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) with reticulate coriaceous microsculpture, covered with sparse setiferous punctures; setae produced from inside punctures (Fig. 37A); 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). 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).
Pronotum (Fig. 35A, 36B) 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); distance between punctures in central portion 2–4 times their own diameter, denser laterally. Setae produced from inside punctures (Fig. 37B).
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), 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); 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, 36C). Mesepisternum sparsely furnished with setiferous punctures (Fig. 35B, 36C). Surface of metaventrite with reticulate coriaceous microsculpture, (Fig. 37C), central area covered with setiferous punctures, denser in lateral areas, setae produced anterior to puncture (Fig. 37C). Surface of sternites with reticulate coriaceous microsculpture, sparsely covered with setiferous punctures. In male, posterior margin of 7th sternite evenly curved (Fig. 36D). In female, posterior margin of 7th sternite straight, but bisinuate on central portion (Fig. 36E).
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 A–F: 8th sternite furnished with setae, cylindrical, membrane long, allowing for posterior horizontal extension (Fig. 38E, F); spiculum fan-shaped (Fig. 38D); median struts of median lobe approximately 3.0 times as long as median lobe (Fig. 38A); apex of median lobe pointed and inclined to one side (Fig. 38B); paramere not developed (Fig. 38C).
Spermatheca as shown in Fig. 38G.
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.
