Fossil age data and molecular sequences are increasingly combined to establish a
timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically …

Understanding the evolution of Tetraconata or Pancrustacea—the clade that includes
crustaceans and insects—requires a well-resolved hypothesis regarding the relationships …

The Spinicaudata (spiny clam shrimp) are a large group of freshwater, bivalved branchiopod
crustaceans in need of taxonomic revision. Herein, the extant Spinicaudata families and …

The order Calanoida includes some of the most successful planktonic groups in both marine
and freshwater environments. Due to the morphological complexity of the taxonomic …

Spinicaudata (spiny clam shrimp) is a taxon of Branchiopoda occurring since the Devonian
and today it occurs nearly globally in temporary water bodies. We present the most species …

The extant genera of the spinicaudatan clam shrimp family Limnadiidae are revised using
morphological criteria built on previously published molecular analyses. The combined …

Cyclestheria hislopi is thought to be the only extant species of Cyclestherida. It is the sister
taxon of all Cladocera and displays morphological characteristics intermediate of …

The unambiguous delineation and identification of species remain central problems in
systematic and taxonomic studies. Species delineation depends on the data utilized and the …

Clam shrimp (the paraphyletic assemblage of spinicaudatans, laevicaudatans, cyclestherids
and the extinct leaiins) are small, bivalved branchiopod crustaceans that specialize in …

We present the first record of Eocyzicus from Taiwan. Eocyzicus taiwanensis n. sp. can be
distinguished from all other Eocyzicus species by the form of the claspers, the telson and the …
