Diagnosis. Head black; antennae dark brown to reddish brown, scape black; pronotum testaceous or red brown with two pairs of black spots: one pair beside center and the other at base, scutellum yellow brown; elytra black except testaceous area near scutellum; abdomen testaceous except abdominal ventrite V largely black, sometimes ventrite II or III with black spots laterally; legs predominantly reddish brown or black, with tibiae and tarsi darker, hind tibiae reddish brown to black. Body clothed with short pale gray pubescence. Antennae almost reaching elytral apex in male, shorter in female, reaching apical 5/6th of elytra; third segment longer than scape and fourth. Prothorax slightly wider than long; pronotum slightly raised in middle, finely and densely punctured. Scutellum almost squared, slightly emarginated. Elytra nearly 3.5 times as long as humeral width, and 3.5 times as long as head and prothorax combined; disc with fine punctures. Hind femora reaching middle of abdominal segment II; hind tibiae almost 1.5 times as long as tarsi.

Male terminalia. Tergite VIII broader than long, apex truncated and slightly emarginated, densely clothed with short hairs ( Fig. 6d ); tegmen curved in lateral view; parameres elongate, mostly covered with long setae on apical half; each paramere with transverse oblique ridge covered with dense fine hairs on ventral side ( Fig. 6a–c ); median lobe 1.3 times as long as tegmen and slightly curved in lateral view; median struts nearly 3/5 times as long as whole median lobe; dorsal plate slightly longer than ventral plate; apex of ventral plate slightly pointed; median foramen rounded ( Fig. 6e ); endophallus with 2 pairs of rods on apical portion, longer pair very slender and baculiform, about 2 times as long as shorter pair ( Fig. 6f ).

Female genitalia ( Fig. 6g ): Capsule of spermatheca with sclerotized rounded apical lobe and a stalk; spermathecal duct longer than capsule; spermathecal gland extended from strongly sclerotized ring attached to spermathecal duct.

Distribution. China: Anhui (new record), Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangsu, Jiangxi, Shanghai, Sichuan, Taiwan, Zhejiang.

Remarks. It is newly recorded from Anhui province based on specimens deposited in IZCAS.

Breuning (1962) described Oberea notata var. rufoantennata Breuning based on the specimens with reddish brown antennae from Kiukiang, Chekiang. However, Kiukiang is in Jiangxi rather than Chekiang (= Zhejiang, Now). And O. notata var. kwangtungensis , based on specimens from Kwangtung, Lien-ping, with the reddish antenna and black hind tibias. Both are unavailable infrasubspecific names ( Li, Cuccodoro & Chen, 2015). Based on the examination on the specimens from Guangdong, Guangxi, the antennae are usually reddish brown and hind tibiae black.

Kurihara & Ohbayashi (2007) described O. shimomurai from Taiwan, and subsequently Kurihara (2009) redescribed O. notata mentioning that the two species were very similar, but could be distinguished by their body form and male genitalia. However, the redescription of O. notata by Kurihara (2009) is based on a female from Baoguoshi, Mt. Emei, Sichuan, which is the type locality of O. acuta , which does not have the abdominal ventrite V black. And after comparing his description and drawing of male genitalia with O. acuta , we conclude that the specimen used by Kurihara to described O. notata belongs to O. acuta . And finally, after carefully comparing the female holotype and male genitalia of O. notata with his description and drawings of O. shimomurai , we concluded that the latter is a junior synonym of O. notata .
