A population of the greenside darter, Etheostoma blennioides Rafinesque, is recorded for the first time from the Susquehanna River drainage. Meristics are significantly different from populations in the adjacent Allegheny and upper Genesee drainages for dorsal rays and least caudal peduncle scales. Taxonomic comparison places it in the subspecies E. b. blennioides. The population is believed to have entered the Susquehanna drainage via stream capture from the Allegheny. Its presence until now has been undetected because emphasis on taxonomic-distributional research has centered in other geographic areas.
