Hello,

I found a place full of this "mosquitos", the most of these diptera seems to be male (at the end of the abdomen there is a male genitalia, I think).
Can someone please help me to identificate the Genus and then I'll post the species of this zone?

16.11.2012 - Northeast Italy - Padua

Thanks for the Gen. but ... so these are all female! I read that the male genitalia is different, the female finish with the ovopositor (like in the photo)

In my zone/state we have only these species:

Family Trichoceridae

Trichocera (Trichocera) Meigen, 1803

Trichocera (Trichocera) hiemalis (De Geer, 1776) (N, S)
Trichocera (Trichocera) maculipennis Meigen, 1818 (N)
Trichocera (Trichocera) regelationis (Linnaeus, 1758) (N, S)

I hope it could help to identificate it.

Thanks
Marcello

The Trichocera maculipennis is different so I exclude it, the best choice I think is the Trichocera hiemalis, I look at the wing and the genitalia in the shot:

Hi,
besides those three species that you mentioned, there are three more given in the "Checklist delle specie della fauna Italiana":
Trichocera (Saltrichocera) annulata Meigen, 1818 (S, Si)
Trichocera (Saltrichocera) parva Meigen, 1804 (S)
Trichocera (Saltrichocera) saltator (Harris, 1776) (S)
All those three species are widely distributed around Europe, so I am sure they should live around Padua as well and should be considered as an option.

Moreover, there are four other species known from Italy and should also be considered:
Trichocera (Saltrichocera) hirta Starý & Martinovský, 1996
Trichocera (Saltrichocera) mutica Dahl, 1966
Trichocera (Saltrichocera) pubescens Starý & Martinovský, 1996
Trichocera (Saltrichocera) rufescens Edwards, 1921

Your last picture of the male genitalia is most probably that of T. S. annulata, but the earlier images of female ovipositors are not distinctive enough to tell the species. The problem is that females of several of the mentioned species are not know yet, so we can't be sure about what we see.

If you collected those trichocerids or any others, you could send them over to me for closer identification :)

Hi Andrius,

for first thing I want to thank you for the help :)

So, I didn't mentioned the other species because Padua is North Italy, the others are at South Italy: (N)= North and (S)= South, (Si)= Sicily.

There are thousand of this subjects, but I see the female a part from the male, maybe it's my impression but I never see male and female together.

I'll send you a pm so you can to explaine me how to send you the subjects :)

Thanks again!

Marcello

Hi Andrius!

Do you think the female in the photos could be the T. annulata?

Thanks ;)

Ciao,
Marcello
