Pancrustacean phylogeny: hexapods are terrestrial crustaceans and maxillopods are not monophyletic

Recent molecular analyses indicate that crustaceans and hexapods form a clade (Pancrustacea or Tetraconata), but relationships among its constituent lineages, including monophyly of crustaceans, are controversial. [] Key Result Our phylogenetic analysis of three protein–coding nuclear genes from 62 arthropods and lobopods (Onychophora and Tardigrada) demonstrates that Hexapoda is most closely related to the crustaceans Branchiopoda (fairy shrimp, water fleas, etc.) and Cephalocarida + Remipedia, thereby…

Arthropod molecular divergence times and the Cambrian origin of pentastomids
- Biology
- 2010
Bayesian phylogenetic and relaxed-clock analyses of molecular data help reconcile apparently contradictory views: a pentastomid-branchiuran grouping is recovered, but this clade is the sister group to other Tetraconata, whereas all other crustaceans form a monophyletic group that is sister to hexapods.
Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha

This is the first study to include all hexapod orders in a phylogenetic analysis using multiple nuclear protein-coding genes to investigate the phylogeny of Hexapoda, with an emphasis on Entognatha, and shows that Protura is the sister lineage to all other hexapods and that DiplURA or Diplura + Collembola is closely related to Ectognatha.

This is the first time that a sister group relationship of Remipedia and Hexapoda has been inferred using a comprehensive phylogenomic data set that is based on EST data, and shows that selecting data subsets with increased overall signal can help to identify and prevent artifacts in phylogenetic analyses.

Mapping key crustacean tagmosis patterns and developmental characters across the revised phylogeny suggests that the ancestral pancrustacean was relatively short-bodied, with extreme body elongation and anamorphic development emerging later in pancrustACEan evolution.

The analysis recovered a monophyletic Thysanura sensu lato (Archaeognatha + Zygentoma) as the sister group to Pterygota, a conclusion that is consistent with precladistic notions of hexapod systematics but conflicts with current understanding of morphological evolution.
