Only a few species in the genus "Oncocnemus" occur in eastern North America, including this species. Many more species in the genus occur in the American Southwest (Wagner et al. 2008).

State Ranking Justification [-]
One population is documented in Suffolk County. In New York State, the species is likely restricted to Long Island and nearby offshore islands, since it seems to be a Great Lakes and Atlantic Coast species (Wagner et al. 2008). Additional surveys are needed to better understand its status and distribution in New York State.
