DISTRIBUTION:

Pachygonidia hopfferi, (wingspan: males: mm; females: 74mm), flies in Panama and Costa Rica, and has been recorded as far south as Bolivia: La Paz: Nor Yungas, Coroico, 1200m; Cochabamba: Chapare, Yunga del Espíritu Santo.

Pachygonidia martini and P. hopfferi "can be easily separated by the form of the outer edge of the postmedian transverse band on the forewing. In P. martini it is wavy, whereas in P. hopfferi it is straight. The specimen illustrated by d'Abrera ([1987]: 109) as P. hopfferi is P. martini." Haxaire.

Perhaps the above specimen is P. martini.
