Naturhistorika Riksmuseum , Stockholm , Sweden . Type locality and habitat. Paulet Island , Antarctic Peninsula , 15 January 1902 , in wet moss. Note. Specimens reported by Womersley (1937: 17) as Hydrogamasus antarcticus were later described as Parasitiphis aurora Lee, 1970 : 123 . We have examined a syntype female of H . antarcticus (from the Stockholm Museum), as well as specimens of this species from Macquarie Island (in ANIC ) . In both cases the insemination pore is located on the posterodistal face of coxa III, and opens into a short sclerotised basal section of the spermathecal duct within coxa III. This information has been incorporated into the genus concept for Hydrogamasellus . Some of the specimens in Trägårdh's syntype series were misidentified, and actually belong to Hydrogamasellus racovitzai ( Trouessart, 1903 ) . This error was noted on the specimen labels by D. C. Lee when he examined these specimens in 1966.
