Description wikipedia

The Illinois chorus frog (Pseudacris illinoensis) is a species of chorus frog that lives in scattered, restricted habitat ecosystems in the states of Arkansas, Illinois, and Missouri. It was published by Smith in 1951. Its life cycle is little known, its isolated populations are increasingly restricted by agricultural drainage, and it is listed as a threatened subspecies. It is often referred to as a subspecies of P. streckeri. Collins recognized it as its own species which was followed by ASW6.0 and Amphibiaweb on the basis of its diagnosability from Pseudacris streckeri and its allopatry. The IUCNredlist 2013.2 has not incorporated this taxonomic split.
