Diagnosis.Adults of C. jungchani sp. nov.are similar to those of C. cheni sp. nov.with yellowish brown body, metallic green elytra and occiput, but the former species possesses a yellow pronotum and legs (metallic green pronotum, black tibiae, tarsi, and apices of femora in C. cheni), weakly widened antennae (antennomeres III-VI more than 4.0 times longer than wide) and inwardly curved tibiae of middle legs in males (strongly widened antennae (antennomeres III-VI less than 3.5 times longer than wide and straight tibiae of middle legs in males of C. cheni). The aedeagi of males of C. jungchaniand C. cheniare characterized by presence of tiny spines on the lateral or ventral discs. In C. jungchani, sparse spines are present on the lateral disc, the middle sclerite possesses a tapering apex, the apical sclerite of the endophallic sclerite complex is absent, and the apex is ventrally recurved. By contrast, the aedeagus of C. chenipossesses sparse, tiny spines on the ventral disc, a small apical sclerite, an apically widened middle sclerite of the endophallic sclerite complex, and an anteriorly directed apex.

Elytra elongate and parallel-sided, 1.9x longer than wide; disc with reticulate microsculpture, dense, coarse punctures, and several longitudinal ridges. Tarsomeres I of front and middle legs swollen in males. Penis ( Figs 10C–10D) slender, 8.8x longer than wide; subapically and slightly asymmetric; tectum elongate and weakly sclerotized; slightly curved in lateral view, with angular process at apical 1/6 of ventral surface and apical 1/5 of dorsal surface; ventral surface well sclerotized and with hollow area at apical 1/6; internal sac with three sclerites, apical sclerite elongate and apically tapering, medial sclerite wide and hooked, basal sclerite longest, apex trilobed, median lob apically tapering. Gonocoxae ( Fig. 10E) narrowly connected at apical 1/3; apices rounded, each gonocoxa with nine setae along outer margin from apex to apical 1/4.

Diagnosis.Adults of C. tsoui sp. nov.are similar to those of C. formosana(Chûjô)and C. meihuai sp. nov.with blackish brown body, metallic blue occiput, pronotum, and elytra. The former species can be distinguished by the reduced reticulate microsculpture on the pronotum (distinct in C. formosana), elytra with longitudinal ridges (lacking longitudinal ridges present in others), and slightly wider antennae in males (strongly wider antenna in males of C. meihuai). Males of C. tsoui sp. nov.are similar to those of C. formosanain possessing asymmetric apices of the aedeagi but the apices are narrowly rounded (curved to right in C. formosana) and wider, 8.8 times longer than wide (relatively slender in C. tsoui sp. nov., 10.0 times longer than wide).
Etymology.This new species is dedicated to Mei-Hua Tsou, a member of TCRT and the first to collect this new species. Food plants. Rhamnaceae: Rhamnus formosanaMatsum.( Fig. 1B); Ventilago elegansHemsl..
Remarks.Kimoto (1969) examined specimens of C. formosanacollected from Kenting and Hengchun that possessed longitudinal ridges on the elytra. Apparently, those were misidentified and should be assigned to this new species.

