We documented the historical distribution of Pteronotropis hubbsi (Bluehead Shiner) based on a survey of museum records. To compile historical records, we searched 6 online databases and contacted 28 individuals associated with natural history museums, state agencies, and public and private universities. Eleven individuals had records of Bluehead Shiner in their collections. Geographically, the records were from 5 states, which included a disjunct population in Illinois. In the core of the distribution (i.e., 4 states), all collections were in the Red River and 4 major tributary rivers to the Red River. The number of different localities within each of these waterways ranged from 1–17. These records spanned 57 y (1949–2006), with the majority (95%) of records from the 1970s to the 1990s. The number of specimens cataloged per locality ranged from 1 to 144 individuals. All major-tributary drainages had at least 1 collection with more than 25 individuals archived. We argue that this geographic analysis of the historical distribution of Bluehead Shiner illustrates a great need to launch a modern field effort to document the current status of Bluehead Shiner throughout the Red River drainage in Arkansas, Louisiana, Oklahoma, and Texas.
