Greetings,
I have seen these gnats at work that caught my attention, having marked wings and slightly flattened antennae. I caught them, and attempted to key it out using several keys. There weren't really any problems with keying, it seemed to fit a keroplatid in the genus Lyprauta to me, with the anterior apical bristles on the tibiae reduced. I found that the genus is Neotropical with some native species here but the form I have does not seem to be recorded for the United States and Canada. The gonostylus has 2 apical and subapical teeth that are black and sclerotized at the tips. I believe members of the genus Lyprauta with these features are a first for here, but I was located not far from a botanical garden with many non-native plants. I've read some papers about members of the genus being brought by potted plants in greenhouses. I've attempted to contact several people without luck. It does indeed look very much like Lyprauta cambria, described recently
from a greenhouse, probably originating from the Neotropics, but the gonostylus appears to be rotated. If anybody has insight, agreement or disagreement, let me know!
