Resumen:
The first record of Caenocholax fenyesi parasitizing the red imported fire ant, Solenopsis invicta, in South America is documented. Caenocholax fenyesi males were collected from colonies of S. invicta in northeastern Argentina. This record helps to clarify the occurrence and host utilization of C. fenyesi in the United States, where S. invicta is an invasive exotic species. This record, along with other recent reports, suggests that C. fenyesi males are generalist parasites, not utilizing a narrow host range, as do most known strepsipterans. However, the potential presence of cryptic species is an alternate explanation.
