Coloration. Surface shiny. Body fulvous. Head fulvous, blackened dorsally. Apex of mandible black. Antennae fulvous. Pronotum fulvous with black patch on central portion. Scutellum fulvous. Elytra fulvous with black patches on anterior corners and posterior halves of elytra, anterior and posterior patches sometimes connected. Ventral surface of head and prosternum fulvous, thorax and abdomen black. Leg fulvous except hind black coxa. Habitus. Body oblong. Head ( Fig. 46A ) covered with sparse setiferous punctures; setae produced from inside punctures ( Fig. 47A ); frontoclypeal suture bisinuate, middle portion narrow, about one third width of clypeus; labrum and clypeus convex and furnished with setae; length of clypeus longer than that of labrum. Anterior margin of clypeus weakly lined ( Fig. 46A ). Canthus small, obtusely triangular with apex rounded, furnished with a few setiferous punctures. Apex of mandible bifurcate and furnished with one large tooth apically on inner margin; lateral angles furnished with setae ( Fig. 45D ). Antenna weakly clavate; antennal segments short, except for first, third and fourth which are long and slender, eleventh pointed; first through fourth segments with setae, other segments with tiny dense setae ( Fig. 45C ). Pronotum ( Fig. 45A , 46B ) with blunt lateral tubercles, strongly tapered towards base; posterior marginal groove undulate, but lateral sides ambiguous; lateral basal angles weakly swollen; surface regularly convex, covered with coarse setiferous punctures ( Fig. 47B ); distance between punctures 0.5–4.0 times their own diameter, sparser on posterior half of longitudinal median portion. Setae produced from inside punctures ( Fig. 47B ). FIGURE 44 . Zeugophora cupka , sp. nov. A. Holotype, female, dorsal view; B. Ditto, ventral view; C. Ditto, lateral view; D. Z. cupka on the leaf of Populus suaveolens in nature; E. Habitat: Kinka-tôge, Rubeshibe, Hokkaidô, Japan. Elytra long, leaving apex of pygidium exposed, moderately vaulted in lateral view; lateral sides subparallel; surface with reticulate coriaceous microsculpture, irregularly covered with dense setiferous punctures, punctures coarsely separated by 2–4 times their diameter; setae produced from anterior inner margin of puncture, posterior two-thirds of punctures deep ( Fig. 47D ); sutural and lateral grooves complete from elytral base to apex; basal areas of elytra weakly convex on either side of suture; humerus protruding anteriorly; epipleuron narrow. Scutellum trapezoidal, with setae. Disc of mesoventrite rugose; process short, furnished with setiferous punctures ( Fig. 45B , 46C ). Mesepisternum furnished with setiferous punctures, except near suture separating it from mesepimeron ( Fig. 45B , 46C ). Central area of metaventrite sparsely and lateral area densely covered with setiferous punctures ( Fig. 47C ), setae produced anterior to shallow punctures ( Fig. 47C ); posterior margin of mid coxal insertion markedly punctate. Surface of sternites with microsculpture, sparsely covered with setiferous punctures. In male, posterior margin of 7th sternite evenly curved ( Fig. 46D ). In female, apex of pygidium concave; posterior margin of 7th sternite straight, but bisinuate on central portion ( Fig. 46E ). FIGURE 45. Zeugophora cupka sp. nov. A. Pronotum, dorsal view; B. Thorax, ventral view; C. Antenna; D. Mandible, left part. Scales. A–C. 1 mm; D. 100μm. Legs furnished with setae; tibial setae becoming denser and longer apically. Hind femora thickened. Tibiae straight; mid and hind tibiae with sharply defined and finely crenulate carina along external face, apex with two spurs. Tarsi distinctly shorter than tibiae, basal three segments gradually widened apically. Male genitalia as shown in Fig. 48 A–F: 8th sternite furnished with setae, short, oblique anteriorly, membrane and sclerotized portion narrow ventrally, allowing for downward extension ( Fig. 48E, F ); apex of spiculum three branched, central branch furnished with tiny setae ( Fig. 48D ); median struts of median lobe approximately 1.5 times as long as median lobe ( Fig. 48A ); apex of median lobe pointed ( Fig. 48B ), lateral side flattened ( Fig. 48A ); paramere well developed ( Fig. 48C ). Spermatheca as shown in Fig. 48G . Etymology . The species name, cupka (cúpka) means "east" in the Ainu language of Hokkaido , Japan . Host plant . Populus suaveolens Fisch [Japanese name: Doronoki].

External traits of Zeugophora cupka are somewhat similar to Z . turneri Power, 1863 which is distributed in northern, north-central, and eastern Europe to Siberia and Mongolia . I examined external traits and male and female genitalia of both species. They can be distinguished from the latter by the following characters: 1) body coloration; Z . turneri is fully testaceous while Z . cupka has some color variation as described above; 2) shape of median lobe; in Z . turneri , median lobe is wider and apex is narrower than in Z . cupka ( Fig. 48B, I ); and 3) shape of spermatheca; in Z . turneri , the shape of the spermathecal capsule is vertically long, while that of Z . cupka is short and the posterior portion is swollen ( Fig. 48G, J ).
