12. Ceriodaphnia dubia Richard, 1894

Ceriodaphnia dubia Richard 1894b, p. 570 –572, figs 6–8; Sars 1904, p. 631, Pl. 33: figs 2, 2a–b.

Type locality. "Lac Toba" (Richard 1894b), N. Sumatra, Indonesia .

Richard's specimens. Unknown. See discussion of sample DGF 723 under Diaphanosoma modigliani .

Comments. A valid species. Although similar specimens have been reported from many regions of the world, e. g. Europe ( Flössner 1972, 2000; Alonso 1996), Canada, U.S.A., Bolivia, East Africa, Australia ( Berner 1987), the species needs to be revised and specimens from different regions reconciled. The non- Indonesian populations particularly must be checked against specimens from the type locality.
