Cicada - Diceroprocta semicincta

Age

I'm just curious to know how old these specimens are. They certainly do not look like the Tibicen chloromera currently in the guide. The pronotal collars of these specimens are white whereas the T. chloromera that I know have black pronotal collars. Also The pronotums of these specimens are totally black whereas T. chlormera have green ones. Not to mention the opercula in the middle is shaped differently and also this specimen seems to lack any pruinosity in the ventral view.

My specimen was about 4 hours old when I photographed it. I found that it is more likely to be 'Tibicen chloromera' according to this Arizona edu page.

Diceroprocta?

I've been looking online for a while and the only specimen that I found that is an exact match for yours is here:

http://artattack.to/display.php?art=1000021622

Those species isn't mentioned.

While this species seems to be native to Arizona I think that the specimen in Arizona that you site is also mis-identified. When comparing your specimens with the one there, they don't seem to key out the same.

I'm leaning more towards a Diceroprocta species. Maybe we should send the image to Dr. Hamilton for a third opinion.

I can also send the image to some colleagues at University of Connecticut at Storrs.

Diceroprocta.

I agree with Gerry, this is a male Diceroprocta, probably D. semitincta. That is the dominant species here in Tucson, anyway:-)

Image

I found an image of D. semicincta which I can see the white band on the back of the head.

Yes but...

I saw this one also but I ruled it out. The color to me seems off. I can see it is male and the opercula are definately shaped like the opercula in your image. It's the color that is throwing me. Your specimens are nearly black (black pronotum and mesonotum) like the image I referenced earlier. The new image the pronotum and mesonotum are not black.

I have an email inquiry out to Dr. Alan Sanborn. If he can't ID these then I don't know who can. (Just kidding) someone will I'm sure.

Opinions

Yes, I think more opinions would be good.

Confirmation

From Dr. Alan Sanborn:

Quote:

The cicada pictured is Diceroprocta semicincta. A common species from southern and central Arizona. The curved opercula give it away rather quickly.

Chalk one up for Eric, he got it right!

Cool

So, I should move this one now?

… Buggz, 2 August, 2006 - 6:02pm

Absolutely

I think a page may need to be created though.

Dr. Alan Sanborn is the premier man for Cicadas. He will be publishing a book entitled "North American Cicadas" which will be released soon. I believe he'll have information on all the species along with their distribution.

Moved to new page

- thanks to everyone who worked on the identification - it seems to have been quite a team effort!
