Remarks.

Alloptes (Conuralloptes) chionis was described from specimens collected from Ch. minor (type host) on Heard Island and was also found on Ch. albus from the Gaston Islands (Atyeo and Person 1967). When this mite was described, the genus Alloptes had not yet been subdivided into subgenera. Gaud (1972) established three subgenera in this genus but did not consider the taxonomic position of this species. Mironov (2007) placed this mite in the subgenus Conuralloptes Conuralloptes based on the following characters: in both sexes, genual setae mG II are shaped as short and thick spines with bluntly rounded apices; in males, the opisthosoma is not enlarged apically, and idiosomal setae h3 are absent; in females, the idiosomal setae ps1 and f2 are present. The males of A. (C.) chionis can be distinguished from other species of the subgenus Conuralloptes Conuralloptes by the following combination of features: the anterior margin of the hysteronotal shield is slightly convex, the pregenital sclerites are free from each other and almost parallel, the adanal shields are C-shaped, and macrosetae h2 are flattened and slightly widened in the medial part ( Atyeo and Peterson 1967, 1970).

Molecular data.

The COI sequences were obtained from two individuals and deposited in GenBank with accession numbers MZ489639 and MZ489640.
