Hello, I've found this 2 mm long Psychodidae in Lyon metropolis area, center-east of France, on March 12, 2026 in a building entrance. It does not look like the usual Clogmia albipunctata. With the margin setae black except on the apical side where they are white, the pattern of the wings, and the white segments on the legs, I was thinking to either genus Pneumia or Pericoma. What do you think? I've collected it so I can try to dissect in looking for aedeagus but I don't know what they looks like for these. Lagides attached the following image:  [295.06Kb] French naturalist specialized in spiders. Curiosity is a duty: the duty to know. |

It definitely is in tribus Pericomaini, where such white hairs at the end of the veins can be found in many Pericoma species, in Berdeniella and also in one Ulomyia species. The light body hairs point to Berdeniella, but the black hairs on the wings do not. I think it is in Pericoma, but then it becomes difficult. I do not know how many species in Lyon occur that do not live in my region (Netherlands and Belgium). Maybe, but not sure at all, Pericoma pseudexquisita is a good candidate.

Thanks for your reply. Are there any criteria I could image (I have both a stereomicroscope and a microscope) that could confirm (or invalidate) your proposition ? French naturalist specialized in spiders. Curiosity is a duty: the duty to know. |
