My first impression is subfamily Steganinae. Edit: ...but the basal scutellar bristles are convergent. Edited by John Carr on 13-05-2025 17:11 |

Now I'm considering Ephydridae but I still can't place it. |

I'm not familiar with the genus, but I'm wondering whether the dark costal margin of the wing on this specimen best fits Guttipsilopa.

Should it be Guttipsilopa, it would seem to me most like G. dianneae as described by Wayne Mathis regarding the wings: "Wing generally lightly infuscate, anterior margin conspicuously darker brown, area along veins and crossveins slightly darker, transition from dark anterior margin to lighter coloration gradual but limited to a narrow zone." However, I am not great at interpreting morphological jargon and have little experience in attempting to key and identify based on complex features.

Reading Mathis' paper, I see the nearly indistinguishable Guttipsilopa umbrosa is known from Florida.

There are two species of Guttipsilopa (Nesopsilopa) in Florida and I suppose you probably have one of them. See Mathis, Wayne M. and Amnon Friedberg. 1980. A New Species of Nesopsilopa from Florida (Diptera: Ephydridae). The Florida Entomologist 63(3):279-281. https://journals....view/57489 |
