Remarks
The species is reported from the Chinese provinces Yunnan and Guangxi and from Myanmar for the first time. According to the original description of Dianous zhujianqingi, the main differences between this species and Dianous cyaneovirens are the different coloration and different lengths of the apical portion of the median lobe. Additionally, there was a huge distributional gap between Nepal and East China. However, with more material examined, this distribution gap is filled. The coloration of the species is found to be greatly variable: in the Nepalese populations, the metallic tint of the species varies from golden green to blackish blue, while it is golden green or blue in specimens from Myanmar and China (Guangxi and Yunnan). In the type series of Dianous zhujianqingi, all 39 specimens have a faint plumb-coloured tint, except for two specimens from Jiangxi which have a strong brassy tint. The length of the apical portion of the median lobe is also variable: the length is intermediate in specimens from Myanmar and China (Yunnan and Guangxi). For these reasons, Dianous zhujianqingi is synonymised with Dianous cyaneovirens.
