Remarks. Cook (1986) did not report this species from hyporheic habitats. As all my findings of M. parva are from hyporheic habitats, so this species is very likely is a true hyporheic species. In the surface sample of Barkers Creek only a female of M. australica Cook was found, while in the hyporheic sample only M. parva was found. Cook (1986) stated that M. parva should have a dorsal shield which is longer than wide, while M. australica has a dorsal shield which is wider than long. However, occasionally specimens of M. parva have been found with a dorsal shield equally long and wide or slightly more wide than long. Momoniella parva is smaller than M. australica , while there are differences in the genital field between the two species (see Cook, 1986).
