Glenea coomani Pic, 1926 distributed in Vietnam, Laos and China is redescribed, and its sibling species, Glenea neohumerosa sp. n. is described from China (Guangxi, Hainan and Fujian) and North Vietnam. They are separated from each otherby differences in genitalia, and apical teeth and maculae of elytra. Another four related species and one subspecies are illustrated with short notes and new localities, and the lectotype and paralectotype of Glenea tonkinea Aurivillius, 1925 are designated. A key to the related species is presented.

Figs 25–26Due to lack of material from Taiwan, the differences between Glenea lacteomaculata Schwarzer, 1925 and Glenea lacteomaculata quadriguttata Pic, 1926 are doubtful for the authors. The specimens from Guangxi and Yunnan provinces are conspecific to Glenea lacteomaculata quadriguttata and herein the new localities are reported.

Figs 30–33Differs from Glenea pici Aurivillius in having pubescent maculae white; in having different male claws. Differs from Glenea lacteomaculata Schwarzer in having spot at middle of elytron transverse, anterior claw in mid tarsus of male with long tooth (Fig. 31).

According to Aurivillius' original description, there were multiple type specimens, deposited in “Reichsmuseum in Stockholm und Collectio Pic". In order to fix the species concept and ensure universal and consistent interpretation of this species, we designate the male specimen in MNHN as the lectotype (Figs 30–31, 8.5 mm long, 2.4 mm wide) and the female in NHRS as the paralectotype (Fig. 33) of Glenea tonkinea Aurivillius.

The record from Taiwan is doubtful. It might be based on Glenea diversenotata Schwarzer, whose taxonomic position was not clear yet.

The above species are grouped as Glenea coomani group by the following characters (not meant to be presumed synapomorphies, but rather only for identification of species having similar makings): pronotum largely black, generally with a white or yellow median stripe; body covered with pubescence instead of metallic squama (such as the metallic green maculae of Glenea pici Aurivillius, 1925); elytron black with an apical spot and 4 or 5 unequal sized spots. They differ from Glenea relicta group by elytral spots (not include the band just before apex) with unequal size and located in different position.
