(See synonyms given in Vidrine 1996))

Report associated with sponges: This species was reported among sponge Spongilla lacustris from North America ( Crowell & Davids 1979). This species was also reported associated with sponges Dosilia radiospiculata , Trochospongilla horrida, T. Pennsylvanica , and T. leidii from Louisina, Louisiana, North America ( Vidrine et al.1986; Vidrine 1996).

Remarks: This was reported from encysted stages in the mussel (in suprabranchial chamber) Anodonta (= Pyganodon ) grandis (Say, 1829) from Louisiana, North America ( Vidrine et al. 1986). Molluscan hosts with mites in the mantle cavity: Amblem aplicata Say, 1871, Disconaias fimbriata (Frierson, 1907) , Elliptio crassidens (Lamarck, 1819) , Fusconaia askewi (Marsh, 1896) , Lampsilis hydiana (Lea, 1838) , Lampsilis teres (Rafinesque, 1820) , Potamilus fragilis, (Rafinesque, 1820) , Sagittunio subrostrata (Say, 1831) , Nephronaias sp. , Popenaias berezai Inoue et al. 2020 , Popenaias popei (Lea, 1857) , Pyganodon fragilis (Lamarck, 1819) , P. grandis , Quadrula quadrula (Rafinesque, 1820) , Cyclonaia spustulosa (Lea, 1831), Sphaerium simile (Say, 1817) , Toxolasma parvus (Barnes, 1823) , Tritogonia verrucosa (Rafinesque, 1820) , Uniomerus tetralasmus (Say, 1831) , and Leauniolienosus calliginosus (Lea, 1845) from Canada, Mexico, and USA, North America ( Vidrine 1996; Edwards & Vidrine 2013).The mussel names have been updated to match current taxonomic treatments (see Vidrine 2019, Vidrine & Edwards 2021). Crowell & Davids (1979) also commented: ‘The records of Wolcott (1899) and materials in the Ruth Marshall Collection appear to be a mixture of U. laurentiana and U. nearctica’. Also, the U. crassipes used in their molecular study was actually U. laurentiana ( Edwards et al. 2010) .
