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

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.

Diceroprocta alacris

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

Diceroprocta biconica (Walker, 1850)

It is found in Cuba and Florida in the U.S.:

Diceroprocta biconica (Walker, 1850)
The image says Rihana biconica, but the newest name of this cicada is Diceroprocta biconica.

For the fun of it, here is a genus description for Rihana:

Characters. — Flead distinctly longer than half the breadth between eyes, and including eyes wider than base of mesonotum ; face more or less prominent, its lateral margins in line with lateral margins of vertex; eyes oblique, longer than broad; pronotum a little narrowed behind eyes, about or almost as long as mesonotum in front of cruciform elevation ; abdomen not, or scarcely, longer than length between apex of face and base of cruciform elevation ; other characters generally as in Cicada.

Cordyceps infected Citrus Cicadas

Filed under: Cordyceps | Diceroprocta — Tags: — Dan @ 9:44 am

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.

Head above black with a dark yellowish spot each side between the antenna and the eye and an irregular one each side of the ocelli at the back of the head and extending to back of the eye. Pronotum blackish, shining, with the posterior marginal band olive colored, the band extending along the sides to the anterior angles, the posterior angles of the pronotum, however, are fuscous. Mesonotum shining chocolate-colored, the elevated X olive, and the sides of that color also to the base of the fore wings where there is an orange spot seen only when the insect is expanded. The outer sides of the W-mark are faintly outlined in part with olive. Tergum shining, the tympanal areas rather conspicuous and chocolate-colored. The succeeding segments blacker with the posterior margins faintly chocolate-colored. Last segment with a pruinose spot each side, and more conspicuously chocolate-colored than segments three to seven. Fore wing with the costal margin yellowish to the end of the radial cell, darker beyond; subcostal vein black; first and second cross veins slightly infuscated. The basal cell of each fore wing nearly clear, but blackened along the anterior margin. The flaps of both fore and hind wings are gray in color. Beneath pruinose, black about the eyes, where there are some long, silken, white hairs. The transverse rugse are yellowish and somewhat blackened where they join the shallow frontal sulcus. The legs are chocolate-colored with lighter spots and dashes, the hind pair being lighter colored than the other two pair. The opercula are pruinose, the lower extremities of the inner margins not quite touching, and the ends rounded. The ventral segments are dark chocolate-colored, central ones being lighter posteriorly. The last segment is rounded at the extremity and the valve is black. The external parts of the genitalia chocolate-colored and black.
