The genus Glutops has been known to contain but one species, the very rare fly Glutops singularis Burgess. Probably most of the collection records of G. singularis have been published and these number less than a dozen, the records being restricted to the states of New Hampshire, Massachusetts, Connecticut, New York and Pennsylvania. To the published records the writer might add that of a female specimen collected at the Cornell Wild Flower Preserve, Slaterville, New York, on June 1, 1935.
