Eurycercus longirostris
Eurycercus longirostris is a Holarctic cladoceran crustacean first described by Hann in 1982. A 2011 taxonomic revision synonymized E. vernalis with E. longirostris due to lack of morphological and genetic justification for their separation. The species has a broader distributional range than previously recognized and belongs to the subgenus Eurycercus (Eurycercus). As a member of the Eurycercidae family, it shares characteristics with other chydorid-like cladocerans including a rounded carapace and specialized feeding appendages.
Macrothricidae
Macrothricidae is a family of small freshwater crustaceans in the order Diplostraca (formerly Anomopoda), commonly known as water fleas. The family comprises approximately 17 genera and at least 80 described species. Macrothricids exhibit diverse ecological specializations and feeding mechanisms, with many species inhabiting littoral zones of lakes and ponds. The family remains among the least studied groups of Cladocera, with ongoing taxonomic revisions revealing previously unrecognized species diversity and biogeographic patterns.
