A new species of the “apacheanus” group of genus Pseudouroctonus from western Texas (Scorpiones: Vaejovidae)

By Richard Ayrey and Michael E. Soleglad
Euscorpius, 2017

A new species of the “apaceanus” group of genus Pseudouroctonus is described from western Texas, USA, Pseudouroctonus brysoni, sp. nov. This new species is closely related to P. apacheanus (Gertsch et Soleglad, 1972) and two other species recently described from southern Arizona. A combination of morphological differences in the hemispermatophore, the mating plug, and several morphometric-based characters are identified as diagnostic.
