Hurd 1952 separated Pepsis cerberus Lucas from P elegans Lepeletier Hymenoptera Pompilidae Pepsinae Pepsini based on external morphology and biogeography Vardy 2005 synonymized the familiar and historically well-documented P cerberus and P elegans combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P menechma Lepeletier In doing so Vardy 2005 breached the principle of nomenclatural stability He ignored the prevailing usage and clearly violated articles 23 2 23 3 and 23 9 1 2 of the ICZN 1999 Morphological differences ecological divergence and narrow sympatric geographic distribution of P cerberus and P elegans contradict Vardy 2005 and justify full species status Kurczewski 2023a Furthermore we propose the removal of the two species from the P menechma list of synonyms and recommend full species reinstatement as Pepsis cerberus restored status and Pepsis elegans restored status Pepsis menechma becomes a senior synonym of P elegans Morphometric re-examination and statistical analysis of P cerberus and P elegans structural features strongly support their reinstatement Quantitative measurement of 10 parasitoid-related morphological characteristics of the females revealed the two species differ significantly in frons width head width head length head width vertex length head width vertex length head length flagellomere 1 length flagellomere 1 width forewing length mesosoma width and hind tibial inner spur length hind basitarsus length Pepsis cerberus and P elegans females are structurally and statistically similar in gena-postgena corner radius fore femur width mesosoma width and number of hind tibial serrations ZooBank registation urn lsid zoobank org pub D22EC64F-7C55-4071-9290-4661CA377B24
