It is doubtful that any infraspecific taxa are currently recognized within this species. (If subspecies were accepted in the species, Utah populations would likely be assignable to what would be the type, or nominate, race, Succinea rusticana rusticana.)
Status in Utah
This species has been reported historically from 3 localities in 3 counties in north-central Utah: one locality each in Cache County (Henderson and Daniels 1917, Chamberlin and Jones 1929), Morgan County (Henderson and Daniels 1917), and Salt Lake County (Woolstenhulme 1942a).
The only report of this species in Utah that mentions numbers of this species was that of Woolstenhulme (1942a), "3 specimens", and even this report does not indicate whether any of the 3 specimens were alive. Thus, abundance of this species in Utah is unknown.
Threats to this species in Utah are not known. However, since the species utilizes wet sites and may even be semi-aquatic, dewatering (e.g., through diversions of streams for irrigation and other purposes), alteration of aquatic habitats (e.g., damming of streams), and degradation of water quality (e.g., pollution) may be threats. Population trend of this species in Utah is unknown.
Inventory is needed in at least north-central Utah to determine whether this species is extant in areas of its reported historical occurrence as well as to assess its abundance and the extent of its distribution in the state.
Members of the family Succineidae are among the most difficult to identify of all mollusks, with even identification to genus being no simple matter. Thus, it is possible that this organism has been collected in Utah but not identified to species or that Utah specimens have been misidentified as other species that are more common.
Habitats Utilized in Utah
Henderson and Daniels (1917) are the only authors who have reported habitat information for this species in Utah. One of the two Utah sites where they collected the species they described as "a small stream choked with water-cress" and the other as "pools beside [a] railroad track". Although their report does not specify where in relation to the stream and the pools they found this species, it is quite possible that they found these snails not only at the water's edge but actually in (i.e., under) the water, many species in this genus being amphibious.
