Two individuals of Latrodectus hesperus Chamberlin & Ivie were newly found in munitions storage at military facilities in Daegu, South Korea. A female was first discovered on August 31, 2018, and followed by another female along with three egg sacs on September 20, 2018. These spiders were identified based on morphological characters and DNA barcode sequence analysis. Additional surveys were made around the initial detection site to examine the range and spread of this species, but no additional individuals were found.
