Orientopsaltria alticola (Distant, 1905) is a cicada found on Borneo (Brunei, Indonesia, Malaysia).

Champaka viridimaculata (Distant, 1889)

Champaka viridimaculata (Distant, 1889) is a cicada found on Borneo (Brunei, Malaysia, Indonesia). Viridimaculata means green spotted in Latin — perhaps that is a reference to the green coloring in the cells of the wings near its body.

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Dundubiini
SubTribe: Dundubiina
Genera: Champaka
Species: Champaka viridimaculata (Distant, 1889)

Champaka viridimaculata (Distant, 1889)

Champaka genus description by W. L. Distant in Genera Insectorum, 1913:

Characters. — Head (including eyes) considerably broader than base of mesonotum, its length about equal to breadth between eyes, lateral margins of front and vertex almost obliquely in line; pronotum about as long as head, its lateral margins armed with a distinct medial spine ; mesonotum moderately tumid ; abdomen considerably longer than space between apex of head and base of cruciform elevation ; tympana covered, tympanal coverings broader than long; opercula short. just reaching basal abdominal segment, laterally oblique and thus exposing the marginal areas of the cavities rostrum reaching the posterior coxae; anterior femora strongly spined beneath ; tegmina and wings hyaline, the first considerably longer than the body and with its greatest breadth considerably less than a third of its length; apical areas eight; basal cell longer than broad.

Ayesha serva (Walker, 1850)

Ayesha serva (Walker, 1850) is a cicada found in the Philipines and on Borneo (Brunei, Malaysia and Indonesia), and Korea?

This one is interesting. Back when Distant wrote the Homoptera. Fam. Cicadidae, Subfam, Cicadinae. found in Genera Insectorum, 1932, there were two cicada species: Ayesha serva, found in the Philipines and Borneo, and Ayesha spathulata found in Korea. Today both species are unified under Ayesha serva. There’s a large distance between Korea and Borneo, so this makes me wonder, was A. serva actually ever in Korea, or are they two different cicadas?

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Dundubiini
SubTribe: Dundubiina
Genera: Ayesha
Species: Ayesha serva (Walker, 1850)

Ayesha serva (Walker, 1850)
The image says Ayesha spathulata, but the newer name of this cicada is Ayesha serva.

Ayesha genus description by W. L. Distant from Genera Insectorum, 1913:

Characters. — Head (including eyes) as wide or a little wider than base of mesonotum, much shorter than breadth between eyes, lateral margins obliquely continuous to face or very slightly sinuate, eyes large and oblique; pronotum shorter than mesonotum, its lateral margins angulated anteriorly; mesonotum moderately convexly tumid; abdomen short, not longer than space between apex of head and base of cruciform elevation; tympanal coverings about as long as broad; rostrum reaching the intermediate coxae; opercula in male long, about twice as broad at apex as at base, inner .margins concave, widening to basal area, outer margins sinuate near centre, their apices broad overlapping;tegmina and wings hyaline, greatest width of tegmina about one third their length.

SubFamily: Cicadinae
Tribe: Cicadatrini
Genera: Mogannia
Species: Mogannia binotata Distant, 1906

Tacua speciosa

The Tacua speciosa is a beautiful cicada native to the countries Malaysia & Indonesia, and the islands Borneo & Sumatra, and likely other islands and nations of the area. Tacua speciosa are well known for their large size, opaque wings, black body, striking yellow/chartreuse pronotal collar, red cruciform elevation, and cyan or yellow tergites. There are two subspecies.

The name speciosa comes from the Latin word “specios” which means beautiful or showy.

Tacua speciosa from Malaysia (peace)

Scientific classification:
Family: Cicadidae
SubFamily: Cicadinae
Tribe: Tacuini
Genera: Tacua
Species: Tacua speciosa
SubSpecies: Tacua speciosa decolorata Boulard, 1994
SubSpecies: Tacua speciosa speciosa (Illiger, 1800)

Here is W.L. Distant’s description of this insect from A monograph of oriental Cicadidae:

Body above black ; eyes, anterior pronotal margin (narrowly), posterior margin of pronotum, posterior margin of the third, and the whole of the fourth, fifth and sixth abdominal segments, ochraceous ; basal cruciform elevation red, with its anterior angles black ; body beneath black ; lateral areas and margins to prosternum, a spot at lateral margins of third abdominal segment, and the lateral margins of the fourth, fifth and sixth abdominal segments, ochraceous. Tegmina black, coastal membrane and venation dull reddish, outer margin narrowly creamy-white wings black, the outer margin (excluding anal area) creamy-white. Var. a. Tegmina and wings greyish-brown, the black coloration only observable at margins of the veins. Long.excl.tegm. 47 to 57 millim. Exp.tegm.150 to 180 millim.

Two Distinct Types:

This image comes from A Monograph of Oriental Cicadas by W. L. Distant. 1889-1892.
Tacua speciosa
Which is which in the photos and illustrations on this page? Can you tell?

Normal form (#9 in the image): “Tegmina [forewings] black, coastal membrane and venation dull reddish, outer margin narrowly creamy-white wings black, the outer margin (excluding anal area) creamy-white.”

Variety A (#10 in the image) “Tegmina and wings are greying-brown, the black coloration only observable around the veins.”

Size:

T. speciosa is one of the largest cicadas. According to the Distant’s description above — tegm.[forewings] 150 to 180 millim. That’s 5.9 to 7.1 inches. According to my own collection (I have 2). The male is 160mm (6.3″), and the female is 142mm (5.7″). Both are smaller than the Megapomponia and largest Tosena in my collection. T. speciosa cicadas are big, but not the biggest.

Song:

A video of a singing T. speciosa:

The only document specifically about the T. speciosa I’ve found is Boulard, M. 1994c. Tacua speciosa, variete decolorata n. var. (Homoptera, Cicadidae). Revue Française d’Entomologie. 16: 66. — however, that document usually costs around $60, which I’m not ready to invest in (I’ll spend the money on cicadas).

When and Where

The iNaturalist page for Tacua speciosa shows sightings on the islands of Sumatra and Borneo, and the Malay Peninsula.

Peak times are March-April.

At one point in time, the Tacua speciosa was one of the most illustrated cicadas:

Pop Culture

Pop culture note: this species of cicada was featured on the Wednesday, January 16, 2013 episode of the Daily Show. It is not, however, a 17-year cicada. :) T. speciosa probably has a 2-7 year lifecycle and is not a periodical cicada, but it might be proto-periodical (but most likely is an annual species).
