Proechinophthirus fluctus ochotensis Blagoveshtchensky, 1966: 808 , figs 10–12. Zarubina 1986: 374, fig. 196.6. Synonymised by Kim (1971: 286). Type host. Eumetopias jubatus (Schreber, 1776) —Northern sea lion, in error. The type series of P. fluctus originated from a skin held in the Stanford University Zoology Museum. According to Ferris (1934), it is likely that the skin had been misidentified and that it was a northern fur seal ( Callorhinus ursinus ). Type locality. Not given; presumably Alaska, according to Kim (1971: 286). Type specimen/s data. Syntypes Ƥ and nymphs, deposited in EMEC under numbers 57973 and 52227. Other host. Callorhinus ursinus (Linnaeus, 1758) —Northern fur seal. Geographic distribution. North Pacific Ocean and Bearing Sea. Significant references.

(2010: 296, 298, phylogeny). Remarks. Kim (1971: 286) refers to a “ Holotype male” but Ferris (1916b: 368) did not designate a holotype , he only wrote “ Types , a mature male and a mature female” and then a “ paratype ” from another source. Ferris’s statement cannot be taken as designating a holotype ; therefore they are all syntypes . Jellison (1952: 274) reported two Arctic foxes ( Alopex pribilofensis (Merriam 1902)) with Proechinophthirus fluctus originating from northern fur seals, due to the foxes’ habit of feeding on dead seals.
