A revision of the subgenus Eurycercus (Teretifrons) Frey, 1975 (Crustacea: Cladocera) in the Holarctic with description of a new species from Russian Arctic
Our study is aimed at a taxonomic revision of the subgenus Eurycercus (Teretifrons) Frey, 1975 (Crustacea: Cladocera: Eurycercidae) in the Holarctic based on the morphology of parthenogenetic females. Three species were revealed and described: (1) E. glacialis Lilljeborg, 1887 which is relatively wi...
