Neotibicen similaris apalachicola, a new cicada subspecies

Filed under: David Marshall | Kathy Hill | Neotibicen | Papers and Documents | United States — Tags: — Dan @ 6:28 am

A new subspecies of the Similar Dog-Day Cicada has been described in the paper A new Neotibicen cicada subspecies (Hemiptera: Cicadidae) from the southeastern USA forms hybrid zones with a widespread relative despite a divergent male calling song by David C. Marshall and Kathy B. R. Hill (Zootaxa, Vol 4272, No 4). The cicada is named Neotibicen similaris apalachicola.

This cicada lives in Florida, Georgia & Alabama, and hybridizes with the other Similar Dog-Day Cicada sub-speces, Neotibicen similaris similaris. The document is available on biotaxa.org.

A morphologically cryptic subspecies of Neotibicen similaris (Smith and Grossbeck) is described from forests of the Apalachicola region of the southeastern United States. Although the new form exhibits a highly distinctive male calling song, it hybridizes extensively where it meets populations of the nominate subspecies in parapatry, by which it is nearly surrounded. This is the first reported example of hybridization between North American nonperiodical cicadas. Acoustic and morphological characters are added to the original description of the nominate subspecies, and illustrations of complex hybrid song phenotypes are presented. The biogeography of N. similaris is discussed in light of historical changes in forest composition on the southeastern Coastal Plain.

You will find song samples and maps on the Insect Singers website.

I think this is an image of the new cicada:

Brood VI 17-Year Cicadas Due in Spring of 2017

Filed under: Brood VI | Magicicada | Periodical — Dan @ 1:01 am

Brood VI will next emerge in 2034.

This page was last updated in 2017.

Final Update: I traveled to Wisconsin last week and spent a few days looking for cicadas in the southern part of the state (Madison, Baraboo, Janesville, Cedar Bluff, Dodgeville) but unfortunately I did not see or hear any. :(. So far this year though, Brood VI was spotted in GA, NC, SC, OK, OH and perhaps NY….

BROOD VI

Previous updates can be found in the comments.

Brood VI (6) 17-year cicadas (“locusts”) will emerge in the spring of 2017. The main group will emerge in South Carolina, North Carolina and Georgia. Other lesser groups should emerge in Ohio & Wisconsin. And possibly other states/locations as well.

About Brood VI:

The cicada species that will emerge are Magicicada septendecim1, Magicicada septendecula1, and possibly Magicicada cassini2. These periodical cicadas have a 17-year life cycle. The last time they emerged was 2000.

When: Generally speaking, these cicadas will begin to emerge when the soil 8" beneath the ground reaches 64 degrees Fahrenheit 3. A nice, warm rain will often trigger an emergence. So, definitely May, but something might happen in April if we have a particularly hot spring.

Report a sighting: If you see or heard cicadas, please report them to Cicadas @ UCONN (formerly Magicicada.org). This helps researchers map the location of the cicadas.

Locations where they are likely to emerge:

New Cicada: Berberigetta dimelodica

Filed under: Africa (Continent) | Berberigetta | Cicadettini | Vera L. Nunes | Video — Tags: — Dan @ 10:24 am

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.

Quick guide to recent cicada name changes

Filed under: Genera — Dan @ 8:31 am

The names of cicadas change a lot. I don’t question the name changes, but it does take a fair amount of time to update 100s-1000s of pages on this site whenever a genus or species name changes, or when a species is split into multiple species or a genus is split into multiple genera. There are likely places on this site where the names are a generation or two behind.

Here’s a guide to changes from the past two decades. It is far from complete, but it represents the more well-known cicadas.

Genus changes

Auritibicen spawned from Tibicen/Lyristes. These cicadas include:

Twelve Auritibicen bihamatus subspecies, five Auritibicen flammatus subspecies, Auritibicen intermedius Mori, 1931, ten Auritibicen japonicus subspecies, Auritibicen kyushyuensis (Kato, 1926), Auritibicen pekinensis (Haupt, 1924), and Auritibicen slocumi Chen, 1943.

Read Young June Lee. 2015. Description of a new genus, Auritibicen gen. nov., of Cryptotympanini (Hemiptera: Cicadidae) with redescriptions of Auritibicen pekinensis (Haupt, 1924) comb. nov. and Auritibicen slocumi (Chen, 1943) comb. nov. from China and a key to the species of Auritibicen. Zootaxa 3980 (2): 241—254.

Callogaena spawned from Gaeana Amyot & Audinet-Serville, 1843. Although Gaeana might still be preferred. Here is a Callogaeana festiva.

