The species name is derived from the word “ Ashoka ” in Devanagari, named after the great Indian emperor Ashok, also known as Ashoka the Great, who ruled almost all the Indian subcontinent from 269 BC to 232 BC. His name "aŠoka" means "painless, without sorrow" in Sanskrit. Distribution records. Reunion . Comments. This species exhibits strong similarities with A. longistylus de Saeger, 1944. They differ by minor structural details, but mainly by the characteristic shape of the tergum 2: in A. longistylus , the anterior margin is regularly rounded, without the median point. The three type specimens were collected in the Mare Longue forest. A supplementary female, collected in another humid primary forest, exhibits a very similar habitus though its mesonotum is entirely polished and virtually impunctate. It was therefore not included as a paratype , but before more material is collected we preferred to considered it as an extreme variation of D. ashoka Rousse , sp.nov.
