BG1358 D0441 - Diogmites properans - female

BG1358 D0441 - Diogmites properans - Female
Decatur County, Georgia, USA
July 6, 2007
Size: body length 20.5 mm.
According to Norman Lavers (See his comments here), the yellow bristles on the sides of the first abdominal segment are diagnostic for Diogmites angustipennis. The second image in this series is an enlarged view of these bristles. Since D. angustipennis is not on the Georgia list, I felt that I needed ID confirmation before moving images to the guide page.
Confirmation would be appreciated.

First of all, I think the genus Diogmites
is a mess that DNA will eventually have to clear up. But second, I think I owe apologies for bad or misleading advice on this one. At this date I don't know what I had in mind when I made those comments about bristle color, but I think it was for that particular individual you cite, and was not meant as a general statement. I think most of the yellowy Diogmites have yellow bristles on the first abdominal segment, and in that case I meant to distinguish it from some darker species (basalis, discolor, platypterus) that have black bristles there. Anyway, this species here from Georgia (angustipennis does not appear to extend much east of Louisiana) seems to me to key out to D. properans (using Artigas's key to Eastern Diogmites). (The advantage of these perfect photos means it is practical to key from photographs.) So with embarrassment, I am moving it there. N.L.

 
You are forgiven,
especially since you referred to our photos as "perfect"!

Yes
D. angustipennis was not listed for AR originally but we now know they are the most common Diogmites in my state and, in fact, occur in my front yard. This is D. angustipennis. Beware of D. symmachus and a D. new species as you move westward towards TX and perhaps LA.

 
Thanks Herschel
We appreciate your interest and help.
