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

I’ve been updating the North American cicada pages on this site, and I’ve been including snippets (and some chunks) from William T. Davis’ cicada papers from the early 1900s. They’re in the public domain and excellent resources.

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.

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.

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 simple, and first cross vein in the fore wings starting from radius 3 far back, or about one third distant from base of 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 stripe each side on the dorsum of segment three … pruinosa (Say). [pruinosa = Neotibicen pruinosus pruinosus].

N. 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

        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.

    BB. Uncus 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.

Wm T Davis’ 1910 description of Neotibicen lyricen engelhardti1

Cicada engelhardti n. sp.

Length: [male] 32 mm., to tip of wings, 50 mm.; [female] 30 mm., to tip of wings 50 mm.

Head black, sometimes with narrow, tawny stripe on front. Pro-thorax black, with small, greenish fulvous central arrow-shaped spot, broadest behind. In lyricen this spot is broadest in front. Posterior and lateral borders of the pronotum black. Mesothorax nearly all black, with two faint parenthesis-like lines of fulvous partly enclos- ing the central portion. Sometimes these lines are heavier and there is a shade of fulvous on the posterior portion of the mesothorax. The inner surface of the front marginal vein is usually back and darker than the same parts in lyricen. Abdomen black above, with two nar- row pruinose lines or spots at base. Beneath, with broad central black stripe and at each side is a broad lateral pruinose border.

This insect is blacker than Cicada lyricen, lacking the considerable amount of fulvous markings of that species, particularly on the pro- thorax.

Name, Location and Description

Wm. T. Davis description

Neotibicen latifasciatus was described in 1915 by Davis in the article Notes on Some Cicadas from the Eastern and Central United States with a Description of a New Variety of Cicada Pruinosa in the Journal of The New York Entomological Society. 1

Smith and Grossbeck say of the specimens they had from the coast of New Jersey and which we now know to be a variety: “Abdomen above black, base of first segment with a white, heavily pruinose lateral dash, which encroaches to some extent upon the second segment; a similar but longer and broader lateral dash extends along the base of the third segment and a spot of the same color is on each side of the eighth segment. In the female the dash of the second segment differs from that of the male in not becoming attenuated dorsally, but in being squarely truncated.”

For the variety thus described with the broad white lateral dashes on segment three, we propose the name of latifasciafa. We then have Cicada pruninosa [now Neotibicen pruinosus] as described by Say, with the tergum entirely black or nearly so, with the attenuated white stripe at the lateral base of the third abdominal segment, being the form common from Indiana, Missouri, Nebraska, Kansas, etc., of which we figure a male from Chetopa, Kansas ; Cicada pruinosa var. latifasciata so far known only from the coastal region of the eastern and southern United States, with the broad stripe on segment three and abdomen beneath more shining black, of which we figure a male from Cape May Co., New Jersey, and Cicada pruninosa var. winnemanna [now Neotibicen winnemanna] with the hind margins of the abdominal segments more or less fulvous, the second segment having the band broader than the others and a white streak generally hardly discernible each side at the base of the third segment, of which we figure a male from Plummer’s Island, Maryland. The females of these cicadas have the charactertistic markings far less distinct than in the males and occasionally some are entirely absent.

Identification key by Wm T Davis2

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

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.

Neotibicen davisi aka Davis’ Southeastern Dog-Day Cicada

Neotibicen davisi aka Davis’ Southeastern Dog-Day Cicada.

There are two sub-species of Neotibicen davisi, and it makes sense to discuss both on the name page.

  • Neotibicen davisi davisi (Smith and Grossbeck, 1907). Quick ID: it has black on its abdomen.
  • Neotibicen davisi hardeni Davis, 1918. Quick ID: it lacks the black on the abdomen, and is only found in Arkansas and Mississippi.

In this photo, N. davisi hardeni is on the left, and N. davisi davisi is on the right:

Tibicen davisi var. harnedi new variety, PI. VII, fig. 4.

Type male, Helena, Arkansas, June, 19 16 (K. D. Jacob). Davis
collection.

Allotype female, Rodney, Jefferson Co., Miss.. August, 1917 (O.
A. Hammett). Collection, Miss. Agri. and Mechanical College.

More robust than typical davisi, with broader wings, the first seven marginal cells of the fore wings being clouded much as in Tibicen superba Fitch. The dorsal markings are quite green in color, the central, green, wedge-shaped mark on the pronotum is not sepa- rated from the hind margin, but is confluent with it; the collar is bright green. The dorsal surface is less rusty in appearance than in typical davisi. Beneath the abdomen is greenish, without the “narrow black portion in the center,” as in typical davisi.

Location and song notes 1:

davisi occurs throughout the southeastern states as far north as New Jersey. Its song- is a continuous z-ing of short dura- tion, and is more sharp in tone, though not as loud as that produced by the larger, related black species.

Name, Location and Description

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 StĂĄl, 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.

Name, Location and Description

A description by Wm. T. Davis.

The description comes from Wm. T. Davis’ document A NEW VARIETY OF CICADA RESEMBLING C. DORSATA. from September, 2015, published in the Journal of the New York Entomological Society. Vol. 23: 161-164.

Markings resembling those of C. dorsata [now M. dorsatus], but marginata var. dealbata is more green in color and has less black about the central area of the pronotum. The mesonotum is marked as in dorsata but is more pruinose ; the turgum has a dorsal line of white spots as in dorsata, but the sides are broadly pruinose and the posterior margin of each segment is narrowly edged with greenish yellow. Beneath both insects may be of the same color, though dorsata is usually much darker. The opercula are about as broad as long and broadly rounded at the tips. The fore wings in dorsata are oval in shape with the inner side (radius) of the costal margin blackish ; the veins are heavy and thickened, and the W-mark is prominent, whereas in luarginata var. dealbata the fore wings are more acuminate in form, the costal margin is green, darkened beyond the middle of the wing and the W-mark is not conspicuous or is wanting. One of the greatest differences between the two insects is in the genitalia. The uncus in dorsata viewed at full face is narrow and the piece below into which it locks is broadly notched with the extremities rounded. In var. dealbata the uncus is more nearly triangular in shape and the lower piece is narrowly notched with the extremities much produced. The male type of var. dealbata is figured.

Length of body 35 mm. ; length of fore wing 46 mm. ; expanse of wings 105 mm.
