Descriptions from Wm. T. Davis from RECORDS OF CICADAS FROM NORTH AMERICA WITH DESCRIPTIONS OF NEW SPECIES1
Note: at the time Davis assigned Diceroprocta apache to the Tibicen Latreille, 1825 genus. It’s since been moved to Diceroprocta Stål, 1870.
Resembles Tibicen cinctifcra (Uhler), but has sharper pointed opercula, the outer sides of which are not parallel, but converge; is without the central pruinose spot at the base of the tergum, and instead of having the dorsal part of segment eight all pruinose, the whitened area is reduced to two spots with a black space between. In the allotype the plates that correspond to the opercula of the male, are sharper pointed than in cinctifcra, the double notch in the last ventral segment is usually deeper, the terminal spine is more robust, that is, has a broader base, and the abdomen is less tapering at the extremity. In the three types of Uhler’s cinctifcra in the United States National Museum, the costal margin of the fore wing is bright orange to the end of the radial cell, also the hind margin of the pronotum or collar, whereas in apache the color is light yellow or straw-color. The membranes at the base of both pairs of wings are orange or at least usually much darker than in apache, where they are white or light gray. Some of these differences in strudture and color are more clearly brought out in the illustrations.
Two varieties of Cicada alacris – note the rounded shape of the operculum:
The illustration comes from Biologia Centrali-Americana. Insecta. Rhynchota. Hemiptera-Homoptera. Vol. 1. By W. L. Distant F.E.S. and The Rev. Canon W. W. Fowler, F.L.S. (1881-1905). Read it on the Biodiversity Heritage Library website.
Here’s another fungi story coming from the WVU Kasson Lab: Cordyceps infected Citrus Cicadas (Diceroprocta apache).
The story goes like this: because of Ed Yong’s article about the Massospora fungus that infects cicadas, someone sent the Kasson Lab photos, and then samples, of Diceroprocta apache (Citrus Cicadas) infected with a different type of fungus: Cordyceps. Looks like the lab is going to study this fungus, and I’m sure they’ll produce a paper.
One cool thing about being a cicada fan is your friends will send you cicadas from their part of the world. This male Diceroprocta apache cicada is courtesy of my friend Shannon, who lives in Las Vegas, NV. They’re out in large numbers from June to July.
Diceroprocta apache, aka the Citrus cicada, is the only member of the Diceroprocta genus that lives in Nevada. It can also be found in Arizona, California, Colorado and Utah.
Here is a playlist of YouTube videos to watch if you want to hear what they sound and look like when they’re still alive:
If you’re in Las Vegas and hear an electrical buzzing sound, it might be a Citrus cicada.
Comments Off on A Diceroprocta apache (Davis, 1921) from Las Vegas
It could be apache or it might be semicincta, depending on where he got it from. But from the pics/specimens we have I think it does look more like apache. We’ve never noticed one with red eyes either but then Dave and I have only collected apache and semicincta once in 2003, so we haven’t seen very many. I don’t know of any other Diceroproctas that it could be. Apache/semicincta are very common in parts of Arizona. I think they are parapatric.
Bill Sheridan has contributed this excellent photo of an Apache cicada, often confused with Magicicadas because of the red eyes and black body.
