Comment: The genus Nites in North America contains five similar species, all of which could occur in Massachusetts. They are best distinguished by genitalia dissection and/or DNA. As none of the few specimens reported from the from the State have so far been dissected, it is not known to which species they actually belong. 'Nites grotella' was the first species to be reported, from Martha's Vineyard in 1942. This 'species' is therefore considered to be a species complex on this site until more is known about the species which actually occur.
