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

description: 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 fauna
 by nearly five-fold. Nine new species are described, Serranillus
 monadnock sp. n., Anillinus castaneus sp. n., Anillinus choestoea sp. n.,
 Anillinus dentatus sp. n., Anillinus jancae sp. n., Anillinus mica sp. n.,
 Anillinus micamicus sp. n., Anillinus seneca sp. n., and Anillinus
 simplexsp. n. Several species are newly reported, bringing the total to 20
 described species representing seven species groups. Two endemic groups
 inhabit deep clay soils in the Piedmont and possess unique male sexual
 characters. The Anillini are a unique component of Nearctic biodiversity,
 with great potential as a model system for studies of biogeography,
 secondary male sexual modification, and endogean adaptations.
description: 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.

 [https://doi.org/10.5061/dryad.g79cnp5z3](https://doi.org/10.5061/dryad.g79cnp5z3) 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 a consensus tree from 500 standard bootstrap replicates. Nine sets of 500 bootstrap trees are available to display a consensus of. To toggle between them, use the Tree menu and select "Tree&gt; Tree Block (for Consensus Tree)&gt;" and then select the block of trees from the gene of interest.  Eight tabs of aligned DNA sequences, one for each of the loci sampled.  The second NEXUS file, 'Anillini_Core_6gene.nex' displays the same 11 tabs, with the addition of a 12th tab that displays the DNA sequences of the concatenated matrix. This file contains a single maximum likelihood tree and a single block of 500 bootstrap trees.
