Description. Measurements. Males: 3.6–4.1 mm (holotype 3.9 mm), females: 3.7–4.5 mm. Body (Fig. 87) elongate, parallel, dorsal side glabrous, elytra with sparse short setae on apical and lateral slopes. Body, antennae and legs metallic bluish-black, extreme apical margin of femora brownish, male abdomen yellow with ventrite I black (rarely only anterior margin of ventrite I darkened), female abdomen completely yellow.
Male (holotype). Anterior part of head lustrous with setae on anterior margin of clypeus and along lateral margins of nasal keel. Vertex microsculptured. Interantennal space 1.20 times as wide as transverse diameter of antennal socket. Interocular space wide, 2.57 times as wide as transverse diameter of eye. Antennae filiform, 0.62 times as long as body, length ratio of antennomeres equals 10-6-7-10- 10-10-10-9 -9-9-12.
Pronotum lustrous, 1.33 times as wide as long, widest in anterior third, covered with fine punctures. Anterior margin slightly concave, lateral margins moderately rounded, posterior margin widely convex. Anterior margin with very fine border, lateral and posterior margins moderately bordered. Anterior angles sharp, swollen, with setigerous pore, posterior angles obtusangulate, distinct but not pointed, with setigerous pore, all pores bearing long pale seta, additional short setae visible on anterior third of lateral margins.
Elytra long 1.80 times as long as wide and 0.72 times as long as body, parallel.
Protarsomere I subtriangular, slightly extended apically, inner apical angle slightly prolonged. Length ratio of protarsomeres I, II, III and V equals 10-6-4-7, of metatarsomeres I, II, III and V equals 12-6-5-9.
Prosternal process not visible between procoxae. Posterior margin of last ventrite with two deep incisions (Fig. 122).
Aedeagus symmetrical, middle part slightly divergent apically, apex triangular strongly bent down, with the tip rounded (Fig. 119). Internal sac relatively simple, with only one long thin sclerite (Fig. 128).
Female. Interocular space wider, 2.85 times as wide as transverse diameter of eye. Last ventrite widely rounded with shallow anteroapical emarginations (Fig. 124). Pygidium subtriangular with widely rounded lateral margins and apex (Fig. 123). Sternite VIII transversely oval with setae along anterior margin, tignum slender 2.1 as long as sternite VIII (Fig. 121). Spermatheca: nodulus gradually convergent to to C-shaped cornu, proximal spermathecal duct straight, slightly wider basally (Fig. 120).
Variability. Male antennae 0.61–0.70 times as long as body. Male pronotum 1.30–1.35 times as broad as long.
Distribution. Taiwan.
Biology. Unknown.
Etymology. Dedicated to Haruo Takizawa, well known specialist in Chrysomelidae and the collector of the part of the type series.
Differential diagnosis. Charaea haruoi sp. nov. is closely related to Ch. shirozui. Both species share an elongate and relatively flat body and similar structure of aedeagus having the apical quarter subtriangular and bent down, including the same simple internal sac possessing one long, thin sclerite. The males of both species can be separated by the black ventrites I in Ch. haruoi sp. nov. (yellow in Ch. shirozui) and also by the shape of protarsomeres I which are subtriangular in Ch. haruoi sp. nov. but possess distinctly rounded lateral margins in Ch. shirozui. The aedeagus of Ch. haruoi sp. nov. is slightly divergent anteriorly and the bent apex is shorter, while Ch. shirozui has the aedeagus slightly convergent anteriorly and the bent apex is longer. In lateral view the ventral side of the aedeagus of Ch. haruoi sp. nov. is more convex (Figs 70, 119). Sclerotized parts of the internal sac in Ch. haruoi sp. nov. are always black and orange to brown in Ch. shirozui (Figs 91, 128).
Females of both species can be distinguished by the shapes of the last ventrites which are remarkably pointed at the apex; with deep anterolateral incisions in Ch. shirozui and rounded apex with shallow anterolateral emarginations in Ch. haruoi sp. nov. (Figs 75, 124). Spermathecae of both species are similar. The only difference can be found on the proximal duct, which is gradually widened basally in Ch. shirozui and abruptly widened in Ch. haruoi sp. nov. (Figs 71, 120). Sternite VIII of Ch. shirozui is very small and elongate, but large and transversely oval in Ch. haruoi sp. nov. (Figs 72, 121).
Due to the black ventrite I, the males of Ch. haruoi sp. nov. resemble males of Ch. pseudoakkoae, but the species differ in dorsal coloration (metallic bluish black in Ch. haruoi sp. nov., metallic green in Ch. pseudoakkoae) and by completely different structures of the aedeagi (Figs 58, 119).
