New distributional records for ants and the evaluation of ant species richness and endemism patterns in Mexico
Ants (Formicidae) in Mexico have been usually undersampled despite their ecological significance and their utility as service providers and bioindicators. This study estimates the species richness and the narrow endemic species number of ants across Mexico. It also documents the presence of one species newly recorded in Mexico and 19 new state-based records of 14 species from central and north Mexico. No surveys have been performed in most of the localities where we report those records, suggesting the need of a higher sampling effort in the country.We present an ant species richness estimation in a grid of 0.5 degrees in Mexico and a narrow endemic ant species estimation. Stenamma schmitii is reported for the first time from Mexico. Additionally, the new state-based records of Azteca velox, Dorymyrmex insanus, Camponotus coruscus, Camponotus striatus, Formica propatula, Lasius latipes, Neivamyrmex melanocephalus, Neivamyrmex rugulosus, Syscia augustae, Atta texana, Cephalotes scutulatus, Crematogaster crinosa and Temnothorax andrei are reported.
