Diagnosis

Kokeshia hilli sp. nov. can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII introduced into a flattened, nearly quadrangular process, left posterolateral margin of the process with a raised projection, which bearing about 7 thick, basal-curved spiniform microtrichia; right posterolateral margin of the process with about seven parallel, thick, basalcurved spiniform microtrichia. Right hemitergite VIII with a long, rodlike process projecting posteriad ( Figs 11D–E, G View Fig , 12 View Fig A−B).

Etymology

The species epithet is derived from and dedicated to Mr Lionel Hill (Tasmanian Department of Primary Industry, Water and Environment, Australia), recognizing his contributions to the study of taxonomy of Dipsocoromorpha (mainly in the Australian region).

MACROPTEROUS. Small sized (about 1.22‒1.36 mm).

COLORATION. Body brown, appendages yellowish brown ( Fig. 11A–C View Fig ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.58–0.68 × length of maximum width across eyes.

THORAX. Humeral width 1.72‒1.88 × 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. 26F View Fig ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical. Tergite VIII subdivided into two hemitergites, posterior margin of left hemitergite VIII ( Figs 11D–E, G View Fig , 12 View Fig A−B) introduced into flattened, nearly quadrangular process, left posterolateral margin with raised projection, bearing about 7 thick, basal-curved spiniform microtrichia; right posterolateral margin of process with about 7 parallel, thick, basal-curved spiniform microtrichia. Basal portion of process with numerous small round pits and micro teeth. Right hemitergite VIII with long, stick shaped process projecting posteriad ( Figs 11 View Fig E−F, 12E).

GENITALIA. Pygophore slightly asymmetrical, dorsal surface with dense microtrichia, posterior area with relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 11E View Fig , 12G‒H View Fig ) with broadly blunt laminate extension directed dorsal near base, and with flattened and relatively broad distal projection, and slightly curved inward from middle of it; right paramere ( Figs 11E View Fig , 12C‒D View Fig ) with flattened, round and relatively slender distal projection. Apical portion of phallus ( Figs 11D‒E View Fig , 12F View Fig ) tubular, slender, forming less than one and a half coils outside of pygophore.
