The ordinal level phylogeny of the Arachnida and the suprafamilial level phylogeny of the Opiliones were studied on the basis of a combined analysis of 253 morphological characters, the complete sequence of the 18S rRNA gene, and the D3 region of the 28S rRNA gene. Molecular data were collected for 63 terminal taxa. Morphological data were collected for 35 exemplar taxa of Opiliones, but groundplans were applied to some of the remaining chelicerate groups. Six extinct terminals, including…

Three-dimensional reconstruction and the phylogeny of extinct chelicerate orders

TLDR
X-ray microtomography is used to reconstruct members of two extinct arachnid orders, and a cladistic analysis of the chelicerates is presented to accompany these reconstructions, suggesting that these results are not robust to the addition of novel characters or fossil taxa.

HESPERONEMASTOMA SMILAX, N. SP., A REMARKABLE NEW HARVESTMAN FROM A CAVE IN WEST VIRGINIA, WITH COMMENTS ON OTHER REPORTED CAVE-DWELLING HESPERONEMASTOMA SPECIES (OPILIONES, ISCHYROPSALIDOIDEA, SABACONIDAE)

Hesperonemastoma smilax, n. sp., is a minute, highly troglomorphic harvestman described herein from a single male specimen collected in McClung's Cave, Greenbrier County, West Virginia.

The affinities of mites and ticks : a review

TLDR
Previous hypotheses of mite affinities are reviewed to highlight important character sets which should be included in subsequent phylogenetic analyses, as well as useful areas for future investigations: particularly tagmosis and the nature of the gnathosoma.

The complete mitochondrial genome of the sea spider Achelia bituberculata (Pycnogonida, Ammotheidae): arthropod ground pattern of gene arrangement

TLDR
Maximum likelihood and Bayesian inference trees inferred from the amino acid sequences of mitochondrial protein-coding genes consistently indicate that the pycnogonids (A. bituberculata and N. gracile) may be closely related to the clade of Acari and Araneae.

A phylogenetic analysis of the arachnid orders based on morphological characters

TLDR
Results suggest that attempts to resolve specific nodes based on individual characters, lists of similarities, evolutionary scenarios, etc., are problematic, as they ignore broader impacts on homoplasy and analytical effects on non-target nodes.

Pycnogonid affinities : a review

TLDR
Morphologically some characters – the presence of gonopores on the trunk and absence of a labrum, nephridia and intersegmental tendons – support Cormogonida (Euarthropoda excluding pycnogonids), yet even the putative autapomorphy of chelicerae needs to be treated with caution.

The systematics of the south-east Asian genus Fangensis Rambla (Opiliones : Cyphophthalmi : Stylocellidae)

TLDR
The hitherto monotypic opilionid genus Fangensis Rambla is re-evaluated from new material collected in northern, western and southern Thailand and morphological and ribosomal data suggest monophyly of Fangensis, which is in turn divided into two clades, one composed of the three species from northern and western Thailand and the other represented by the species from southern Thailand.

Phylogeny of Opiliones (Arachnida): An Assessment of the "Cyphopalpatores" Concept

TLDR
Analysis of relationships among the major lineages of Opiliones using both genitalic and non-genitalic char- acters reaffirms the observation that a given hypothesis of character evolution can be consistent with several phylogenetic hypotheses and that an empirically robust phylogenetic analysis should include more than one character system.

Arthropod Cladistics: Combined Analysis of Histone H3 and U2 snRNA Sequences and Morphology

TLDR
The most parsimonious trees based on 211 non‐sequence characters (273 apomorphic states) support traditional higher taxa as clades, including Mandibulata, Crustacea, Atelocerata, Myriapoda, and Hexapoda and monophyly of Chelicerata is maintained under a range of transition/transversion and third codon weights.

Fossil Evidence, Terrestrialization and Arachnid Phylogeny

TLDR
This work proposes a synapomorphy for scorpions 1 eurypterids, a postabdomen of five segments as part of an opisthosoma of 13 segments, and considers these to include book lungs, Malpighian tubules, absence of carapace pleural margin, and an anteriorly directed mouth.
