( Figs. 3 , 9 , 13 )

HOLOTYPE. ♂. COSTA RICA: Puntarenas: 3km SW Rincon , 8.68°N, 83.48°W, 10m, ♂, vii–ix, 1990, P.Hanson, Malaise trap [ LACMN ENT 043400 ] ( MUCR).

No sequence information is available for this species.

Distribution. This species is known from the Pacific lowlands of the base of the Osa Peninsula in Costa Rica, and from a mid-elevation forest in Ecuador.

Etymology. The species name pacifica refers to the Pacific Ocean coast of Costa Rica, where most specimens have been collected.
