Systematics and biogeography of Appalachian Anillini, and a taxonomic review of the species of South Carolina (Coleoptera, Carabidae, Trechinae, Anillini)

In the eastern United States, 74 species of Anillini in two genera have been described, with most belonging to AnillinusCasey. Until now, no systematic framework has existed for this large genus, hampering integrative studies. Using DNA sequences from 98 Nearctic species, we present a well-resolved molecular phylogeny supporting a sound systematic framework. Twenty-one species groups of Anillinus are diagnosed, in part using newly recognized variation in the number of modified male protarsi and the state of the spermathecal duct. We present the first descriptions of Nearctic anilline larvae, which possess none of the synapomorphies of other anilline larvae. Within Anillinus, two major clades are mostly consistent with setation of the right paramere: a “hairy clade” with more than four setae, and a “quadrisetose clade.” Throughout the phylogeny, microhabitat use varies within each clade, and several endogean lineages are phylogenetically isolated. Our work increases the South Carolina fa..., This dataset, consisting of two Nexus files, consists of DNA sequences that were obtained by Sanger sequencing by Psomagen, and trees resulting from Maximum likelihood analyses performed with IQ-TREE. Forward and reverse reads were sequenced, and assembled using Geneious. Chromatograms were studied in Geneious, and ambiguity codes were applied where double peaks were apparent. The sequences were trimmed and aligned in the program Mesquite. The Zephyr package in Mesquite was used to orchestrate maximum likelihood analyses using IQ-TREE. , , # Data from: Systematics and biogeography of Appalachian Anillini, and a taxonomic review of the species of South Carolina (Coleoptera, Carabidae, Trechinae, Anillini)

Two NEXUS files containing aligned DNA sequences and phylogenetic trees from the paper \"Systematics and biogeography of Appalachian Anillini, and a taxonomic review of the species of South Carolina (Coleoptera, Carabidae, Trechinae, Anillini)\"

These two files are intended to be opened with Mesquite ([http://mesquiteproject.org](http://mesquiteproject.org)).

When opened, the file \"Anillini_All_singlegene.nex\" displays 11 tabs:

'Taxa': a table of taxa sampled and associated GenBank numbers

'IQ-TREE ML Trees': a window displaying a tree from maximum likelihood analysis using IQ-TREE. Nine trees are available to view, and can be toggled using the arrows in the upper left corner.

'Consensus of IQ-TREE Bootstrap Trees': a window displaying...
