Davis’ Key to Species of the Genus Tibicen found in the Southeastern United States

Davis provided a key of cicadas that belong to the then genus Tibicen in his 1918 article Mississippi Cicadas, with a Key to the Species of the Southeastern United States from volume 26 of the Journal of The New York Entomological Society. Download it from archive.org. This guide works for the Northeast and Midwest as well.

Mississippi Cicadas

Since 1918, genus and some species names have changed, so I’m going to present the key here, with highlighted notes on the updated names + images (when I have them). I’ll try to replicate the formatting of the original document as best I can.

Here goes…

Key to Species of the Genus Tibicen found in the Southeastern United States [works for most states east of the Rocky Mountains].

Note: the cicadas in the key are now organized in three genera: Neotibicen (A B), Megatibicen (A BB), and Diceroprocta (AA).

A. Large, heavy-bodied species; head broad, uncus [male genitals] simple, and first cross vein in the fore wings starting from radius 3 far back or about one-third distant from base of the first marginal cell.

     B. Uncus longer than broad. Black species with green or greenish markings and black area on the central part of the abdomen beneath, except in sayi [sayi = Neotibicen tibicen tibicen], and new variety of davisi [new variety of davisi = Neotibicen davisi harnedi].

Note: this group of cicadas (B) are now organized under the genus Neotibicen, not Tibicen.

         C. Hind margin of pronotum or collar, green or greenish.

             A narrow irregular area of black on the under side of the abdomen; opercula short and broad, and usually in the males an attenuated, pruinose [frosty white] stripe each side on the dorsum of segment three … pruinosa (Say). [pruinosa = Neotibicen pruinosus pruinosus].

N. pruinosus

             Dorsum of abdomen with the hind margin of the segments more or less brown and generally but a trace of pruinose stripe each side on segment three … pruinosa var. winnemanna (Davis) [pruinosa var. winnemanna = Neotibicen winnemanna].

[Generally speaking, east of the Appalachian mountains, you’ll find Neotibicen winnemanna, and west, it’s Neotibicen pruinosus.]

             Dorsum of abdomen shining black with a broad pruinose mark each side on segment three; blackened area on under side of abdomen more in the nature of an even stripe … pruinosa var latifasciata (Davis) [pruinosa var. latifasciata = Neotibicen latifasciatus].

             A longitudinal band of black on the under side of the abdomen, the opercula more lobate, and the margin of the front wings suddenly bent near the middle … linnei (Smith & Grossbeck) [linnei = Neotibicen linnei].

Neotibicen linnei

             A definite longitudinal band of black on the under side of the abdomen; head with the front rather prominent. Not a large species … canicularis (Harris) [canicularis = Neotibicen canicularis].

             An irregular band of black on the under side of the abdomen, head rounded in front; a rather small species … davisi (Smith & Grossbeck) [davisi = Neotibicen davisi davisi].

             Abdomen greenish centrally on under side, blackened area wanting, marginal cells of fore wings clouded … davisi var. harnedi new variety [davisi var. harnedi = Neotibicen davisi harnedi].

        CC. Hind margin of pronotum or collar black or nearly so (except in sayi var. australis).

            D. Central area of the abdomen beneath black.

                 Opercula long and with the legs usually somewhat chest- nut colored ; the uncus when seen in profile forked, resembling the open mouth of a snake … similaris (Smith & Grossbeck) [similaris = Neotibicen similaris similaris].

                 Opercula much shorter, more rounded, and the black area on the under side of the abdomen in the nature of an even stripe. Uncus not forked … lyricen (De Geer) [lyricen = Neotibicen lyricen lyricen].

                 Blacker than typical lyricen, lacking the considerable amount of fulvous markings on the pronotum and mesonotum. A fulvous somewhat anchor-shaped mark centrally on the pronotum … lyricen var. engelhardti (Davis) [lyricen var. engelhardti = Neotibicen lyricen engelhardti].

            DD. Central area of the abdomen not black beneath, often pruinose, as well as the long opercula.

