Redescription. Length 4.2–6.4 mm, width 1.4–2.5 mm. General color ( Figs 11View FIGURES 11 A–11F) yellowish brown; antennae brown or dark brown; occiput usually dark brown with metallic iridescence; pronotum brown or dark brown with metallic iridescence; elytra brown but may be metallic blue laterally or entirely metallic blue; metathoracic ventrites metallic blue; sometimes hypomeron, tibiae, and tarsi darker. Vertex with reticulate microsculpture. Antennae filiform in males ( Fig. 12AView FIGURES 12), antennomeres IV–VIII slightly curved, length ratios of antennomeres I–XI 1.0: 0.3: 0.9: 1.2: 1.5: 1.4: 1.6: 1.6: 1.6: 1.5: 1.5, length to width ratios of antennomeres I–XI 2.8: 1.2: 2.6: 3.6: 4.5: 4.3: 4.9: 5.4: 5.4: 6.8: 6.6; antennomeres straight and more slender in females ( Fig. 12BView FIGURES 12), length ratios of antennomeres I–XI 1.0: 0.3: 0.8: 1.0: 1.1: 1.0: 1.0: 1.0: 1.0: 0.9: 1.0, length to width ratios of antennomeres I–XI 3.7: 1.8: 3.3: 5.2: 4.8: 4.6: 5.3: 5.0: 5.2: 4.9: 5.4. Pronotum transverse, 1.3x wider than long, disc with one pair of lateral depressions, reduced reticulate microsculpture, and with sparse, fine punctures; lateral margin basally narrowed; apical and basal margins subtruncate. Elytra elongate and parallelsided, 2.0–2.2x longer than wide; disc with reticulate microsculpture, dense, coarse punctures, arranged into longitudinal rows, and with weak, longitudinal ridges between longitudinal rows of punctures. Apical margin of abdominal ventrite V in females ( Fig. 12HView FIGURES 12) truncate but expanded, with convex projection medially, and slightly depressed or truncate at middle. Tarsomeres I of front legs swollen in males ( Fig. 12IView FIGURES 12), subparallel in female ( Fig. 12JView FIGURES 12). Penis ( Figs 12View FIGURES 12 C–5E) extremely slender, 9.3x longer than wide; apex lanceolate, with deep, narrow median notch, parallel-sided; tectum extremely elongate from apical 1/10 to basal 2/5, apically narrowed; straight in lateral

view, curved near base; triangular sclerites small; internal sac with elongate endophallic sclerite complex, 0.5x as long as penis, composed of two sclerites, basal piece much shorter (0.6x) than apical piece, apical piece with acute apex, dorsal sclerite minute, apex acute. Gonocoxae ( Fig. 12FView FIGURES 12) elongate, slightly broadened at apical 1/6, connected from basal 1/3 to apical 1/4; apices narrowly rounded, each gonocoxa with eight setae along outer margin from apex to apical 1/6; with one pair of short lateral processes at basal 2/5. Ventrite VIII ( Fig. 12GView FIGURES 12) longitudinal and well sclerotized; disc with several long setae at sides and near apical margin, and with dense, short setae along apical margin; spiculum extremely slender. Receptacle of spermatheca ( Fig. 12KView FIGURES 12) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, broad and short.

Variation. Females display greater color variation than males. Although color patterns of some females are similar those of males ( Figs 11E, 11FView FIGURES 11), most have entirely metallic blue or bronze elytra, and yellow occiputs and pronota ( Fig. 11GView FIGURES 11). A distinct color pattern occurs to populations in Tahanshan (大漢山). Adults have entirely yellow bodies except elytra with metallic iridescence in both sexes ( Fig. 11HView FIGURES 11).

Diagnosis. Theopea kanmiyai  adults are similar to those of T. irregularis  based on indistinct longitudinal ridges on the elytra. They can be distinguished by the much broader, curved antenna in males, and sexually dimorphic color pattern that the elytra are yellowish brown with metallic green sides, pronotum and vertex metallic green in males; elytra entirely metallic green, prothorax and head yellow in females ( Fig. 11View FIGURES 11). Males of T. kanmiyai  have a relatively short basal piece (0.6x longer than apical piece) and small dorsal sclerite of the endophallus ( Figs 12View FIGURES 12 C–12D), which are different from those of T. irregularis  . The latter has a longer basal piece (1.6x longer than apical piece) and large dorsal sclerite ( Figs 9View FIGURES 9 D–9E).

Food plants. Iteaceae  : Itea parviflora; Schisandraceae  : Illicium arborescens  ; Betulaceae  : Alnus formosana  .

Distribution. Endemic to Taiwan. It is a widespread but less common species (only 160 specimens available for study) ( Fig. 10BView FIGURES 10). Adults appear at various elevations from June to October. This species is abundant locally in Tahanshan (大漢山) (55%). Most (95%) adults appear from June to August.
