DNA barcoding utilizing mitochondrial cytochrome c oxidase subunit 1 (CO1) and morphology were used for species delimitation. Molecular analyses and species delimitation included four methods: 1) General Mixed Yule Coalescent model (GMYC), 2)&nbsp;Automatic Barcode Gap Discovery (ABGD), 3) Bayesian Poisson Tree Process (bPTP), and 4)&nbsp;Assemble Species by Automatic Partitioning (ASAP). All molecular methods and morphology were consistent in delimiting and recognizing the new species described herein. The average interspecific genetic distance (<em>p</em>-distance) among analyzed species of <em>Pseudocellus </em>was 11.6%. The species is described based on adult males and females: <em>Pseudocellus giribeti</em> sp.&nbsp;nov. This is the seventh species described from Chiapas, which holds the highest number of ricinuleids species for the country. The total number of described species of <em>Pseudocellus</em> from Mexico increases to 21, having the highest species diversity of known ricinuleids worldwide.</p>}, number={1}, journal={European Journal of Taxonomy}, author={Valdez-Mondragón, Alejandro and Cortez-Roldán, Mayra R.}, year={2021}, month={Oct.}, pages={1–25} }
