Description. Length 7.9–9.4 mm, width 4.1–5.5 mm. General color yellow, but head, scutellum, femora, tarsi, and apices of tibiae black, antennae apically paler; elytra greenish or purplish bronze ( Figs 1 View FIGURES 1 C–1D). Antenna filiform, relatively longer in male ( Fig. 5 View FIGURES 5 A), as long as body, antennomeres III–V apically widened, length ratios of antennomeres III to XI about 1.0: 1.3: 1.3: 1.4: 1.4: 1.3: 1.3: 1.3: 1.6, and length to width ratios of antennomeres III to XI about 2.5: 3.5: 3.5: 4.0: 4.2: 4.5: 4.6: 5.2: 7.7; relatively shorter in female ( Fig. 5 View FIGURES 5 B), about 0.9x as long as body, antennomeres III–V apically widened, length ratios of antennomeres III to XI 1.0: 1.1: 1.2: 1.0: 1.1: 1.1: 1.0: 1.0: 1.4, and length to width ratios of antennomeres III to XI 3.2: 3.6: 3.8: 3.6: 4.0: 4.2: 4.3: 4.4: 5.9. Apical margin of abdominal ventrite V with two well developed incisions in male, surface with deep, wide, longitudinal groove, apically expanding into most of area between incisions; apical margin of ventrite IV with very small incision midway ( Fig. 5 View FIGURES 5 E). Aedeagus concave and basally widened, weakly curved in lateral view; apico-lateral angles obtusely angulate, narrow in lateral view, base obtusely angulate; middle of apical margin with a long, broad tube-like process, wide in lateral view, apex with median notch; dorsal process subapically and strongly swollen in lateral view but weakly swollen in dorsal view, apex pointed and triangulate in lateral view ( Figs 5 View FIGURES 5 C–5D). Abdominal ventrite V not modified in female, apical margin truncate, disc without depression ( Fig. 5 View FIGURES 5 F); apical of margin of ventrite IV straight. Gonocoxae reduced. Ventrite VIII ( Fig. 5 View FIGURES 5 H) heartshaped, with short spiculum, with scarce elongate setae along apical margins of triangulate processes. Tergite VIII ( Fig. 5 View FIGURES 5 G) with apex rounded and dense setae on disc. Receptacle of spermatheca ( Fig. 5 View FIGURES 5 I) weakly swollen, barely separated from pump, pump much narrower and longer, sharply curved; proximal spermathecal duct long and narrow.
Diagnosis. See diagnosis of Siemssenius cheni sp. nov.
Host plant. Lonicera acuminata Wall., 1832 (Caprifoliaceae) ( Figs 3 View FIGURES 3 B–3C).
Distribution. Two localities at mountain areas in south Taiwan (Nantou and Chiayi counties) where it is sympatric with S. rufipennis ( Chûjô, 1962) ( Fig. 4 View FIGURE 4 ).
