[1] Photographs of a new unknown scorpion species were uploaded to the citizen science platform iNaturalist in 2013.

They were assisted by Lauren Esposito of the California Academy of Sciences and acted as first authors when describing the new scorpions in 2022.

[3][4] The specific epithet conclusus, Latin for "confined", was given to this species based upon its very limited known range.

Though no formal assessments have taken place yet, P. conclusus is only known to exist in a strip of unprotected land less than 2 kilometers in length around the playa Koehn Lake.

[5] Given the small distribution, this species is extremely vulnerable to extinction via infrastructure or residential development projects.
