The Chinese species of [taxon-name: Dianous] group I were reviewed by Tang and Li in 2011. This group includes nine species: [taxon-name: Dianous yao] Rougemont, 1981, [taxon-name: Dianous tonkinensis] (Puthz), 1968, [taxon-name: Dianous limitaneus] Puthz, 2001, [taxon-name: Dianous viriditinctus] (Champion), 1920, [taxon-name: Dianous fengtingae] Tang & Li, 2010, [taxon-name: Dianous zhujianqingi] Tang & Li, 2010, [taxon-name: Dianous huanghaoi] Tang & Li, 2010, [taxon-name: Dianous shan] Rougemont, 1981 and [taxon-name: Dianous viridicupreus] Rougemont, 1985. Subsequently, more material was received. A study of this material yielded new locality records and a new synonymy.

Material and methods

For examination of the male genitalia, the last three abdominal segments were detached from the body after softening in hot water. The aedeagus and other dissected parts were mounted in Euparal (Chroma Gesellschaft Schmidt, Koengen, Germany) on plastic slides. Photos of sexual characters were taken with a Canon G7 attached to an Olympus SZX 16 stereoscope; habitus photos were taken with a Canon macro photo lens MP-E 65 mm attached to a Canon EOS40D camera.

The type specimens treated in this study are deposited in the following public and private collections:

China (Jiangxi, Guizhou, Guangxi, Yunnan), Myanmar, Nepal.


The species is reported from the Chinese provinces Yunnan and Guangxi and from Myanmar for the first time. According to the original description of [taxon-name: Dianous zhujianqingi], the main differences between this species and [taxon-name: 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 [taxon-name: 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, [taxon-name: Dianous zhujianqingi] is synonymised with [taxon-name: Dianous cyaneovirens].

The species is a new record for China

To accommodate [taxon-name: Dianous haraldi], the recently published key to the Chinese species of [taxon-name: Dianous] group I (Tang, Li and Cao 2012) is modified at couplet 6 as follows:
