9. Daphnia (Ctenodaphnia) psittacea wierzejskii Richard, 1896 View in CoL

Daphnia atkinsoni Baird View in CoL in Wierzejski 1895, p. 181, Pl. 2: fig. 1.

Daphnia psittacea var. wierzejskii Richard 1896a, p. 212 View in CoL –213.

Type locality. Not indicated accurately, the species described based on samples from a series of localities in Germany, Austria and England .

Richard's specimens. Unknown.

The only sample from any of the listed European countries is DGF 958. However, this sample is from Borkum Island, Germany. Richard (1898a) refers to this sample but does not list any taxa from it.

Comments. Richard (1896a) established this name by referring to Wierzejski's (1895) description of " D. atiknsoni ". According to Flössner (1972) Wierzejski's specimens were D. similis Claus, 1876 , so D. psittacea wierzejskii is a junior synonym of D. similis . The subsequently named Daphnia wierzejskii Lity ṅski, 1913 is a junior homonym of the Richard's taxon.
