  author={W. Shear and W. Schawaller and P. M. Bonamo},
PSEUDOSCORPIONS (Class Arachnida; Order Pseudoscor-piones) represent a diverse and abundant group of small predatory arthropods1–4. Approximately 3,000 living species occupy habitats ranging from sea level to 5,000 metres elevation. Until now, the fossil record of the group extended back only 35 million years, to the Oligocene, where nearly 30 species, all in extant families, have been described from the Baltic Amber5. Addition pseudoscorpions have been described from the younger Dominican6 and… Expand

The fossil history of pseudoscorpions (Arachnida: Pseudoscorpiones)
Abstract. Pseudoscorpions, given their resemblance to scorpions, have attracted human attention since the time of Aristotle, although they are much smaller and lack the sting and elongated tail.Expand
The first fossils of the most basal pseudoscorpion family (Arachnida: Pseudoscorpiones: Pseudotyrannochthoniidae): evidence for major biogeographical shifts in the European paleofauna
Pseudoscorpions belong to the oldest terrestrial lineages with origins in the Devonian (ca. 385 Ma) but their fossil record is extremely sparse and little is known about their diversification overExpand
Cheliferoid pseudoscorpions (Arachnida, Chelonethi) from the Lower Cretaceous of France
A new genus is described from the Lower Cretaceous amber of Archingeay (Charente-Maritime, France), characterized by having gaping chelal fingers, elongate tarsal setae on leg I and the basal position of the tactile seta on the tarsus of legs III and IV. Expand
Ecological and evolutionary pathways of social behavior in Pseudoscorpions (Arachnida: Pseudoscorpiones)
It is discussed that the extended parental care, division of labor, cooperative breeding and feeding, and the tolerance among members dividing the same share could be considered enough to characterize a true social life, same in invertebrates. Expand
Phylogenomic interrogation resolves the backbone of the Pseudoscorpiones Tree of Life.
Pseudoscorpiones, with nearly 3,700 described species, are an ancient and globally distributed group of arachnids, with a fossil record dating back to the Middle Devonian. Previous attempts toExpand
Arthropod Phoresy Involving Pseudoscorpions in the Past and Present
The present work brings up to date phoretic associations between pseudoscorpions and different arthropods and discusses the long-standing controversy over whether this behavior is basically a predatory response or adapted solely for dispersal. Expand
First molecular phylogeny of the major clades of Pseudoscorpiones (Arthropoda: Chelicerata).
The phylogenetic pattern suggests that venom glands evolved just once within this order of arachnids, and Feaelloidea constituted the sister group to all other pseudoscorpions; Chthonioidea is the sistergroup to the remaining families, which constitute the group Iocheirata sensu Harvey--a clade including pseudosCorpions with venom glands within the pedipalpal fingers.

An annotated checklist and a family key to the pseudoscorpion fauna (Arachnida: Pseudoscorpiones) of Sri Lanka.
An island-wide survey of pseudoscorpions using a range of collection methods to sample a diverse set of habitats around the country produced 32 species, four of which might be new to science, belonging to 25 genera. Expand
CHAPTER 7 Fossil Taxa and Relationships of Chelicerates
Chelicerata belong in Arachnomorpha and comprise Xiphosura, Eurypterida, and Arachnida. Pycnogonida, Aglaspidida, Chasmataspida, and a number of merostomoid taxa, e.g., Sanctacaris, are regarded asExpand
A new chernetid pseudoscorpion from the Miocene Chiapas – Amber Lagerstätte, Mexico
Mayachernes maatiatus, a new genus and species of pseudoscorpion of the family Chernetidae (Arachnida: Pseudoscorpionida), is described from the Miocene Chiapas – Amber Lagerstatte, south of Mexico.Expand
