discussion
Remarks: Halobiotus species are true secondarily marine species, although a few other eutardigrades are known from river estuaries where the salinity is very low, e. g. Isohypsibius granditintinus Chang & Rho, 1997 c (Chang & Rho 1997 c). Known only from the type locality, H. arcturulius is very similar to H. stenostomus and some records of this latter species may in fact belong to H. arcturulius (for more detail see remarks for H. stenostomus).
