Diagnosis

Kokeshia bui sp. nov. can be recognized from other species of Kokeshia by male hemitergite VIII ( Figs 5D‒G View Fig , 6A‒B View Fig ) elongate, the left lateral margin slightly concave from about ⅓ of its apex, the posterior portion with an elongated triangular process, surpassing posterior margin of pygophore, right lateral margin of it with about nine subparallel, thick spiniform microtrichia.

Etymology

The species epithet is derived from and dedicated to Prof. Wenjun Bu (Institute of Entomology, Nankai University, China), recognizing his contributions to the study of taxonomy, phylogeny and biogeography of Heteroptera , and the taxonomy of Cecidomyiidae ( Diptera ).

MACROPTEROUS. Small sized (about 1.17‒1.24 mm).

COLORATION. Body brown, appendages yellowish brown ( Fig. 5A‒C View Fig ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.63–0.68 × length of maximum width across eyes.

THORAX. Humeral width 1.67‒1.78 × 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 distinctly darker than wing surface, other veins darker than wing surface ( Fig. 26C View Fig ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical. Tergite VIII subdivided into two hemitergites, left hemitergite VIII with elongated triangular process, right margin with about 9 subparallel, thick spiniform microtrichia ( Figs 5E, G View Fig , 6 View Fig A−B). The basal portion of process bearing numerous small round projections. Short to moderate length microtrichia located at surface of process, ends of these microtrichia split into 2 to 5 branches ( Fig. 5G View Fig ). Right hemitergite VIII subtriangular, posterolateral portion projecting posteriad, with thin setae at its posterolateral margin.

GENITALIA. Pygophore slightly asymmetrical, dorsal surface densely covered with groups of setae on small, tightly connected projections, posterior area with relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 5E View Fig , 6E‒F View Fig ) with broadly rounded laminate extension directed dorsal near the base, and with flattened and elongate distal projection slightly curved inward; right paramere ( Figs 5E View Fig , 6G‒H View Fig ) with flattened and blunt distal projection. Apical portion of phallus ( Figs 5D‒E View Fig , 6D View Fig ) tubular, relatively long, forming one complete coil outside of pygophore.
