Distribution: Mexican states of Yucatan and Quintana Roo south through Guatemala and Honduras to Nicaragua.
Comment: The distribution of this and the nominate subspecies appears to be distinct, being separated by the Isthmus of Tehuantepec. Genitalic differences are relatively slight but consistent, suggesting that the two taxa may be distinct species. The lack of other characters for separating the two and the allopatric distribution suggest subspecific status, however.
This subspecies is dedicated to Dr. J. C. Schaffner of Texas A&M University for his contributions to the knowledge of Mexican Heteroptera and for the help and support he has given me.
