Material examined.

3 males and 3 females (NIBR No. NIBRIV0000887169-NIBRIV0000887174) from Oceanites oceanicus (Kuhl) ( Procellariiformes , Oceanitidae ), Antarctica, King George Island , Barton Peninsula, 62°14'15'S, 58°46'28"W, 9 January 2016, coll. Han Y.-D.

Remarks.

Zachvatkinia hydrobatidii was described by Dubinin (1949) based on specimens collected from the Wilson’s Storm Petrel, O. oceanicus in Massachusetts (USA), and also from 10 other storm petrels of the genera Fregetta , Garrodia , Pelagodroma ( Oceanitidae ), and Oceanodroma ( Hydrobatidae ) from various parts of the world. Mironov (1989) re-examined most of this material and referred to this mite species only the specimens from the oceanitids O. oceanicus and F. tropica . In Antarctica, Z. hydrobatidii was previously reported from O. oceanicus , F. tropica , and Pagodroma nivea (Forster) ( Procellariidae ) ( Atyeo and Peterson 1967, 1970). The record from the procellariid host seems to be questionable. Zachvatkinia hydrobatidii is very close to Z. oceanodromae Mironov, 1989 associated with storm petrels of the genus Oceanodroma , and differs in having the following features: in males, the genital arch is shaped as a completely closed ring, and the distance between setae ps1 and h3 is less than 40; in females, the posterior margin of the opisthosoma between the terminal extensions is not sclerotized, and setae e1 are situated on the inner margins of the lateral hysteronotal shields ( Mironov 1989).

Molecular data.

The COI sequences were obtained from two individuals and deposited in GenBank with accession numbers MZ489645 and MZ489646.
