Diagnosis

Kokeshia renae sp. nov. can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII with a subtriangular process, with numerous semi-erect microtrichia on surface, and the ends of these microtrichia unbranched or split into two to four branches ( Figs 19 D−E, G, 20A−B). Right hemitergite VIII with a subtriangular posterolateral portion projecting posteriad, which bearing numerous short to relative long microtrichia at its apex ( Figs 19 D−F, 20B−C).

Etymology

The species epithet is derived from and dedicated to Prof. Shuzhi Ren (Institute of Entomology, Nankai University, China), recognizing her contributions to the study of egg morphology of Heteroptera and the study of taxonomy of Chinese Heteroptera .

MACROPTEROUS. Small sized (about 1.18–1.23 mm).

COLORATION. Body light brown to brown, appendages yellowish brown ( Fig. 19A–C ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.68–0.71 × length of maximum width across eyes.

THORAX. Humeral width 1.73‒1.85 × 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. 27B ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical.Tergite VIII subdivided into two hemitergites, left hemitergite VIII with subtriangular process, with numerous semi-erect microtrichia on surface, ends of microtrichia unbranched or split into two to four branches ( Figs 19 D−E, G, 20A−B). Basal portion of the process with sparsely short microtrichia. Right hemitergite VIII with subtriangular posterolateral portion projecting posteriad, bearing numerous relative long microtrichia at apex ( Figs 19 D−F, 20B−C).

GENITALIA. Pygophore simple, asymmetrical, dorsal surface with relative dense small round projections and short setae, posterior portion of with relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 19E , 20F‒G ) with broadly rounded laminate extension directed dorsal near base, and with flattened and broad distal projection, and curved inward; right paramere ( Figs 19E , 20H‒I ) with flattened, round distal projection. Apical portion of phallus ( Figs 19D‒E , 18E ) tubular, forming more than one coil outside of pygophore.

Female

Unknown.

Distribution
