چکیده
Ongoing studies in South America of phorid flies of the genus Pseudacteon Coquillett 1907 have revealed two further new species in this genus that are described here: P. obtusitus and P. notocaudatus. Both species are parasitoids of Solenopsis (F.) fire ants.

New species and records of Pseudacteon Coquillett, 1907 (Diptera, Phoridae), parasitoids of the fire ant Solenopsis geminata group (Hymenoptera, Formicidae).
The genus Pseudacteon Coquillett (Diptera, Phoridae) has a worldwide distribution and comprises parasitic myrmecophilous species that decapitate host ants. Seventy one species are known in the genus, 41 of them occur in the Neotropical Region and are 25 from Brazil. In northeastern Brazil, there are only records for two species, Pseudacteon dentiger Borgmeier and Pseudacteon antiguensis Malloch...
متن کاملHost Specificity in Two Additional Pseudacteon Spp. (diptera: Phoridae), Parasitoids of Solenopsis Fire Ants (hymenoptera: Formicidae)
We tested the host specificity of two South American Pseudacteon phorid flies, P. obtusus Borgmeier and P. borgmeieri Schmitz, on North American colonies of the red imported fire ant, Solenopsis invicta Buren, and the tropical fire ant, S. geminata (F.). Sequential host specificity tests conducted in the laboratory indicated that P. obtusus was highly specific to S. invicta . In individual tria...

The phenology and dispersal abilities of Pseudacteon phorid ßies, parasitoids of Solenopsis Þre ants, were measured at multiple sites over several years. Four Pseudacteon species [P. browni Disney, P. spatulatus (Malloch), P. crawfordi Coquillett, and an undescribed species, P. sp. A.] were found in the vicinity of 5 S. geminata (F.) populations over a 3-yr period. P. browni was the most common...
متن کاملCytogenetic analysis of three species of Pseudacteon (Diptera, Phoridae) parasitoids of the fire ants using standard and molecular techniques
Pseudacteon flies, parasitoids of worker ants, are being intensively studied as potentially effective agents in the biological control of the invasive pest fire ant genus Solenopsis (Hymenoptera: Formicidae). This is the first attempt to describe the karyotype of P. curvatus Borgmeier, P. nocens Borgmeier and P. tricuspis Borgmeier. The three species possess 2n = 6; chromosomes I and II were me...
متن کاملDistributional Patterns of Pseudacteon Associated with the Solenopsis saevissima Complex in South America
Classical biological control efforts against imported fire ants have largely involved the use of Pseudacteon parasitoids. To facilitate further exploration for species and population biotypes a database of collection records for Pseudacteon species was organized, including those from the literature and other sources. These data were then used to map the geographical ranges of species associated...
