Phylogenetic systematics of the enigmatic genus Horologion Valentine, with description of a new species from Bath County, Virginia (Coleoptera, Carabidae, Trechinae, Horologionini)

# Data from: Phylogenetic systematics of the enigmatic genus Horologion Valentine, with description of a new species from Bath County, Virginia (Coleoptera, Carabidae, Trechinae, Horologionini) This file is intended to be opened in Mesquite (). Contains DNA sequence data from eight genes, sampled from 259 carabid beetles. Matrices of individual genes and a concatenated matrix, as well as all trees resulting from analyses of this data, are included. When opened in Mesquite, it displays six tabs. The "Taxa" tab includes a list of the 259 beetles and their associated voucher codes, as well as GenBank accession numbers for each of the sequences obtained. The "Character matrices" tab is a list of the matrices of DNA sequence data in the file. The user may view each of these by right clicking and selecting "Show". The "Tree blocks" tab includes a list of trees obtained from maximum likelihood analysis of the DNA sequence data in the file. The last on the list is a block of hypothetical tree topologies used to test support of various clades. The last three tabs are tree windows. The one titled "IQ-TREE ML Trees" is a set of all of the Maximum Likelihood trees obtained from each matrix in the dataset, with one tree visible at a time. The user may scroll between these using the arrows in the upper left. The name of the tree, including the abbreviation of the gene, is visible at the bottom of the screen while viewing it. The other two tree windows, titled "Consensus of *IQ-TREE Bootstrap Trees (Matrix: 8gene" and "IQ-TREE UF Bootstrap Trees (Matrix: 8gene.concatenated)" are showing a maximum likelihood consensus tree and Ultrafast Bootstrapping tree, respectively. By default, both are showing these tress from the concatenated 8-gene matrix. The user may view bootstrap trees from other genes by using the Tree menu; for the standard bootstrap consensus window, select "Tree> Tree Block (for Consensus Tree)>" and then select the block of Bootstrap Trees from the gene of interest; for ultrafast bootstrap trees, select "Tree> Tree Block (for Tree Window)" and select the IQ-TREE UF Bootstrap tree from the gene of interest. The DNA sequence data in this file can be exported in a variety of formats and used in virtually any phylogenetic analysis program.
