Remarks: We follow Palma (2017: 216) in regarding the populations of Trabeculus hexakon from species of Pterodroma and Puffinus as sensu lato because they have subtle but clear and consistent differences from the populations of Trabeculus hexakon from the type host, Procellaria aequinoctialis , and the other species of Procellaria .

Valparaíso, Masafuera Island, Isla Santa Clara, Isla Guamblin, and Isla Bartolomé are all new locality records for Trabeculus hexakon sensu lato in Chile, based on seven samples from Pterodroma defilippiana , Pterodroma externa , Puffinus creatopus and Puffinus griseus held in MONZ. Yaldad is also a new locality record for this louse in Chile, based on a sample from Puffinus griseus held in NHML ( Shchedrina et al. 2017).
