The presence of a strong subaculear spine, along with other characters, places the new species within Wernerius, an incredibly rare genus that until now consisted of only two species. Wernerius inyoensissp. n. can be most easily distinguished from the other members of the genus by smaller adult size, femur and pedi...

Pseudouroctonus peccatum, a new scorpion from the Spring Mountains near “Sin City,” Nevada (Scorpiones, Vaejovidae)

A new scorpion species is described from the Spring Mountain Range near Las Vegas, Nevada. The new species appears to be geographically isolated from other closely related species of Uroctonites Williams & Savaryand Pseudouroctonus Stahnke.

New Analysis of the Genus Pseudouroctonus with the Description of Two New Species (Scorpiones: Vaejovidae)

Further observations on scorpion genera Hadrurus and Hoffmannihadrurus (Scorpiones, Caraboctonidae)

It is demonstrated that the southern populations of this species have a larger number of accessory trichobothria (neobothriotaxy) than the northern populations, numbers exceeding the maximum currently recorded for the genus. Examination of carapace and chela coloration and its patterns show a close aff...
