Description. Measurement. Body length: PEL, male, 3.12–4.10 mm, female, 2.94–4.43 mm. Width: EW, male, 1.54–2.21 mm, female, 1.41–2.35 mm. Biometric data are given in Table 1.

Coloration (Fig. 3 A–O). Body reddish orange. Head usually reddish orange, sometimes black on vertex (fig. 3D–O). Apex of mandible black. Antennae black except first and second segments. Color pattern of pronotum various: without black spot (Fig. 3A, B); mostly black (Fig. 3 H–M, O); or central area with a black spot (Fig. 3C, D, F). Scutellum orange or black. Elytra usually reddish orange, but pattern can vary: in many cases, represented by two black-bordered white or yellow spots posteriorly (Fig. 3 B–E). Meso- and metepisterna black. Metaventrite black except central area. Dorsal surface of fore femora blackened (Fig. 3B, C, H–N) or fully testaceous (fig. 3A, D, F, G, O). Dorsal surfaces of middle and hind femora black; ventral surfaces of hind femora black except posterior half.

Habitus. Body ovate.

Head (Fig. 5A) covered with reticulate coriaceous microsculpture, and sparse setiferous punctures; setae produced from inside punctures (Fig. 6C); 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; apex of clypeus weakly lined. Canthus large, acutely triangular but apex rounded, furnished with a few setae. Apex of mandible bifurcate and furnished with two teeth apically on inner margin; lateral angles furnished with setae (Fig. 4D). Antennal insertion marginate. Antenna long; segments short, except for first, third and fourth which are long and slender, eleventh segment pointed; all segments setous, fifth through eleventh segments with shorter, denser setae (Fig. 4C).

Pronotum (Fig. 4A, 5B) with blunt lateral tubercles, strongly tapered towards base; groove of anterior margin distinctly impressed a narrow distance from margin, but absent on median portion; posterior marginal groove undulate and complete; lateral basal angles weakly swollen, with two to five long setae near base; surface regularly convex, with reticulate coriaceous microsculpture, densely covered with coarse setiferous punctures (Fig. 6B); distance between punctures in central portion 1–1.5 times their own diameter, denser laterally. Setae produced from inside punctures (Fig. 6B).

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. 6D), irregularly covered with dense setiferous punctures which are as coarse as on pronotum and separated by 1–3 times their diameter; setae produced just anterior to punctures (Fig. 6D); sutural and lateral grooves complete from elytral base to apex; basal areas of elytra weakly convex on either side of suture; humerus strongly protruding anteriorly; epipleu- ron narrow. Scutellum trapezoidal, with setae.

Disc of mesoventrite sparsely furnished with setae and no punctation; process densely furnished with setiferous punctures (Fig. 5C). Mesepisternum furnished with a few setiferous punctures (Fig.5C). Surface of metaventrite with reticulate coriaceous microsculpture (Fig. 6A), and central area covered with setiferous punctures, lateral area more densely covered with setiferous punctures; setae produced from inside punctures (Fig. 6A). Surface of sternites with reticulate coriaceous microsculpture, sparsely covered with setiferous punctures. In male, posterior margin of 7th sternite evenly curved (Fig. 5D). In female, posterior margin of 7th sternite straight, but bisinuate on central portion (Fig. 5E).

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, and basal three segments gradually widened apically.

Male genitalia as shown in Fig. 7 A–F: 8th sternite furnished with setae, cylindrical, membrane long, allowing for posterior horizontal extension (Fig. 7E, F); spiculum fan-shaped (Fig. 7D); median struts of median lobe ap- proximately 2.5 times as long as median lobe (Fig. 7A); apex of median lobe pointed and inclined to one side (Fig. 7B); paramere not developed (Fig. 7C).

Spermatheca as shown in Fig. 7G.

Host plant. Euonymus alatus (Thunb.) Siebold f. alatus [Japanese name: Nishikigi] (Chûjô & Kimoto, 1961; Takizawa, 2006); Euonymus sieboldianus Blume [Japanese name: Mayumi] (Chûjô & Kimoto, 1961; Takizawa, 2006); Euonymus lanceolatus Yatabe [Japanese name: Murasaki-mayumi] (Suzuki & Matsumura, 2006; Takizawa, 2006); Euonymus oxyphyllus Miq var. oxyphyllus [Japanese name: Tsuribana] (Kimoto & Takizawa, 1994; Takizawa, 2006); Euonymus melananthus Franch. & Sav.

Remarks. Zeugophora . annulata is easily distinguished from other Japanese species by the above-mentioned elytral color pattern. Only coloration for Japanese specimens were examined and illustrated in this study though the pattern may vary further in foreign populations (Fig. 3).