Distantalna Boulard, 2009 spawned from Tosena Amyot & Audinet-Serville, 1843. Here is a Distantalna splendida. This cicada is very common on eBay and found in a lot of arts and crafts, and is still mostly called Tosena splendida in those places.

See the image below: Distantalna clearly lacks the angular forewing stripes of Tosena. The orientation of the eyes seems very different as well.

Compare

Lyristes. Depending on what area of the world you’re in, the genus Tibicen is often replaced with Lyristes. Prior to the introduction of Auritibicen in 2015, the Tibicen of Asia were called Lyristes. The Tibicen of Europe are called Lyristes as well, like Lyristes plebejus (Scopoli, 1763). The genera of North American Tibicen have all changed as well. I’m not up on the debate but I believe Michel Boulard is advocating for Lyristes. I think the argument against the name was that Latreille came up with Tibicen in 1925, and Horváth came up with Lyristes a century later in 1926. So if you see Lyristes, consider it to be a synonym of Tibicen, Auritibicen, Hadoa, Neotibicen, Megatibicen, etc.

Megapomponia Boulard, 2005 spawned from Pomponia Stål, 1866. Here is a Megapomponia imperatoria. Megapomponia are the largest cicadas so MEGA (from the Greek megas which means “great, large, mighty”) makes sense.

Neotibicen Hill & Moulds, 2015 and Hadoa Moulds 2015 spawned from Tibicen.

Read Hill, et al. 2015. Molecular phylogenetics, diversification, and systematics of Tibicen Latreille 1825 and allied cicadas of the tribe Cryptotympanini, with three new genera and emphasis on species from the USA and Canada (Hemiptera: Auchenorrhyncha: Cicadidae), Zootaxa, Volume 3985, Issue 2, Pages 219—251.

Megatibicen Sanborn and Heath 2016 spawned from Neotibicen, which of course spawned from Tibicen.

Read: Sanborn A.F., Heath, M.S. 2016. Megatibicen n. gen., a new North American cicada genus (Hemiptera: Cicadidae: Cicadinae: Cryptotympanini), Zootaxa, Volume 4168, Issue 3.

Gigatibicen Lee 2016, Ameritibicen Lee 2016, and Paratibicen Lee 2016 spawned from Neotibicen, although it seems like Megatibicen will be preferred over Gigatibicen and Ameritibicen. Lee, Y.J. 2016. Description of three new genera, Paratibicen, Gigatibicen, and Ameritibicen, of Cryptotympanini (Hemiptera: Cicadidae) and a key to their species Journal of Asia-Pacific Biodiversity, Volume 9, Issue 4, 1 December 2016, Pages 448—454.

Here’s a pretty good chart that explains the Tibicen/ Neotibicen/ Megatibicen/ Gigatibicen/ Ameritibicen/ Paratibicen stuff.

Species changes

Magicicada neotredecim Marshall and Cooley 2000 spawned from Magicicada tredecim (Walsh and Riley, 1868) in 2000 when David Marshall and John Cooley described it as its own unique species. Read Marshall, D.C. & Cooley, J.R. (2000). Reproductive character displacement and speciation in periodical cicadas, with a description of a new species, 13-year Magicicada neotre- decim. — Evolution 54, p. 1313-1325.

Neotibicen tibicen australis (Davis, 1912) was once Tibicen tibicen australis (Davis, 1912) when Neotibicen (genus) spawned from Tibicen in 2015. Prior to the change, this cicada was Tibicen chloromerus var. australis. Read: Tibicen tibicen australis Sanborn, Phillips and Gillis 2008: 4—5, 12, 31, 39, Fig 73, Figs 139—147 (key, synonymy, illustrated, distribution, comp. note) Equals Rihana sayi var. australis Florida, Georgia

Neotibicen tibicen tibicen (Linnaeus, 1758) was called Tibicen chloromera, but then Allen Sanborn (I think) switched it to Tibicen chloromerus (a to an us for correct gender grammar of the species name) in the late 1990s. Then around 2008 Sanborn switched it to Tibicen tibicen because the original name dating back to 1758 was Cicada tibicen.

Megatibicen pronotalis pronotalis Davis, 1938 and Megatibicen pronotalis walkeri Metcalf, 1955 have had a number of changes. Aside from two to three recent changes genus changes, species names have changed as well. Megatibicen pronotalis pronotalis has been called Tibicen walkeri var. pronotalis, Tibicen marginalis var. pronotalis, Tibicen pronotalis walkeri and Tibicen walkeri pronotalis. Megatibicen pronotalis walkeri has been called Tibicen marginalis, Tibicen walkeri, and even Lyristes marginalis. Yikes!

