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.
