Untangling the ant claws: The army ant (Formicidae: Dorylinae) Labidus mars is a Neivamyrmex

The New World army ants (Hymenoptera: Formicidae) comprise the five genera of the Eciton species group, and together they are important keystone predators in tropical and subtropical environments. Generic boundaries in the group have been considered solid and stable for nearly 100 years. Workers of the widespread and diverse genus Neivamyrmex are readily separable from the other four genera by lacking a subapical tooth on the tarsal claw, while males can be separated with genitalic characters. The genus Labidus is also widespread and is often abundant, with several species that are conspicuous surface foragers. The least known species of Labidus is L. mars, the workers of which have the tarsal tooth but otherwise share many traits with some Neivamyrmex, being completely eyeless and subterranean. This led us to question its generic placement. Here, we used ultraconserved element (UCE) phylogenomics to show that Labidus mars belongs to the genus Neivamyrmex. All phylogenies, inferred..., Here we have deposited contigs representing UCE loci, unfiltered UCE alignments, the concatenated UCE matrix, tree files, and additional data analysis files (partitioning schemes and log files). All new sequence data have been deposited in the NCBI Sequence Read Archive under BioProject#PRJNA1158819. The methods used to generate these data are described below and in the article.
Molecular Taxon Sampling: 
UCE sequence data were newly generated for 12 specimens and combined with published data available from the Dryad repository referenced in Borowiec (2019) for 3 specimens (Table 1). Leptanilloides femoralis Borowiec & Longino 2011 was used as an outgroup following Borowiec (2019). Neivamyrmex specimens were selected using the morphological similarities between Labidus mars and some Neivamyrmex species, using the key to Neivamyrmex species in Watkins (1976) and information from a current project on the evolution of Neivamyrmex (S. Powell & L. Barros, personal communication)..., , # Data from: Untangling the ant claws: The army ant (Formicidae: Dorylinae) *Labidus mars* is a *Neivamyrmex*
