ABSTRACT Aim In this study, we sought to understand how the Linnean shortfall (i.e., lack of knowledge about species taxonomy) interacts with Darwinian phylogenetic relationships among species), which potentially jeopardises geographical patterns in estimates speciation rates. Location New World. Taxon Coralsnakes (Serpentes: Elapidae). Methods We created an index taxonomic uncertainty (ITU) that measures likelihood current being split after undergoing future revisions. The ITU was used simulations where higher had a having their branches split, generating new hypothetical along geographic ranges. estimated rates before and taxonomically uncertain species. Results found high number coralsnake display substantial uncertainty, positively correlated latitude species' range centroid. based on currently available data have weak relationship latitude. However, incorporating into phylogeny, detect positive correlation between rate Main Conclusions observed change following incorporation highlights such can undermine empirical evaluation rates, revealing interaction latitudinal gradient diversity gradient. Given changes alter recognised as valid over time, our study need incorporate macroecological macroevolutionary studies, enhancing robustness inferred from these data.
