Phylogeny and Classification of the Superfamily Scorpionoidea Latreille 1802 (Chelicerata, Scorpiones): An Exemplar Approach
TLDR
A re‐investigation of scorpionoid phylogeny is presented here, based on 115 morphological characters and 71 exemplar species, and revisions are proposed to the existing suprageneric classification of the Scorpionoidea, including new diagnoses, new descriptions, and an illustrated key to the families and subfamilies.
Species or supraspecific taxa as terminals in cladistic analysis? Groundplans versus exemplars revisited.
TLDR
Approaches for overcoming the constraint on the number of taxa included in an analysis differ in the use of species versus supraspeciŽc taxa as terminal entities, which is intimately related to the problem of analyzing large data sets.
Comment on "Identifying spiders through DNA barcodes"
TLDR
To promote the utility of DNA barcoding as a global identification system, these authors must demonstrate that their approach works for distinguishing all the members of a speciose clade, wherever in the world they occur.
The spider tree of life: phylogeny of Araneae based on target‐gene analyses from an extensive taxon sampling
We present a phylogenetic analysis of spiders using a dataset of 932 spider species, representing 115 families (only the family Synaphridae is unrepresented), 700 known genera, and additional
Cheliceral Morphology in Solifugae (Arachnida): Primary Homology, Terminology, and Character Survey
TLDR
The revised terminology, based on hypotheses of primary homology, will facilitate solifuge revisionary systematics and provide a stronger basis for reconstructing phylogenetic relationships within the order Solifugae and testing the phylogenetic position of the order within Chelicerata.
Scorpion higher phylogeny and classification, taxonomic anarchy, and standards for peer review in online publishing
TLDR
Pending the outcome of a rigorous phylogenetic analysis, published according to acceptable standards of scholarship in a peer‐reviewed journal, the suprageneric classification of Scorpiones is reinstated and all changes to the classification proposed by Soleglad, Fet and colleagues since 2001 are rejected.
Wolbachia Are Present in Southern African Scorpions and Cluster with Supergroup F
TLDR
Phylogenetic analyses indicate clustering in the supergroup F and a high genetic relatedness among all scorpion strains as a result of a potential transmission within the host genus, and an older radiation of F-strains with respect to A and B-str strains, followed by limited horizontal transmission across host genera and reduced genetic flux among strains.
Systematics and biogeography of the family Scorpionidae (Chelicerata : Scorpiones), with a discussion on phylogenetic methods
TLDR
This reconstruction identifies Opistophthalmus as the basal lineage of the Scorpionidae, rather than the sister-group of Scorpio, as well as demonstrating relationships among the scorpionid genera as follows.
DNA Isolation Procedures
TLDR
Several of the preparations that have been used successfully in the authors' laboratories are presented and a few “classical” procedures that are “tried and true” and nearly always work are presented.
