In the foothills of the Sierra Nevada in northeastern California Warren Savary and Rob Bryson uncovered species in the genus Pseudouroctonus. A new species of vaejovid scorpion from northern California, Pseudouroctonus maidu sp. n., is named and described (such was reported by journal Zookeys). 
This new species appears to be most similar to Pseudouroctonus iviei and Pseudouroctonus glimmei. It represents the third species of Pseudouroctonus in California, all endemic to the state, and only the fourth new species of scorpion to be described from California in the past twenty years.
Savary is a field associate of the California Academy of Sciences and has been studyng the scorpions of California since the 1970s. Bryson is a researcher at the University of Washington. The authors have started using DNA to help better understand scorpion diversity. Savary and Bryson t think that there are other new species of scorpions in California.
