakly incurved, posterior margin truncate, lateral margins thickened; transverse sulcus indistinct, longitudinal sulcus distinct. Mesonotum nearly square, slightly expanded posteriorly, anterior margin almost as long as posterior margin, shorter than mesofemora; median longitudinal carina distinct, with minute pits along lateral margins. Metanotum rectangular, wider than pronotum, wider than long, median longitudinal carina distinct, with minute pits along lateral margins. Abdomen flattened, tapering posteriorly. Distinctly carinate mediolongitudinally. Wrinkled, with minute pits along lateral margins, also with sparse granulations. Median segment narrow, wider than long. Second and third tergites wider than mesonotum, as wide as metanotum, fourth tergum to anal segment not wider than second tergum. Seventh sternum lacking noticeable praeopercular organ. Eighth tergum longer than ninth tergum. Anal segment as long as eighth tergum, constricted posteriorly, posterior margin rounded. Supra-anal plate indistinct. Subgenital plate scoop-shaped, short, flattened, posterior margin pointed, reaching anterior margin of anal segment. Cerci cylindrical, straight, apices rounded and surpassing posterior margin of anal segment. Legs slender and long. Densely covered with minute bristles. Femora roughly as long as corresponding tibiae. Profemora incurved basally. Anterodorsal, posterodorsal, anteroventral and posteroventral carinae of femora and tibiae waved with indistinct elevations.

Distribution.-

China (Yunnan).

Notes.-

The male is unknown. No food plant eaten by the collected specimens was observed. No egg was collected and further material is necessary for understanding the relationship with other species.

Etymology.-

This new species is named in honor of Professor Li Li-Zhen (Shanghai, China) for his contributions to Chinese entomology.