That’s a lot of changes. I used Allan Sanborn’s book Catalogue of the Cicadoidea to verify much of this information. It’s a huge book. No photos, mostly cicada names. 🙂

Editorial: I know a lot of folks are bemused and vexed by these name changes, and many still use the old names. Certainly Tibicen chloromera, regardless of its taxonomic faults, sounds better than Neotibicen tibicen tibicen. Of the changes described above, my favorites (can you have favorites in science?) are Magicicada neotredecim Marshall and Cooley 2000 which is definitely a different insect than Magicicada tredecim (Walsh and Riley, 1868); and Distantalna Boulard, 2009 because Distantalna splendida looks very different than cicadas belonging to the genus Tosena, IMHO.

New species of Megatibicen: Megatibicen harenosus

Filed under: Jeffrey A. Cole | Megatibicen | Tibicen — Dan @ 6:32 am

A new species of Megatibicen, named Megatibicen harenosus sp. n., has been described by Jeffrey A. Cole. It lives in the Mescalero-Monahans shinnery sands areas of New Mexico and Texas. It is very similar to Megatibicen (Neotibicen, Tibicen) tremulus, which itself looks a lot like dorsatus and dealbatus.

Here’s a link to the announcement of the paper. This is the abstract:

Megatibicen harenosus sp. n. is described from the Mescalero-Monahans shinnery sands of New Mexico and Texas, U.S.A. The new species is diagnosed from similar species, especially M. tremulus which it resembles closely, by male genital morphology, color pattern, calling song, and ecology. Seven characters from the male calling song are described from analysis of field recordings, of which all four temporal song characters are significantly different from M. tremulus. With one of the most southwestern distribution of any Megatibicen species, M. harenosus is a new addition to the rich, endemic, and understudied Mescalero-Monahans shinnery sands biota. The possibility that M. harenosus and M. tremulus are sister species is raised. The ecological, biological, and evolutionary species concepts support species status for M. harenosus, and an hypothesis of peripatric speciation in peripheral isolation is advanced.

There is a sample of this cicada’s song on the Insect Singers website. Check it out.

Gigatibicen, Ameritibicen, Paratibicen

Filed under: Lyristes | Megatibicen | Neotibicen | Tibicen | Young June Lee — Dan @ 11:10 am

Gigatibicen
For some reason I associate “Giga” with “Gigabytes” and storage media like Flash drives, which explains this joke image.

Over the past two years there have been quite a few updates to the genera of the cicadas that were organized under the Tibicen genus earlier this decade.

The most recent paper by Young June Lee introduces the genera Gigatibicen, Ameritibicen, and Paratibicen 1. Earlier this year there was a paper by Allen Sanborn and Maxine Heath that introduced the genus Megatibicen 3, and in 2015 there was a paper by Kathy Hill and others that introduced Neotibicen and Hadoa 2.

See the end of the article for links to these papers, and related articles on CicadaMania.com.

A New Tribe for the Hammer-Head Cicada

Filed under: Cicadmalleus | Michel Boulard | Stephane Puissant — Dan @ 4:28 am

A new paper by Michel Boulard & Stéphane Puissant has been released that describes Cicadmalleus micheli, aka the Hammmer-Head cicada of Thailand. As the name of the cicada suggests, the cicada’s head resembles a hammer. The cicada gets a new Tribe as well: Cicadmalleini.

What is Megatibicen?!

Filed under: Allen F. Sanborn | David Marshall | Maxine E. Heath | Megatibicen | Neotibicen — Dan @ 9:39 am

Update (9/20): I guessed the species correctly: all the Large Flute Players.

Update (9/24): I neglected to note that there’s another paper out there by Young June Lee called Description of three new genera, Paratibicen, Megatibicen, and Ameritibicen, of Cryptotympanini (Hemiptera: Cicadidae) and a key to their species. Link to it here. This manuscript goes beyond one new genus, and instead introduces three: Paratibicen, Megatibicen, and Ameritibicen. Lee’s paper differs from Sanborn & Heath in that the large Neotibicen are spit into Megatibicen and Ameritibicen in Young’s document, but they’re all Megatibicen in Sanborn & Heath’s paper.

Megatibicen

Last night I had a rough night’s sleep. I tossed and turned all night long. I remember looking at the clock and seeing 4 am, and thinking “tomorrow is ruined”. Sometime during the night I dreamt of finding thousands of molted Neotibicen exuvia clinging to shrubbery — a rare if not impossible sight in real life.

When I woke I checked my email and found a communication from David Marshall. David is well known and respected in the cicada world for many things including describing the 7th species of Magicicada with John Cooley, as well as being part of the team who defined the Neotibicen and Hadoa genera (link to paper)1.

