Description. Measurement. Body length: PEL, male, 3.27–3.90 mm, female, 3.38–4.11 mm. Width: EW, male, 1.81–2.09 mm, female, 1.81–2.16 mm. Biometric data are given in Table 8.

Coloration. Head fulvous. Apex of mandible black. Antenna black except first and second segments fulvous, darkened. Pronotum fulvous. Scutellum fulvous, sometimes blackened. Elytra black, represented by two white or yellow spots posteriorly, sometimes with two additional spots near posterior margin. Thorax of ventral surface black without fulvous mesoventrite and blackened mesepisternum. Sternites fulvous. Legs black, except fore tibia and fore and mid coxae which are fulvous and apical three tarsomeres which are brown.

Habitus. Body ovate.

Head ( Fig. 36A View FIGURE 36 ) with reticulate coriaceous microsculpture, covered with sparse setiferous punctures; setae produced from inside punctures ( Fig. 37A View FIGURE 37 ); frontoclypeal suture bisinuate, middle portion wide, about half width of clypeus; labrum and clypeus convex and furnished with setae; length of clypeus longer than that of labrum. Canthus large, acutely triangular but with apex rounded, with or without a few setae. Apex of mandible bifurcate and furnished with three teeth apically on inner margin; lateral angles furnished with setae ( Fig. 35D View FIGURE 35 ). Antenna long; segments short, except for first, third and fourth which are long and slender, eleventh segment pointed; all segments setous, fifth through eleventh with shorter, denser setae ( Fig. 35C View FIGURE 35 ).

Pronotum ( Fig. 35A View FIGURE 35 , 36B View FIGURE 36 ) with blunt lateral tubercles, strongly tapered towards base; groove of anterior margin distinctly impressed a narrow distance from margin, sometimes absent on median portion; posterior marginal groove undulate; lateral basal angles weakly swollen and with two to five long setae near base; surface regularly convex and with reticulate coriaceous microsculpture, densely covered with coarse setiferous punctures ( Fig. 37B View FIGURE 37 ); distance between punctures in central portion 2–4 times their own diameter, denser laterally. Setae produced from inside punctures ( Fig. 37B View FIGURE 37 ).

Elytra short, leaving apex of pygidium exposed, moderately vaulted in lateral view; lateral sides ovate, widening approaching posterior margin; dorsal surface with reticulate coriaceous microsculpture ( Fig. 37D View FIGURE 37 ), irregularly covered in dense setiferous punctures, punctures as coarse as on pronotum and separated by 1.5–4 times their diameter; setae produced anterior to puncture ( Fig. 37D View FIGURE 37 ); sutural and lateral grooves from elytral base to apex complete; basal areas of elytra weakly convex on either side of suture; humerus strongly protruding anteriorly; epipleuron narrow. Scutellum trapezoidal, with setae.Disc of mesoventrite furnished with a few setiferous punctures; mesosternal process densely furnished with setiferous punctures ( Fig. 35B View FIGURE 35 , 36C View FIGURE 36 ). Mesepisternum sparsely furnished with setiferous punctures ( Fig. 35B View FIGURE 35 , 36C View FIGURE 36 ). Surface of metaventrite with reticulate coriaceous microsculpture, ( Fig. 37C View FIGURE 37 ), central area covered with setiferous punctures, denser in lateral areas, setae produced anterior to puncture ( Fig. 37C View FIGURE 37 ). Surface of sternites with reticulate coriaceous microsculpture, sparsely covered with setiferous punctures. In male, posterior margin of 7th sternite evenly curved ( Fig. 36D View FIGURE 36 ). In female, posterior margin of 7th sternite straight, but bisinuate on central portion ( Fig. 36E View FIGURE 36 ).

Legs densely furnished with setae; tibial setae becoming longer and denser apically. Hind femora thickened. Fore tibiae straight; mid tibiae bowed on apical half; hind tibiae weakly bowed and feebly widened near apex; mid and hind tibiae with a sharply defined and finely crenulate carina along external face. Apex of protibia with one spur; apices of meso- and metatibiae with two spurs. Tarsi distinctly shorter than tibiae, basal three segments gradually widened apically.

Male genitalia as shown in Fig. 38 View FIGURE 38 A–F: 8th sternite furnished with setae, cylindrical, membrane long, allowing for posterior horizontal extension ( Fig. 38E, F View FIGURE 38 ); spiculum fan-shaped ( Fig. 38D View FIGURE 38 ); median struts of median lobe approximately 3.0 times as long as median lobe ( Fig. 38A View FIGURE 38 ); apex of median lobe pointed and inclined to one side ( Fig. 38B View FIGURE 38 ); paramere not developed ( Fig. 38C View FIGURE 38 ).

Spermatheca as shown in Fig. 38G View FIGURE 38 .

Host plant. Euonymus carnosus Hemsl. [Japanese name: Kokutengi].

Remarks. Zeugophora flavonotata was recorded in Taiwan by Lee in 2006, but upon examining Taiwanese specimens, I found them to be a separate, undescribed species.
