Phylogenetic relationships in Opiliones (Arachnida) at the suborder level have greatly stabilized in recent years, largely due to advances in molecular systematics. Nonetheless, identifying morphological characters in the context of well-resolved phylogenies is essential for testing new systematic hypotheses and establishing diagnostic markers. Here, we investigate with SEM a promising character system across Opiliones: the sensilla on the distalmost article of legs I and II. We identified…

Predatory behavior and sensory morphology of the whip spider Charinus asturius (Arachnida: Amblypygi)
TLDR
This study described the sensory morphology of the antenniform leg and the predatory behavior of Charinus asturius Pinto-da-Rocha, Machado and Weygoldt, 2002, a representative of the family Charinidae and reports the presence of most sensilla types described in the better studied Phrynidae and highlights novel aspects such as the morphology ofthe tarsal organ and the reduced number of rod sensilla.

The ecological tale of Gonyleptidae (Arachnida, Opiliones) evolution: phylogeny of a Neotropical lineage of armoured harvestmen using ecological, behavioural and chemical characters
TLDR
This work used the information available in the literature and an intensive search for ecological, behavioural and chemical data to infer the phylogeny of the Gonyleptidae, and obtained five most parsimonious trees and the strict consensus resulted in six collapsed nodes.
A multilocus approach to harvestman (Arachnida: Opiliones) phylogeny with emphasis on biogeography and the systematics of Laniatores
TLDR
Age estimates for the main Opiliones lineages suggest a Carboniferous diversification of Cyphophthalmi, while its sister group, Phalangida, diversified in the Early Devonian, and most major lineages predate the Cretaceous.
The evolutionary and biogeographic history of the armoured harvestmen – Laniatores phylogeny based on ten molecular markers, with the description of two new families of Opiliones (Arachnida)
TLDR
Ancestral range reconstruction of the clade suggests that the ancestral range of Samooidea comprises West Tropical Gondwana (West Africa + Neotropics), whereas that of Zalmoxoidea is exclusively Neotropical.
A stable phylogenomic classification of Travunioidea (Arachnida, Opiliones, Laniatores) based on sequence capture of ultraconserved elements
TLDR
DNA sequences derived from capture of ultraconserved elements (UCEs) are utilized to reconstruct travunioid relationships and a revision of Travunioidea is proposed, now consisting of the Travuniidae, Cladonychiidae, Paranonychidae, and the new family Cryptomastridae Derkarabetian & Hedin, n.
A Paleozoic Stem Group to Mite Harvestmen Revealed through Integration of Phylogenetics and Development
TLDR
The discovery of Tetrophthalmi alters molecular divergence time estimates, supporting Carboniferous rather than Devonian diversification for extant suborders and directly impacting inferences of terrestrialization history and biogeography.
Sandokanid phylogeny based on eight molecular markers--the evolution of a southeast Asian endemic family of Laniatores (Arachnida, Opiliones).
TLDR
The internal phylogeny of the family Sandokanidae, the putative sister group of the other families of the highly diverse infraorder Grassatores, is investigated on the basis of sequence data from eight molecular loci and demonstrates the monophyly of nearly all described genera, corroborating previous morphological observations.
Tarsal Organ Morphology and the Phylogeny of Goblin Spiders (Araneae, Oonopidae), with Notes on Basal Genera
TLDR
Based on a survey of a wide variety of oonopid genera and outgroups, it is hypothesized that new synapomorphies uniting the Oonopidae (minus the South African genus Calculus Purcell, which is transferred to the Orsolobidae) are hypothesized.
A revised dated phylogeny of the arachnid order Opiliones
TLDR
These analyses support basal diversification of Opiliones in the Ordovician-Devonian period, corroborating the inferred ancient origins of this arthropod order, and underscore the importance of diversity discovery—both paleontological and neontological—in evolutionary inference.
Evolutionary and biogeographical history of an ancient and global group of arachnids (Arachnida: Opiliones: Cyphophthalmi) with a new taxonomic arrangement
TLDR
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.
Evolutionary biology of harvestmen (Arachnida, Opiliones).
TLDR
The rapid emergence and utility of Phalangium opilio as a model for evolutionary developmental biology of arthropods serve as demonstrative evidence of a new area of study in Opiliones biology, made possible through transcriptomic data.
