   Collembola, commonly known as springtails, are important detritivores, abundant in leaf litter and soil globally. Springtails are wingless hexapods with many North American species having wide distributions ranging from as far as Alaska to Mexico. Here, we analyze the occurrence and intraspecific diversity of springtails with a globular body shape (Symphypleona and Neelipleona), in southern high Appalachia, a significant biodiversity hotspot. The peaks of high Appalachia represent ‘sky islands’ due to their physical isolation, and they host numerous endemic species in other taxa. We surveyed globular Collembola through COI metabarcoding, assessing geographic and genetic diversity across localities and species. Intraspecific diversity in globular Collembola was extremely high, suggesting that considerable cryptic speciation has occurred. While we were able to associate morphospecies with described species in most of the major families in the region (Dicyrtomidae, Katiannidae, Sminthuridae, and Sminthurididae), other families (Neelidae, and Arrhopalitidae) are in more pressing need of taxonomic revision before species identities can be confirmed. Due to poor representation in databases, and high intraspecific variability, no identifications were accomplished through comparison with available DNA barcodes.

5. A New, Flightless Species of Medon (Coleoptera: Staphylinidae: Paederinae) from High Appalachia, with Intraspecific Phylogeographic Analysis and Description of its Associated Larva

   Medon icarus Caterino, new species (Staphylinidae: Paederinae) is described, restricted largely to the highest elevations of the southern Appalachian Mountains, USA. This flightless species occurs across several high ranges in the region, and analysis of COI sequences from known populations reveals deep genetic divergences among them. Insufficient morphological differentiation has been observed to subdivide them, but the possibility remains that this represents a cryptic species complex, with from 5–12 genetically but otherwise indistinguishable members. This is the only member of this mainly western Nearctic and Palearctic genus in the southeastern US, though it appears to be closely related to the northeastern winged species Medon americanus Casey. Description of DNA-associated larval specimens, along with adult morphological and molecular information, will help determine its position among global Medonina diversity.
