Discussion: In the family Oribatulidae, Scheloribates laevigatas 

 (Koch) is the principal vector of the various tapeworms. To date, four 

 other species are also involved. S. laevigatas is the intermediate host 

 of Moniezia expansa in the United States and Russia; of M. benedeni 

 in Russia; of Bertiella studeri, Cittotaenia ctenoides, and C. denticulata 

 in Germany; and of Anoplocephala perfoliata, A. magna and Thysa- 

 niezia giardi in Russia. Scheloribates latipes (Koch) is the interme- 

 diate host of Anoplocephala perfoliata and Thysaniezia giardi in 

 Russia. Protoschelobates seghettii Runkel and Kates and Oribatula 

 minuta (Ewing) are intermediate hosts of Moniezia expansa in the 

 United States. Liebstadia similis (Michael) is the vector of Cittotaenia 

 ctenoides in Germany. Kates and Runkel 1948 give an excellent review 

 of the biology and distributions of the oribatid mites which are vectors 

 of the tapeworms and their work should be consulted for further details.
