(holotype i: Nghe Tinh prov., W of Rao Qua, tributary of An Bun R„ l-VII-1990; deposited at RMNH, Leiden) appears closely related to R. drusilla Needham, which is here redescribed. Bayadera vietnamensis sp.n. (holotype <J: Nghe Tinh prov., Doi Khe Lao, 11/12-VII-1990; deposited at RMNH, Leiden) is intermediate between B. kali Cowley and Schmidtiphaea schmidi Asahina.
