Relationships among the following taxa were examined based on 18S ribosomal RNA and DNA nucleotide sequences: Branchiopoda (Branchinecta packardi), Ostracoda (two podocopid species), Branchiura (Argulus nobilis), Pentastomida (Porocephalus crotali), Copepoda (Calanus pacificus, Macrocyclops albidus), Thoracica (Balanus eburneus, Calantica villosca), Acrothoracica (Trypetesa lampas), and Decapoda (Procambarus leonensis, Callinectes sapidus). Phylogenetic relationships were inferred by maximum… 
Phylogenetic Study of Cirripedes and Selected Relatives (Thecostraca) Based on 18s Rdna Sequence Analysis
TLDR
It is concluded that the Thecostraca, represented here by the subclasses Ascothoracida and Cirripedia (the latter including the Acrothoracica, Rhizocephala, and Thoracica), is a monophyletic taxon.
Molecular phylogeny of Ostracoda (Crustacea) inferred from 18S ribosomal DNA sequences: implication for its origin and diversification
TLDR
The tree topology and the crustacean fossil record suggest that the lineage of podocopidans and platycopidans should have separately been established already in the Cambrian, although there is no ostracod fossil record in that time period.
Mitochondrial and nuclear rRNA based copepod phylogeny with emphasis on the Euchaetidae (Calanoida)
TLDR
Phylogenetic mapping using the most parsimonious 16S tree suggests that the morphological synapomorphies distinguishing the genus Euchaeta evolved independently twice during the history of the Euchaetidae, and that a bathypelagic, vertically migrating lifestyle characteristic of Paraeuchaeta is an ancestral trait of the family Echaetidae which was lost apomorphically by EuchaETA.
REANALYSIS OF THE RELATIONSHIPS AMONG THE CIRRIPEDIA AND THE ASCOTHORACIDA AND THE PHYLOGENETIC POSITION OF THE FACETOTECTA (MAXILLOPODA: THECOSTRACA) USING 18S rDNA SEQUENCES
TLDR
The morphological hypothesis that the cirripedes form a monophyletic group, with the Acrothoracica as sister group to the Thoracica + Rhizocephala, strongly supports the model of evolution that fits the data best, and maximum parsimony approaches.
Molecular phylogeny of the mud lobsters and mud shrimps (Crustacea : Decapoda : Thalassinidea) using nuclear 18S rDNA and mitochondrial 16S rDNA
TLDR
Maximum-likelihood and Bayesian analyses show equivocal support for the monophyly of the Thalassinidea, but show strong support for division of the infraorder into two major clades.
First observations on the phylogeny of the families Gammaridae, Crangonyctidae, Melitidae, Niphargidae, Megaluropidae and Oedicerotidae (Amphipoda, Crustacea), using small subunit rDNA gene sequences
TLDR
This study examines amphipod phylogeny based on small subunit (18S) rDNA sequence data and discusses the evolution of cephalothoracic apodemes in the light of other phylogenetic hypotheses resulting from molecular data.
Cladistic analysis of the Cirripedia Thoracica
TLDR
A cladistic analysis of the Cirripedia Thoracica using morphological characters and the Acrothoracica and Ascothoracida as outgroups reveals that several key questions in cirripede phylogeny remain unsolved, notably the position of shell-less forms and the transition from `pedunculate' to `sessile' barnacles.
THE SCUTOCOXIFERA TAX. NOV. AND THE INFORMATION CONTENT OF NUCLEAR SSU RDNA SEQUENCES FOR RECONSTRUCTION OF ISOPOD PHYLOGENY (PERACARIDA: ISOPODA)
TLDR
The results of maximum parsimony analyses are congruent with major aspects of earlier hypotheses on isopod phylogeny and a major monophyletic group found in the molecular phylogenies and also supported by distinct morphological characters is named Scutocoxifera tax.
The interrelationships of metazoan parasites: a review of phylum-and higher-level hypotheses from recent morphological and molecular phylogenetic analyses.
TLDR
Phylogeny of seven groups of metazoan parasitic groups is reviewed, based on both morphological and molecular data, and the lack of relevant information about the enigmatic ectoproctan parasite Buddenbrockia is emphasised.

Molecular Phylogeny of Selected Decapod Crustaceans Based on 18S rRNA Nucleotide Sequences
TLDR
Comparisons among species revealed that the nucleotide sequences of the 3 species of Procambarus are virtually identical, differing in only 3 of more than 1,500 nucleotides, and there is sufficient variation for phylogenetic analysis.
New tantulocarid, Stygotantulus stocki, parasitic on harpacticoid copepods, with an analysis of the phylogenetic relationships within the Maxillopoda.
TLDR
A new genus of Tantulocarida, Stygotantulus, is described based on material from an anchialine pool on Lanzarote, Canary Islands, and is distinguished by the presence of 7 abdominal somites in the tantulus larva.
Upper Cambrian stem-lineage crustaceans and their bearing upon the monophyletic origin of Crustacea and the position of Agnostus
TLDR
Three new arthropods in uncompressed condition have been discovered in Upper Cambrian limestone nodules of Vastergotland, Sweden and their morphology provides new insights into the evolutionary path and progressive development of ground plan characteristics along the stem-lineage and gives further support for the monophyletic origin of Crustacea.
Molecular evidence for inclusion of the phylum pentastomida in the crustacea
TLDR
Comparisons of nucleotide sequences of 18s ribosomal RNA from the pentastome Porocephalus crotali, the branchiuran crustacean fish louse Argulus nobilis, and representatives of the Annelida, Chelicerata, Myriapoda, and Insecta support an Argulus/PorocephaZus clade, providing strong support for the proposal that tongue worms are highly modified crustaceans closely related to fish lice.
The Early Radiation and Relationships of the Major Arthropod Groups
TLDR
Cladistic analysis of characters of Cambrian and living representatives (excluding Uniramia) shows that trilobites and chelicerates are relatively advanced compared with "crustaceans," and there are doubts whether the latter constitute a national group.
Molecular phylogeny of the animal kingdom.
TLDR
A rapid sequencing method for ribosomal RNA was applied to the resolution of evolutionary relationships among Metazoa, finding that coelomates radiated rapidly into four groups: chordates, echinoderms, arthropods, and eucoelomate protostomes.

TLDR
Analysis of rate invariant analysis of 18S rRNA sequences indicates that the Metazoa is a monophyletic taxon, and the Annelida-Mollusca lineage is the sister group of an arthropod subgroup.

Homoplasy Excess Ratios: New Indices for Measuring Levels of Homoplasy in Phylogenetic Systematics and a Critique of the Consistency Index
TLDR
Hers is shown to be more appropriate than CI in comparative taxonomic studies that wish to measure the average level of homoplasy in data sets involving different groups of taxa or different characters, and a new index, the Homoplasy excess ratio (HER), is introduced that takes into account the expected increase in overall homoplASY levels with increasing numbers ofTaxa in systematic studies.