David wrote to let me know that Allen F. Sanborn and Maxine S. Heath had published a new paper titled: Megatibicen n. gen., a new North American cicada genus (Hemiptera: Cicadidae: Cicadinae: Cryptotympanini), 2016, Zootaxa Vol 4168, No 3.(link).

So, what is MEGATIBICEN? Assumptions after the abstract.

Here is the abstract:

The genus Tibicen has had a confusing history (see summary in Boulard and Puissant 2014; Marshall and Hill 2014; Sanborn 2014). Boulard and his colleague (Boulard 1984; 1988; 1997; 2001; 2003; Boulard and Puissant 2013; 2014; 2015) have argued for the suppression of Tibicen and the taxa derivatived from it in favor of Lyristes Horváth. Boulard’s argument for suppression was first described in Melville and Sims (1984) who presented the case for suppression to the International Commission on Zoological Nomenclature with further comments made by Hamilton (1985), Boulard (1985), and Lauterer (1985). A lack of action resulted in additional comments being published in 2014 again supporting the retention (Sanborn 2014; Marshall and Hill 2014) or the suppression (Boulard and Puissant 2014) of Tibicen.

My guess, without reading the document, is that Megatibicen includes the larger North America Neotibicen species, including the “auletes group” (M. auletes, M. resh, M. figuratus, M. resonans), the “pronotalis group” (M. pronotalis, M. dealbatus, M. cultriformis) and the “dorsatus group” (M. dorsatus, M. tremulus), or a mix of these. M. auletes is the largest cicada in North America. “Mega” is the Greek word for “very large” or “great”. Word is that Kathy Hill and David Marshall also planned on describing a Megatibicen genus at one point, as well.

Whenever cicada names change it causes feelings of bemusement, discontentment, and discomfort amongst some cicada researchers and fans. I know I don’t like it because I have to update the names of cicadas in 100’s of places on this website ;). Some folks simply disagree with the folks writing the paper. Some people prefer former names because they sound nicer (e.g. N. chloromerus vs N. tibicen tibicen). Some people simply do not like change.

Related: Here’s my article on when Neotibicen & Hadoa were established from Tibicen.

Last cicada hunt of the year

Filed under: Neocicada — Tags: , — Dan @ 7:31 pm

Once September rolls around in New Jersey (USA) temperatures start to drop, as do the cicadas. Labor Day weekend is a three day last hurrah for the summer. Folks have barbecues, take one last trip to the beach, or one last fishing trip to the lake. It’s one last chance to have some fun before the kids go back to school, the weather gets too cold to wear shorts, and hurricanes start ripping up the coastline. This past Labor Day weekend I found myself at Washington Crossing State Park in Titusville, NJ. You might have guessed that this park marks the location where founding father General George Washington famously crossed the Delaware River. I think of it was a place to find Neotibicen linnei and Neotibicen winnemanna in the same location.

Some video of their calls:

N. linnei and N. winnemanna belong to the “Green Group” of Neotibicen cicadas. All the cicadas in this group look very similar, and you have to tell them apart by their song or key morphological differences. Even with sound files of their songs to reference, photos and notes, telling them apart can be vexing and bemusing. In some cases species mate and form hybrids which make it even more difficult to tell them apart.

Some images:

A is likely an N. linnei, and C is likely an N. winnemanna.

wings of Linne and Scissor Grinder

Probably an N. linnei although it lacks the wing bend. More black than beige, although that isn’t always a sure indicator of species.
Washington Crossing Neotibicen linnei

Definitely an N. winnemanna because of all the beige on its abdomen. Yes, its head is missing,
N. winnemanna

After wandering the park for a few hours I was rewarded with a few dead specimens. One with eggs still stuck to its ovipositor, which was neat to see. I also recorded their calls — unfortunately no hybrids in the mix.

Part of the fun of traveling to see cicadas is visiting the place where the cicadas live. Washington Crossing State Park is far from the industry and urban decay New Jersey is known for. If you like scenic rivers, pastoral landscapes, American history, farmers markets, and antique stores, this area is for you. For me, it’s a nice place to observe cicadas. The park features many acres of deciduous and evergreen trees, perfect for cicadas. You can also walk the bridge to the Pennsylvania side of the river, where you’ll find more N. winnemanna than N. linnei.

Cicadas will be done mating before the end of September (actual date differs by location), and start dropping from the trees before the leaves being to change color. Go out this weekend and look and listen for the last cicadas of the year.

Oh yeah, here’s the B cicada:

N. winnemanna
