Rounding up the usual suspects: a standard target‐gene approach for resolving the interfamilial phylogenetic relationships of ecribellate orb‐weaving spiders with a new family‐rank classification…
The orb‐web is ancient, having evolved by the early Jurassic; a single origin of the orb with multiple “losses” is implied by the analyses, and the resulting phylogenetic framework is used to study web evolution in araneoids.
Phylogenomic interrogation resolves the backbone of the Pseudoscorpiones Tree of Life.
Evolutionary and biogeographical history of an ancient and global group of arachnids (Arachnida: Opiliones: Cyphophthalmi) with a new taxonomic arrangement
Analysis of molecular and morphological data allow for a new classification system for an ancient group of arachnids, the harvestman suborder Cyphophthalmi, and resolves the position of many monotypic genera not available for molecular analysis, although it does not place Shearogovea or Ankaratra within any existing family.
Biogeography of the world: a case study from cyphophthalmid Opiliones, a globally distributed group of arachnids
A group of primitive arachnids which originated before the break‐up of Pangaea and currently inhabits all major landmasses with the exception of Antarctica, but lacks the ability to disperse across oceanic barriers is selected.
An illustrated catalogue of the South American species of the cyphophthalmid family Neogoveidae (Arthropoda, Opiliones, Cyphophthalmi) with a report on 37 undescribed species
We provide an illustrated catalog of the cyphophthalmid diversity of the Neotropics, including photographs of the holotypes and paratypes (when available) for all but one described South American…

The inclusion of historical ethanol‐preserved museum specimens in modern sequence capture phylogenomic studies is successfully demonstrated, a high frequency of variant bases at the species and population levels, and from off‐target reads successfully recover multiple loci traditionally sequenced in multilocus studies including mitochondrial loci and nuclear rRNA loci are recovered.
Converging on the orb: denser taxon sampling elucidates spider phylogeny and new analytical methods support repeated evolution of the orb web
Overall, this work provides the most comprehensive spider tree‐of‐life to date using transcriptomic data and uses new methods to explore controversial issues of web evolution, including the origins and multiple losses of the orb web.
Forest refugia in Western and Central Africa as ‘museums’ of Mesozoic biodiversity

The phylogenetic and molecular dating results suggest that Ricinulei diversified in association with the fragmentation of Gondwana, and suggest that refugia may have acted as ‘museums’ conserving ancient diversity rather than as engines generating diversity during successive episodes of climatic fluctuation in Africa.
Molecular phylogenetic analysis of “pirate spiders” (Araneae, Mimetidae) with the description of a new African genus and the first report of maternal care in the family
Phylogenetic analyses based on parsimony, maximum‐likelihood and Bayesian approaches, robustly support monophyly of Mimetidae and a sister‐group relationship to a clade comprising Tetragnathidae + Arkyidae.
The ‘Peripatos’ in Eurogondwana? – Lack of evidence that south-east Asian onychophorans walked through Europe

A molecular phylogenetic analysis of Onychophora is presented that includes previously unsampled and undersampled lineages and is analysed using a series of nested taxon sets designed to increase the amount of information available for particular subclades.
