Fiji Periodical Raiateana Tacuini (Cryptotympanini)

Fiji 8-year periodical Nanai aka Raiateana knowlesi

Fiji $100 note

This cicada will next emerge in 2025.

Update (11/4/2017): from Facebook, it looks like folks are finding them. Here’s an image.

Update (9/13/2017): the Nanai have begun to emerge! This cicada last emerged in 2009 in Nadroga-Navosa and Serua Provinces, and now again emerge in 2017.

Notes from Chris Simon:

Early this morning I got the first Reports of the 8-year periodical Nanai emerging in Navosa, Fiji! Some people in that area had them for dinner.

This confirms earlier reports of the eight-year periodicity. There was some uncertainty because the original specimens were dated (1906) a year later than they would be if on the current 8-year schedule.

Duffels and Ewart (1988, The Cicadas of the Fiji, Samoa, and Tonga Islands, their taxonomy and Biogeograohy) noted that “Until recently the present species is only known from three males collected in “Fijii” in 1906 by C. Knowles.” Duffels was not able to describe them when he first saw the specimens because they were missing the male genitalia. After obtaining, “a series of females and two males” from Dick Watling and Andrew Laurie in 1986, Duffels was able to assign it to the genus Raiateana. There is one other species of Raiateana in Fiji, R. kuruduadua (two subspecies in Fiji and one in Samoa) but it is not periodical as far as we know.

You might be familiar with American periodical cicadas (Magicicada) and the World-cup synchronized Chremistica ribhoi of India, but Fiji has a periodical cicada too: the 8-year periodical Nanai cicada aka Raiateana knowlesi.

It also appears on Fiji’s $100 note.

There’s even a local legend about the cicada.

Australia Cicadettini Clinopsalta L. W. Popple Papers and Documents

New species of Clinopsalta cicadas

Lindsay Popple announced on Twitter that two new species of Clinopsalta cicadas have been described.

Sounds: Calling songs of Clinopsalta cicadas.

Journal Article: TWO NEW SPECIES OF CLINOPSALTA MOULDS (HEMIPTERA: CICADIDAE) AND ADDITIONAL DISTRIBUTION RECORDS FOR CLINOPSALTA ADELAIDA (ASHTON), WITH NOTES ON THEIR DISTINCTIVE CALLING SONGS. Popple and Emery, 2017. Rec. Aust. Mus. 69(4): 237—256

Abstract from the journal article:

Two new species are described in the genus Clinopsalta Moulds. Clinopsalta autumna sp. nov. exhibits a warm temperate distribution from south-east Queensland south to Goulburn and Nerriga in eastern New South Wales. Clinopsalta semilunata sp. nov. has a patchy distribution in southern Queensland from Binjour Plateau west to near Miles, south to Yelarbon State Forest and Durikai State Forest, both near Inglewood. In addition to the descriptions of these new species, further distribution records are provided for C. adelaida (Ashton), which extend its distribution from south-eastern South Australia and northern Victoria to inland central and northern New South Wales. The species of Clinopsalta are small—medium sized cicadas (< 20 mm body length) with distinctive calling songs of an intermediate frequency (c. 6 to 18 kHz). The temporal structures of the calling songs follow a similar pattern in each species, comprising an introductory rattle followed by a series of clicking phrases. The call is characteristically accompanied with bouts of prominent wing-snapping, except in one species (C. semilunata sp. nov.).

Cicada 3301 cicada compared to Distantalna splendida

Today I took a fresh look at the 3301 Cicada image. In the past I thought it was a composition of multiple cicadas — and it still might be — but I now think it’s primarily a Distantalna splendida formerly Tosena splendida, a cicada found in southern Asia (China, India, Burma, Thailand, Vietnam, etc.). Distortions caused by embossing — or whatever filters they used — make identifying the cicada difficult.

Here’s my comparison of the wings.

cicada 3301

I will probably do a comparison of the body and head at some point.

Here’s a photo of this Splendid cicada:
splendida

Specimens vary in appearance (size, wing patterns) from individual to individual — they all look similar, but they’re not exact matches. The process of spreading a specimen’s wings and preserving it can also alter its appearance, and introduce unnatural changes to the insect’s morphology.

Distantalna splendida are easy to find on eBay or taxidermy shops if you’re interested, although they’re often mislabeled using their former name Tosena splendida, or something totally different.

Bonus:

Here’s an illustration from A Monograph of Oriental Cicadas by W. L. Distant. 1889-1892. Read it on the Biodiversity Heritage Library website:

New Cicada: Berberigetta dimelodica

Thanks to Vera L. Nunes for letting us know about a newly described/discovered cicada named Berberigetta dimelodica.

Berberigetta is also a new genus, belonging to the Tribe Cicadettini.

See and listen to it in this YouTube video:

The paper than describes the species is:

Gonçalo João Costa, Vera L. Nunes, Eduardo Marabuto, Raquel Mendes, Telma G. Laurentino, José Alberto Quartau, Octávio S. Paulo, Paula Cristina Simões. 2017. Morphology, songs and genetics identify two new cicada species from Morocco: Tettigettalna afroamissa sp. nov. and Berberigetta dimelodica gen. nov. & sp. nov. (Hemiptera: Cicadettini). Zootaxa. Vol 4237, No 3.

Link to the Zootaxa page for the document.

And here’s a quote of the Abstract:

Morocco has been the subject of very few expeditions on the last century with the objective of studying small cicadas. In the summer of 2014 an expedition was carried out to Morocco to update our knowledge with acoustic recordings and genetic data of these poorly known species. We describe here two new small-sized cicadas that could not be directly assigned to any species of North African cicadas: Tettigettalna afroamissa sp. nov. and Berberigetta dimelodica gen. nov. & sp. nov. In respect to T. afroamissa it is the first species of the genus to be found outside Europe and we frame this taxon within the evolutionary history of the genus. Acoustic analysis of this species allows us to confidently separate T. afroamissa from its congeners. With B. dimelodica, a small species showing a remarkable calling song characterized by an abrupt frequency modulation, a new genus had to be erected. Bayesian inference and maximum likelihood phylogenetic analyses with DNA-barcode sequences of Cytochrome C Oxidase 1 support the monophyly of both species, their distinctness and revealed genetic structure within B. dimelodica. Alongside the descriptions we also provide GPS coordinates of collection points, distributions and habitat preferences.
