Types. Adorium tarsatum . Lectotype ♀ (BMNH), here designated, labeled: “ Type [p, w, circle label with red border] // 55 / 19 [h, w, circle label] // Oides / tarsata / Baly / N. China [h, blue label] // Baly Coll. [p, w]”. Number of paralectotypes is unceratain.

Adorium sordidum . Lectotype ♀ (BMNH), here designated, labeled: “SYN- / TYPE [p, w, circle label with blue border] // N. / China [h, w, circle label] // Baly Coll. [p, w]”. Number of paralectotypes is uncertain.

Oides indica . Holotype ♂ (BMNH, by monotypy), labeled: “[aedeagus glued on the card // SYN- TYPE [p, w, circle label with blue border] // Type [p, w, circle label with red border] / Baly Coll. [p, w] // N. / China [h, w] [circle label] // Oides / indica / Baly / N. China [h, g]”.

Oides chinensis . Although some of Weise’s types are located in the NHRS, others were destroyed during the World Ward II, including those of O. chinensis (Johannes Bergsten, 26.V. 2016, personal communication). To stabilize the identity of this synonym and prevent taxonomic confusion, designation of the neotype is necessary. Here one specimen housed at the NMHB is designated as the neotype ♂, labeled: “ 福建 (Fujian) / 光澤 (Guanze) / 200–300 公尺 (200–300m) / 中國科學院 (Academia Sinica) [p, w] // 1960 [p] V.3 [h] / 採集人 (collector) 金根桃 (Gen-Tao Jin) / 林揚明 (Yang-Ming Lin) [p, w] // Oides / tarsatata [h] / 鑑定者 [p] (appraiser) Baly [h, w]”.
