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.

Platypleura coelebs Stål, 1863

Species specimen description from A Monograph of Oriental Cicadas by W.L. Distant:

Head ochraceous; front, excluding a central spot, margins of vertex between front and eyes, and a transverse fascia between the eyes black; pronotum pale castaneous, the posterior and lateral margins ochraceous; mesonotum castaneous, with four large obconical black spots on anterior margin, the central two smallest, a central discal elongate black spot and a small black spot in front of each anterior angle of the basal cruciform elevation; abdomen black, the tympanal coverings, and the posterior segmental margins ochraceous. Head beneath, sternum, legs, rostrum and opercula ochraceous; a transverse fascia between the eyes — enclosing a pale spot on face — inner margins of eyes, posterior margin of face and apex of rostrum black: abdomen beneath castaneous, with the posterior segmental margins and the apes ochraceous.

Tegmina with about the basal half creamy opaque shaded with pale fuscous, and more or less outwardly defined by an indistinct curved pale fuscous fascia, remaining area hyaline, costal membrane and venation dark ochraceous, the transverse veins at the bases of the second, third, fourth, fifth and seventh apical areas slightly infuscated; wings stramineous for about two-thirds their area from base, this coloration outwardly margined with fuscous, remaining area pale hyaline, the venation dark ochraceous.

The rostrum extends a little beyond the inner angles of the opercula, which are somewhat well separated.

Long. excl. tegm. 22 to 23 millim. Exp. tegm. 64 to 68 millim. Exp. pronot. angl. 11 millim.

Diceroprocta alacris & Diceroprocta apache

Diceroprocta alacris & Diceroprocta apache are two cicadas, both found in Mexico. I’m covering them both in the same post because they were both formerly refrered to as Cicada transversa.

Diceroprocta apache

D. apache was formerly known as Cicada transversa.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Cryptotympanini
SubTribe: Cryptotympanina
Genus: Diceroprocta
Species: Diceroprocta apache (Davis, 1921)

D. apache, aka Citrus Cicada, is also found in the southern United States. Visit this page to listen to its song.

D. apache have triangle-shaped opercula.

Cicada transversa illustration from Insecta. Rhychota. – note the shape of the triangular shape of the opercula:

A photo of D. apache from my collection. Same/similar cicada? Maybe, maybe not. Note the opercula:

Diceroprocta alacris

There are two subspecies: D. alacris alacris (Stål, 1864) and D. alacris campechensis Davis, 1938.

Diceroprocta alacris was formerly known as Cicada alacris as well as Cicada transversa.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Cryptotympanini
SubTribe: Cryptotympanina
Genus: Diceroprocta
Species: Diceroprocta alacris
Subspecies: D. alacris alacris (Stål, 1864)
Subspecies: D. alacris campechensis Davis, 1938

Two varieties of Cicada alacris – note the rounded shape of the operculum:

Diceroprocta cinctifera

Diceroprocta cinctifera is found in North America, specifically the south-western United States and Mexico. There are three subspecies. It was formerly known as Cicada cinctifera. Yes, its name has changed.

Listen to its song.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Cryptotympanini
SubTribe: Cryptotympanina
Genera: Diceroprocta
Species: Diceroprocta cinctifera

Subspecies: Diceroprocta cinctifera viridicosta Davis, 1930

Diceroprocta cinctifera
The image says Cicada cinctifera, but the name of this cicada is Diceroprocta cinctifera.

Pacarina puella Davis, 1923
The image says Pacarina signifera but the newest name of this cicada is Pacarina puella.

Pacarina genus description by W. L. Distant:

Characters. — Head (including eyes) broader than base of mesonotum ; eyes projecting beyond anterior angles of pronotum ; vertex at area of ocelli much longer than front ; pronotum with the posterior angles moderately lobately produced, its lateral margins oblique, slightly sinuate, its length shorter than that of mesonotum ; abdomen about as long as space between apex of head and base of cruciform elevation; tympanal coverings distinct but inwardly concavely narrowed and exposing the tympanal cavities; face convex, a little broader than the space between it and eyes; opercula about reaching base of abdomen, their lateral margins oblique, their posterior margins a little rounded; anterior femora armed with two strong spines beneath; rostrum about reaching the posterior coxae; tegmina and wings hyaline; apical areas eight.
