Hairy Midge - male

Hairy Midge - Male
Guelph, Wellington, Ontario, Canada
May 24, 2007
Size: ~ 4 mm
Either this midge is hairier than most of the ones I've seen, or all of them are this hairy but so finely so that I didn't notice until now...

Moved
Moved from Tanypodinae.

Maybe Thienemannimyia senata
This matches fairly well, so far as can be seen, Roback's(1) description of Thienemannimyia senata. This species is common in Ontario (by the standards of Tanypodinae, which isn't very common). Roback identified several specimens in the Canadian National Collection. (See http://books.google.com/books?id=lYTr8SHK1u0C&pg=PA240 and synonymy on previous page.) Do you ever have a chance to examine that collection? I wouldn't give an ID based on this picture without comparing to a reliably identified specimen or picture.

 
More like Larsia
The genitalia are too long and thin for Thienemannimyia. It looks like one I shot that I tentatively IDed as Larsia but noted the color pattern does not match any of the species.

 
CNC
Thanks for your help. I have not been to the CNC, unfortunately. Don't know when I may get the chance.

Moved
Moved from Midges. Apparently something in tribe Pentaneurini.

Hair
This may be one of the less commonly seen subfamilies, as it seems to have an extra crossvein in its wing.

(Based on visible wing veins: Tanypodinae and Diamesinae seem likely.)
