Female is slightly larger than male, abdomen blackish brown, lateral margins yellow, or abdomen yellow, apex slightly brownish (see Fujita and Machida 2014).

To date, this is the only Eucorydia species recorded in Japan. However, Sakamaki and Tsuda (2006) also recorded one unknown species from Uji Island. That species superficially resembles the purpuralis population of E. dasytoides but whether it is a new species is still undetermined.

Japan: Ishigaki Island and Iriomoto Island.
