Specimens examined. None.

Comments. The type series of this species is deposited in the Zoological Survey of India Collection but for unexplained reasons is not available for loan (Mukhopadhyay, per. com.). From the description it appears that the species belongs to Chaeridiona , but Basu (1999) does not mention many of the generic characters. Until someone can examine the type, the species is retained in Chaeridiona and is treated as valid.
