Recently, there have been several papers concerning the higher taxonomy and phylogeny of scorpions. Soleglad & Fet published a paper in revising the phylogeny of scorpions.

In NovemberPrendini & Wheeler published an extensive paper criticizing in detail many of the changes published on scorpion higher phylogeny and taxonomy in.

In his revision of the genus Scorpiops, Vachon () described three new subgenera, Alloscorpiops, Euscorpiops, and Neoscorpiops, in addition to the nominotypical subgenus Scorpiops.

Alloscorpiops was defined on the basis of an important ‘majorante’ neobothriotaxy with 10–12 ventral trichobothria on the surface of pedipalp chela-hand, whereas the other subgenera presented only four by: 6.

The lack of a reliable phylogeny for scorpions is a major impediment for evolutionary studies of Cited by: In the present note, a remarkable new genus and species belonging to the family Scorpiopidae are described from Saddan Cave, located in Kayin State, Hpa-An, Burma-Myanmar (Fig.

1, Fig. 2, Fig. 3, Fig. 4, Fig. 5).This new scorpion taxon is the fourth species of Scorpiopidae, to be discovered in cave systems and the first one belonging to a new by: 2. The basal branching point in the tree represents the ancestor of the other groups in the tree.

This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right. Adults range in size from cm to 21 cm in length. Some fossil scorpions are thought to have been up to 1 meter in length. All are predatory.

Their prey includes a variety of arthropods and other invertebrates, and the larger species are known to prey on small vertebrates. The scorpion's most notorious feature is its poisonous sting.

Prendini’s research addresses the systematics, biogeography and evolution of scorpions, using a combination of morphological, molecular and distributional data, and diverse analytical tools. Current research on scorpions is focused in three main areas: reconstructing the phylogeny and revising.This article is about the arthropod.
