Kotov, Alexey A. & Gololobova, Maria A., 2005, Types of cladoceran species described by Sven Ekman in the Swedish Museum of Natural History, with redescription of Daphnia cavicervix Ekman, 1900 (Daphniidae, Anomopoda, Cladocera), Journal of Natural History 39 (33), pp. 3059-3074 : 3061-3063

Alona bucobensis var. subantarctica Ekman, 1905

Alona bucobensis var. subantarctica Ekman 1905, p 8 –9.

Alona weinecki Studer, 1878 in Rühe 1914 p 53–55, Figure 18c, d; Frey 1988, p 1400 – 1407, Figures 57–104.

Lectotype: parthenogenetic female, SMNH 3615, selected by Frey (1988). Before Frey’s (1988) revision, there were, according to an old catalogue, three Ekman specimens in the collection of SMNH, mixed in a tube: a single specimen was taken from each of three different localities: locality 7 from the Falklands, and localities 3 and 5 from South Georgia. Frey (1988) recovered only two females, and designated one of them as the lectotype. Paralectotype: parthenogenetic female, SMNH 3616, selected by Frey (1988).

Type locality

Frey (1988) said that ‘‘although the lectotype origin is not certain, it is considered to derive from South Georgia’’, but this thesis seems to be not well justified.

Comments

Ekman’s taxon is now regarded as a junior synonym of Alona weinecki Studer, 1878 . See illustrations, expanded description and comments in the paper of Frey (1988).
