Abstract
This paper reports the first records of Cercopagis pengoi in the Mississippi River Basin, Illinois, USA. In 2017, a total of 11 C. pengoi were collected from two different locations during zooplankton sampling in the Illinois Waterway. One location was in the Chicago Sanitary and Ship Canal and the second location was in the Calumet-Sag Channel, approximately eight and 35 river kilometers from Lake Michigan, respectively. In 2021, eight additional individuals were encountered in ichthyoplankton samples collected in the Chicago Sanitary and Ship Canal, three river kilometers upstream of the 2017 capture location. The extent and density of C. pengoi within the Illinois Waterway is currently unknown; therefore, additional sampling is warranted to better understand their distribution and abundance to facilitate an assessment of the risks of spread to other connected waterways.
