Abstract Genital morphology, a cornerstone in taxonomy that predates Linnaeus’s Systema Naturae, is vital for species delimitation. However, the widely accepted paradigm genitalia are taxonomically informative lacks robust testing between closely related species, and supporting evidence often limited to taxonomic literature which assumed priori be species-specific. The cosmopolitan ant genus Nylanderia Emery includes 123 described with most Neotropics still undescribed. Workers morphologically cryptic, males rare collections but required morphological Using Ultraconserved Elements (UCEs) from 236 samples, including 53 Neotropical we reconstructed phylogenetic framework compare (gonopods) of collected alongside workers.
