Lithacodia costaricana. The aberrational and unavailable name Lithacodia musta ab. costaricana Strand, 1917, described from Costa Rica, was raised to species status and validated as Lithacodia costaricana Franclemont and Todd, 1983 when specimens resembling L. costaricana were found to occur in southwestern United States. Material from Arizona shows significant differences in the male genitalia from L. costaricana, and also from the similar Lithacodia mustapha Dyar, [holotype in USNM], described from southern Mexico, so the Arizona material is listed as an undescribed species.
