An annotated checklist consisting of 300 species is provided for the mayfly fauna of the southeastern United States [Alabama (139 spp.), Arkansas (118 spp.), Florida (77 spp.), Georgia (155 spp.), Kentucky (135 spp.), Louisiana (61 spp.), Mississippi (59 spp.), North Carolina (207 spp.), South Carolina (185 spp.), Tennessee (167 spp.), Virginia (170 spp.), West Virginia (119 spp.)]. The list is based on previously published and newly published collection data. Some 107 supported state records in the region are also provided based on 92 of the species. The Southeast is the richest region in North America in terms of mayfly biodiversity, but the states of Louisiana and Mississippi remain poorly known. Source

A new species of flat-headed mayflies (Heptageniidae) is described as Maccaffertium wudigeum McCafferty and Lenat, n. sp. The species is based on larvae taken from western North Carolina. It is morphologically most similar to some M. mediopunctatum (McDunnough) larvae, but does not possess any of the distinguishing markings associated with the latter and also differs from it in habitat.

Uktena riparia n. gen., n. sp. has been collected in hyporheic habitats at several sites in North Carolina, southeastern USA. The genus is defined by unusual characters related to reproductive structures, including the formation of encapsulated spermatophores for sperm transfer and large bundles of genital chaetae, both previously unknown in the Lumbriculidae. The simultaneous occurrence of both spermatophores and spermathecae is rare in the microdrile oligochaetes. Uktena spermatophores appear more similar to those reported in leeches than to those in other microdrile oligochaete families. Possible synapomorphies associating Uktena with the genera Kincaidiana and Guestphalinus include a filiform, ringed proboscis, a forward shift of reproductive organs relative to the usual position in the family, and spermathecae in the atrial segment. The new species adds to the already diverse, endemic lumbriculid fauna of the North Carolina Sandhills ecoregion. Copyright © 2015 Magnolia Press. Source

Stenelmis hollandi White and Lenat, a new species of riffle beetle (Elmidae), is described from the Little River drainage of North Carolina, within the Cape Fear River basin. It may be separated from similar species by the male genitalia, small size, distinct single testaceous vitta on each elytron that does not overlap the umbone, distinctly dilated fifth tarsomere, and a mesotibial ridge in males. Additionally, it has yellowish palpi, antennae, and tarsi. A photograph of the adult along with a photograph of the male genitalia serve to illustrate the defining characters. The discovery of this undescribed species further demonstrates the excellent water quality and the variety of habitats within the Little River drainage. Source
