Facts
On 13Jun2013, an adult male Phlugis sp. was collected in Davie, FL, by sweeping the vegetation in a field across a street from a business that sold landscaping plants. The collector was Stephen Beidler, a Nursery Inspector employed by the Florida Division of Plant Industry. The specimen was preserved in alcohol and submitted for identification to Paul Skelley, Entomologist for FDACS-DPI. Recognizing it was something new, Skelley took it to T.J.Walker for help. Walker quickly recognized it as a member of the predatory genus Phlugis, which occurs natively in Central and South America. Learning that Phlugis was a diverse but little studied genus, Skelley contacted David Nickle, USDA, the orthopterist who had most recently published on the genus. The specimen was sent to Nickle in anticipation that he might be able to identify it to species.

In email of 27Sep2017, Vince Golia, who lives in Palm Beach County reported to TJW that he had recently collected “a pair of Listroscelidinae” at light traps in his backyard at 9841 Scribner Lane, Wellington, FL. He had collected the female on 19Jul2017 at his black-light trap and the male on 12Sep2017 at his mercury vapor light. He indicated he had identified the specimens as belonging to the subfamily Listroschelidinae by comparing them to pictures he found on the Internet. He attached this image as the one that led him to that conclusion.

The image of the Phlugis orioni holotype is linked to the OSFO page that gives access to six images of each of the 17 Peruvian species of Phlugis described by Nickle in 2003. [To see these images go to OSFO’s Phlugis page and click on the name of any of the species described in 2003 by Nickle. You will be rewarded with a series of six thumbnails that expand with a click, in the same fashion as does the thumbnail above.]

Two obvious questions, with best-guess answers
Are the three specimens of the same species?
It seems extremely unlikely that more than two species are involved, and, since the specimens should soon be compared, there is no need to speculate on the one species vs. two species question.

Are the Florida specimens the descendants of one or more recent introductions from the New World tropics?
That seems highly probable, because Phlugis spp., though small, are easily seen, active when disturbed, and striking in appearance. Being attracted to light also makes it more likely they would have been detected decades ago had they long been a part of south Florida's insect fauna.
