Diagnosis

The male of K. weirauchae sp. nov. is similar to K. caii sp. nov., but can be recognized from the latter by tergite VIII subdivided into two hemitergites, left hemitergite VIII with a curved, finger-shaped process, with about six thick spiniform microtrichia at ventral side ( Figs 21D‒G , 22A, H ).

Etymology

The species epithet is derived from and dedicated to Prof. Christiane Weirauch (Department of Entomology, University of California, Riverside, USA), recognizing her contributions to the study of taxonomy, morphology and phylogeny of Heteroptera and Dipsocoromorpha .

MACROPTEROUS. Small sized (about 1.22‒1.30 mm).

COLORATION. Body brown, appendages yellowish brown ( Fig. 21A–C ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.60–0.64 × length of maximum width across eyes.

THORAX. Humeral width 1.72‒1.85 × 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. 27C ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical. Tergite VIII subdivided into two hemitergites, left hemitergite VIII with curved, finger-shaped process, with about six thick spiniform microtrichia at its ventral side; besides, numerous semi-erect microtrichia at its surface, and ends of microtrichia unbranched or split into two to four branches. Basal portion of process with sparsely short microtrichia ( Fig. 21D–E, G ). Right hemitergite VIII with triangular posterolateral portion projecting posteriad ( Figs 21F , 22G ).

GENITALIA. Pygophore simple, asymmetrical, dorsal surface with small, relative dense round projections and short setae, posterior area with relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 21E , 22C‒D ) with near round laminate extension directed dorsal near base, and with flattened and broad distal projection, and slightly curved inward; right paramere ( Figs 21E , 22E‒F ) with flattened, blunt distal projection. Apical portion of phallus ( Figs 21D‒E , 22G ) slender and tubular, forming more than two and a half coils outside of pygophore.

Female

Unknown.

Distribution

Yunnan Province, China ( Fig. 32 ).
