Tripudia quadrifera. This species was shown to be a species complex by Pogue (2009a) with T. quadrifera confined in the United States to Texas. Tripudia rectangula occupies most the remainder of the North American range, and two additional species, T. grapholithoides and T. lamina, occur in Florida where they are sympatric with T. rectangula.
