Formotosena seebohmi (Distant, 1904) was formerly Tosena seebohmi. Its genus changed from Tosena Amyot & Audinet-Serville, 1843 to Formotosena Kato, 1925. Yes, its name name has changed since 1913! It is found in the Republic of China (Taiwan).
The image might say Tosena seebohmi, but the newest name for this cicada is Formotosena seebohmi.

Arunta perulata (Guérin-Méneville, 1831). Found in Australia. Known as a White Drummer. Like other members of the tribe Thophini, like Thopha colorata (Orange Drummer) and Thopha saccata (Double Drummer), they have massive sac-like tymbal covers, which is why they’re called drummers.
Characters. — Head transverse, moderately truncate in front of eyes, between eyes much narrower than base of mesonotum ; rostrum reaching the posterior coxae; pronotum moderate broad, its breadth considerably less than length of both pro- and mesonotum (including the basal cruciform elevation); tympana very largely developed and sac-like, their apices obliquely extending beyond the lateral margins of the abdomen and to about half its length; opercula very small, not extending to base of metasternum, placed wide apart, and with their apical margins convex; anterior femora incrassated and spined ; posterior tibiae with a few lateral fine spines; tegmina and wings talc-like, tegmina with eight apical areas.

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.
Recently updated Tribe information comes from: MARSHALL, DAVID C. et al.A molecular phylogeny of the cicadas (Hemiptera: Cicadidae) with a review of tribe and subfamily classification.Zootaxa, [S.l.], v. 4424, n. 1, p. 1—64, may 2018. ISSN 1175-5334. Available at: https://www.biotaxa.org/Zootaxa/article/view/zootaxa.4424.1.1
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. 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.
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).
At one point in time, the Tacua speciosa was one of the most illustrated cicadas:
Original Source: From Dictionnaire universel d’histoire naturelle. (Paris: Renard, 1841-1849) Orbigny, Charles d’, Author.
Original Source: From Animate creation : a popular edition of “Our living world” : a natural history. (New York: Selmar Hess, 1885) Wood, J. G. (John George) (1827-1889), Author.
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).
Ioba limbaticollis (Stål, 1863). Sub-Saharan Africa, West Africa, including Nigeria, Ghana, the Democratic Republic of the Congo, Central African Republic, and Ivory Coast. This cicada has an amazing pronotal collar.
Characters. — Head (including eyes) wider than the base of the mesonotum, not truncate anteriorly, but with the lateral margins of the vertex a little oblique on each side and the front prominently produced; pronotum transverse, its posterior margin only a little less in length than the vertex, the lateral margins strongly and angularly produced on each side, the angulations medial, their apices when the tegmina are expanded reaching near or to about the end of the basal cell; mesonotum about as long as the pronotum; anterior femora with; one or more distinct spines, posterior and sometimes intermediate tibiae spined on apical areas; metasternum elevated and centrally sulcated ; tympana covered; opercula short, broad, their apices more or less convexly rounded; rostrum reaching the posterior coxae; tegmina with the basal cell broad, irregular, with four, or sometimes five, angles ; ulnar veins widely separated at their bases; interior ulnar area somewhat broadened at apex.
