Chilean host: Macronectes giganteus (Gmelin, 1789) .

Other significant references: KÉler (1957a); Timmermann (1965); Clay & Moreby (1967); Pilgrim & Palma (1982: 6); Palma (1996: 197); Price et al. (2003: 205); Page et al. (2004: 641, 649); Hänel & Palma (2007: 113, 126, 129); Palma (2010: 408); Palma (2017).

Remarks: Paraclisis obscura is highly prevalent among the lice parasitic on giant petrels ( Macronectes spp. ) (R.L. Palma pers. observation). The neotype and several neoparatypes of Paraclisis obscura are from “ Chile ”, without specific localities, and held in NHML ( Shchedrina et al. 2017). Coloso is a new locality record for P. obscura in Chile, based on a sample from Macronectes giganteus held in NHML ( Shchedrina et al. 2017). Thompson (1940a: 641) recorded a few specimens of P. obscura from Masatierra Island without host data, citing Diomedea melanophrys as a host “open to doubt”.
