Five new species of Coelidia are described and illustrated. These include panamensis and simplex from Panama and retrorsa, cochloea, and tortula from Brazil. A revised key is also presented for 13 of the 14 species for which males are known. Coelidia gladia is proposed as a new name for Coelidia spangbergi Nielson, 1982 nec Coelidia spangbergi Linnavuori, 1956 and Coelidia spangbergi Metcalf, 1964.
