Hello,

I photographed this fly in Bazzano (AQ), Italy, on May 2nd 2019. I think it's a Psychodidae, but is it possible to identify the genus or species from this photo?

Thank you in advance,
Emanuele

It look s a bit like Clogmia rothschildi. I do not know which resembling species there are in Italy!

---

C. latipennis is an Italian Clogmia. I have never seen one, only the description.

---

It could be latipennis, and then it's the first picture I have ever seen of it! I have a description (c'è in italiano!).

---

I am quite sure about Clogmia latipennis. May I use the picture as reference? Grazie.

---

Amazing, thank you very much Weia!


Yes, you can use it. Just one question: where can I find the description of this species?

---

I made a picture of the description from 1953. PLease make a list of things you think are visible on your picture and things that aren't. Black hairs on the face is a big difference with C. rothschildi. I hope the rest fits too.

---

To be precise: only description of hair and hair pattern are visible on the picture. Genitalia, eye bridge etcetera are not visbile and at the moment not important.

Thank you. I compared the description with this photo and another one I took at another specimen on May 2nd 2020 in Bazzano (AQ), Italy. I tried to look for similarities, but I'm no expert and I probably interpreted some things wrong, however, the features that in my opinion match are:

-Tufts of white hair at the base of the wing. (Ciuffi di peli bianchi […] alla base dell'ala).
-A large tuft of white hair at the tip of the subcosta (un grande ciuffo all'estremità della subcosta).
-(...) before the tip of cu_1b, where there is a big tuft of white hair similar to the one on the subcosta. ([…] prima dell'estremità di cu_1b, dove vi è un ciuffo grande simile a quello sulla subcosta).
-White fringe of the tip of r₂ to the tip of cu_1b and between cu_1b and a, not pure white in colour. (Frangia alare bianca dell'estremità di r₂ all'estremità di cu_1b, e poi fra cu_1b ed a, peraltro di un bianco non completamente puro.).

I'm not so sure of all the other features regarding the habitus and the wing venation because from the picture I wasn't able to read well the subscripts of the wing veins' names.

The last feature that seems to match comes from the Antennae description: segments of the flagellum of decreasing size towards the tip and "flask-shaped" (Articoli del flagello di dimensioni decrescenti verso l'apice, a forma di fiasco.).

This species is very common especially in May, so I will definitely try to take better photos from other angles whenever possible.

How is this species distinguished from C. rothschildi?

---

Rothschildi does not have that black on/behind the head.

Can you open this" https://waarneming.nl/soort/info/555932

---

I had to register, but then I could. Thanks. I see what you mean.

---

Did you see them again?

---

I'm sorry for the late reply.
I found a few specimens during the winter and only one this spring, but I photographed just one of them on October 27th.

When you find a dead one maybe a taxonomist will be glad to see it. The original decription is said to be 'poor'.

The species has been photographed in Italy (you), Spain, France south and north, England south and last week Netherlands.
Main difference is the colouring of the thorax, and there is a subtle difference in the white hairs close to the border of the wing. Latipennis also is significantly bigger than rothschildi, at least 25%. Last friday I'v pictured 16 latipennis and 1 rothschildi at the same scale.
Yours definitely is latipennis!
