The monophyly of Copepoda as a whole (i.e. including Platycopioida) is demonstrated for the first time using molecular data (18S rRNA gene). Within Pan-Crustacea the monophyletic Copepoda is the sister-group of a clade comprising Thecostraca+Tantulocarida and Malacostraca. Maxillopoda is rejected as it is a non-natural, polyphyletic group.
Phylogenetic trees generated by bayesian and maximum likelihood analyses supported the monophyly of the four major subgroups of Copepoda, the Progymnoplea Lang, 1948 (= Platycopioida), the Neocopepoda Huys and Boxshall, 1991, the Gymnoplea, Giesbrecht, 1892 (= Calanoida) and the Podoplea Giesbrecht, 1892. The Progymnoplea is the most basal taxon within Copepoda and sister-group to Neocopepoda. Molecular trees supported the monophyly of only seven copepod orders: Platycopioida, Calanoida, Misophrioida, Monstrilloida, Siphonostomatoida, Gelyelloida and Mormonilloida. Misophrioida (=Propodoplea Lang, 1948) is the most basal Podoplean order. In contrast to previous phylogenetic hypotheses based on morphology, the order Cyclopoida is shown to be paraphyletic, enclosing Poecilostomatoida as a monophyletic derived inner clade. We propose the rejection of Poecilostomatoida as valid order of copepods and suggest referring to this clade as poecilostomes. The marine family Schminkepinellidae Martinez Arbizu 2006 is the sister-group of poecilostomes. Within Harpacticoida, both suborders Polyarthra Lang, 1944 and Oligoarthra Lang, 1944 are monophyletic, but not sister groups. The Polyarthra (families Canuellidae Lang, 1944 and Longipediidae Sars, 1903) clustered basal to a complex of the four remaining orders, suggesting its removal from the Harpacticoida as a separate order which we name Polyarthroida herein. We propose to maintain the name Harpacticoda to refer to the former Oligoarthra only. Gelyelloida is the sister-group of a clade comprising Harpacticoida (=Oligoarthra) + Cyclopoida (including poecilostomes). Monstrilloida is the sister-group of Siphonostomatoida and not a derived clade within the later order as suggested elsewhere.
The taxa Cyclopoida, Harpacticoida and Cyclopinidae are redefined, while Polyarthroida, Smirnovipinidae fam. nov. and Cyclopicinidae fam. nov are proposed as new taxa.

You have reached this page using a special URL that is intended to be used
by journal editors and reviewers or referees of a paper that is under
consideration for publication. This URL gives you access to the submitted
data and metadata associated with analyses and results presented in the
paper under review. Please carefully examine the data paying special
attention to the following:
The citation data (authors, year, citation, abstract) should be
complete, except for information that is not yet known (e.g. volume or
page numbers).
Verify that nexus files are error-free and executable by software
programs (e.g. PAUP, Mesquite, MacClade, etc). Please make sure that the
taxon labels for trees are identical, or a subset of, the taxon labels in
data matrices connected by way of an analysis. If taxon labels in trees do
not match with taxon labels in associated data matrices, the data will not
be useful to the scientific community.
Verify that data are not missing and that opportunities to supply
valuable metadata are not overlooked. For example, TreeBASE can store
Genbank accession numbers, museum voucher IDs, latitude and longitudes for
specimen localities, character names and character state names for
morphological data, etc. Including these metadata are sometimes overlooked
by submitting authors, yet sharing this metadata is extremely valuable to
the scientific community. Please use your power as a reviewer to encourage
the sharing of richly-annotated metadata.
Verify that analyses are not missing and that, where possible, analysis
entries include software commands (e.g. the contents of a PAUP block or
MrBayes block) so that analyses can be replicated easily (e.g. commands
that describe substitution models, data partitions, and heuristic search
parameters).
Verify that taxon labels are mapped against TreeBASE's taxonomic
dictionary. Data in TreeBASE can only be found using a taxon name search if
the taxon labels are properly mapped.
By clicking the 'OK' button below, you agree to keep these data
confidential; you agree not to retain these data after completing your report
to the journal editor; you agree not to use these data or knowledge of these
data for the purposes of your research until and unless the paper under
review has been published and the data have been made available to the
general public; you agree to keep the URL confidential.
