Diagnosis
Kokeshia redeii sp. nov. can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII with a flattened, slender, curved, sword-shaped process, horizontally directed mesad (Figs 17D–E, G, 18A).
Etymology
The species epithet is derived and dedicated to Dr Rédei Dávid (NCHU) recognizing his contributions to the study of taxonomy and morphology of Dipsocoromorpha and Heteroptera.

MACROPTEROUS. Small sized (about 1.19‒1.25 mm).
COLORATION. Body yellowish brown to light brown, appendages yellowish brown (Fig. 17A–C). Surface, vestiture and general structures as in generic description, except mentioned below.
HEAD. Interocular distance 0.75–0.78 × length of maximum width across eyes.
THORAX. Humeral width 1.75‒1.84 × as long as middle length of pronotum. Venation of forewing in accordance with general pattern of genus. C+Sc, R+M, R and basal portion of 1An darker than wing surface, other veins slightly darker than wing surface (Fig. 27A).
ABDOMEN. Tergite VII slightly asymmetrical, right portion wider than left portion, sternite VII nearly symmetrical. Tergite VIII subdivided into two hemitergite, left hemitergite with slender, flattened, sword-shaped process horizontally directed mesad, and without thick spiniform microtrichia on its surface (Figs 17D–E, G, 18A). Right hemitergite subtriangular (Fig. 18B).
GENITALIA. Pygophore slightly asymmetrical, dorsal surface with rows of micro teeth, posterior area with about 12 relatively long setae. Parameres strongly asymmetrical, left paramere (Figs 17E, 18D‒E) with broadly rounded laminate extension directed dorsal near base, and with flattened and tapering distal projection, and nearly straight; right paramere (Figs 17E, 18G‒H) with flattened, round distal projection. Apical portion of phallus (Figs 17D‒E, 18F) tubular, short, forming one incomplete coil outside of pygophore.
Female
Unknown.
Distribution
China: Yunnan (Fig. 32).
