Eudasyphora - Eudasyphora cyanicolor - male

Eudasyphora - Eudasyphora cyanicolor - Male
Tippecanoe County, Indiana, USA
October 15, 2008
Size: ~ 6 mm
Collected October 2008 in Lindgren funnel trap. Specific date is arbitrary to fulfill BG's date system.

Fairly sure this is a Eudasyphora male, which is a new genus for BG.

Hypopleura lacks bristles, indicating this is not a Calliphorid. I then ran it through the key in MoND vol 2 and it keyed out well.

I'd be interested in knowing how to tell the 3 NA species apart, if anyone knows.

Moved from Eudasyphora.

Key characters
If this is a Eudasyphora male -- I can't tell -- it is probably E. cyanicolor.

E. canadiana has "sternopleura with glossy patch posteriorly" (vs. evenly dusted in cyanicolor), male squamae dark brown or white (vs. light brown).

Overlapping characters are t2 has 4 to 6 p setae (including pd) in cyanicolor and 4 to 7 in canadiana. T2 has only one strong ad seta, distal to pd, but may have a second, smaller seta in canadiana.

The fore spiracle of canadiana is black. Cuny doesn't say for cyanicolor.

The third American species lives elsewhere.

Just a note
Cuny states that Eudasyphora canadiana and E. cyanicolor setosa hybridizes "quite frequently".

I looked again at this specimen, as well as several females collected at the same time, and I can't come up with anything other than Eudasyphora.

Can you elaborate on the abbreviations (t2, etc.), I'm still learning this stuff. :)

T is for tibia
Tibia, posterior, anterodorsal, posterodorsal.

Thats what I thought they meant, but wasn't sure if t2 was different than T2. Dipteran nomenclature can be a headache!
