The species of Phora (Diptera: Phoridae) of Costa Rica.

The Phora of Costa Rica were reviewed and three species, all belonging to Schmitz's Group III, were recognized: P. americana Schmitz and Wirth, P. truncata new species and P. paramericana new species. Of the three species, P. americana is by far the most abundant, with the other two species being rarely collected. All specimens were collected in the central highlands of the country. The previous record of the Holarctic Region species P. stictica Meigen from Costa Rica was found to be based on a misidentification of P. truncata.