                 Collar black, often with a greenish spot each side near the outer angles. … sayi (Smith & Grossbeck) [sayi = Neotibicen tibicen tibicen].

                 Collar all green or nearly so, as well as the pronotum and mesonotum … sayi var. australis (Davis) [sayi = Neotibicen tibicen australis].

    BB. The uncus is broad at the base, triangular in shape, and generally about as broad as long. Opercula broad and rounded at the extremities no definite black area on the central part of the abdomen beneath, usually unicolorus.

Note: this group of cicadas (BB) are now organized under the genus Megatibicen, not Tibicen.

         E. Wings long and narrow, collar 2 mm. or less in breadth at central portions ; dorsum of abdomen black or nearly so.

             Basal cell of fore wings rusty in color, anal cells (membranes) of both pair of wings gray; usually expands 110 mm. or more … resonans (Walker) [resonans = Megatibicen resonans].

Name, Location and Description

Locations from Wm. T. Davis’ MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES1

Prof. R. W. Harned has contributed the following note : “In regard to the distribution of Tibicen vitripennis I am inclined to think that this insect will only be found on low ground or in swampy places. This insect seems to be fairly prevalent in what is known as the delta section of Mississippi or the Yazoo-Mississippi Delta. This is the alluvial western part of the state. This species is also fairly abun- dant in* similar soils in Arkansas and Louisiana. The first time that I ever noticed this species was late in June, 1912. I found them quite numerous in fields at Palmyra Island, south of Vicksburg. I was surprised to find them coming out of the ground several hundred yards away from any perennial plants. They were also emerging from soil that had been under water a few weeks before. The spe- cies is quite common in the cotton fields of the delta.”
The distribution seems to be confined to the central United States. Specimens have been examined from Mississippi, Louisiana, Arkan- sas, Oklahoma, Kansas, Nebraska and Indiana.

Key to Species:

AA. Small species; uncus wish-bone shaped, and first cross view in the fore wings starting from about the middle of the first marginal cell.

GG. First and second cross veins of fore wings not clouded, wings clear throughout and expanding about 70 mm.

Head proportionately smaller than in the last; front more pro- truding;- collar not so contrastingly colored and fore wings narrower vitripennis (Say).

A visual description from Wm. T Davis’ NOTES ON CICADAS FROM THE UNITED STATES WITH DESCRIPTIONS OF SEVERAL NEW SPECIES 2

What we have identified as this species is an insect with green in its coloring as mentioned by its describer; not entirely orange and black as in Cicada eugraphica from further west.

Classification:

Family: Cicadidae
Subfamily: Cicadinae
Tribe: Cryptotympanini
Subtribe: Cryptotympanina
Genus: Diceroprocta
Species: Diceroprocta vitripennis (Say, 1830)

Diceroprocta vitripennis. out in Mississippi

Filed under: Cryptotympanini | Diceroprocta | Paul Krombholz | United States — Tags: — Dan @ 9:34 am

Here’s a break in the Magicicada mania: a Diceroprocta vitripennis. This photo was taken by Cicada Mania regular Paul Krombholz in Jackson Mississippi just last week. Cicadas like Diceroprocta vitripennis are annual cicadas: they emerge each year in small numbers, and as you can see, they rely on camouflage for survival. Annual cicadas are also quite shy compared to the periodic Magicicadas — they have very different life strategies. American annual cicadas rely on stealth and cunning to survive while searching for a mate. Periodic cicadas rely on the fact that there are so many of them, that some will always survive to carry on the species.

Notes from Paul:

I am continuing this season to try to get pictures of all the cicadas in the
Jackson, Mississippi area. I just got a female specimen of Diceroprocta
vitripennis. I found it in low vegetation on a sand bar next to the Pearl
River. Thanks to John Davis and the collectors at the Mississippi Museum of
Science for the tip on where to look for them! From head to wing tips, it
is 38 mm, but the wings of this species are longer in relation to body
length than those of Tibicens. Body length of this vitripennis was only
22mm.
