Phylogenomic Resolution of Paleozoic Divergences in Harvestmen (Arachnida, Opiliones) via Analysis of Next-Generation Transcriptome Data
The first phylogenomics analysis for harvestmen is presented, derived from comparative RNA-Seq data for eight species representing all suborders, and overwhelmingly support the “classical” hypothesis of Opiliones relationships, including the higher-level clades Palpatores and Phalangida.
A taxonomic catalogue of the Dyspnoi Hansen and Sørensen, 1904 (Arachnida: Opiliones).
The included catalogue represents the first comprehensive species and synonymy listing since Roewer (1923) and summarises all taxonomic changes to date and attempts to be a sound basis against the exponential growing number of online errors.
An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)
A hitherto unidentified species of the genus Leiobunum C. L. Koch, 1839, has rapidly invaded central and western Europe and mainly inhabits walls of buildings and rocky environments.
Chemosystematics in the Opiliones (Arachnida): a comment on the evolutionary history of alkylphenols and benzoquinones in the scent gland secretions of Laniatores
Large prosomal scent glands constitute a major synapomorphic character of the arachnid order Opiliones. These glands produce a variety of chemicals very specific to opilionid taxa of different
Hidden Mediterranean diversity: assessing species taxa by molecular phylogeny within the opilionid family Trogulidae (Arachnida, Opiliones).
This is the first comprehensive study to evaluate the relationships between the western palearctic harvestman families Dicranolasmatidae, Trogulidae and Nemastomatidae with focus on the phylogeny and
The evolution of pedipalps and glandular hairs as predatory devices in harvestmen (Arachnida, Opiliones)
It is found that glandular setae are synapomorphic for and widespread in the Palpatores clade (Eupnoi plus Dyspnoi).
Molecular phylogeny of the spider family Sparassidae with focus on the genus Eusparassus and notes on the RTA-clade and 'Laterigradae'.
The phylogeny of the spider family Sparassidae is comprehensively investigated using four molecular markers and the dufouri-, walckenaeri- and doriae-group were confirmed as monophyletic with the two latter groups more closely related.
Molecular phylogeny of the harvestmen genus Sabacon (Arachnida: Opiliones: Dyspnoi) reveals multiple Eocene-Oligocene intercontinental dispersal events in the Holarctic.
Morphological variation supports the divergent genetic clades observed in Sabacon, and suggests that a taxonomic revision may be warranted, as well as nearly simultaneous intercontinental dispersal coincident with the Eocene-Oligocene transition.
Molecular phylogeny, biogeographic history, and evolution of cave-dwelling taxa in the European harvestman genus Ischyropsalis (Opiliones: Dyspnoi)
An algorithmic VIP analysis of historical biogeographic patterns for Ischyropsalis species revealed patterns consistent with a vicariance-dominated history, and molecular phylogenetic data suggest that cave-dwelling species have evolved multiple times independently.
Phylogenetic relationships of the spider family Psechridae inferred from molecular data, with comments on the Lycosoidea (Arachnida : Araneae)
Investigation of the relative phylogenetic position of the spider genera Psechrus Thorell and Fecenia Simon using molecular data of the nuclear 28S rRNA gene and the mitochondrial cytochrome c oxidase subunit I gene indicated no support for a monophyletic family Psechridae.
