( Figs. 11A–D , 13D–L )

Mimela hauseri Ohaus, 1943: 85 , fig.7 [original description, type locality: China, Kanton, Shinchow; Mimela (s. str.), xanthorhina - group]; Machatschke 1957: 103 [catalogued, chinensis -group]; Machatschke 1972: 179 [catalogued, chinensis -group]; Lin 1993: 51, fig. 36 (in text), pl. V, figs. 44–45, pl. XIV, fig. 35, pl. XX, fig. 27 [redescription, recorded from China: Guangxi, Guizhou, Hunan, Sichuan, Yunnan]; Zorn 2006: 268 [catalogued, recorded from the Oriental Region]; Krajčik 2007: 85 [catalogued]; Zorn & Bezděk 2016: 345 [catalogued].

Type material examined. None. The identification is based on the original description and Lin (1993).

Additional material examined (7♂♂, 6♀♀). CHINA: Guangdong : 2♀♀ ( SCAU), Yunfu City, Luoding, Pingtang Town , Julongdong 99m, 111°44′45″E 22°43′38″N 2016.V.20, light trap, Xiao-Ning Zhang leg. ; 1♀ ( ZMPC), Shaoguan City, Nanling Nature Reserve , 2021.V.24-28 ; Guangxi: 3♂♂ ( ZMPC), Laibin City, Jinxiu County, Dayaoshan (foot), 2020.IV.27 Chun-Fu Feng leg. ; 1♂, 2♀♀ ( ZMPC), Guilin City, Mt. Maoershan 2018. VI local collector leg .; Guizhou: 1♂ ( SYSU), Jiangkou, Shengxisi , 1984.VI.19 / En-017909 ; 1♀ ( SYSU), Jiangkou, Agricultural Science Institute , 1984.VI.8 / En-017908 ; Chongqing (formerly a part of Sichuan): 1♂ ( ZMPC), Beibei Dist., Xiema Town, Renhe Village , Mt. Jinyunshan (foot), 2014.V.17, Fang-Ling Qiu leg. ; Yunnan: 1♂ ( CCPC), Honghe Pref., Jinping, Biaoshuiyan , 2010.IV.27, Xiao-Dong Yang leg.

Remarks. Like the preceeding Mimela foveola Benderitter, 1929 , M. hauseri is another species with variable male genitalia ( Fig. 13D–L ). The variation can be geographically but the material accessible from some localities are quite underrepresented. Male genitalia of specimens collected from Jinxiu, Guangxi matches that in original description. The diagnostic features of M. hauseri are its metallic dorsal surface and narrow lateral carinae of elytra. The differences from its closest sibling Mimela admixta new species are in the differential diagnosis of the latter. Another metallic species in this subgroup is Mimela latimarginata new species, which has metallic green meso- and metathoracic surfaces as well as broad and abruptly obsolete lateral carinae (narrower and gradually obsolete in M. hauseri and M. admixta ).

This species was collected in Biaoshuiyan, Yunnan, ca. 50km southwestern to Daweishan, type locality of M. admixta new species. However, this widespread species occurs in lower altitude of under 1,800m. The record in Sichuan ( Lin 1993) is doubtful because of the subsequent separation of Chongqing. Unfortunately that no precise locality was provided by Lin. The record for “ORR” ( Zorn 2006; Zorn & Bezděk 2016) was based on material from northeastern Laos and northern Vietnam (Carsten Zorn, personal communication, 2021).

Distribution. China: Chongqing, Guangdong, Guangxi, Guizhou, Yunnan, Sichuan (?); Laos; Vietnam.
