description: Oberea bisbipunctata Pic, 1916   
(Fig. 7)  
 Oberea bisbipunctata Pic, 1916: 17. Type locality: Vietnam, Tonkin; Breuning, 1962: 194, fig. 14; Hua, 2002: 219; Löbl & Smetana, 2010: 297; Lin & Tavakilian, 2019: 348; Danilevsky, 2020: 428.   
 Oberea bisbipunctata ssp. discoreducta Breuning, 1969: 37. TL: Vietnam, Annam.   
 Diagnosis. Head black; antennae dark brown; pronotum testaceous or red brown with two pairs of black spots: one pair near center and the other at base; scutellum yellow brown; elytra testaceous except for apical 1/5 black; abdomen testaceous except abdominal ventrite V mostly black and abdominal ventrite I partly black; legs predominantly reddish brown, with tibiae and tarsi darker, and hind tibiae dark brown. Antennae distinctly shorter than body, reaching 3/4th of elytra; third segment longer than scape and fourth. Elytra nearly 4 times as long as humeral width, and 3.5 times as long as head and prothorax combined; elytral disc with fine punctures. Hind tibiae almost 2 times as long as tarsi.   
 Material examined. VIETNAM: Holotype, ♂, Hanoi (MNHN); 1♀, Tonkin, Hanoi, 18.v.1987. Jeanvoine leg. (MHNG); 1♀, Tonkin, Langsong (MHNG); 1♀, Vietnam, Annam (MHNG).   
 Distribution. Vietnam: Central and Northern.   
 Remarks. In the titan database, O. bisbipunctata ssp. discoreducta Breuning, 1969 is treated as subspecies. However, according to Lin & Tavakilian (2019), it is the synonym of O. bisbipunctata. According to the original description and comparison with two types, the subspecies is similar to the O. bisbipunctata, but lack of the two black premedian disc spots on the pronotum. The pronotal spots could vary within species. It is proper to be treated as the junior synonym.   
 Gressitt (1939) reported Oberea bisbipunctata as new to China based on specimens from Guangdong. However, according to the description and pictures provided by Gressitt (1939, Plate III, fig.11 & 12) and the examination of the specimens from SYSU, these specimens are clearly O. notata, whose distribution includes also “Kwangtung (Yimna Shan, Yao Shan. Lien), Szechuan (Suifu=[Yibin, now], Omei=[Emei, now]), Kwangsi (Yangso=[Yangshuo, now])” (Gressitt, 1951). The specimens from Guangdong and Guangxi recorded in Gressitt (1951) are O. notata, and those from Sichuan are most likely O. acuta. According to the description and picture (Pu, 1980, Plate XII, fig 170), the O. bisbipunctata recorded in “Economic Insect Fauna of China Fasc, 19” (Pu, 1980) belongs to O. acuta. The picture of O. bisbipunctata from California Academy of Sciences, determined by Gressitt (Bezark, 2020) belongs to O. notata. Wang (2003) reported the distribution of the species includes Liaoning, NE China, but the figure used was from Pu (1980). The distribution in China of O. bisbipunctata reported by Hua (2002) as from “NE China, Zhejiang, Guangdong, Guangxi, Guizhou, Sichuan ” is based on the mistaken records, and there are no details of his records from Zhejiang and Guizhou. And the entire specimen we examined identified as O. bisbipunctata are O. notata or O. acuta. Our conclusion is that at present there is no evidence that specimens of O. bisbipunctata were found outside of Vietnam.
