Each of these four species was found at have a striato-reticulated metasoma; within the group of Nearctic species previously mis-classified into Andricus ‘sensu lato’ , this metasomal sculpturing is diagnostic for the genus Striatoandricus . In addition, they share the extra characters noted above that allow diagnosis of Striatoandricus from Druon , and the characters mentioned in the genus-level key within Melika et al . 2021b that distinguish Striatoandricus from other related genera. Thus, we herein transfer these four species to Striatoandricus . A key to Striatoandricus species was given in Cuesta-Porta et al . (2020) ; herein diagnostic differences are given in a “Diagnosis” to each of the four transferred species.
