Distribution. Vietnam: Tamdao; China: Yunnan.

Remarks. By comparing the type specimens of Caryanda aurata with C. tamdaoensis from Vietnam, based on the substantial similarities in the external morphology and male genitalia structures, both species are proven to be conspecific. They share the following diagnostic characteristics: head and pronorum blue (male) or green (female) in dorsal view; hind femora with basal half yellowish and apical half reddish in both sexes; epiphallus with lophi nearly parallelogrammic in posterior view and distal-inner corner nearly rectangular; phallic complex with cingular valves and apical penis valves lathy, upcurved, distally tapering, and with a beak-shaped apex in lateral view; posterior margin of female subgenital plate roundly projected at the middle. Therefore, a new synonymy is proposed here according to Article 23 of the Code of Zoological Nomenclature (ICZN, 1999).
