The following dataset presents all of the specimen records included in the data paper titled: The stoneflies of Arkansas: a preliminary species checklist using museum specimen data. This paper is published in Biodiversity Data Journal. This dataset combines specimen record data from Illinois Natural History Survey Insect Collection, Canadian National Collection of Insects, Western Kentucky University, and several other institutional, personal, and literature records. The data includes specimens to their lowest possible taxonomic rank based on identification and determination. The data includes geo-references for all specimens if possible. Some records lacked precise locality information or were only designated to county level geographic area. This data file will be available for download from Global Biodiversity Information Facility (GBIF). This data file contains a total of 3561 records, structured in 77 columns of data in DwCA format. These data were gathered from April 2024-August 2024. Many specimens used in this work were previously digitized and geo-referenced for a project that was supported by the United States National Science Foundation: CSBR: Natural History: Securing Alcohol Types and Donated Alcohol Specimens at the INHS Insect Collection NSF DBI: CSBR 14-58285.