Occiput without reticulate microsculpture. Antennae filiform in males ( Fig. 11A), antennomeres V-VII slightly expanded, length ratios of antennomeres I–XI 1.0: 0.4: 0.7: 0.6: 0.6: 0.7: 0.7: 0.6: 0.6: 0.5: 0.6, length to width ratios of antennomeres I–XI 4.2: 2.9: 3.6: 3.7: 3.8: 3.8: 4.2: 3.9: 4.3: 3.6: 3.9; slender in females ( Fig. 11B), length ratios of antennomeres I–XI 1.0: 0.5: 0.7: 0.7: 0.7: 0.7: 0.7: 0.6: 0.6: 0.5: 0.7, length to width ratios of antennomeres I–XI 4.1: 2.9: 4.0: 4.4: 4.3: 4.3: 4.6: 4.2: 4.3: 3.7: 4.7. Pronotum transverse, 1.5x wider than long, disc convex without reticulate microsculpture, and with sparse, fine and coarse punctures; lateral margin narrower near base; apical margin slightly concave; basal margin subtruncate. Elytra elongate and parallel-sided, 1.8x longer than wide; disc with reticulate microsculpture and dense, coarse punctures; apical margin with one pair of angular processes near suture in females. Tarsomeres I of front and middle legs swollen in males. Penis ( Figs 11C–11D) extremely slender, 10.4x longer than wide; apex rounded; tectum elongate and weakly sclerotized; slightly curved in lateral view, ventral margin subapically irregular; ventral surface well sclerotized; internal sac with two sclerites, apical sclerite elongate and apically tapering; basal sclerite longest, apex trilobed, median lob apically tapering. Gonocoxae ( Fig. 11E) narrowly connected at apical 1/3; apices rounded, each gonocoxa with seven or eight setae along outer margin from apex to apical 1/4. Ventrite VIII ( Fig. 11F) transverse and weakly sclerotized; with dense, short setae along apical surface; spiculum extremely slender. Receptacle of spermatheca ( Fig. 11G) a little broader than pump; pump shallowly inserted into receptacle, narrowed near base, anterior part with transverse depressions, posterior part narrower apically, strongly curved; proximal spermathecal duct shallowly inserted into receptacle, elongate and narrow. Variation.Some specimens with dark brown pronota and possessing occiputs with strongly metallic blue reflections are similar to those of C. meihuai sp. nov.They can be distinguished by the dark brown ventral surfaces and legs (black venter and legs in C. meihuai sp. nov.).
Diagnosis.Adults of C. wulaiensis sp. nov.are similar to those of C. yuae sp. nov.with yellowish body and metallic green elytra. Males of C. wulaiensispossess straight tibiae of middle legs (curved inwards in C. yuae), much narrower aedeagi (10.4 times longer than wide) (relatively wider aedeagi in C. yuae, 6.6 times longer than wide), aedeagus with rounded apex (apex with median notch in C. yuae), and aedeagus slightly curved in lateral view (moderately curved in lateral view of C. yuae sp. nov.).
Etymology.The new species is named for one of the collecting sites near the typelocality (Chiachiuliao, ???).
Remarks. One paratypeof C. shirozuicollected from Wulai is assigned to this new species (see types). Food plants. Rhamnaceae: Rhamnus formosanaMatsum.( Fig. 1B).

Pronotum transverse, 1.5x wider than long, disc convex with reticulate microsculpture, and with sparse, fine and coarse punctures; lateral margin narrower near base; apical margin slightly concave; basal margin subtruncate. Elytra elongate and parallel-sided, 1.9x longer than wide; disc with reticulate microsculpture and dense, coarse punctures. Tarsomeres I of front and middle legs swollen in males. Penis ( Figs 13C–13D) slender, 6.6x longer than wide; apex with shallow notch; tectum elongate and weakly sclerotized; moderate curved in lateral view, ventral margin subapically irregular; ventral surface well sclerotized; internal sac with two sclerites, apical sclerite elongate and apically tapering; basal sclerite longest, apex trilobed, median lob apically tapering. Gonocoxae ( Fig. 13E) narrowly connected at apical 1/3; apices rounded, each gonocoxa with eight setae along outer margin from apex to apical 1/4. Ventrite VIII ( Fig. 13F) transverse and weakly sclerotized; with dense, short setae along apical surface; spiculum extremely slender. Receptacle of spermatheca ( Fig. 13G) slightly broader than pump; pump shallowly inserted into receptacle, separated into two parts, anterior part with transverse depressions, posterior part narrower apically, strongly curved; proximal spermathecal duct shallowly inserted into receptacle, elongate and narrow.
Diagnosis.Adults of C. yuae sp. nov.are similar to those of C. wulaiensis sp. nov.with yellowish body and metallic green elytra. Males of C. yuaepossess the inwardly curved tibiae of middle legs (straight in C. wulaiensis), much wider aedeagi (6.6 times longer than wide) (relatively slender in C. wulaiensis sp. nov., 10.4 times longer than wide), aedeagus with bifurcate apex (rounded apex in C. wulaiensis) and moderately curved in lateral view (slightly curved in lateral view of C. wulaiensis).
Etymology.This new species is dedicated to Su-Fang Yu, a member of TCRT and the first to collect this new species. Food plants. Rhamnaceae: Rhamnus nakaharae(Hayata) Hayata( Fig. 1A).
Distribution.North Taiwan(north TaipeiCounty) ( Fig. 4).
