ABSTRACT: The holomorphology of the eastern Nearctic stonefly genus Remenus Ricker is reviewed using scanning electron microscopy, color photomicrographs and variation in the barcode region of the mitochondrial DNA Cytochrome Oxidase c Subunit I (COI) gene. Examination of all life stages has resulted in new comparative descriptions and a new key to adults. Remenus daniellae Verdone and Kondratieff, sp. n. is described from Great Smoky Mountains National Park, North Carolina and Tennessee, U.S.A. The new species is the fourth species to be included in the genus Remenus and is differentiated from R. bilobatus (Needham & Claassen, 1925), R. duffieldi Nelson & Kondratieff, 1995, and R. kirchneri Kondratieff & Nelson, 1995 by the short clavate epiproct with palmate hair-like spinulae. Larvae can tentatively be separated into two groups based on basal cercal setal length: (1) variable length setae, R. bilobatus and R. daniellae sp. n., and (2) short setae, R. duffieldi and R. kirchneri. With the application of known distributions, larvae of R. kirchneri and R. duffieldi may be distinguished from R. bilobatus and R. daniellae sp. n. However, sympatry and range overlap precludes the use of this character in distinguishing R. bilobatus and R. daniellae sp. n. Ova of the four species apparently lack distinguishing characteristics and thus are not separable at this time. Distribution maps, biological notes, and a neighbor-joining tree based on COI DNA barcodes are also presented.
