Neochya hirashimai (Kimoto) is similar to N. tsoui sp. nov. in having slender elytra and lateral depressions on the pronotum (Figs 2 D-F, 7) (wide elytra and lacking lateral depressions on the prnotum in others (Figs 4, 9), but differs from N. tsoui sp. nov. in having reddish brown pronotum and yellowish brown elytra, or black pronotum, black basal half and yellowish brown apical half of elytra (Fig. 7) (reddish brown pronotum and elytra in N. tsoui sp. nov. (Fig. 2 D-F )). In addition, males of both species are separated from others with serrate margin of tectum of the penis (Figs 8 C, 12 C) (smooth margin of tectum (Figs 5 C, 10 C), but males of N. hirashimai differs from those of N. tsoui with the penis widest at middle (Fig. 8 C, E) (penis widest at apical 2 / 5 in N. nitidissima (Fig. 12 C, E).	en	Lee, Chi-Feng (2020): Revision of Taiwanese species of Atrachya Chevrolat, 1836 (Coleoptera, Chrysomelidae, Galerucinae): descriptions of three new genera, two new species, and designations of three new synonyms.

Disc covered with dense, coarse punctures, moderately or strongly convex, with lateral depressions, except N. chengi sp. nov. and N. nitidissima. Anterior margin lacking marginal bead, lateral and posterior margins with marginal bead. Anterior and posterior margins without setae, lateral margins with two pairs of setae near base and apex respectively. Anterior angles moderately swollen, rectangular, posterior angles obtuse angulate, all angles with setigerous pore bearing long pale seta. Scutellum subtriangular, impunctate, glabrous, with rounded apex. Elytra ca 1.35 - 1.68 times as long as wide, almost glabrous (with indistinct, sparse, short, pale setae on humeri, lateral margins and apical slopes), parallel sided, except N. nitidissima (Fig. 9, broader in middle), covered with densely confused punctures. Humeral calli well developed. Epipleura broad at base, gradually narrowed from basal 1 / 3, abbreviated near apex (Fig. 19 D). Macropterous. Ventral surface sparsely covered with fine punctures and pale setae. Anterior coxal cavities widely open (Fig. 18 D). Prosternal process not visible between procoxae. Abdomen simple, posterior margin of last ventrite with two long incisions in males. Legs slender. All tibiae with one apical spine, the longest spine on metatibia. Protarsomeres I not modified in males. Metatarsomeres I much longer than pro- and mesotarsomeres I, much longer than II and III combined. Claws appendiculate.

(Fig. 5 C-E )); tectum broad, apical margin truncate; internal sac with only one type of endophallic spiculae (median endophallic spiculae). Gonocoxae (Figs 5 F, 8 F, 10 F, 12 F) slender, tightly conjunct medially; each gonocoxa with eight setae from near apex to apical 1 / 6, subapically widened, apex narrowly rounded, base bifurcate. Ventrite VIII (Figs 5 G, 8 G, 10 G, 12 G) weakly sclerotized except apex, with several short and long setae at apex, and several long setae at sides, spiculum elongate. Spermathecal receptaculum (Figs 5 H, 8 H, 10 H, 12 H) as slender as pump, apically tapering; pump slender and curved; sclerotized spermathecal duct extremely elongate, but base wide, followed by short slender tube with inflated areas.

Neochya nitidissima (Chujo) is similar to N. chengi sp. nov. in having wide elytra, truncate elytral apices and reduced lateral depressions on the pronotum (Figs 4, 9) (narrow elytra, rounded elytra apices and with lateral depression on the pronotum in others (Figs 2 D-F, 7) but differs from N. chengi sp. nov. in rounded elytra and having reduced punctures on the pronotum and fine punctures on the elytra (Fig. 9) (parallel sided elytra and coarse punctures on pronotum and elytra in N. chengi sp. nov. (Fig. 3 )). In addition, males of both species are separated from others with smooth margin of tectum of the penis (Figs 5 C, 10 C) (serrate margin of tectum (Figs 8 C, 12 C), but males of N. nitidissima differs from those of N. chengi with small rounded process on lateral margin of the penis (Fig. 10 C-E) (lacking small rounded process on lateral margin of the penis in N. nitidissima (Fig. 5 C-E). Atrachya bicoloripennis (Forms A and B: Fig. 9 A-E) and A. saramao (Form C: Fig. 9 E, F) have distinct color patterns which are different from typical form N. nitidissima (Form D: (Fig. 9 G, H )). All of they are synonyms with no doubt based on examination of the penis.	en	Lee, Chi-Feng (2020): Revision of Taiwanese species of Atrachya Chevrolat, 1836 (Coleoptera, Chrysomelidae, Galerucinae): descriptions of three new genera, two new species, and designations of three new synonyms.

FE167CDA4D2551EC8C21D81383383731.taxon	distribution	Distribution. Widespread in Taiwan. Most individuals with different color patterns can be separated based on distributions (Fig. 11 A) except for the single form E. Members of form A occur at high elevation (> 2000 m) in south Taiwan, including Chiayi, south Nantou, and Kaohsiung counties. Those of form B also occur at high elevation (> 2000 m) but in central Taiwan, including Hsinchu, Miaoli, north and central Nantou, Taichung and Hualien counties. Those of form C occur at middle elevations (1000 - 2000 m) in central and south and east Taiwan, including Hsinchu, Miaoli, Taichung, Nantou, Kaohsiung, Pingtung, and Hualien counties. Those of form D occur at middle elevations (1000 - 2000 m) in north Taiwan, including Taipei, Taoyuan, Hsinchu, and Ilan counties, as well as lowlands (<1000 m) in central and south Taiwan, including Yulin, Tainan, and Pingtung counties. Coexistence of two different color patterns was observed in some areas, such forms A and B at Anmashan (鞍馬山); forms B and C at Hsuehchien (雪見), Tayuling (大禹嶺), and Tunyuan (屯原); forms C and E at Peitawushan (北大武山).	en	Lee, Chi-Feng (2020): Revision of Taiwanese species of Atrachya Chevrolat, 1836 (Coleoptera, Chrysomelidae, Galerucinae): descriptions of three new genera, two new species, and designations of three new synonyms.
