Niveria floridana was named by Olsson & Harbinson (1953). Although I did see someone synonymize this with the recent Niveria suffusa they did so without an explanation. N. floridana can be differentiated from N. suffusa by lacking the nodose ribs of the extant species. Reference Olsson, A.A., and A. Harbison. 1953 (1990 Reprint).

Niveria lindae is recognized by FLMNH in the Nashua Formation in North Florida. Petuch named it from shells that are from Lee Creek. A distinctive feature of Triviidae is the dorsal furrow. Petuch describes that of N. lindae as shallow with the ribs continuing across the furrow while the ribs in N. floridana (LINK) are separated completely by a deep furrow. Also N. lindae has approximately 30 ribs to around 20 in N. floridana. Reference Links FLMNH db Image Gallery ACTA Conchyliorum
