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 ).
